1. PLANNING A MODERN IMAGING
DEPARTMENT
ETHICS AND LEGAL ISSUES in
radiology
2. • Radiology department is one of the focal point of any hospital or a
medical centre and setting up such a facility requires a very
careful planning and a vision for the future.
• Scope of a modern radiology setup is not only limited to imaging
studies but also has a therapeutic role in the form of minimal
invasive interventional radiology setup.
3. STRATEGIC PLANNING
• Feasibility of setting up an imaging centre in a given area – 1st step
Need for such services in the given area
Presence of other centres
Status and acceptability of referring physicians
Presence of larger hospitals in area
• Further planning can be undertaken once it is clear that there is a need for the same
4. • 2 types of radiology centres -
Radiology departments in a hospital setting
Dedicated radiology centres, that works on referrals
• Difference – patient referral
5. LOCATION
• Preferably on the ground floor
• Sophisticated machines like CT and MRI are best placed on the ground floor
• In addition to walk in patients, the department also caters to emergency patients
who may not be able to walk or need urgent scanning for establishing the
diagnosis
• Should be easily accessible to
• OPD patients,
• inpatients
• emergency department.
7. EQUIPMENTS
• Digital X-rays
• Fluoroscopy units
• Mammography unit
• Dual energy X-ray absorptiometry (DEXA) unit
• Ultrasonography units
• Multislice CT
• 1.5 T/3 T MRI
• Digital subtraction angiography unit
• Positron emission tomography – computed tomography (PET-CT)
12. RECEPTION AREA
• Patient entering should immediately know where
to go /approach
• Well lit,
• adequate space for
• sitting
• trolleys and wheel chairs
• Person-in-charge
• qualified and well versed with various types of
radiological studies;
• prime responsibility of scheduling the studies for the
patients
RECEPTION
13. PREPROCEDURE AND CHANGING ROOMS
• Nearly every radiological investigation needs some type of
preparation
• To remove any metallic clips or rings for X-rays
• Changing into hospital gown
• Screening for any metallic item on the patient before MRI
14. INVESTIGATION ROOMS
• A modern radiological setup should have minimum of
1. one digital X-ray unit,
2. one fluoroscopic unit and
3. one mammographic unit,
4. one sonographic unit,
5. one CT scan,
6. one MRI unit
• X-ray, fluoroscopic and CT scan emit ionising radiation special
care required for construction of rooms

48. ULTRASONOGRAPHY ROOM
• Since ultrasound machines do not emit any ionising radiation, it is possible to house
them in a general room without any special construction guidelines.
• A well designed sonography room should have
• ambient light control,
• an examination trolley/bed,
• a changing room and
• a washroom
49. MRI ROOM
• MR machine contains a large magnet, which emits strong magnetic field in all
directions, so its installation and housing is different from any other radiological
equipment.
• An MR unit has to be shielded in such a way that its magnetic field does not exist
outside the room
• active shielding,
• passive cladding and room shielding are done.
• For patient safety, the access to the MR room should be controlled and clear printed
instructions should be displayed at the point beyond which only patients with
adequate screening can go.
50. MRI ROOM
• In any MR installation, it is necessary to see the effect of emitted magnetic field in
all directions.
• Any device or equipment, which is sensitive to magnetic fields, should be away from
the MR unit or adequately shielded (e.g. Power transformers, CT scanners,
ultrasound equipment, etc.)
• Special planning is done to see that the MR unit is away or well shielded from
• steel pipes and structural steel.
• Since device that RF waves, e.g. cell phones, radio transmitters, etc., can cause
interference in image reconstruction, the MR unit also needs to be shielded from RF
pulses.
52. REPORTING ROOM
• In a modern department, nearly all reporting is done on dedicated workstations.
• Different from conventional setups where first X-ray, CT or MRI images are
printed on films and then send for reporting.
• A filmless setup is
• cheaper,
• environment friendly,
• easier to maintain and useful.
• Big enough to house separate reporting consoles for all radiologists who are
working.
• Their consoles should be independent and at the same time should be
designed in a way that interpersonal communication is not hindered
53. ADVANCES IN RADIOLOGY SETUP
• MOVING TO FILMLESS RADIOLOGY
• Instead of printing films, the images are viewed on monitor for reporting
and then given to patients either in CDS or paper prints or sent to referring
doctors electronically via net to their computers.
• Achieved in two ways –
• Images can be acquired digitally with the use of modern equipment or
• images can be digitalised by scanning the films.
Conventional X-ray images Digital X-ray images
If factors like tube voltage and current are not
optimal, the image on the films may not be useful
X-ray needs to be repeated, giving patients
additional dose of radiation
The image can be manipulated, even if acquisition
is not optimal repeat X-ray can be avoided
Storage of films takes a lot of space and can get
degraded with time
Images can be stored very easily for years
together and can be sent electronically to higher
centres for second opinion
54. PACS AND HIS
• For achieving rapid reporting, transfer and storage of images, a system
called PACS is installed.
• PACS – Patient Archiving and Communication System
• The radiology machines are lined to a central server where all the images
are sent. From there, the images are sent for long term storage and also
for reporting to individual workstations of the radiologists.
• PACS is linked to HIS (Hospital Information System) in larger hospital
setups.
• The acquired images can be made available to the referring physicians
very soon after they are acquired. Also, the radiologists have access to the
clinical and laboratory details of the patients, which go a long way in
reaching to a correct diagnosis
56. • Radiology is a specialized branch of medicine using medical imaging
technologies to diagnose and treat patients.
• Like other specialties, radiologists are also liable to claims of malpractice
due to diagnostic errors.
• Errors in radiology differ from errors in other clinical specialities as in
that, the radiological image is a permanent objective record that can be
reviewed to check for missed lesions.
• Such errors, when causes significant damages to the patients, in the form
of injury or death, attract malpractice claims.
57. • Apart from the medical malpractice, another important area of
legal importance for Indian radiologists is Pre-conception and Pre-
natal Diagnostic Techniques Act (PCPNDT- Act) which has stringent
rules and regulations to curb female feticide.
• It is important to follow and strictly adhere to the guidelines laid
down under the act to avoid legal actions.
58. MEDICAL MALPRACTICE AND RADIOLOGY
• The term “medical malpractice” refers to the professional negligence of doctors,
surgeons, nurses and other healthcare professionals. This is the most common
complaint registered against a doctor.
• Medical malpractice is said to have occurred when the healthcare professional
discharged a substandard level of care and, as a result of which the patient
suffered damages.
• The three essential components to prove medical malpractice lawsuits are
• breach of duty,
• causation and
• resulting damage.
59. • Radiologic errors in diagnosis can be of two types,
1. cognitive and
2. perceptual errors.
• Cognitive errors are those in which an abnormality is seen but its nature is misinterpreted.
• Perceptual errors or the radiologic ‘miss’, are the one in which a radiologic abnormality is not
seen by the radiologist on initial interpretation.
• Of the two types, perceptual errors resulting in false-negative errors are the most frequent
accounting for 80% and the majority of which includes failure to diagnose
• breast cancer on mammography,
• lung nodules on chest x-ray and
• fractures on skeletal radiographs.
60. • Not all missed findings represent the breach in standard of care.
• When the radiologist reviews an imaging study obtained with
• proper technique and exposure and fails to perceive an abnormality, which, in retrospect, is
apparent, such ‘error in perception’ cannot be labelled negligence.
61. • Other infrequent causes –
Failure to alert or communicate with the referring clinicians of important but
unsuspected findings
Failure on the part of the radiologist to suggest appropriate next procedure when
diagnostic specificity is required
Incorrect examinations obtained on patients
• Once a person claims a malpractice who is referred to as ‘plaintiff’, should establish the
existence of all the three elements of malpractice i.e.
• breach of duty,
• causation and
• damages.
• If any one element is missing, then the malpractice claim is not valid.
62. Radiologist as a defendant in malpractice claim:
• Do not panic or lose confidence when a malpractice is claimed. One
should act calmly.
• On receiving such court notice, the document should be read carefully
to determine the nature of claim.
• Later, assemble all the related documents i.e. physician referral
form, consent form, acquired images, reports etc.
• Do not alter any medical records.
• Immediately contact the medical defense lawyer and insurer.
• An investigation committee will be formed which includes renowned
and senior doctors who are experts in the particular discipline.
• Depending on the committee opinion, if the radiologist is proved
negligent, necessary action will be taken up according to the nature
of act.
63. In Indian Law, doctors can be held responsible under:
• Civil suit consumer court: Consumer protection act (CPA) considers
patient seeking medical care as ‘consumer’ and doctors attending to
it as ‘service provider’. Doctor-patient relationship/contract is
bound to CPA.
• Case in medical council: A case against a doctor can also be filed in
medical council of the concerned system of medicine. Medical
Councils do not have powers to award compensation or to imprison.
It can only warn the doctor, suspend or revoke the license.
• Case of criminal negligence: The main section under which a criminal
case is filed against doctors is Section 304A of the Indian Penal Code
which deals with causing death due to rash and negligent act. The
punishment is two years imprisonment or fine or both.
• Law of Torts
64. • “The standard to be applied for judging, whether the person charged has been
negligent or not, would be that of an ordinary competent person exercising
ordinary skill in that profession.
• It is not possible for every professional to possess the highest level of expertise or
skills in that branch which he practices.
• A highly skilled professional may be possessed of better qualities, but that cannot
be made the basis or the yardstick for judging the performance of the
professional proceeded against on indictment of negligence.”
65. • In order to protect oneself from malpractice litigation, following points
should be remembered:
Always consider the clinical history viz, history of presenting illness,
past history and occupational and drug history. If more information is
needed, contact the referring physician directly.
Develop good rapport with the patient.
To obtain written informed consent after explaining the risks and
benefits of the imaging procedure. Explain the limitations associated
and available alternatives, if any.
To confirm that the patient is subjected to the test requested and
follow ALARA principle to limit the radiation exposure.
Date and time of the examination should be documented. Regular
check on the computer clocks to be done to avoid out of
synchronization with the actual date and time.
Follow the recommended standard protocols to image the anatomic
structure.
66. To obtain satisfactory image if the initial image quality is not
adequate for interpretation.
Consider additional views if necessary.
Systematically evaluate the images so that the lesions do not go
unnoticed.
Always consider and compare previous imaging study if available.
Do not jump into conclusion or get biased with the previous report.
Document the noted abnormality in the report and reach a
conclusion.
Proofread the report. Correct the typographical errors. This written
report determines whether the radiologic standard of care is
conformed to or breached, once a malpractice lawsuit is filed.
Suggest further appropriate next step to increase diagnostic
specificity, if required.
67. Communicate with the referring physician when important unsuspected finding is
noted that which require immediate management.
While examining female patients, male radiologists should ensure that the
examination is carried out in the presence of female attendant.
When the radiologist feel that he is not expertise in the diagnostic or interventional
procedure requested, consider seeking the help or referral to another colleague.
Radiologists should regularly get updated with the new technologies and current
practice guidelines.
68. CONSENT IN RADIOLOGY PRACTICE
1. Two main indications or instances where consent is necessary in the
daily radiology practice are before
1. administering an intravenous contrast and
2. before performing any interventional procedures.
• Common meaning of consent is permission whereas the law perceives it
as a contract i.e. an agreement enforceable by law.
• In consent, there are four separate but correlated elements that are:
Voluntariness
Capacity
Knowledge and
Decision-making
69. CONSENT IN RADIOLOGY PRACTICE
• It can be either implied or expressed (oral or written).
• Expressed consent includes informed consent, which is the ideal
form of consent because it includes all aspects of meaningful
decision-making.
• Informed consent provides the comprehensive information to
patients on the imaging procedure to be performed which includes
both advantages and potential risks and complications.
• Standard hospital consent forms will not be considered as consent
for diagnostic procedure or therapeutic treatment.
70. TO OBTAIN A LEGALLY VALID CONSENT
Comprehensive consent form should enable balanced judgment by the patient and his/her
relative by explaining the procedure, its risks and benefits, as well as any alternatives if
available.
The signature or thumb impression of the patient must be taken.
In case of legally incompetent patient, the family of the patient becomes the decision
maker. Spouses’ decision is considered the most important, followed by immediate relatives
such as parents, children, and siblings.
No changes can be made in the form thereafter. Such an attempt raises the possibility of
suspicion.
Preserve the document in the departmental records.
71. PRE-CONCEPTION AND PRE-NATAL
DIAGNOSTIC TECHNIQUES ACT (PCPNDT ACT)
• A national law, Pre-natal Diagnostic Techniques (Regulation and Prevention of
Misuse) Act (PNDT Act), 1994 was enacted to prevent sex determination and
came into force on January 1st, 1996.
• In the meantime, new techniques had been developed that used pre-conception
or during conception sex selection. To bring these new technologies under the
purview of the Act, the law was amended in 2003 and is renamed the Pre-
conception and Pre-natal Diagnostic Techniques (Prohibition of Sex Selection) Act
(PCPNDT Act), (effective from February 14, 2003).
• Despite the enactment of the Act in 1996 with subsequent amendment in 2003,
the decline in Child Sex Ratio (CSR) from 927 girls per 1000 boys in 2001 to 914 in
2011 was evident, reflecting the continued practice of sex selection.
• Hence, the Act was again amended in 2012 with steps towards stronger, rigorous
and effective implementation of the Act.
72. PRE-CONCEPTION AND PRE-NATAL
DIAGNOSTIC TECHNIQUES ACT (PCPNDT ACT)
• Why this act?
An Act to provide for the regulation of the use of pre-natal diagnostic
techniques for the purpose of detecting genetic or metabolic
disorders or chromosomal abnormalities or certain congenital
malformations or sex linked disorders and for the prevention of the
misuse of such techniques for the purpose of pre-natal sex
determination leading to female feticide; and, for matters
connected there with or incidental thereto.
This act regulates genetic counseling centers, genetic laboratories
and genetic clinics (used for conducting pre-natal diagnostic
procedures). Use of ultrasound comes under Genetic Clinic.
73. WHO CAN SET UP A GENETIC CLINIC?
• Any person having adequate space and being or employing a Gynecologist having
experience of performing at least 20 procedures in chorionic villi aspirations per
vagina or per abdomen, chorionic villi biopsy, amniocentesis, cordocentesis,
fetoscopy, fetal skin or organ biopsy or fetal blood sampling etc. under supervision
of an experienced
• gynecologist in these fields, or
• a Sonologist, Imaging Specialist, Radiologist or
• Registered Medical Practitioner having post graduate degree or diploma or
• six months training or one year experience in sonography or image scanning, or
• a medical geneticist.
74. GUIDELINES FOR THE USE OF ULTRASOUND IN
GENETIC CLINIC
• Centers where ultrasound is intended to be carried out should get registered, at least 30 days in
advance.
• All ultrasound machines available at that center along with the qualified doctors performing USG
should be registered on the certificate.
• No doctor other than the one registered in the particular centre is allowed to use the machine.
• In the case of a locum doctor, the doctor’s name and personal details, state council registration
number, and his/her degree certificate need to be sent to the appropriate authority (AA)/ward
office, requesting permission for the use of the machine by the locum on the specified dates.
• The USG machine should not be shifted from one Centre to another.
75. • Any changes in the center (e.g., change in machine or place of use) should be
intimated 30 days in advance of the expected date of such change.
• Portable ultrasound machines should be used as a part of the registered mobile
medical unit, offering other health and medical services. It cannot be used in a
vehicle not registered under the Act.
• Registration and practice of sonography by a radiologist/ sonologist is restricted to
two clinics/facilities within a district. The consulting hours by such medical
practitioner should be specified by each clinic/centre.
• Renew the certificate of registration every five years, with application of renewal
being applied 30 days before the date of expiry to the AA.
• A copy of PC-PNDT registration certificate should be displayed in reception area and
the USG room.
76. • A copy of PC-PNDT Act booklet should be made available in both the waiting room and USG
room.
• Sign in English and in the local language must be displayed, indicating that FETAL SEX IS
NOT DISCLOSED IN THE CLINIC.
• Form F must be filled completely. The signed consent of the patient as well as the
radiologist signature who performed the procedure should be obtained. A hard copy with
patient signature has to be preserved at the clinic when form ‘F’ is submitted online.
77. • A monthly report should be submitted to the AA regularly, before the 5th of every
month.
• All the records need to be maintained for a minimum of 2 years. If there is any
legal proceeding pending in court of law, then these records should not be destroyed
till the proceedings have been disposed off.
• Advertisement and communication of sex selection is strictly prohibited under the
act.

Such errors of perception is influenced by multiple factors like faulty reasoning, under reading, inadequate exposure, limitation inherent to the diagnostic test, non communication with the referring clinician, no adequate clinical information available, etc.
Certain psychophysiological factors affecting visual perception like level of observer alertness, workload and fatigue, duration of observer task, distracting factors, conspicuity of abnormality and others also contribute to errors.
