3. Introduction
⢠A pulmonary ventilation/perfusion scan involves
two nuclear scan test to evaluate
⢠breathing (Lung ventilation).
⢠circulation (Lung perfusion).
⢠They may be done separately or together.
4.
5. Case History
⢠80 years old female patient known case of Hypertenstion (HTN.)
⢠Newly diagnose case of Burketts lymphoma having high pulmonary artery pressure on echocardiogram
⢠(ECHO.)
⢠Indication for perfusion:
⢠Evaluation of
⢠pulmonary embolism (PE), the main cause being deep vein thromboses (DVTs),clots from recent surgery, or trauma.
⢠pulmonary perfusion.
⢠chest pain or shortness of breath (SOB).
⢠Indication for ventilation in conjunction with lung perfusion;
⢠Evaluation of
⢠pulmonary embolism (PE).
⢠chronic obstructive pulmonary disease (COPD)
6. Preparation
⢠A recent (24 hour) chest radiograph.
⢠Rehearse the breathing procedure to assure optimal patient cooperation; instruct the patient to breathe
by mouth.
⢠To assist in distribution to lungs, patient should be asked to cough and take in several deep breaths
before injection
9. Finding
A significantly heterogeneous pattern of tracer distribution is noted in left lung both in perfusion and
ventilation with evidence of multiple non-segmental matched defects and no evidence of segmental
or mismatched.
A matched defects noted in Lt upper lobe.

10. Conclusion
⢠VQ scan have many advantages;
⢠This scan is readily available, with minimal risks involved.
⢠Itâs a relatively good test for blood clots in his-her lungs and current symptoms suggest that you might have a
pulmonary embolism
