1. Applications of 64 slice CT Dr.S Sivasubramanian MD,DNB,FRCR(UK).,

2. Diagnostic Imaging is revolutionized by the arrival of computers and software. Newer technology is still developing due the advancements in software in medical imaging.

4. Applications of 64 slice CT Has created an Imaging Renaissance

6. What is Multislice CT? Also known as – MDCT…

7. ADVANTAGES Reduced scan time( single breathhold imaging possible). Excellent resolution Isotropic resolution in any direction

9. Peripheral Vascular

10. CNS Applications

11. Body Imaging with Isotropic resolution

12. Musculoskeletal

14. Calcium Scoring Function Cardiovascular Coronary CTA 4D Examination

16. Viewing the four major vessels

17. Vessel analysis

18. Stenosis Quantification

19. Plaque differentiation

20. Stent imaging

22. Persistent high triglyceride levels and other high risk factors such as smoking, diabetes, etc.

23. ECG abnormalities on a routine health check-up

25. Moderate to severe hypertension

26. Prior to non-coronary surgery in the adult population, etc

28. ?Coronary ?Aorta ? Pulmonary.

36. Post-processing

37. Sharp delineation ofentire coronary artery tree with isotropic resolution and 0.33 s rotation time MIP VRT

38. Sharp delineation of entire coronary artery tree with 0.33 mm isotropic resolution and 0.33 s rotation time

49. More cost-effective

50. Clear visualization of calcium deposits and plaque morphology

51. Better delineation of stenoses at the origin of the right and left coronary artery

52. True 3D imaging

53. “One-stop shop” analysis—coronary arteries, valves, ventricular analysis, myocardial mass, plaque morphology, lung parenchymaRadiological Society of NA News - August 2005

54. Disadvantages of MDCT ( very few). No direct assessment of flow through the vessels Massive calcifications and stents cause beam hardening artifacts, causing false-positives Need for β-blocking medication when heart rates are elevated No interventions are possible during the examination Radiological Society of NA News - August 2005

55. Vascular

56. Pulmonary

58. Abdominal

69. Aorta

83. PERIPHERAL

85. CNS Applications

86. CTA Subtraction of data CT DSA Non Enhanced CT

91. Perfusion CT For Early Stroke Imaging

92. Musculoskeletal :

96. Very good depiction of Bone Implants and prosthesis

97. Isotropic resolution,Virtual scopy

101. Virtual Endoscopy :

103. Miscellaneous

104. CT Urogram

105. CT- Bone Mineral Densitometry

107. Dental CT

110. Advanced Imaging Better and faster Diagnosis. Better and Early Treatment Better Health
