Medical Forum / General / Cardiology / July 2006PET Scan vs Angiography
Hi I wanted to know how much is the PET Scan of Coronary Vessels reliable when compared to the Traditional Angiography. Bye Ahmed > Hi > > I wanted to know how much is the PET Scan of Coronary Vessels reliable > when compared to the Traditional Angiography. The PET scan has greater sensitivity and specificity than the lower energy thallium scan. Comparing it to invasive angiography would be like comparing an orange with an apple.

PET gives function perfusion image information while angiography gives anatomical luminal continuity information with limited functional flow information.

Would you translate your reponse into language a non medically trained person can understand?

PET is to angiography as a compass is to a roadmap.

Angiography visualizes the blood vessels feeding the heart and hence can detect a narrowing PET measures the result or endpoint. It is like if you were a manager at a restaurant - if you saw all tables occupied and plates and glasses filled you would conclude the waiter & kitchen was doing its job. On the other hand if some tables had no food or drinks an analysis that tried to find what the bottleneck in the kitchen to the table would be like angiography. Roland HI Can you tell me how much sensitive is PET Scan for the luminal narrowing.Does PET Scan take cross-sections of the coronary vessels.Can radiologists /cardiologists interpret those cross-sections and conclude the percentage of vessel block Ahmed > > Hi > > [quoted text clipped - 12 lines] > Cardiology, Atlanta, Georgia, USA > http://HeartMDPhD.com/TheLife > HI > Can you tell me how much sensitive is PET Scan for the luminal > narrowing.
