WebCurrent CCT systems with 64 detectors provide a typical dose range on the order of 8–20 mSv for coronary angiography. Corresponding doses are 2–6 mSv for invasive angiography, 10–27 mSv for rest–stress nuclear myocardial perfusion imaging studies, and 3.6 mSv from yearly background radiation exposure.

CT Angiography - Types, Indications and Preparation - Medic Journal
WebAn angiogram is a specific type of CT scan with contrast. In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest. For instance, a CT angiogram of the chest to evaluate for PE will have the timing set so the contrast is present in the pulmonary arteries. WebA CTA can also be obtained in the same sitting, requiring an additional 50 mL of contrast. Thus, the 150 mL of contrast that is typical of an enhanced cerebral CT study yields both a high-resolution study of the extracranial and intracranial vessels and a perfusion study of much of the brain. 171. WebWe found a high percentage of vascular abnormalities. A third of these patients had a prior episode of either an aneurysm or CVT. In patients with a history of UIA or CVT performing CTA despite normal CT and LP therefore seems warranted. A prospective study to delineate indications for CTA is needed. chipmunk\u0027s cw
