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. WebThree basic methods are available: 1) test bolus timing, 2) fluoroscopic triggering, and 3) time-resolved imaging. With test bolus timing a small (1-2 mL) test dose of contrast is first administered. The vessel is often imaged in cross section even if a different primary plane of imaging is used for the MRA itself.
