What is the difference between a CT angiogram and a CT scan with IV contrast? An angiogram is a specific type ofCT scanwith contrast. In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest. What is a CT angiography used f...
The use of angio-CT (automatic table incrementation, dynamic scanning mode, simultaneous intravenous infusion of a large bolus of contrast) has further extended its use for detection of parenchymal necrosis and vascular involvement. CT now plays a central role in diagnosis, prognostication (staging ...
Conclusion The role of angiography in stable patients with pelvic fracture and CT identified contrast extravasation remains questionable. Most of these patients are not in need of angioembolization.doi:10.1007/s00068-021-01628-wJonathan Hammerschlag...
The goal of this study was to determine the diagnostic value of the helical CT without contrast in suspected cases of choledocholithiasis, comparing this test with endoscopic retrograde cholangiopancreatography (ERCP). Forty patients with possible choledocholithiasis were studied prospectively. There ...

Forty-three patients with cerebral vascular malformation were studied with precontrast, immediate contrast, and 1 hr delayed high dose contrast computed tomography (CT) scans. The precontrast scans were abnormal in 81% of patients. The delayed high dose scans demonstrated one angiographically occult,...
