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...
PURPOSE: To produce cerebral venograms with thin-section helical computed tomography (CT) and to assess their diagnostic utility. MATERIALS AND METHODS: Thirty-six CT venograms were obtained in 33 patients after intravenous administration of iodinated contrast material. Eighteen patients had suspected du...

We present a case of life-threatening hepatic venous injury in a hemodynamically stable pediatric patient, only detected due to the inadvertent injection of IV contrast into the saphenous vein resulting in a functional CT venogram. This case suggests that CT venogram performed following the standard...
Combining the artery/vein segmentation with the vessel enhanced volume produces an arteriogram and a venogram, which have the potential to extend the diagnostic yield of CTP scans and replace the additional CTA scan, but could also be helpful to radiologists in addition to the CTA scan. 展开 ...
In this patient with persistent bacteremia following thoracotomy for tamponade and veno-arterial extra-corporeal life support (ECLS), FDG-PET/CT showed increase uptake in the right inguinal region where the ECLS cannulas had been situated. Surgical exploration revealed no focus of infection, and ...
2-Deoxy-2-[18F]fluoro-D-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) is an advanced imaging technique that can be used to examine the whole body for an infection focus in a single examination in patients with bloodstream infe
Finally the artery/vein segmentation is used to suppress either the veins or the arteries in the vascular volume to construct the arteriogram and venogram. To evaluate the method, 11 arteriograms and venograms were visually inspected by an expert observer, with special attention to the ...
