![]() Sometimes called "wash out phase" or "equilibrium phase". Only in this phase you will be able to detect small renal cell carcinomas. This is when all of the renal parenchyma including the medulla enhances. In this phase the liver parenchyma enhances through bloodsupply by the portal vein and you should see already some enhancement of the hepatic veins. Although hepatic phase is the most accurate term, most people use the term "late portal phase". Hepatic or late portal phase - 70-80 sec p.i.All structures that get their bloodsupply from the arteries will show optimal enhancement. Sometimes also called "arterial phase" or "early venous portal phase", because some enhancement of the portal vein can be seen. This is the phase when the contrast is still in the arteries and has not enhanced the organs and other soft tissues. Non-enhanced CT (NECT) Helpful in detecting calcifications, fat in tumors, fat-stranding as seen in inflammation like appendicitis, diverticulitis, omental infarction etc.Scroll through the images to see the enhancement in the different phases. So it is important to know in which phase a CT should be performed depending on the pathology that you are looking for. Sometimes a lesion will be hypovascular compared to the normal tissue and in some cases a lesion will be hypervascular to the surrounding tissue in a certain phase of enhancement. The purpose of contrast-enhanced CT (CECT) is to find pathology by enhancing the contrast between a lesion and the normal surrounding structures.

All of these complications were diagnosed with intravenous contrast-enhanced MDCT, except one, which required a barium transit study. We reviewed 155 cases and found 24 complications in 22 patients: 16 early complications (7 intraperitoneal hematomas, 5 anastomotic dehiscences, 2 intestinal obstructions, and 2 external hernias) and 8 late complications (3 internal hernias, 3 intestinal perforations, and 2 marginal ulcers). We classified complications into early complications (appearing within 30 days of the intervention) and late complications. ![]() We retrospectively studied all patients who underwent gastric bypass or sleeve gastrectomy at our center during 2013 or 2014. To review the complications of bariatric surgery and their diagnosis with intravenous contrast-enhanced multidetector computed tomography (MDCT). Deben reconocerse los hallazgos normales en estos pacientes para identificar rápidamente las posibles complicaciones, diagnosticadas en su mayoría mediante TCMDcCIV. La tasa de complicaciones en la cirugía bariátrica es elevada y su mortalidad no es despreciable. Todas las complicaciones se diagnosticaron mediante TCMDcCIV, excepto una que requirió un tránsito baritado. Se revisaron 155 casos y se diagnosticaron 24 complicaciones en 22 pacientes: 16 precoces (7 hematomas intraperitoneales, 5 dehiscencias anastomóticas, 2 obstrucciones intestinales y 2 hernias externas) y 8 tardías (3 hernias internas, 3 perforaciones intestinales y 2 úlceras en boca anastomótica). Las complicaciones se dividieron en precoces (durante el primer mes) y tardías. Material y métodosĮstudio retrospectivo de los pacientes intervenidos mediante by-pass gástrico o gastrectomía tubular en nuestro centro durante 2013 y 2014.
