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.

La caracterización de las lesiones congénitas normalmente se realiza mediante tomografía computarizada (TCMD) o resonancia magnética (RM) con contraste endovenoso y reconstrucciones 3D y en diferentes planos. Generalmente se detectan en el periodo prenatal/neonatal o primera infancia sin embargo algunas permanecen asintomáticas y son detectadas incidentalmente en la edad adulta.Įstas malformaciones tienen manifestaciones radiológicas características, aunque pueden simular otras patologías y son causa frecuente de error diagnóstico. Las malformaciones congénitas pulmonares son raras y pueden clasificarse en tres categorías: anomalías broncopulmonares, anomalías vasculares aisladas y anomalías combinadas vasculares y pulmonares.
