Patient-Tailored Scan Delay for Multiphase Liver CT ...

2019-9-15 · Portal Venous Phase Images. A greater fraction of portal venous phase scans obtained with patient-tailored scan delay were judged to be optimal (63 of 73 [86%]) compared with those obtained with a fixed scan delay of 80 seconds (51 of 73 [70%], p 0.05). Nine (12.3%) patient-tailored scans were early, and one (1.4%) was very early, compared ...

Using receiver operating characteristic curves to evaluate ...

Arterial phase+portal-venous phase had a smaller AUC (0.84) than arterial phase+delayed phase (0.85), but the difference was insignificant (P=0.15). After combining MSCT enhancement scan with AFP, the AUC, sensitivity, and specificity were 0.95, 94%, and 83%, respectively, indicating a greatly increased diagnostic efficiency for sHCC.

2021-12-7 · 3.2 Arterielle Phase. Nach ca. 20 Sekunden erreicht das Kontrastmittel über die Arteria hepatica die Leber. In dieser Phase werden vor allem Perfusionsstörungen und hypervaskularisierte Tumore sichtbar. 3.3 Portalvenöse Phase. In der portalvenösen Phase wird das Kontrastmittel ca. nach 60 bis 80 Sekunden über die Vena portae angeflutet.

The Radiology Assistant : CT contrast injection and protocols

2014-6-1 · For Late portal venous phase imaging it is different. Here you don't want to be too early, because you want to load the liver with contrast and it takes time for contrast to get from the portal vein into the liver parenchyma. Besides you have more time, because the delayed or equilibrium phase starts at about 3-4 minutes.
