contrast. Early arterial phase imaging is predominantly utilized for angiography and will be discussed separately. Late arterial phase imaging is almost...

of the circulatory bed during arterial phase and completely enhancement during portal venous phase. During this phase the center of the lesion becomes...

tissue loads radiocontrast during arterial phase, but then returns to a rather hypodense state in venous or later phases. This is a property of for example...

advantageous to have both late arterial and portal venous phase images since some tumors enhance briskly during the arterial phase (hepatocellular carcinoma...

attenuation differences (THAD) are areas of enhancement during the arterial phase of contrast CT of the liver. THAD is thought to be a physiological phenomenon...

to arterial to venous and delay phases). Parathyroid adenoma would show low density on non contrast image, with peak enhancement during the arterial phase...

be hyperattenuating when compared with the surrounding liver. In the arterial phase CT or MRI, there is a strong enhancement not followed by washout. The...

pulsatility on Doppler ultrasound imaging, or hyperintense hepatic arterial phase (HAP) on CT scan with contrast. PVT is also a known complication of...

the liver (also called the arterial phase) rather than when the contrast flows through the veins (also called the venous phase). Sometimes doctors will...

metastases of PNETs are hypervascular and readily visualized in the late arterial phase of the post-contrast CT study. However, morphological imaging alone...

iodine-based contrast agent, both in the late arterial phase and in the portal venous phase (triple-phase study). While MRI is generally superior to CT...

patient is deemed to have pulmonary hypertension if the pulmonary mean arterial pressure is greater than 20mmHg at rest, revised down from a purely arbitrary...

globular/nodular enhancement in the arterial phase, with portions of attenuation of enhancing areas. In the portal venous phase, it shows progressive centripetal...

In medicine, a pulse represents the tactile arterial palpation of the cardiac cycle (heartbeat) by fingertips. The pulse may be palpated in any place that...

CT and MRI, it shows rapid filling during arterial phase, with contrast retention in venous and delayed phases. Most IHs disappear without treatment, leaving...

Transcatheter arterial chemoembolization (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply...
