FIGURE 4: Arterial and portal venous phase CT of cholangiocarcinoma. Selected images from a biphasic CT demonstrating early arterial enhancement of a posterior right hepatic lobe mass with mild wash out on delayed phase images in the setting of cirrhosis characteristic of hepatocellular carcinoma.

Transient hepatic 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 resulting from regional variation in the blood supply by the portal vein and/or the hepatic artery .
Selected images from a biphasic CT of Focal Nodular Hyperplasia in the left hepatic lobe (arrow). These masses have characteristic early arterial enhancement (6a) with contrast wash out on the portal venous phase images (6b) from the mass making these lesions difficult to identify on portal venous phase images alone.

The treatment was initially developed in the early 1970s. [1] The several types of hepatic artery treatments are based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70-80 percent of their nutrients and 50% their oxygen supply from the portal vein, and ...
Early systemic arterial phase 15-20 sec: immediately Arteries, without enhancement of organs and other soft tissues. Late systemicarterial phase Sometimes also called "arterial phase" or "early venous portal phase" 35-40 sec: 15-20 sec All structures that get their blood supply from the arteries have optimal enhancement. Some enhancement of the ...
TACE of liver tumors derives its beneficial effect by two primary mechanisms. [3] Most tumors within the liver are supplied by the proper hepatic artery, so arterial embolization preferentially interrupts the tumor's blood supply and stalls growth until neovascularization. Secondly, focused administration of chemotherapy allows for delivery of ...
The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag.
Hepatocellular carcinoma (HCC [1]) is the most common type of primary liver cancer in adults and is currently the most common cause of death in people with cirrhosis. [2] HCC is the third leading cause of cancer-related deaths worldwide.
