Cirrhosis | Radiology Reference Article | …

Cirrhosis (rare plural: cirrhoses) is the common endpoint of a wide variety of chronic liver disease processes which cause hepatocellular necrosis. Cirrhosis can be diagnosed with ultrasound, CT, and MRI, and these imaging modalities can also be used to evaluate for possible complications of cirrhosis, such as portal hypertension or hepatocellular carcinoma.

HCC is more prevalent in non-Western countries than Western countries. HCC is an infiltrative tumor that may proliferate into the veins. Characteristic of HCC is the marked arterial enhancement and the rapid washout of contrast agent in the portal venous and equilibrium/delayed phases (fig. 10).

Focal Hepatic Lesions: Diagnostic Value of …

Because the main blood supply to dysplastic nodules is from the portal venous system and that to HCC is from the hepatic arterial system (, 19), HCC can often be distinguished from a dysplastic nodule at dynamic gadolinium-enhanced MR imaging on the basis of identification of hepatic arterial phase enhancement (, 20). Dysplastic nodules generally do not enhance during the hepatic arterial phase.

In the portal-venous phase the HCC is hardly distinguishable from the liver parenchyma due to early washout of contrast. This HCC is suitable for mRECIST. iRECIST for immune therapy. iRECIST represents a modified RECIST 1.1 for immune-based therapeutics. The immunotherapeutic agents induce a different tumour response in comparison to standard chemotherapeutic agents. The new …
