Role of Triphasic Helical CT and Recent MRI Techniques in Diagnosis of Hepatocellular Carcinoma
Mohammed Ghonamy M. Abdalla;
Abstract
On a worldwide basis, primary liver cell carcinoma is one of the commonest malignant neoplasms.
Most hepatocellular carcinoma (HCC) arises in patients with chronic liver disease, usually cirrhosis that especially due to HBV & HCV infection. The fibrotic and nodular parenchymal changes seen with cirrhosis make radiological evaluation of the cirrhotic liver difficult because there can be overlap in the spectrum of imaging findings of benign changes
related to cirrhosis and HCC.
Recent developments m imaging techniques, particularly CT scan and MR imaging, enable the radiologist to evaluate accurately a wide variety of focal and diffuse hepatic pathologies.
In the initial evaluation of a patient with HCC, CT is the most accurate modality for detecting extrahepatic abdominal, retroperitoneal, or chest metastases.
Tri-phasic helical CT using a large-dose bolus injection of contrast material is one of the primary methods of diagnosing hepatocellular carcinoma. Arterial phase images are better than the portal venous and delayed phase images in the detection of most hepatocellular cas;cinoma. Some hypovascular carcinoma are only visualized on the portal venous.
