The use of helical CT, infusing pump and non-ionic contrast media has enabled the evaluation of different hepatic circulatory phases during contrast injection. Starting the acquisition of scans 20 to 30 seconds after the injection at a rate of 3 to 4 ml/sec the arterial enhancing of the liver is depicted. THROMBOSIS OR COMPRESSION OF THE PORTAL VEIN: Hypervascular triangle-shaped was with peripheral base can be seen, secondary to the increased arterial flow to compensate for the diminished portal flow. ARTERIOPORTAL SHUNTS: This condition can be caused by tumors such hepatocellular adenocarcinomas and hemangiomas, trauma, interventional procedures, cirrhosis, AVMs and surgery. INFLAMMATORY LESIONS: Hypervascular areas can be seen during the arterial phase in abscesses or cholecystitis, returning to their normal condition in the arterial phase. ANATOMIC VARIANTS: Third veins coming from the periphery (capsular veins, accessory cystic vein and an aberrant gastric vein) supply enhanced blood earlier than the portal circulation. OTHER CAUSES: In liver cirrhosis diffuse hyperattenuated areas can be seen during the arterial circulation. In right-sided heart failure, pericardial disease and Budd-Chiari Syndrome, "mosaic areas" can also be noted. In other patients these perfusion disorders were considered unknown. TUMORS: The well-differentiated hepatocellular carcinoma is a lesion with a predominant arterial blood supply, thus appearing in general hyperdense in this phase. Hemangiomas may appear as highly hyperdense lesions in the arterial phase and can be misinterpreted as HCC if smaller than 2 cm. (30% of cases). Focal nodular hyperplasia is a benign lesion (vascular malformation associated with focal nodules of hepatocellular hyperplasia) with increased arterial blood supply. Hepatic adenomas show an important hypervascularity during the arterial phase and, if large, they may present a small central scar and or capsule. Low or high-grade dysplastic nodules can sometimes be seen as hypervascular areas during the arterial phase. Although most metastasis are depicted as hypodense lesions sometimes they can show arterial hypervascularity such as carcinoid and pancreatic islet cell metastasis.

Diseases of the liver and biliary system are common causes of acute abdominal pain and gallstone disease predisposes to cholecystitis and cholangiolithiasis. Sonography is the method of choice for the assessment of cholecystitis, whereas magnetic resonance cholangiopancreaticography (MRCP) is the standard technique to detect stones in the common bile duct. Multi-detector computed tomography (MDCT) is ideal for detection of associated complications, including abscess formation and gall stone ileus. Pyogenic, amebic and fungal liver abscesses are reliably diagnosed with MDCT which can also be used for interventional radiologic therapy of liver abscesses by percutaneous aspiration or drainage procedures. The second most common cause of liver rupture after blunt trauma is spontaneous rupture of hypervascular liver tumors (i.e., HCC, adenoma, angiosarcoma) and due to medical procedures. Multi-phase contrast-enhanced MDCT can reliably detect active bleeding to guide further therapy in these cases.

The current study was designed to investigate the potential association of serum interleukin-10 and interleukin-12 with HCV infection in chronic liver disease and to evaluate their possible role as new biomarkers in HCC development. Material and Methods. Forty-one patients suffering from chronic liver disease (33 patients harbor HCV infection and 8 are HCV-negative patients) were enrolled in the present study and histopathologically diagnosed into 15 patients with HCC, 16 patients with LC, and 10 patients with liver histology compatible with precirrhotic hepatitis (PCH). Ten patients complaining of cholecystitis were included as nondisease control. Serum levels of IL-10 and IL-12 were measured by enzyme linked immunosorbent assay (ELISA). Results. HCV-infected patients showed elevated expression of IL-10 and IL-12 compared to nondisease controls (P < 0.0001) but there is no significant difference with respect to their expression in HCV-negative patients. Serum IL-10 and IL-12 were elevated significantly with disease progression (P < 0.0001) and a positive correlation coefficient was detected between IL-10, IL-12 (r = 0.785, P < 0.0001), and transaminase values suggesting their possible role in chronic inflammation progression leading to HCC. Conclusion. IL-10 and IL-12 might be involved in chronic inflammation progression leading to HCC and their evaluation could be used as new biomarkers to reflect the degree of inflammation in HCC development.
