Combined CT arterial portography and CT hepatic angiography for evaluation of the hepatic resection candidate. Work in progress.

摘要: PURPOSE: To determine whether the addition of computed tomographic (CT) angiography to CT arterial portography would improve lesion detection and heighten confidence in interpreting perfusion abnormalities. MATERIALS AND METHODS: The two examinations were performed sequentially 10 candidates for surgical resection hepatic tumors. Arterial vascular access was obtained with bilateral punctures common femoral artery selective placement angiographic catheters superior mesenteric (SMA). scans first during injection contrast material into SMA, followed by repeated imaging liver artery. RESULTS: procedure demonstrated, among other results, three additional lesions patients, a possibly nontumorous abnormality as tumorous one, suspected one. Suspected abnormalities four patients confirmed at angio...
