Preoperative hepatic imaging for lesion detection with bolus dynamic CT, CT angiography, delayed iodine CT, and MR imaging

This paper determines the value of sequential, multi-modality imaging for preoperative detection of hepatic tumor nodules in candidates for liver resection. Prospectively and preoperatively, we evaluated 26 patients (seven with hepatocellular carcinoma, one with liver cell adenoma, and 18 with metastatic colorectal carcinoma) to determine number and location of tumor nodules. After bolus dynamic CT (BDCT), patients underwent hepatic angiography, CT angiography (CTA), delayed iodine CT scanning (DIS), and MR imaging. Fifty-six tumor nodules were confirmed by surgery and biopsy, 20 patients had hepatic resection
