Detection of Small Hepatic Lesions: Superparamagnetic Oxide-Enhanced Diffusion-Weighted T2 FSE Imaging

The liver is a common site for metastases from colorectal carcinoma and other neoplasms. Most colorectal carcinoma deaths are attributable to hepatic metastases, and the number of these metastases is increasing (Ballantyne and Quin, 1993). The prognosis of patients without treatment is dismal because most cases die within a few years after discovering the liver lesion. Hepatic resection is the sole treatment that regularly leads to longterm survival with a possible chance of cure in patients with hepatic metastases, especially those of colorectal origin. With techniques such as intraoperative ultrasonography (Makuuchi et al., 1991), which improves the management of perioperative patients, hepatic resection has extended the possibility of liver surgery in patients with advanced metastatic tumors (Kawasaki et al., 1994). Also, hepatic resection has been proved to improve the prognosis of patients (Penna and Nordlinger, 2002). Therefore, accurately detecting small lesions is indispensable in preoperative imaging assessment when planning hepatic resection.
