Twenty consecutive cancer patients with a solitary hepatic metastasis detected with dynamic contrast‐material—enhanced computed tomography (CT) who were considered for hepatic resection underwent magnetic resonance (MR) imaging within 18 days after CT. Histologic confirmation was obtained in all lesions. CT depicted 20 solitary lesions. MR imaging showed a solitary lesion in 14 patients, two lesions in three patients, and more than two lesions in three patients, for a total of 37 lesions. Twenty‐three lesions less than 2 cm in diameter were missed with CT, and six lesions less than 1.3 cm in diameter were missed with MR imaging. MR imaging was superior to CT in the detection of hepatic metastases on a patient‐by‐patient basis (P <.01). The results suggest that MR imaging is superior to dynamic contrast‐enhanced CT for the detection of hepatic metastases.
