Although surgical resection offers a better curative option than nonsurgical treatments, it is not an option for the majority of patients with poor hepatic function or at an advanced stage when diagnosed.Transcatheter arterial chemoembolization (TACE) is an alternative and effective nonsurgical treatment for HCC. Evaluation of the effect of TACE is important to develop a best therapeutic strategy. From January 2009 to December 2010, 28 patients with HCC received TACE at the PLA General Hospital, and the results of magnetic resonance imaging ( MRI) were analyzed. Fifty-one lesions were detected and the maximum diameter of the lesions was 14.7 cm. Twenty-eight lesions in 16 patients which showed variable signal intensity on T1- and T2 -weighted images and iso- or hypointensity on diffusion-weighted image ( DWI) had no enhancement.
