SSEPI diffusion-weighted imaging sequence was implemented in 21 patients with liver lesions, and compared with T2-weighted imaging by 2 independent observers in terms of lesion detection and characterization. A significantly larger number of lesions were detected with DWI when compared with T2 weighted-imaging (overall sensitivity for observer 1/2 was 87.7/81.5% vs. 71.7-69.5%, respectively). In addition, DWI achieved slightly better characterization of malignant lesions. Our early experience shows the potential role of SSEPI sequences implemented in routine liver protocols.
