To evaluate the clinical performance of simultaneous multi-slice (sms) diffusion-weighted imaging (DWI) of the prostate. A prototype sms-DWI sequence was utilized and compared to conventional DWI sequences. Sms acquisition is based on the recently introduced principle of simultaneously exciting and acquiring multiple slices by a single radiofrequency (RF) pulse, thus accelerating image acquisition directly by the number of simultaneously excited slices (MB-factor). Image analyses revealed similar image quality and lesion detection as compared to conventional DWI sequences at a substantially decreased acquisition time. Sms-DWI seems a valuable alternative to conventional DWI sequences for prostate imaging.
