Synopsis

Image quality and apparent diffusion coefficient (ADC) values of conventional single-shot spin-echo echo-planar imaging (SS-EPI) and prototype small field-of-view EPI (Zoomit_EPI) diffusion-weighted imaging in kidney tumor were compared. Results showed that Zoomit_EPI had better image quality, including fewer distortion artifacts and blurring (p < 0.01), and clearer edges of the lesions. ADC value of Zoomit_EPI had a good correlation with those of SS-EPI (R2 = 0.91), but Zoomit_EPI had significantly larger ADC than SS_EPI with 80.4*10-6 mm2/s.
