Abstract:
Objective To observe the value of non-parallel transmission(non-PTX)reduced field-of-view(rFOV)echo planar imaging(EPI)sequence applied in diffusion weighted imaging(DWI)for displaying prostate lesions.Methods Conventional EPI-DWI and non-PTX rFOV-EPI-DWI were prospectively acquired in 30 patients with prostate lesions,including 22 cases of prostatic hyperplasia and 8 cases of prostate cancer.Subjective scoring of imaging quality,as well as objective evaluation on indexes including signal-to-noise ratio(SNR),contrast ratio(CR),contrast-to-noise ratio(CNR)and lesions'apparent diffusion coefficient(ADC)values were performed and compared between two kinds of DWI.Results The subjective score of non-PTX rFOV-EPI-DWI was higher than that of conventional EPI-DWI(P＜0.001).SNR,CR,CNR of non-PTX rFOV-EPI-DWI and lesions'ADC values measured on non-PTX rFOV-EPI-DWI were all higher than those of conventional EPI-DWI(all P＜0.05).Conclusion non-PTX rFOV-EPI DWI could display prostate lesions better than conventional EPI-DWI.
