Abstract:
Objective To evaluate quantitative parameters of contrast-enhanced transrectal ultrasonography for differential diagnosis of prostate nodules in peripheral zone.Methods Forty-seven patients suspected of prostate cancer for peripheral zone nodules on ultrasonographic imaging were enrolled in this study.Time intensity curves of contrast-enhanced ultrasound were analyzed in all patients.Results The full-width at half maximum (FWHM) of malignant lesions in peripheral zone was shorter than that of adjacent peripheral zone (47.1 s±21.1 s vs 74.2 s±29.7 s, P=0.01).The peak intensity (PI) of benign nodules in peripheral zone was lower than that of adjacent peripheral zone 11.9 dB±7.7 dB vs 17.5 dB±4.5 dB, P=0.02).Conclusions It is helpful for differentiation diagnosis of peripheral zone nodule through analyzing FWHM and PI on contrast-enhanced transrectal ultmsonography imaging.
