目的 分析经直肠前列腺超声造影时间强度曲线,寻找鉴别外周带结节良恶性的造影量化指标.方法 对47例外周带出现结节、临床疑诊为前列腺癌患者行超声造影检查,分析其时间强度曲线.结果 前列腺癌结节较结节旁腺体有较短的半峰时间(47.1 s±21.1 s vs 74.2 s±29.7 s),其差异有统计学意义(P=0.01);良性结节较结节旁腺体有较低的峰值强度(11.9 dB±7.7 dB vs 17.5 dB±4.5 dB),其差异有统计学意义(P=0.02).结论 通过分析前列腺外周带结节及结节旁腺体的超声造影时间强度曲线中半峰时间、峰值强度参数,以帮助判定外周带结节性质.

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.
