摘　　要：目的:根据同层动态CT增强扫描技术而得出3种不同类型的TDC趋势曲线,并探讨其应用于前列腺结节的定性诊断价值。方法:采用同层动态CT增强扫描技术检查9例前列腺结节,把前列腺特异抗原(PSA)升高且已诊断明确的病人分为3组,获得3种不同类型的TDC趋势曲线。在37例前列腺结节患者中前瞻性应用3种不同的TDC趋势曲线分型对前列腺结节进行术前定性评估,并与病理对照。结果:前瞻性检查和定性评估前列腺结节37例,27例经过穿刺或手术病理确诊,25例术前CT诊断与病理诊断一致。结论:前列腺结节3种不同类型的TDC趋势曲线对前列腺结节的诊断准确率高,也可作为B超穿刺的指导,从而提高穿刺的阳性率。To study the diagnostic values of 3 different kinds of TDC trend curves by multi slice CT（MSCT） dynamic scan for prostate nodules. Methods： Nine patients with abnormal PSA level whose diagnosis was confirmed were divid ed into 3 groups and they all underwent MSCT dynamic scan for prostate nodules retrospectively. To refer the article reports, we conclude 3 different kinds of TDC trend curves. Applied 3 different kinds of TDC trend curves in qualitative diagnosis of prostate nodules prospectively, and compared with the results of pathological diagnosis. Result： Thirty seven patients underwent MSCT dynamic scan prospectively, 27 cases of them were certified by biopsy or operations, 25 cases of them were in accord with pathological diagnosis. Conclusion： Application of the 3 different kinds of TDC trend curves could improve the accuracy rate of diagnoses in the prostate nodules. It also provides biopsy under guidance of ultrasound and improves the positive rate.
