摘　　要：【目的】探讨MRITzwI联合三维容积内插快速扰相GRE（VIBE序列）动态增强序列在前列腺癌诊断与鉴别诊断中的价值。【方法】收集并分析经过手术、穿刺后病理或经临床治疗后证实的2l例前列腺癌患者的资料，所有患者均在常规扫描的基础上进行三维容积内插快速扰相GRE序列动态增强扫描。【结果】常规MRITzwI检查确诊率为47．6％（10／21），TzwI联合VIBE动态增强序列检查确诊率为71．4％（15／21），前列腺癌病灶的动态增强表现为早期出现强化，迅速达到峰值，强化幅度大，增强中晚期时间强化曲线多数为流出型，少数为平台型。【结论IT。wI联合VIBE动态增强序列检出率高，值得临床推广应用。[Objective] To explore the value of MRI T2WI combined with three-dimension dynamic con- trast-enhanced（DCE） volume interpolated body examination（VIBE） in the diagnosis and differential diagnosis of prostate cancer. [Methods]Clinical data of 21 patients with prostate cancer confirmed by surgery, pathology after puncture or clinical therapy were collected and analyzed. MRI T2WI combined with DCE-VIBE was per- formed on all patients based on conventional scanning. [Results]The diagnosis rate of conventional MRI T2 WI was 47.6%（10/21, while the diagnosis rate of T2WI combined with DCE-VIBE was 71. 4~ （15/21）. DCE manifestations of prostate cancer were early intensification, which was up to the peak rapidly and had high ex- tent. Most time intensity curve in middle-late period of intensification was outflow type, and the minority was plateau type. [Conclusion] Tz WI combined with DCE-VIBE has higher detection rate, so it is worthy of clini- cal promotion.
