摘　　要：目的　分析血精性精囊炎的MRI表现 ,探讨MRI在血精性精囊炎诊断中的价值。方法　回顾性分析了 2 5例血精性精囊炎的MRI表现 ,观察其形态、大小及内部异常信号改变 ,分别采用SET1WI(TR/TE 5 5 8/14ms) ,Flash 2D水激励T1WI(TR/TE18 5 /5 2ms) ,TSET2 WI(TR/TE 40 0 0 /99ms)加脂肪抑制序列扫描。结果　本组 2 5例血精性精囊炎均表现为两侧精囊体积增大 ;精囊内“出血”于SET1WI呈斑片状 /斑点状高信号 ,此高信号影于Flash 2D水激励T1WI序列显示更清晰 ,低信号精囊管道壁因高信号出血衬托而得以显示 ;精囊内“出血”于TSET2 WI呈相对较低信号 ,低信号精囊管道壁被较低信号出血影掩盖而显示不清。结论　MRI能对血精性精囊炎做出明确诊断 ,是血精性精囊炎最可靠的影像学检查方法。Objective To analyze the MRI characteristics of hematospermia seminal vesiculitis(HSV) and evaluate the diagnostic value of MRI in HSV. Methods The MRI parameters of 25 HSV patients underwent magnetic resonance imaging(MRI) imaging with SE T 1WI(TR/TE 558/14ms), Flash 2D water excitement(TR/TE 18.5/5.2ms), TSE T 2WI(TR/TE 4000/99ms) and fat suppression sequences were retrospectively analyzed. Results The bilateral seminal vesicles in all 25 patients with HSV enlarged. On SE T1-weighted images, intraseminal vesicle hemorrhage appeared as high signal intensity, which appeared more bright on Flash 2D water excitement sequence. The hypointensive duct wall of seminal vesicles could be clearly seen because of hyperintensive hemorrhage. On TSE T2-weighted images, intraseminal vesicle hemorrhage appeared as relatively lower signal intensity, and the duct wall of seminal vesicles could not clearly be depicted for being covered with relatively hypointensive hemorrhage. Conclusion Hematospermia seminal vesiculitis could be identified by MRI, and MRI was the best imaging method for examining hematospermia seminal vesiculitis.
