Abstract： 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25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 SE T1WI(TR/TE 558/14ms),Flash 2D水激励T1WI(TR/TE 18.5/5.2ms),TSE T2WI(TR/TE 4000/99ms)加脂肪抑制序列扫描.结果本组25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SE T1WI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TSE T2WI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.
