目的 探讨尿生殖膈MRI影像学的表现特点. 方法 选择4例健康男性尸体盆腔局部离断标本及15名健康男性志愿者,分别进行MRI检查,对照男性盆腔解剖切片与盆腔MRI扫描图像,在MRI图像中找到正常尿生殖膈结构. 结果 解剖标本显示尿生殖膈两侧附于耻骨下支和坐骨支,在前缘和后缘两层结构互相融合.断层切片显示尿生殖膈上筋膜及尿生殖膈下筋膜分别位于最上方和最下方,其间可见会阴深横肌.冠状位MRI影像表现为“三明治”样三层结构,并且可以显示其全程,三层结构显示清晰.15名志愿者采取同样方位及参数的MRI序列进行扫描,图像中尿生殖膈同样呈“三明治”样结构.10例行小视野T2WI及脂肪抑制序列扫描,与常规T2WI序列扫描比较,应用小视野T2WI及脂肪抑制序列可以更清晰地显示尿生殖膈的三层结构. 结论 常规MRI可以显示男性尿生殖膈结构,小视野扫描可以更清晰地显示其结构.
目的 探討尿生殖膈MRI影像學的錶現特點. 方法 選擇4例健康男性尸體盆腔跼部離斷標本及15名健康男性誌願者,分彆進行MRI檢查,對照男性盆腔解剖切片與盆腔MRI掃描圖像,在MRI圖像中找到正常尿生殖膈結構. 結果 解剖標本顯示尿生殖膈兩側附于恥骨下支和坐骨支,在前緣和後緣兩層結構互相融閤.斷層切片顯示尿生殖膈上觔膜及尿生殖膈下觔膜分彆位于最上方和最下方,其間可見會陰深橫肌.冠狀位MRI影像錶現為“三明治”樣三層結構,併且可以顯示其全程,三層結構顯示清晰.15名誌願者採取同樣方位及參數的MRI序列進行掃描,圖像中尿生殖膈同樣呈“三明治”樣結構.10例行小視野T2WI及脂肪抑製序列掃描,與常規T2WI序列掃描比較,應用小視野T2WI及脂肪抑製序列可以更清晰地顯示尿生殖膈的三層結構. 結論 常規MRI可以顯示男性尿生殖膈結構,小視野掃描可以更清晰地顯示其結構.

Objective To investigate the MRI features of male urogenital diaphragm.Methods A total of 4 pelvic specimens of healthy male cadaver and 15 healthy male volunteers underwent pelvic MRI examination.All MRI scan images were analyzed to approach the urogenital diaphragm structure both in corpse and the MRI images.Results The normal urogenital diaphragm of cadavem connected to ramus inferior ossis pubis and ischiadic ramus.There were three layers inside the urogenital diaphragm,including superior fascia of urogenital diaphragm,inferior fascia of urogenital diaphragm and deep transverse muscle of perineum.MRI imaging showed the coronal was the best location to exhibit the urogenital diaphragm,and all of the structure appeared like "sandwich".In the images of the diaphragm of the volunteers also exhibited like "sandwich",and the three layers are moderate signal in MRI.Ten volunteers were given the fat-depresstion and high resolution scan of T2WI in small ROI,and the structure could be seen much clearly.Fat-depresstion and high resolution scan of T2WI in small ROI was the best sequence to exhibit the urogenital diaphragm.Coronal location of the structure appeared like "sandwich".Conclusion MRI is a good way to show urogenital diaphragm,and high resolution scan of T2WI in small ROI can show the structure much clearer.
