The pelvic fascia consists of two layers, the parietal and the visceral layers I whose appendages represented by various septa and ligaments subdivide the pelvis in intra- and extraperitoneal spaces. These structures are extremely thin but can be demonstrated thanks to the high-quality images obtained with the latest CT scanners and to the good natural contrast of pelvic fat. To assess the visibility of the anatomic features of these structures, 50 patients with no pelvic conditions which could affect the thickness of the pelvic fasciae and ligaments were examined with CT. The pelvic visceral fascia was clearly demonstrated in 60% of cases, the rectovesical and rectovaginal septa and the medial umbilical ligaments were demonstrated in 100% and 92% of cases, respectively. The umbilico-prevesical fascia and the lateral umbilical ligaments were poorly demonstrated. The depiction of these structures improves the knowledge of pelvic anatomy and yields major pieces of information to better understand several pelvic conditions.
盆筋膜由两层组成，即壁层和脏层，其附属结构以各种隔膜和韧带为代表，将盆腔分为腹膜内和腹膜外间隙。这些结构极其薄，但借助最新CT扫描仪获得的高质量图像以及盆腔脂肪良好的自然对比度得以显示。为评估这些结构解剖特征的可视性，对50例无盆腔疾病（不会影响盆筋膜和韧带厚度）的患者进行了CT检查。60%的病例中盆脏筋膜显示清晰，直肠膀胱和直肠阴道隔以及脐内侧韧带分别在100%和92%的病例中显示清晰。脐膀胱前筋膜和脐外侧韧带显示不佳。这些结构的显示有助于增进对盆腔解剖的了解，并为更好地理解多种盆腔疾病提供重要信息。
