This study aims to observe whether the renal fascias could be effectively shown by dual-source CT (DSCT) and to explore the superior communication of the perirenal space (PS) in vivo in adults.
275 cases were included in the normal group and 124 cases in the acute pancreatitis group in this study; all images obtained by DSCT were observed; the superior adherence of the renal fascias and the pattern of superior communication of the PS were judged; and the consistency between the two groups was compared.
The superior adherence of the renal fascias was reliably displayed in 57.8% of the normal group and 69.4% of the acute pancreatitis group, the anterior renal fascia (ARF) did not fuse with the posterior renal fascia superiorly. The left ARF fused with the posterior parietal peritoneum in 57.9% of the normal group and 45.3% of the pancreatitis group, where the left PS communicated with the subdiaphragmatic retroperitoneal space (SDRS). The left ARF fused with the peritoneum laterally and simultaneously with the inferior phrenic fascia medially in 42.1% and 54.7% of each group, respectively, where the left PS was open towards the SDRS laterally but sealed off from the SDRS medially. The right ARF fused with the peritoneum in all cases; and the right PS was open towards the bare area of the liver.
To some extent, DSCT can display renal fascia and its superior adherence and reflect the superior communication of the PS.
This study was conducted in vivo in adults by high-resolution DSCT, and more samples could be provided.
本研究旨在观察双源CT（DSCT）能否有效显示肾筋膜，并在成人活体中探索肾周间隙（PS）的上份连通情况。
本研究纳入正常组275例、急性胰腺炎组124例；观察所有DSCT获得的图像；判断肾筋膜的上份附着情况及PS的上份连通模式；比较两组之间的一致性。
正常组57.8%、急性胰腺炎组69.4%的肾筋膜上份附着显示可靠，肾前筋膜（ARF）在上份未与肾后筋膜融合。正常组57.9%、胰腺炎组45.3%的左ARF与后腹膜融合，此处左PS与膈下后腹膜间隙（SDRS）相通。每组分别有42.1%和54.7%的病例中，左ARF外侧与腹膜融合，同时内侧与膈筋膜融合；此处左PS外侧向SDRS开放，但内侧与SDRS隔绝。所有病例中右ARF均与腹膜融合；右PS向肝裸区开放。
DSCT在一定程度上能够显示肾筋膜及其上份附着情况，并反映PS的上份连通情况。
本研究采用高分辨率DSCT在成人活体中进行，可提供更多样本。
