Abstract OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: To some extent, DSCT can display renal fascia and its superior adherence and reflect the superior communication of the PS. ADVANCES IN KNOWLEDGE: This study was conducted in vivo in adults by high-resolution DSCT, and more samples could be provided. PMID: 25411900 PMCID: PMC4277382 DOI: 10.1259/bjr.20140480
