单次激发磁共振胰胆管成像与常规磁共振胰胆管造影的比较

摘要

Purpose: To compare single-shot MR cholangiopancreatography (SSMRCP) with ordinary MR cholangiopancreatography (OMRCP)rnand assess the clinical application value of single-shot MR cholangiopancreatography. Materials and Methods: 81 cases with biliary obstructive dis-rneases, 1 case after biliary-jejunum anastcmose operation and 61 cases without obstructive jaundice were examined by OMRCP, SSMRCP ( single slicernand multi slices). The accuracy of the two kinds of technique were compared. Results: OMRCP, single-slice and multi-slices SSMRCP had the samernsensitivity and specificity on showing the site and feature of the diseases, the proximal dilated biliarys and distant normal cholangiopancreatic ducts.rnThe diameter of dilated bile ducts at the same level were compared and 3 methods had no significant difference. On showing the details of the biliaryrndiseases, multi-slices SSMRCP was better. But single-slice SSMRCP was more sensitive on showing pancreatic duct. Conclusion: Ordinary MRCPrncan be replaced by SSMRCP. Compared with the former, the later can achieve the same or even super image quality, and diagnose the bile duct dis-rneases more rapidly. The normal pancreatic duct can be shown better by SSMRCP.%比较单次激发磁共振胰胆管成像(SSMRCP)和常规磁共振胰胆管造影(CMRCP)，评价SSMRCP的临床应用rn价值。材料与方法：81例梗阻性黄疸、1例胆管-空肠吻合术后及61例无黄疸患者行OMRC、SSMRC单层及多层扫描，rn比较两种技术诊断的准确性。结果：三个序列均能显示胆管病变部位、疾病特征、近侧扩张胆管以及远侧正常胰胆管；显rn示扩张胆管直径三个序列间没有显著性差异；SSMRCP多层显示胆管病变细节较好，而SSMRCP单层显示胰管则明显优rn于另两种方法。结论：SSSMRCP可代替OMRCP，准确地、更快速地诊断胆管系统疾病，并能更好地显示正常胰管。
