摘要
背景：CT尤其是增强CT（CECT）是判断急性胰腺炎严重程度和预后的重要方法，然而近年MRI有取代CT的趋势。目的：比较MRI与CECT诊断重症急性胰腺炎（SAP）的准确性。方法：2006年1月-2008年9月于泰州市人民医院确诊为SAP的住院患者纳入研究。回顾性分析人选患者的临床以及MRI和CECT表现，以Bahhazar分级系统评估MRI严重指数（MRSI）和CT严重指数（CTSI）。结果：共36例患者临床评估为SAP，入院2d内和第7d的MRSI与C偈I无明显差异。MRI诊断SAP的准确率高于CECT（94．4％对83.3％），但差异无统计学意义（P〉0．05）。结论：MRI用于SAP的诊断，效果与CECT相似且禁忌证相对较少，是判断急性胰腺炎严重程度的可靠方法。
Background： CT, especially the contrast-enhanced CT （CECT） can provide important information on the degree of severity and prognosis of acute pancreatitis （AP）. However, MRI has a trend of replacing CT in the diagnosis and assessment of AP. Aims： To compare the accuracy of MRI and CECT in the diagnosis of severe acute pancreatitis （SAP）. Methods： Inpatients diagnosed as having SAP in Taizhou People＇s Hospital from Jan. 2006 to Sep. 2008 were recruited and analyzed retrospectively, mainly on their clinical, MRI and CECT findings. Balthazar＇s grading system was used for the assessment of MRI and CT severity indices （MRSI and CTSI, respectively）. Results： Among the 36 patients diagnosed as SAP clinically, no significant differences were observed between MRSI and CTSI on day of admission and the 7th day after admission. The accuracy rate of MRI in diagnosing SAP was higher than CECT （94.4% vs. 83.3%, P〉0.05）. Conclusions： In the diagnosis of SAP, the efficacy of MRI is similar to that of CECT, but contraindications were less. MRI can be used as a reliable method for assessing the degree of severity of AP.
