摘要
目的:运用改良CT严重指数,比较MRI与CECT对诊断急性胰腺炎分级诊断的准确性。材料与方法:2010年2月-2013年3月于我院确诊为AP的患者纳入研究,回顾分析患者临床以及MRI和CECT表现,MCTSI作为MRI严重指数(MRSI)的指标,分别对AP患者作分级诊断与临床评估结果对照。结果:28例患者临床评估为轻型胰腺炎(37.8%),46例患者临床评估为SAP和MSAP(62.2%);MRSI和MCTSI诊断轻型胰腺炎分别为33例(44.6%)和30例(40.5%)。MRSI诊断SAP和MSAP为44例(55.4%);MCTSI诊断SAP和MSAP共41例(59.4%),MRI诊断SAP和MSAP的准确率高于CECT(95.7%对89.1%),差异无统计学意义(P>0.5)。在揭示急性胰腺炎的病因胆管结石和胆囊结石方面MRI优于CT。结论:MRSI和MCTSI评分对急性胰腺炎分级诊断与临床结合Ranson评分分级诊断结果相似;MRI对轻型急性胰腺炎胰腺实质炎症水肿改变的显示优于CECT;MRI对急性胰腺炎严重程度诊断效果与CECT相似,是判断急性胰腺炎严重程度的可靠方法。
Purpose： Using the modified CT severity index, comparison of MRI and CECT on the diagnosis of acute pancreatitis diagnosis accuracy. Materials and Methods： In 2010 February to 2013 March in our hospital were included in the study of AP patients, retrospective analysis of clinical and MRI and CECT, MCTSI as the MRI severity index （MRSI） in- dex, respectively by MRSI and MCTSI in patients with AP diagnosis and clinical assessment results for hierarchical control. Results： 28 cases of patients with clinical evaluation for mild pancreatitis （37.8%）, 46 patients with clinical evaluation for SAP and MSAP （62. 2% ） ; MRSI and MCTSI diagnosis of pancreatitis was 33 cases （44. 6% ） and 30 cases （40. 5% ）. MR- SI diagnosis of SAP and MSAP in 44 cases （55.4%） ; MCTSI diagnosis of SAP and MSAP in 41 cases （59.4%） , the accu- racy of MRI diagnosis of SAP and MSAP was higher than that of CECT （95.7% to 89. 1% ）, no significant difference （ P 〉 0. 5 ）. To reveal the etiology of acute pancreatitis calculus of bile duct and gallbladder stone MRI is superior to CT. Conclu- sion ： MRSI and MCTSI score for the grading and clinical diagnosis of acute pancreatitis with similar diagnosis results of Ran- son grading of MRI on mild acute pancreatitis; pancreatic parenchymal inflammation edema is shown to be superior to CECT; severity diagnostic effects of MRI on acute pancreatitis is similar to CECT, is a reliable method to judge the severity of acute pancreatitis.
