MRI对急性胰腺炎诊断及病情程度评估的应用价值

The value of MRI in the diagnosis of acute pancreatitis and the evaluation of the severity of the disease

目的:探讨急性胰腺炎(AP)应用核磁共振成像(MRI)诊断及评估病情程度的价值。方法:将我院收治的疑似急性胰腺炎患者20例作为研究对象,入组对象有完整临床资料,均接受核磁共振成像诊断与检查,将临床综合诊断与术后病理结果作为金标准,评估MRI诊断急性胰腺炎的准确度、敏感度及特异度,同时利用MRI Balthazar评分系统对确诊患者病情程度分级,和临床Ranson评估标准对比,实施统计学分析。结果:20例疑似急性胰腺炎患者经临床综合诊断与术后病理结果明确有16例,MRI诊断敏感度为87.50%(14/16)、准确度为85.00%(17/20)、特异度为75.00%(3/4);确诊为急性胰腺炎16例中轻型10例、重型6例,MRI Balthazar评分系统评估病情程度和Ranson评估标准结果比较差异有统计学意义(P<0.05)。结论:急性胰腺炎患者采取MRI诊断有着不错的价值,而且MRI评估病情程度优于传统Ranson评估标准,值得在临床推广应用。

Objective To explore the value of MRI diagnosis and evaluation of acute pancreatitis(AP). Methods 20 patients with suspected acute pancreatitis as the research object, the set of objects with complete clinical data, we accept MRI diagnosis and examination, the clinical comprehensive diagnosis and postoperative pathologic results as the gold standard,to assess the accuracy of MRI in the diagnosis of acute pancreatitis, sensitive and specific degrees, at the same time using MRI Balthazar scoring system for patients diagnosed the classification, and contrast clinical Ranson assessment standards,implementation of the statistical analysis. Results 20 patients with suspected acute pancreatitis by clinical comprehensive diagnosis and postoperative pathological results in 16 cases, MRI diagnostic sensitivity was 87.50%(14/16), accuracy was85.00%(17/20) and 75.00%(3/4); The results of MRI Balthazar scoring system were statistically significant(P<0.05), and the results of MRI Balthazar scoring system were significantly different from those of the 16 cases of acute pancreatitis.Conclusion MRI diagnosis is of good value in patients with acute pancreatitis, and MRI evaluation is better than traditional Ranson evaluation criteria, which is worthy of clinical application.
