MSCT、MRI观察胰腺囊性肿瘤血供情况及病理形态的临床价值

Clinical value of MSCT and MRI in observing blood supply and pathological forms of pancreatic cystic tumors

目的对比多层螺旋CT（MSCT）、核磁共振（MRI）在胰腺囊性肿瘤血供及病理形态诊断中的应用价值。方法回顾性分析经临床病理证实为胰腺囊性肿瘤患者49例的临床资料，均行MSCT和MRI扫描，对比扫描结果。结果MRI诊断胰腺囊性肿瘤的准确率为89．80％显著高于MSCT的73．47％，MRI诊断IPMN的准确性为100．0％，显著高于MSCT的80．0％，差异有统计学意义（P〈0．05）。MSCT对钙化的检出率高于MRI，对中心瘢痕、壁结节或实性成分、囊性成分、与胰腺管相通的检查情况低于MRI，差异有统计学意义（P〈0．05）。结论MSCT与MRI均能够显示胰腺囊性肿瘤的形态和血供情况，但MRI诊断胰腺囊性肿瘤可获得更加丰富的信息。

Objective To compare the application value of multi-slice spiral CT （MSCT） and magnetic resonance imaging （MRI） in the diagnosis of blood supply and pathological forms of pancreatic cystic tumors. Methods The clinical data of 43 patients with pancreatic cystic tumors confirmed by clinical pathology was analyzed retrospectively. All patients underwent MSCT and MRI scan, and the results of scanning were compared. Results The accuracy rate of MRI in the diagnosis of pancreatic cystic tumors was significantly higher than that of MSCT （89.80% vs.73.47%）. The diagnostic accuracy of IPMN was significantly higher than that of MSCT （100.0% vs.80.0%, P〈0.05）. The detection rate of MSCT for calcification was higher than that of MRI, the detection rate of MSCT for central scar, mural nodule or solid components, cystic components and connection with pancreatic duct were lower than those of MRI （P〈0.05）. Conclusion MSCT and MRI can both display the forms and blood supply of pancreatic cystic tumors. However, MRI can obtain more abundant information in the diagnosis of pancreatic cystic tumors.
