超声造影与MRI对胰腺囊性病变的诊断价值比较

Diagnostic Values of Contrast-Enhanced Ultrasound and MRI in Pancreatic Cystic Lesions

目的探讨超声造影(CEUS)与核磁共振成像(MRI)对胰腺囊性病变的诊断价值。方法回顾性分析我院收治的90例胰腺囊性病变患者临床资料,所有患者均行CEUS、MRI及病理学活检。分析CEUS与MRI下胰腺囊性病变的影像特点,以病理学活检结果为"金标准",分析两种影像学检查方法鉴别诊断胰腺囊性病变肿瘤性的准确度差异。结果各类胰腺囊性病变在CEUS及MRI中影像特点均有所不同,两种检查方法对其鉴别诊断准确率分别为74.4%(67/90)与78.9%(71/90),相互比较无统计学意义(P>0.05)。结论 CEUS与MRI鉴别诊断胰腺囊性病变均可获得较为理想的准确度,临床应用价值均较高。

Objective To explore the diagnostic values of contrast-enhanced ultrasound（CEUS） and magnetic resonance imaging（MRI） in diagnosis of pancreatic cystic lesions. Methods The clinical data of 90 patients with pancreatic cystic lesions admitted to our hospital were analyzed retrospectively. All patients were given CEUS, MRI and pathological biopsy. The imaging features of pancreatic cystic lesions under CEUS and MRI were analyzed, and the pathological biopsy results were taken as ＂gold standard＂, and the accuracies of two imaging methods were analyzed in differential diagnosis of pancreatic cystic lesions. Results The imaging features of various types of pancreatic cystic lesions were different in CEUS and MRI, and the diagnostic accuracies were 74.4%（67/90） and 78.9%（71/90） respectively in two methods（P〉0.05）. Conclusion CEUS and MRI both can obtain ideal accuracy in differential diagnosis of pancreatic cystic lesions, and both have high clinical application values.
