多普勒超声、CT对胰腺黏液性囊性肿瘤的诊断价值对比

Comparison on Diagnostic Value of Doppler Ultrasound and CT for Mucinous Cystic Neoplasm of Pancreas

目的分析彩色多普勒超声、CT对胰腺黏液性囊性肿瘤(MCN)的诊断价值。方法回顾性分析,2017年5月到2019年6月本院收治的49例胰腺囊性肿瘤患者,所有患者均经手术病理检查确诊,28例为MCN者,21例为浆液性囊性肿瘤(SCN)。对患者所得彩色多普勒超声、CT图像进行分析,并对比彩色多普勒超声、CT检查对胰腺囊性肿瘤检出率,以及了解彩色多普勒超声、CT对MCN诊断诊断灵敏性、特异性、准确性。结果MSCT对MCN、SCN检出率分别为92.85%,95.23%,明显高于彩色超声多普勒(71.42%,P<0.05);经彩色多普勒超声检查对MCN的诊断灵敏性、特异性和准确性分别为67.85%、64.26%、71.42%,MSCT检查分别为92.85%、89.28%、96.42%。MSCT明显高于彩色多普勒超声检查(P<0.05)。结论彩多普勒超声、CT均为诊断胰腺MCN的有效手段,但MSCT检查灵敏性、特异性、准确性较高,可为临床术前诊断提供参考。

Objective To analyze the diagnostic value of color Doppler ultrasound and CT for mucinous cystic neoplasm of pancreas(MCN).Methods The clinical data of 49 patients with pancreatic cystic neoplasm admitted to our hospital from May 2017 to June 2019 were retrospectively analyzed.All patients were confirmed by surgical pathological examination.28 patients were MCN and 21 patients were serous cystic neoplasm.(SCN).The color Doppler ultrasound and CT images of patients were analyzed,and the detection rate of pancreatic cystic neoplasm was compared between the color Doppler ultrasound and CT examinations,and the sensitivity,specificity and accuracy of color Doppler ultrasound and CT in the diagnosis of MCN were analyzed.Results The detection rates of MSCT for MSCN and SCN were 92.85%and 95.23%,which were significantly higher than those of color Doppler ultrasound(71.42%)(P<0.05).The diagnostic sensitivity,specificity,and accuracy of color Doppler ultrasound for MCN were 67.85%,64.26%,and 71.42%,and the diagnostic sensitivity,specificity,and accuracy of MSCT examination was 92.85%,89.28%,and 96.42%.The diagnostic sensitivity,specificity,and accuracy of MSCT were significantly higher than those of color Doppler ultrasound(P<0.05).Conclusion Color Doppler ultrasound and CT are both effective methods in diagnosing pancreatic MCN,but the sensitivity,specificity and accuracy of MSCT examination are higher,which can provide reference for clinical preoperative diagnosis.
