【摘要】：目的:比较彩色多普勒超声(color doppler ultrasound CDUS)与磁共振成像(magnetic resonance imaging MRI)在胆道梗阻定位及定性诊断中的应用价值,明确两种检查方法的优势与不足,更好地指导临床对检查方法的选择。方法:本文采用回顾性分析方法。具体如下:(1)收集经手术、病理或内镜逆行胰胆管造影(endoscopic retrograde cholangiopancreatograph ERCP)诊断为胆道梗阻120例患者的临床及影像资料,所有患者均在术前完成CDUS、常规MRI及磁共振胰胆管成像(magnetic resonance cholangiopancreatography MRCP)检查。(2)由两位腹部影像诊断医师对影像资料进行回顾性分析,包括梗阻的部位、程度,病灶特征及周边情况等。(3)分别统计CDUS与MRI在胆道梗阻的定位、定性诊断结果。采用X2检验比较两种检查方法在定位和定性方面的差异。结果:本研究共收集120例胆道梗阻病例,其中CDUS定位准确的有114例,MRI定位准确的有116例,两者定位灵敏度分别为95%、96.6%,差异无统计学意义,P=0.500。在120例病例中CDUS定性准确的有95例,MRI定性准确的有112例,两者定性灵敏度分别为79.2%、93.3%,差异有统计学意义,P=0.000。81例良性病变中,65例CDUS定性准确,MRI定性准确的有74例,两者灵敏度分别为80.2%、91.3%,差异有统计学意义,P=0.022。39例恶性病变中CDUS与MRI定性准确的分别为30例、38例,两者灵敏度分别为76.9%、97.4%,差异有统计学意义,P=0.008。结论:1.CDUS与MRI在胆道梗阻的定位诊断方面具有等效性。2.MRI对胆道梗阻良、恶性病变的鉴别诊断优于CDUS。
[Abstract]:Objective: To compare the color Doppler ultrasound (color Doppler ultrasound CDUS) and magnetic resonance imaging (magnetic resonance imaging MRI) application value in the localization and qualitative diagnosis of biliary obstruction, clear the advantages of the two methods and shortcomings, in order to guide the clinical examination on the choice of methods. Methods: the retrospective analysis method. The details are as follows: (1) collected by surgery, pathology or endoscopic retrograde cholangiopancreatography (endoscopic retrograde Cholangiopancreatograph ERCP) for the diagnosis of biliary obstruction in 120 cases of patients with clinical and imaging data, all patients completed the CDUS before surgery, conventional MRI and magnetic resonance cholangiopancreatography (magnetic resonance cholangiopancreatography MRCP (2)). The imaging data were retrospectively analyzed by two abdominal radiologist, including the site of obstruction, the degree, lesion characteristics and the surrounding circumstances, (3) respectively. CDUS and MRI in the location of biliary obstruction, diagnosis results. X2 test was used to compare the two methods differences in localization and qualitative aspects. Results: This study collected 120 cases of biliary obstruction, of which CDUS accurate positioning of the 114 cases, the accurate positioning of the MRI in 116 cases, both sensitivity respectively. 95%, 96.6%, the difference was not statistically significant, P=0.500. in 120 cases of CDUS identified 95 cases, MRI identified 112 cases, both qualitative sensitivity were 79.2%, 93.3%, the difference was statistically significant, P=0.000.81 cases of benign lesions, 65 cases of CDUS qualitative accuracy, MRI accurately in 74 cases the sensitivity, were 80.2%, 91.3%, the difference was statistically significant, P=0.022.39 cases of malignant lesions in CDUS and MRI identified 30 cases respectively, 38 cases, the sensitivity were 76.9%, 97.4%, a statistically significant difference P=0.008. conclusions: 1 The diagnosis of.CDUS and MRI in the diagnosis of biliary obstruction is equivalent to.2.MRI for biliary obstruction, and the differential diagnosis of malignant lesions is superior to CDUS.
