磁共振胰胆管水成像及CT 影像对于胆囊腺肌症的诊断意义

The Diagnostic Value of Magnetic Resonance Cholangiopancreatography and CT Imaging in Gallbladder Adenomyomatosis

目的探索磁共振胰胆管水成像及CT检查技术对胆囊腺肌症的诊断意义。方法选取2018年2月至2024年2月湖北省广水市第一人民医院收治的96例胆囊腺肌症患者为研究对象。根据检查方式的不同,分为磁共振胰胆管水成像检查组(研究组,n=48)和CT检查组(对照组,n=48)。分析胆囊腺肌症的MRCP和CT的表现,并对比两组影像技术诊断准确性。结果在MRCP检查中,胆囊壁可表现出局部或广泛增厚,可见清晰的囊状突起,呈长T1、长T2的信号;在CT检查中,可见胆囊壁明显增厚,但囊状突出显示欠佳。研究组48例胆囊腺肌症患者中,MRCP诊断出46例,诊断准确率达95.83%(46/48);其中,2例误诊为胆囊息肉。对照组48例胆囊腺肌症患者中,CT诊断出35例,诊断准确率为72.91%(35/48);其中,6例误诊为胆囊息肉,4例误诊为胆囊炎,3例漏诊。与对照组相比,观察组诊断准确率显著高于对照组,差异有统计学意义(P=0.002)。结论与CT相比,MRCP技术能显示病灶部位结构更清晰,对胆囊腺肌症具有较高诊断准确性,提高了临床诊断率,减低了漏诊率和误诊率,为临床治疗工作提供了更可靠的依据。

Objective To explore the diagnostic significance of magnetic resonance cholangiopancreatography(MRCP)and CT imaging techniques in gallbladder adenomyomatosis.Methods 96 patients with gallbladder adenomyomatosis admitted to the First People's Hospital of Guangshui City,Hubei Province from February 2018 to February 2024 were selected as the study subjects.According to the different examination methods,they were divided into the MRCP examination group(study group,n=48)and the CT examination group(control group,n=48).The effectof MRCP and CT on gallbladder adenomyomatosis were analyzed,and the diagnostic accuracy of the two imaging techniques was compared.Results In MRCP examination,the gallbladder wall could show local or diffuse thickening,clear cystic protrusions,and long T1 and T2 signals;in CT examination,the gallbladder wall was significantly thickened,but the cystic protrusions were poorly displayed.Among the 48 patients with gallbladder adenomyomatosis in the study group,46 cases were diagnosed by MRCP,with a diagnostic accuracy of 95.83%(46/48);among them,2 cases were misdiagnosed as gallbladder polyps.In the control group of 48 patients with gallbladder adenomyomatosis,35 cases were diagnosed by CT,with a diagnostic accuracy of 72.91%(35/48);among them,6 cases were misdiagnosed as gallbladder polyps,4 cases were misdiagnosed as gallbladder inflammation,and 3 cases were misdiagnosed.Compared with the control group,the diagnostic accuracy of the observation group was significantly higher than that of the control group(P=0.002),with statistical significance.Conclusion Compared with CT,MRCP technique can display the lesion site structure more clearly,with higher diagnostic accuracy for gallbladder adenomyomatosis,improving the clinical diagnosis rate,reducing misdiagnosis and missed diagnosis rates,and providing a more reliable basis for clinical treatment.
