巧用3.0T磁共振实现15 s胰胆管成像

Flexibly Using 3.0 T Magnetic Resonance to Achieve Cholangiopancreatography in 15 s

为探究更适用于临床实践的磁共振胰胆管成像检查方法,以西门子3.0 T磁共振机器为测试设备,以某医院肝胰胆疾病患者35例的磁共振图像为研究对象,对比分析了常规膈肌导航(T2⁃SPACE⁃COR⁃TRIG)、屏气3D⁃SPACE序列20 s和屏气3D⁃SPACE序列15 s的图像质量与测试时间.结果显示:1)3D⁃SPACE序列15 s和膈肌导航得到的图像质量和伪影方面都优于3D序列20 s;2)3D⁃SPACE序列15 s在图像质量和伪影率方面对比膈肌导航的无显著差异(P=0.21),但其检查时间明显较短,检测效率更高.

To explore a more suitable method for clinical practice of magnetic resonance cholangiopancreatography.Siemens 3.0T magnetic resonance machine was used as test equipment.The magnetic resonance images of 35 patients with hepatic,biliary and pancreatic diseases in a hospital were studied.The image quality and test time of conventional diaphragm navigation(T2⁃SPACE⁃COR⁃TRIG),breath holding 3D⁃SPACE sequence(20 s)and breath holding 3D⁃SPACE sequence(15 s)were compared and analyzed.The results showed that:1)The image quality and artifacts of 15 s 3D⁃SPACE sequence and diaphragm navigation were better than those of 20 s 3D sequence,2)There was no significant difference in image quality and artifact rate between 3D⁃SPACE sequence 15 s and diaphragm navigation(P=0.21),but the examination time was significantly shorter and the detection efficiency was higher.
