摘要
目的 比较CT与MRI诊断胆系结石疾病的临床价值。资料与方法 对 2 8例胆系结石患者进行CT与MRI检查 ,并与临床诊断或手术结果对照 ,其中胆囊结石 11例 ,胆管结石 8例 ,胆囊结石合并胆管结石 9例。CT采用常规 1次屏气螺旋扫描 ,MRI采用FLASH、HASTE、TRUEFISP序列及磁共振胰胆管造影 (MRCP)成像技术。结果2 8例中 ,CT检查明确诊断结石 16例 (准确性为 5 7.1% ) ,MRI检查明确诊断 2 7例 (准确性为 96 .4 % )。结论 CT与MRI对胆系结石均有较好的诊断价值 ,但MRI具有成像参数多、可多平面观察及可特殊成像 (MRCP)等特点 ,对胆系结石的诊断明显优于CT。
Objective To evaluate MRI and CT in the diagnosis of cholelithiasis.Materials and Methods CT and MRI findings in 28 patients with pathologically proved cholelithiasis, including cholecystolithiasis (n=11), cholangiocholithiasis (n=8) and cholecystolithiasis with cholangiocholithiasis (n=9), were retrospectively analyzed, and the CT signs were compared with the pathological results. Routine spiral CT scanning with single breath hold was performed in all patients. For MRI, FLASH, HASTE, TRUEFISP sequences and MRCP technique were adopted. Results Of 28 cases, CT identified the diagnosis of cholelithiasis in 16 (accuracy 57.1%), while MRI identified cholelithiasis in 27 (accuracy 96.4%).Conclusion CT and MRI are very helpful for the diagnosis of cholelithiasis. MRI is superior to CT in diagnosing cholelithiasis as MRI can use multiple imaging parameters, be able to show the lesion from multiple planes and make MRCP.
