【摘要】 目的探讨1.5T磁共振水成像在胃肠道疾病的临床诊断价值。方法经手术或临床证实的胃肠道疾病患者4 5例,依检查部位和目的不同,用不同方法将水引入胃肠道。先行常规MRI扫描,再行2D HASTE序列水成像扫描。结果 45例均获得较为满意的图像。病变处正常粘膜破坏消失26例,管腔狭窄29例,扩张13例,龛影12例,充盈缺损27例。定位诊断准确率为100%(45/45),定性诊断准确率为88.9%(40/45);与常规MRI结合,定性诊断准确率可提高到93.3%(42/45)。结论磁共振水成像能显示胃肠道疾病的部位和大体形态特征,与常规MRI结合,能提高其定位、定性诊断准确率,磁共振胃肠道水成像(MRGIH)是常规MRI的重要补充。更多还原

【Abstract】 Objective To explore the clinical value of 1.5T magnetic resonance gastrointestinal hydrography(MRGIH) in the diagnosis of gastrointestinal diseases. Methods Fortyfive patients with gastrointestinal diseases confirmed with pathology or clinical findings were examed. Water was induced into gastrointestinal tract with different methods according to different sites or purposes. A 2D HASTE sequence was used to acquire MRGIH images in addition to routine MRI. Results All forty-five cases acquired good MRGIH images. No normal folds could be seen in the lesion in 26, lumen stricture in 29, lumen dilatation in 13, crater in 12, filling defect in 27. The accuracy of the correct location and the correct diagnosis with MRGIH was 100%(45/45) and 88.9%(40/45) respectively. When MRGIH was combined with MRI images, the accuracy of the correct diagnosis was increased to 93.3%(42/45). Conclusion MRGIH can demonstrate the position and the characteristics of the lesions. Combined with MRI images, it can increase the accuracy of the correct location and the correct diagnoses. So, MRGIH is an important complement to routine MRI images.更多还原
