胃肠道恶性淋巴瘤的CT/MRI诊断王守安,吴晶涛,陈文新,孙 骏,董 颖(扬州大学临床医学院,江苏省苏北人民医院影像科 江苏 扬州 225001) 【摘 要】 目的 提高胃肠道恶性淋巴瘤的CT/MRI诊断水平。
方法 回顾性分析经手术病理证实的16例胃肠道恶性淋巴瘤的CT/MRI平扫+增强表现。
结果 16例经手术病理证实的淋巴瘤均为非霍杰金淋巴瘤,12例为B细胞来源,3例为小淋巴细胞型,1例为T细胞型。
10例为胃壁肿瘤,5例为小肠肿瘤,1例为结肠肿瘤。
13例表现为弥漫增厚型,3例表现为溃疡型。
增强扫描后15例明显均匀强化,1例不均匀强化。
结论 CT/MRI对胃肠道恶性淋巴瘤具有较高诊断价值。
