摘要目的：研究多层螺旋CT、MRI对胰腺间叶组织来源肿瘤的诊断价值。方法回顾性分析经过临床手术确诊、病理证实的7例胰腺肿瘤CT、MRI的表现，进行诊断总结分析。结果病变分布情况：位于胰腺体部4例，头颈部2例，尾部1例。主要影像特征：CT平扫5例表现为胰腺低密度囊性病灶，2例表现为实性病灶；MRI检查主要表现为胰腺内长T1、长T2异常信号影，及混杂异常信号病灶，病灶边界清晰或不清。后经手术、病理证实胰腺淋巴管瘤2例，脂肪瘤3例，畸胎瘤1例，胰腺淋巴瘤1例。结论多层螺旋CT、MRI平扫及增强扫描联合应用对诊断胰腺少罕见间叶组织来源的肿瘤具有较高的临床应用价值。

abstractsObjective To investigate the diagnostic value of multi-slice CT and MRI on pancre-atic mesenchymal origin tumor. Methods The CT and MRI manifestations of 7 patients with pancreatic tumor confirmed by operation results and pathological results were retrospectively analyzed. Results The location of lesion was:4 cases in the body of the pancreas,2 cases in the head and neck of the pancreas, and 1 case in the pancreas tail. The main image features:5 cases showed low density cystic pancreatic lesions by CT scan,2 cases showed solid lesions by CT scan;MRI manifestation mainly was long T1 and T2 abnormal signal in pancreas,and mixed abnormal signal lesions,clear or unclear boundary of lesions. There were 2 cases of pancreatic lymphangiomas,3 cases of lipoma,1 case of teratoma,and 1 case of pancreatic lymphoma confirmed by pathology after surgery. Conclusions Combined usage of multi-slice spiral CT,MRI scan and enhanced scan,has high clinical value on the diagnosis of pancreatic less rare mesenchymal tissue derived tumors.
