摘　　要：目的:探讨CT和磁共振(MRI)在胃肠间质瘤(GIST)术前可切除性评估中的应用价值。方法:回顾性分析2010年1月至2016年5月广西医科大学第一附属医院收治的74例GIST患者的临床资料,均接受CT、MRI检查和手术病理检查。应用MedCalc软件对影像资料进行受试者工作特征(ROC)曲线分析,比较在GIST术前可切除性评估中CT和MRI检查的准确性。结果:74例患者均进行手术治疗,其中47例作根治性切除,14例作姑息性手术,13例肿瘤无法切除行病理活检。ROC曲线分析显示,CT的ROC曲线下面积(AUC)为0.903,MRI的AUC为0.959,MRI的AUC高于CT。结论:MRI在GIST术前评估中较CT具有更高的准确性。Objective： To investigate the value of CT and MRI for preoperative assessment of tumor resectability in patients with gastrointestinal stromal tumors （GIST）. Methods： A retrospective study was carried out in 74 patients with GIST. All cases received CT, MRI and pathological examinations. The accuracy of CT and MRI in the evaluation of tumor resectability was compared by receiver operating characteristic （ROC） curve analysis using MedCalc software. Results. 74 patients received surgical treatment, with 47 radical resection and 14 palliative resection. The tumors from 13 cases could not be resected and conducted pathological biopsy. ROC analysis showed the AUC of CT was 0. 903 and MRI was 0. 959 （P〈0.05）. Conclusion： MRI had higher accuracy than CT in the preoperative evaluation of tumor resectability in GIST patients.
