| 目的 分析52例胃肠道间质瘤(GIST)的MSCT表现,评价MSCT对该病的临床应用价值。 方法 收集经手术病理证实的胃肠道间质瘤52例做回顾性分析,部分病例给予MSCT增强扫描。 结果 肿瘤位于胃部23例,小肠18例,大肠5例,肠系膜4例,食管2例。恶性GIST 31例,主要CT表现:肿块直径≥5 cm 27例,29例瘤体内有低密度坏死,肿块边缘分叶状9例。良性21例,肿块直径＜5 cm,边界清晰,密度均匀。CT检查的敏感性为100％,定位准确率为88.5%(46/52),定性准确率为86.5%(45/52)。内生性生长23例,外生性生长18例,内外性生长11例。 结论 CT可作为GIST的常规检查方法,对GIST的准确定位、定性的判断,指导临床治疗和估计预后有重要价值。 |

| Objective To evaluate the diagnostic value of in gastrointestinal stromal tumors by analyzing the MSCT findings. Methods MSCT findings of 52 patients with GIST confirmed by surgery and pathology were retrospectively analyzed, and some of them underwent additional contrast enhanced MSCT. Results All of the 52 patients, 23 lesions were located stomach, 18 in small bowel, 5 in colon, 4 in mesentery and 2 in esophagus incuding 23 endophytic mass, 18 exophytic mass and 11 exo- and endophytic mass were studied. The MSCT findings of malignant GISTs (31 cases) were including: diameter of the mass ≥5 cm (n=27), low density necrosit within the lesions (n=29), lobular in shape (n=9). The benign GISTs (n=21) were less than 5 cm in diameter, with clear configuration and homogenous density. The sensitivity, accuracy for location and quality of MSCT were 100%, 88.5% and 86.5% respectively. Conclusion MSCT is the common and effective modality in diagnosing gastrointestinal stromal tumors. MSCT scan has great diagnostic value in localizing precisely, judging benign and malignantin, guiding clinical therapy and estimating for patients with GIST. |
