摘　　要：目的探讨胃肠道间质瘤（GIST）的CT表现及在随访中的价值.方法回顾性分析117例经手术病理证实的GIST患者CT资料.结果117例患者共118个间质瘤.发生部位依次为胃56例,小肠40例,食管6例,结直肠6例,肠系膜3例,后腹膜2例,来源不明5例.肿瘤大小1.7～18 cm.＜5 cm者多为圆形或类圆形,密度均匀,增强后均匀强化,＞5 cm者多为不规则分叶状,密度不均,中心可见小片或大片状低密度区,增强后呈不均匀强化.肿块内伴发气体者17例,伴有钙化13例,12例伴有转移.随访37例,23例发生复发和/或肝转移.结论CT检查在GIST诊断及随访中有重要价值.Objective To analyze the value of CT in diagnosing and following - up gastrointestinal stromal tumors （GIST）. Methods 117patients with CT examination and histological diagnosis of GIST were retrospectively reviewed. Results 117 patients had 118 GIST. The locations ofprimary tumorwere as follows ： stomach （n = 56 ） , small intestine （ n = 40 ） , esophagus （n = 6） , colorectum （n = 6 ） , mesentery （n = 3 ） , retroperitoneum （n = 2） and indefinite origin （n = 5）. Size of tumor was 1.7 ～ 18 cm. Tumors （〈 5 cm） mostly appeared round or ovoid shape and homogenous density with uniform enhancement . On the contrary i tumors （〉 5 cm） often demonstrated lobulated shape with central low attenuation area and heterogeneous enhancement. There were 17 tumors with bubble, 13 with scattered calcifications, 12 with metastases of liver. With following - up , 23 of 37 were developed local recurrence or hepatic metastases. Conclusion CT is an effective and useful imaging modality in the diagnosis and follow -up gastrointestinal stromal tumors.
