目的:探讨64排螺旋CT扫描在肠道肿瘤术前诊断中的应用价值。方法:回顾性分析2013年7月至2016年5月期间我院39例肠道肿瘤患者的影像学资料。所有患者采用口服水造影检查技术,运用工作站多平面重建(MPR)方法,获得冠状面、矢状面重建,结合横断面图像,对39例肠道肿瘤患者的螺旋CT表现进行回顾性分析。结果:39例肠道肿瘤中,小肠肿瘤5例,其中腺癌2例、间质瘤2例、淋巴瘤1例;回盲部肿瘤3例均为腺癌;结肠肿瘤22例(包括升结肠11例、横结肠4例、降结肠3例、乙状结肠4例),其中腺癌17例、间质瘤4例、淋巴瘤1例;直肠肿瘤9例均为腺癌。肿瘤并发肠梗阻2例,合并肠套叠1例,肿瘤穿孔1例。肿瘤侵及深肌层28例,突破浆膜层侵犯周围脂肪间隙16例,周围淋巴结转移10例,肝转移1例。结论:64层螺旋CT对胃肠道肿瘤检出率高,能准确判断患者的病变部位和周围侵犯情况,有助于对肿瘤的定性,对术前诊断肠道肿瘤有较高的临床意义。
Objective: To explore the value of 64-slice spiral CT in the preoperative diagnosis of intestinal tumors. Methods: The imaging data of 39 patients with intestinal cancer in our hospital from July 2013 to May 2016 were analyzed retrospectively. All patients underwent oral water contrast imaging technique. The workstation-based multiplanar reconstruction (MPR) method was used to obtain coronal and sagittal reconstruction. The CT findings of 39 patients with intestinal tumors were analyzed retrospectively. Results: Of the 39 intestinal tumors, 5 were intestinal tumors, 2 were adenocarcinoma, 2 were stromal tumors and 1 was lymphomas. 3 were adenocarcinomas of the ileocecal tumor, and 22 were colon tumors (including ascending colon 11 cases, 4 cases of transverse colon, 3 cases of descending colon and 4 cases of sigmoid colon), including 17 cases of adenocarcinoma, 4 cases of stromal tumor and 1 case of lymphoma. All 9 cases of rectal tumor were adenocarcinoma. 2 cases of intestinal obstruction, 1 case of intussusception, 1 case of tumor perforation. Tumor invasion and deep muscle in 28 cases, breaking the serosa invasion of fat around the gap in 16 cases, 10 cases of peripheral lymph node metastasis, liver metastases in 1 case. Conclusion: The detection rate of 64-slice spiral CT in gastrointestinal tumors is high, which can accurately determine the location of the lesion and its surroundings, which is helpful to the qualitative diagnosis of the tumor and has a high clinical significance for the diagnosis of intestinal tumors preoperatively.
