摘　　要：目的评价MSCT动态增强及图像后处理技术在胃肠肿瘤术前的临床应用价值。方法对资料完整的31例胃肠肿瘤的CT图像进行回顾性分析。结果胃肠道出现不同程度增厚24例,增厚程度超过3cm的10例,三期动态增强均明显强化;肠腔狭窄12例,其中2例出现肠梗阻;呈软组织肿块突入腔内或腔内外4例,均匀中等度强化;形成肿块的2例,呈不均匀强化;病变周围浸润呈脂肪密度增厚,筋膜影增厚22例;淋巴结转移14例;远处脏器转移4例。结论MSCT多期动态增强,结合图像后处理技术,可准确评价肿瘤的可切除性、周围侵犯程度、血供走行、腹膜播散及远处脏器转移情况,对于以手术切除为治疗方案的胃肠道肿瘤,术前影像学评估的临床应用价值较高。Objective To evaluate the clinical application value of MSCT dynamic enhancement and image postprocessing in the preoperative treatment of gastrointestinal tumors.Methods CT images of 31 cases of gastrointestinal tumors with complete data were retrospectively analyzed.Results There were 24 cases with different degree of gastrointestinal thickening,and 10 cases with thickening degree exceeding 3cm.Intestinal stenosis occurred in 12 cases,of which 2 cases had intestinal obstruction.There were 4 cases with soft tissue mass protruding into or out of the lumen,uniform and moderate enhancement.2 cases of mass formation showed uneven enhancement;Fat density thickened and fascia shadow thickened in 22 cases.Lymph node metastasis in 14 cases;Distant organ metastasis occurred in 4 cases.Conclusion Multi-stage dynamic enhancement of MSCT,combined with image post-processing technology,can accurately evaluate tumor resectability,peripheral invasion,blood supply progression,peritoneal dissemination and distant organ metastasis.Preoperative imaging evaluation has high clinical application value for gastrointestinal tumors treated by surgical resection.
