评价16排螺旋CT扫描检查对胃肠道间质瘤的诊断价值

To Evaluate the Value of 16 Slice Spiral CT Scan in the Diagnosis of Gastrointestinal Stromal Tumors

目的研究分析16排螺旋CT扫描检查对胃肠道间质瘤(GIST)的诊断价值。方法从2012年1月-2017年1月期间收治的胃肠道间质瘤患者中,选取75例患者作为研究对象,均接受16排螺旋CT扫描检查,由资深的影像科医师阅片,分析16排螺旋CT扫描检查结果。结果以病理学和免疫组织化学检查结果为准,16排螺旋CT检出67例胃肠道间质瘤,诊断符合率为89.33%;术后病理学证实75例患者中,57例良性病变,18例为恶性病变,恶性病变患者发生在肠道、直径>5cm、侵犯周围组织结构、合并淋巴结或脏器转移、病灶边缘模糊比例较良性病变患者更高,差异具有统计学意义(P<0.05)。结论针对胃肠道间质瘤的临床诊断,16排螺旋CT扫描可清楚直观地观察病灶,根据影像学表现鉴别肿瘤的良恶性,对胃肠道间质瘤定位、定性诊断具有重要作用。

Objective To study the value of 16 slice spiral CT scan in the diagnosis of gastrointestinal stromal tumors(GIST). Methods From January 2012 to January 2017 from patients with gastrointestinal stromal tumor, 75 patients were selected as the research object, underwent 16 slice spiral CT scan, by radiologists reading senior, analysis of 16 slice spiral CT scan results. Results Diagnosis coincidence rate was 89.33%; postoperative pathology confirmed 75 cases of patients, 57 cases of benign lesions, 18 cases of malignant lesions, patients with malignant lesions, invasion diameter > 5cm the surrounding tissue structure, with lymph node metastasis, lesion edge or patients with fuzzy proportion is higher in the intestinal tract, benign lesions, the difference was statistically significant(P<0.05). Conclusion According to the clinical diagnosis of gastrointestinal stromal tumors, 16 slice spiral CT scan can clearly observe the lesions, according to the imaging findings of differentiating benign and malignant tumors, plays an important role in the diagnosis of gastrointestinal stromal tumor, location.
