目的分析讨论胃肠道外间质瘤的影像诊断在临床上的价值。方法选择2013年5月—2015年5月期间本院收治的胃肠道外间质瘤患者共计31例进行研究,所有患者均接受手术治疗且经过临床病理实验室检查确诊,所有患者术前均接受MRI与多层螺旋CT检查,术后对检查结果进行分析讨论。结果经术后病理证实,31例患者胃肠道外间质瘤共计32处(1例患者存在两处病灶),9处位于盆腔、6处位于左肾上腺区、8例位于腹膜后、9例位于腹腔,MRI检查病灶检出31处,检出率为96.88%,7处位于盆腔、5处位于左肾上腺区、9例位于腹膜后、10例位于腹腔,30处诊断为胃肠道外间质瘤,比例为93.75%,1处诊断为恶性肿瘤,无误诊病例;多层螺旋CT检查结果共检出29处病灶,检出率为90.63%,9处位于盆腔、6处位于左肾上腺区、6处位于腹膜后、9处位于腹腔,25处诊断为胃肠道外间质瘤,4处仅诊出为恶性肿瘤,3处误诊,误诊率为9.34%,MRI检出率高于CT。结论 MRI检查可以较为准确筛查出胃肠道外间质瘤,CT检查在肿瘤定位中具有明显优势。
Objective To analyze and discuss the clinical value of imaging diagnosis of extra-gastrointestinal stromal tumors. Methods A total of 31 patients with gastrointestinal stromal tumors admitted to our hospital from May 2013 to May 2015 were enrolled in this study. All patients underwent surgical treatment and were clinically and pathologically confirmed. All patients received preoperative MRI and multi-slice spiral CT examination, postoperative examination results were analyzed and discussed. Results The histopathology confirmed that there were 32 gastrointestinal stromal tumors in 31 patients (1 patient had two lesions), 9 in the pelvis, 6 in the left adrenal area, 8 in the retroperitoneum and 9 in the 31 were detected in the abdominal cavity and MRI examination, the detection rate was 96.88%, 7 in the pelvic cavity, 5 in the left adrenal area, 9 in the retroperitoneum, 10 in the abdominal cavity and 30 in the diagnosis of extraintestinal stromal tumors , A ratio of 93.75%, 1 was diagnosed as malignant tumor, no misdiagnosis; multi-slice spiral CT examination results were detected 29 lesions, the detection rate was 90.63%, 9 in the pelvic, 6 in the left adrenal area, 6 Located in the peritoneum, 9 in the abdominal cavity, 25 were diagnosed as extraintestinal stromal tumors, 4 were diagnosed as malignant tumors, 3 misdiagnosed, misdiagnosis rate was 9.34%, MRI detection rate was higher than CT. Conclusion MRI examination can be more accurate screening of extraintestinal stromal tumors, CT examination has obvious advantages in tumor location.
