【摘要】：目的探讨多排螺旋CT对胃平滑肌瘤与胃神经鞘瘤的鉴别诊断价值。方法回顾性分析我院经手术病理及免疫组化证实,CT资料完整的22例胃平滑肌瘤及16例胃神经鞘瘤,采用两样本t检验分析瘤体的长径、长短径之比数据、静脉期CT值并绘制ROC曲线得到最佳诊断值。采用Fisher’s确切概率法分析发病部位、生长方式、形态、粘膜强化、钙化、强化程度。结果与胃神经鞘瘤相比,胃平滑肌瘤好发于贲门,多向腔内生长,增强扫描轻度强化,长径≤3.2cm,长径/短径1.2,静脉期CT值65HU(P0.05)。用长径≤3.2cm、长径/短径1.2、静脉期CT值≤63HU作为标准,敏感度依次为86.4%、81.82%、95.24%,特异度依次为62.5%、81.25%、56.24%。结论使用以上特异的CT标准鉴别胃平滑肌瘤与胃神经鞘瘤有很高的准确性。
[Abstract]:Objective to evaluate the value of multi-slice spiral CT in differential diagnosis of gastric myoma and gastric schwannoma. Methods 22 cases of gastric smooth myoma and 16 cases of gastric schwannoma confirmed by operation, pathology and immunohistochemistry in our hospital were analyzed retrospectively. the long diameter, the ratio of length to short diameter, the CT value of venous phase and the best diagnostic value of ROC curve were analyzed by two sample t test. Fisher's exact probability method was used to analyze the location, growth mode, morphology, mucous membrane enhancement, calcification and enhancement degree of the disease. Results compared with gastric schwannoma, gastric myoma was more common in cardia, multidirectional intracavitary growth, slightly enhanced scan, long diameter 鈮，
