目的分析胃间质瘤(GST)SCT征象,评价SCT对GST的诊断价值。方法回顾性分析35例经手术及病理证实的GST临床、病理和SCT资料。结果35例病例中良性8例,交界性7例,恶性20例.SCT平扫呈均匀或不均匀软组织密度,其内可出现坏死、囊变,增强扫描动脉期肿瘤实质呈中度或明显强化,静脉期强化程度高于动脉期。结合手术病理,病变定位准确率为71.4%,判断良恶性准确率为77.1%。结论SCT对GST的定位、定性和指导治疗具有重要的价值。
Objective To analyze the signs of SCT in gastric stromal tumors (GST) and evaluate the diagnostic value of SCT for GST. Methods The clinical, pathological and SCT data of 35 GST patients confirmed by surgery and pathology were retrospectively analyzed. Results The 35 cases were benign in 8 cases, borderline in 7 cases and malignant in 20 cases.SCT showed uniform or inhomogeneous soft tissue density, necrosis, cystic changes and enhanced arterial phase showed moderate or significant enhancement , Venous phase enhanced higher than the arterial phase. Combined with surgical pathology, the accuracy of localization of lesions was 71.4%, and the diagnostic accuracy of benign and malignant tumors was 77.1%. Conclusion SCT plays an important role in the localization, characterization and treatment of GST.
