OBJECTIVE
This study was performed to investigate the value of computed tomography (CT) in the differentiation of gastric glomus tumors (GGTs) and small gastric stromal tumors (GSTs).
METHODS
Fifty-nine patients with pathologically confirmed GGTs (n = 11) and GSTs (n = 48) from 2006 to 2019 were retrospectively evaluated. All patients' preoperative CT imaging features were analyzed.
RESULTS
The following features were significantly different between GGTs and small GSTs: location in the antrum, endophytic growth, heterogeneous enhancement in the arterial phase, CT value in the arterial phase of ≥60.7 Hounsfield units (HU), CT value in the portal phase of ≥87.6 HU, degree of enhancement in the arterial phase of ≥29.9 HU, and degree of enhancement in the portal phase of ≥49.0 HU. A model including four randomly selected features among these seven criteria was built to differentiate GGTs from small GSTs with a sensitivity and specificity of 90.9% (10/11) and 100% (48/48), respectively.
CONCLUSION
We identified seven features that are useful for differentiating GGTs from small GSTs. A combination of four of these seven criteria may increase the diagnostic accuracy.
目的
本研究旨在探讨计算机断层扫描（CT）在胃血管球瘤（GGT）和小胃间质瘤（GST）鉴别诊断中的价值。
方法
回顾性分析 2006 年至 2019 年间经病理证实的 11 例 GGT 和 48 例 GST 患者的术前 CT 影像学特征。
结果
GGT 与小 GST 之间存在以下特征差异：发生于胃窦部、向腔内生长、动脉期不均匀强化、动脉期 CT 值≥60.7HU、门脉期 CT 值≥87.6HU、动脉期强化程度≥29.9HU、门脉期强化程度≥49.0HU。建立一个包含这七个标准中四个随机选择特征的模型，用于区分 GGT 和小 GST，其敏感性和特异性分别为 90.9%（10/11）和 100%（48/48）。
结论
我们确定了七个有助于区分 GGT 和小 GST 的特征。这七个标准中四个特征的组合可能会提高诊断准确性。
