| 中文摘要: |
| 目的 探讨螺旋CT对胃间质瘤的诊断价值。 方法 回顾性分析经手术病理证实的20例胃间质瘤患者的临床和CT检查资料。 结果 CT平扫均呈单发软组织肿块,其中9例为恶性,肿块较大,最大径均>5.0 cm,密度不均匀,部分有囊变坏死;11例为潜在恶性,瘤体相对较小,最大径均＜5.0 cm,多数密度均匀。2例病变出现钙化。CT增强后肿瘤实质部分均有较明显强化。多平面重建可清晰显示肿瘤与胃的关系。 结论 胃间质瘤的CT表现有一定的特征性,CT扫描+多平面重建有助于定位和定性诊断。 |

| Objective To assess CT diagnostic value of gastric stromal tumor (GST). Methods Clinical data and spiral CT findings of 20 patients with pathologically proven GST were analyzed retrospectively. Results Twenty lesions were solitary in plain CT scan image. The malignant lesions (n=9) were larger than 5.0 cm in diameter and cystic degenerations as well as necrosis were detected within the tumors, while the underlying malignant lesions (n=11) were smaller than 5.0 cm in diameter and most of them showed homogeneous density. Calcification was detected in 2 patients. On enhanced CT scan, the substantial part of the lesions was obviously strengthened. Multiplanar reformation displayed the relationship of tumor and stomach clearly. Conclusion The CT imaging features of gastric stromal tumor are characteristic. Plain CT scan and multiplanar reformation are helpful to determine the location and nature of gastric stromal tumors. |
