64层螺旋CT对胃肠道间质瘤的定位和定性诊断价值

Clinical value of 64-slice spiral CT in localization and qualitative diagnosis of gastrointestinal stromal tumors

目的探讨64层螺旋cT定位和定性诊断胃肠道间质瘤的临床价值。方法回顾性分析32例经手术和病理证实胃肠道间质瘤患者的临床和CT影像学资料，并进行总结。结果本组发病部位：胃18例，十二指肠2例，空肠5例，回肠4例，腹腔网膜2例。肿瘤直径1．6～16．50cm。多数病灶增强动脉期明显不均匀强化，静脉期呈持续明显强化。18例为潜在恶性或恶性。结论64层CT检查对胃肠间质瘤的定位和定性诊断对临床治疗具有重要指导价值。

Objective To evaluate the manifestation and application value of 64-slice spiral CT in diagnosis of gastrointestinal stromal tumors. Methods CT imaging findings and clinical data of 32 cases with gastrointestinal stromal tumors were retrospectively analyzed. Results In this study,32 cases with gastrointestinal stromal tumors confirmed by surgery and pathology and all patients were undergone plain and enhanced dual-phase scan. Of these patients, 18 cases were located in stomach ,2 cases in duodenum,5 cases in je- junum,4 cases in ileum,and 2 cases in small mesentery. Tumor diameters ranged from 1.6 cm to 16. 50 cm. Most of the lesions showed uneven enhancement in the arterial phase and the tumors were continued to strengthen in venous phase. Eighteen cases were potential malignant or malignant. Conclusion The 64-slice spiral CT exemption is helpful to determine the location and qualitative diagnosis as well as clinical treatment of gastrointestinal stromal tumors.
