摘要
目的探讨16层螺旋CT多种后重组方法在诊断胃间质瘤中的应用价值。方法使用GE-lightspeed 16层螺旋CT机,对经手术、病理证实的胃间质瘤3例充气后行螺旋扫描,并行气体铸形,模拟管腔,立体剖面,仿真内镜及曲面重组,观察其病变特点。结果多层螺旋CT多种后重组方法在诊断胃间质瘤时,能从不同角度显示肿瘤的形态、大小、边缘及与邻近组织、器官的关系,表现为胃体部不规则形肿块,向腔内及腔外突,边界清楚,与周围组织、器官分界清晰。结论多层螺旋CT多种后重组方法对胃间质瘤的定位、定性诊断有很大价值。
Objective To investigate the diagnostic value of 16-MSCT with various post processing techniques in gastric mesenchyme tumor. Method： Three patients with gastric mesenchyme tumor confirmed by operation and pathology received GE Lightspeed16 CT scan after puffed with air. Reformation methods were used. Reformation methods include Gas casting,simulant lumen,solid section,virtual endoscopy and MPCR et al. Results： Gastric mesenchyme tumor was showed in configuration,size,edge,and relationship with adjacent organs after reformed in various technique of MSCT. Conclusion： 16 multislice spiral CT is effective to diagnose gastric mesenchyme tumor in location and the nature by reforming in various post processing technique.
