目的探讨多层螺旋CT下CT仿真胃镜、轴位及三维显像在胃癌术前分期及评估中的诊断价值。方法选取2013—2014年鲁山县人民医院收治的经胃镜活检证实的60例胃癌患者,均行多层螺旋CT扫描后分别行CT仿真胃镜及基于表面透明、遮盖显像的轴位及三维显像检查,将多层螺旋CT结果与手术病理进行比较,计算多层螺旋CT诊断准确率。结果 CT仿真胃镜,轴位及三维显像胃癌原发灶的检出率分别为98.3%,95.0%和95.0%。多层螺旋CT轴位及三维显像评估胃癌术前T,N,M以及TNM临床分期准确率分别是81.7%、78.3%、98.3%和76.7%。结论多层螺旋CT下CT仿真胃镜、轴位及三维显像对胃癌术前分期及评估的诊断效果较为理想,安全性高。
Objective To investigate the diagnostic value of multi-slice spiral CT CT virtual gastroscopy, axial and three-dimensional imaging in the preoperative staging and assessment of gastric cancer. Methods Sixty patients with gastric cancer confirmed by gastroscope biopsy from 2013 to 2014 in Lushan County People’s Hospital were examined with CT virtual gastroscopy and axial transparent imaging based on multi-slice spiral CT and three-dimensional Like inspection, multi-slice spiral CT results and surgical pathology were compared to calculate the diagnostic accuracy of multi-slice spiral CT. Results CT virtual endoscopy, axial and three-dimensional imaging of primary lesions of gastric cancer detection rates were 98.3%, 95.0% and 95.0%. The accuracy of clinical staging of T, N, M and TNM in gastric cancer by multi-slice spiral CT and three-dimensional imaging were 81.7%, 78.3%, 98.3% and 76.7%, respectively. Conclusion CT virtual gastroscopy, axial and three-dimensional imaging with multi-slice spiral CT are more effective and safe for preoperative staging and assessment of gastric cancer.
