摘要
目的：探讨如何改进螺旋CT三维重建检查技术,以提高腺样体肥大患者成像质量.方法：利用螺旋CT对32例腺样体肥大患者进行检查,通过改进扫描参数、调整成像方向,获得良好的多平面重建图像及三维仿真重建图像.结果：本组腺样体肥大患者全部完成检查, 图像能清楚显示鼻咽部结构的立体影像和病变的部位、大小、形态及其侵犯范围,诊断方法准确可靠.结论：通过改进CT三维重建技术对腺样体肥大患者检查,可取得对临床有价值的三维重建影像.
Objective： Explore how to improve the three--dimensional reconstruction of spiral CT screening technology, to improve image quality in patients with adenoid hypertrophy. Methods： Use of spiral CT in 32 cases of adenoid hypertrophy were examined,By improving the scanning parameters, adjust image orientation, Get a good multi--planar reconstruction and three--dimensional simulation of image reconstruction image. Results： All the adenoid hypertrophy patients were inspected in this group, Images clearly show the structure of three--dimensional imaging of nasopharyngeal and lesion location, size, shape and scope of violations, accurate and reliable diagnostic method. Conclusion：Three--dimensional CT reconstruction through improved patient examination of the adenoid hypertrophy, can be made on the clinical value of three--dimensional reconstruction of images.
