摘要
目的:探讨螺旋CT各向同性成像在鼻咽癌临床T分期中的价值。方法:对100例鼻咽癌患者进行鼻咽部螺旋CT扫描,将获得的轴位图像和各向同性成像进行对照分析,判断二者对鼻咽癌周围结构浸润和鼻咽癌T分期诊断的差异。结果:各向同性成像与轴位图像对咽旁间隙、蝶骨体、斜坡、卵圆孔、破裂孔等结构受侵的诊断结果比较,差异有统计学意义(P<0.05),对鼻腔、口咽、椎前间隙、翼突/板、岩骨、蝶窦、上颌窦、筛窦、翼腭窝等结构受侵的诊断结果比较,差异无统计学意义(P>0.05);二者对T2、T3分期的诊断结果比较,差异有统计学意义(P<0.05),T1、T4分期结果比较,差异无统计学意义(P>0.05)。结论:螺旋CT各向同性成像有助于提高鼻咽癌临床分期诊断的准确性。
Objective: To investigated the value of nasopharyngeal carcinoma T stage by multi-slice CT system isotropic imaging. Methods: Images of 100 cases nasopharyngeal carcinoma undergoing multi-slice CT examination were analyzed; the images concluded axial images and isotropic imaging. The two sorts of images were studied to find out diversities between nasopharyngeal carcinoma encroaching vicinity and T-stage. Result: From two sort of images, statistically, there was no difference in nasal cavity, oropharynx, retro cardiac space, pterygoid process/plate, os petrosum, sphenoidal sinus, maxillary sinus, ethmoidal sinus and pterygopalatine fossa. There was difference in parapharyngeal space, corpus ossis sphenoidalis, clivus, foramen ovale, foramen lacerum; there was no difference in nasopharyngeal carcinoma T1 stage and T4, but there was significant difference in nasopharyngeal carcinoma T2 stage and T3. Conclusion: Multi-slice CT system isotropic imaging was beneficial to nasopharyngeal carcinoma T stage.
