骶骨肿瘤的影像学分析

目的:分析骶骨肿瘤的X线平片、CT和MRI影像学表现。方法:回顾性分析经手术后病理证实的65例骶骨肿瘤的各种影像学表现,所有病例均摄X线平片,其中CT检查32例,MRI检查20例,CT和MRI均检查13例。结果:早期骶骨肿瘤X线平片不易诊断,CT、MRI可清楚显示骶骨肿瘤破坏范围、肿瘤与周围组织的关系。结论:骶骨肿瘤的X线平片、CT和MRI影像学资料结合临床表现对骶骨肿瘤的诊断和制订手术方案有重要意义。

Analysis of imaging diagnosis in sacral neoplasms

Objective:To analyze the appearances of X-ray film,CT and MRI in sacral neoplasms.Methods:A retro-spective study of the X-ray,CT and MRI in65patients of sacral neoplasm s proved by surgical pathology.All patients had X-ray film,32patients had CT,20patients had MRI,13patients had both CT and MRI.Results:Sacral neoplasms in the early stage is difficult to make diagnosis by X-ray film.CT and MRI imaging clearly displays the extent of bony destruction,and the relation between tumour and surrounding tissues.Conclusion:X-ray film,CT and MRI combined with clinical situa-tion of sacral neoplasms can be useful in diagnosis of sacral neoplasms,and may be very helpful for surgical planning.
