摘要:
目的 对比分析下肢骨肉瘤的X线与MRI表现,探讨MRI对骨肉瘤的诊断价值。方法 收集经手术或病理穿刺活检证实的下肢骨肉瘤15例,男11例,女4例,均行MRI平扫及增强扫描(4例行CT扫描),并摄有X线平片,对其MRI征象与X线征象作逐一对比。结果 MRI及X线平片对下肢骨肉瘤的诊断准确率均为100%,MRI在显示病变范围、放射状骨针、Codman三角两层结构以及跳跃病灶等方面明显优于X线平片检查。结论 X线平片是诊断骨肉瘤最简便而实用的方法,但MRI可以更好的显示病变的范围,发现早期病变。
Abstract:
Objective To investigate the diagnostic value of magnetic resonance imaging (MRI) for lower limb osteosarcoma by comparing the findings between X-ray and MRI. Methods Fifteen surgically or pathologically confirmed patients with lower limb osteosarcoma (11 males and 4 females) underwent both plain and enhanced MRI (with CT scanning in 4 cases) in addition to radiography, and the findings were compared. Results The diagnostic accuracy of both MRI and X-ray film was 100%. Compared with X-ray, MRI was capable of clear display of the lesion extent, perpendicular periosteal reaction, the two layers of Codman’s triangle and the skip lesions. Conclusion Plain X-ray film provides a convenient and practical diagnostic modality for lower limb osteosarcoma, but MRI has better performance in clearer display of the tumor range and identification of early-stage lesions.
