正常人与早期颈髓损伤患者MRI表观弥散系数的比较
|
摘要
目的比较正常人与早期颈髓损伤患者表观弥散系数(ADC)的变化。方法对18例早期颈损患者和5例健康对照者进行MRI T1WI、T2WI和弥散加权成像(DWI)检查,获得颈髓不同平面的ADC值和ADC图。结果和结论早期颈髓患者的ADC值低于健康人,两者分界点为800.0×10-6mm2/s;部分MRI检查无明显异常信号的患者ADC值也下降。
Objective To compare the apparent diffusion coefficients(ADC) between healthy people and patients with early cervical spinal cord injury(SCI). Methods 18 patients with early cervical SCI and 5 healthy controls were examined with MRI T1 WI, T2 WI and DWI,and the ADC values and ADC maps were obtained. Results and Conclusion ADC values were less in the patients than in the healthy controls, and the cut-off point was 800.0×10-6mm2/s. ADC values also reduced in some patients without obvious abnormal MRI finds.
