Value of multi-slice spiral CT combined with color Doppler ultrasound in the diagnosis of cervical spondylosis of vertebral artery type

Objective To study the clinical value of multi-slice spiral CT combined with color Doppler ultrasound in the diagnosis of cervical spondylosis of vertebral artery type in youth. Methods One hundred patients clinically diagnosed as cervical spondylosis of vertebral artery type were selected as the case group, and 40 healthy people were enrolled as the control group, which were all examined by multi-slice spiral CT and color Doppler ultrasound.The examination results were analyzed statistically. Results(1) Color Doppler ultrasound: the peak systolic velocity(PSV), vertebral artery end diastolic velocity(EDV) in the case group were significantly lower than those in the control group(P0.05); resistance index(RI), pulsatility index(PI) in the case group were significantly higher than those in the control group(P0.05).(2) CT examination: The rates of normal vascular, thinned blood vessels, vascular tortuosity, localized stenosis and occlusion of the lumen in the case group were significantly higher than those in the control group(P0.05). Color Doppler ultrasound showed in the case group the vertebral artery diameter was significantly smaller than that in the control group(P0.05); CT examination showed that vertebral transverse foramen in the case group was significantly less than that of the control group(P0.05). Conclusion Color Doppler ultrasound and multi-slice spiral CT both have their own characteristics in the diagnosis of cervical spondylosis of vertebral artery type in youth. The combination of the two methods can be more comprehensive to make an accurate diagnosis of the disease.
