摘　　要：目的分析低剂量CT头颈血管成像与高场磁共振血管成像(MRA)对头颈部动脉狭窄的诊断价值。方法45例头颈部动脉狭窄患者,均进行低剂量CT头颈血管成像检查和高场MRA检查。比较两种检查方法的诊断结果及图像质量。结果高场MRA的诊断敏感度90.00%、特异度96.00%、阳性预测值94.74%及阴性预测值92.31%与低剂量CT头颈血管成像的80.00%、88.00%、84.21%、84.62%比较,差异均无统计学意义(P>0.05)。高场MRA图像优良率93.33%显著高于低剂量CT头颈血管成像的75.56%,差异有统计学意义(P<0.05)。结论高场MRA诊断头颈部动脉狭窄具有图像质量高的优势,可作为首选诊断方法,但低剂量CT头颈血管成像技术同样具有良好的敏感度与特异度,在头颈部动脉狭窄的临床诊断中,低剂量CT头颈血管成像与高场MRA各有其优势与不足,为进一步提高诊断准确率,必要时可联合应用。Objective To analyze the value of low-dose CT head and neck angiography and high-field magnetic resonance angiography(MRA)in the diagnosis of head and neck artery stenosis.Methods Low-dose CT head and neck angiography and high-field MRA were performed in 45 patients with head and neck artery stenosis.The diagnostic results and image quality of the two methods were compared.Results The diagnostic sensitivity,specificity,positive predictive value and negative predictive value of high-field MRA were 90.00%,96.00%,94.74%and 92.31%,which were 80.00%,88.00%,84.21%,and 84.62%of low-dose CT head and neck angiography,and the difference were not statistically significant(P>0.05).The rate of high image quality of highfield MRA was 93.33%,which was significantly higher than 75.56%of low-dose CT head and neck angiography,and the difference was statistically significant(P<0.05).Conclusion High-field MRA has the advantage of high image quality in the diagnosis of head and neck artery stenosis and can be used as the preferred diagnostic method.However,low-dose CT head and neck angiography also has good sensitivity and specificity.In the clinical diagnosis of head and neck artery stenosis,both low-dose CT head and neck angiography and high-field MRA have their own advantages and disadvantages.If necessary,it can be used in combination.
