摘要
目的:探讨标准化头颈联合CTA检查在头颈动脉狭窄中的应用价值。方法:应用64层螺旋CT,对拟诊颅、颈动脉疾病的35例患者进行头颈联合CTA检查,均以九位法及自动旋转法来显示动脉的位置,对两种方法显示头颈动脉狭窄的能力进行对比分析。以常规DSA检查作为标准,评价CTA诊断头颈血管性病变的敏感性、特异性及准确性。结果:图像质量评分分别为2.81±0.32和2.83±0.36。九分法与自动旋转法对头颈动脉的显示差异有统计学意义(P<0.05)。头颈联合CTA总体诊断的敏感性、特异性及准确性分别为83.1%、99.4%、97.5%。结论:智能触发增强扫描技术结合头颈动脉九位法显示,不受个体差异影响,可以实施标准化头颈联合CTA检查,对头颈动脉狭窄的诊断及手术方案的制订具有很高的临床应用价值。
Purpose： To discuss the value of the standardization of examination protocol of Multiple- Mice CTA in intracranial and cervical arteries for evaluation of artery stenosis. Methods： Thirty-five patients （28 males and 7 females, 33-75 years old, mean age 56.8 years） were examined with MSCT angiography by using the CARE bolus-triggered technique. The images were reconstructed by maximum intensity projection （MIP） and volume rendering （VR）, and were displayed by nine-position method and automatic rotation method to evaluate the three-dimensional reconstruction imaging quality. The ability for demonstration of intracranial and cervical arteries was compared between that by automatic rotation method and nine-position method. Taking the results of DSA as the reference, the sensitivity, specificity, and accuracy of CTA for imaging the intracranial and cervical lesions were evaluated. Results： According to the standard evaluation of imaging quality, the vascular image quality scors were （2.81±0.32） and （2.83±0.36） respectively. The significant differences were detected for demonstration of intracranial and cervical arteries between that by automatic rotation method and nine-position method （P〈0.05）. Over all sensitivity, specificity and accuracy of CTA were 83.1%, 99.4% and 97.5%, respectively. Conclusion： The standardized examination of CTA may be served as an important rob in diagnosis and treatment of stenosis in intracranial and cervical arteries.
