| 目的 观察柔性减影CE-boost技术用于头颈部CT血管成像(CTA)的价值。方法 回顾性收集40例接受头颈部CTA检查患者,采用5分制根据整体图像质量、血管清晰度及血管树完整度对常规CTA(A组)及以CE-boost行后处理后所获图像(B组)进行主观评分,以平均CT值、图像噪声、信噪比(SNR)及对比度噪声比(CNR)对2组图像质量进行客观评价。比较2组主观及客观评价结果。结果 B组针对整体图像质量、血管清晰度及血管树完整度的主观评分均高于A组(P均＜0.001);B组颈部及颅内各级动脉平均CT值、SNR及CNR均高于A组(P均＜0.001)。结论 利用柔性减影CE-boost技术可提高头颈部CTA图像质量。 |

| Objective To observe the value of flexible splicing contrast-enhancement boost (CE-boost) technique applicated in head and neck CT angiography (CTA). Methods Data of 40 patients who underwent head and neck CTA examination were retrospectively analyzed. Subjective evaluation of conventional CTA images (group A) and CE-boost images (group B) were performed using a 5-point scale according to overall image quality, vascular clarity and integrity of vascular tree, while objective evaluation of both groups were performed focused on the average CT value, image noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the main vessels. The outcomes of subjective and objective evaluations were compared between groups. Results The subjective scores of images in group B were higher than those in group A in terms of overall image quality, vessel sharpness and integrity of vascular tree (all P＜0.001). The mean CT value, SNR and CNR of vessels at all levels in group B were significantly higher than those in group A (all P＜0.001). Conclusion Flexible splicing CE-boost technique could improve image quality of head and neck CTA. |
