摘要:
目的 评价低管电压、低对比剂浓度及低造影剂流速条件下行冠状动脉、肺动脉、主动脉全段及分支一站式CT血管成像的图像质量和辐射有效剂量的应用价值。方法 回顾性分析不同浓度造影剂下完成一站式血管扫描的60例患者，按不同的扫描条件和造影剂浓度分为A、B两组，每组30例。A组：管电压80 kV，管电流250 mA，碘浓度300 mg/mL，流速3.5 mL/s；B组：管电压100 kV，管电流200 mA ，碘浓度320 mg/mL，流速5 mL/s 。将两组图像质量进行客观评价，比较两组图像的血管（冠状动脉、肺动脉、主动脉全段主干分支）CT值、对比度噪声比（CNR）、图像噪声（PN）和辐射有效剂量。结果 两组图像质量主客观评价A组与B组冠状动脉各主干CT值及其PN（PN1），肺动脉主干、左右肺动脉CT值及其PN（PN2），主动脉各处CT值差异均有统计学意义（P＜0.05）；冠状动脉CNR（CNR1）、肺动脉CNR（CNR2）、主动脉PN（PN3）、主动脉CNR（CNR3）无统计学差异（P＞0.05）。A、B两组血管计算机体层摄影血管造影辐射有效剂量分别为（3.7±0.7）mSv、（6.8±0.9）mSv，A组辐射有效剂量较B组降低约45.6%。结论 采用低管电压结合低对比剂浓度及低造影剂流速行体部大血管一站式扫描时，图像质量在主观评价上满足诊断要求，在客观评价上与常规扫描方法测得结果基本一致，不仅降低患者碘摄入量，还降低约45.6%的辐射有效剂量。
Abstract:
Objective To evaluate the image quality and radiation doses of one-stop CT angiography of coronary artery,pulmonary artery and aorta under the low tube voltage,low contrast agent concentration and low flow rate of contrast medium . Methods A retrospective analysis was performed on 60 patients who completed one-stop vascular scanning under the same flow rate of contrast agent. According to different scanning conditions and contrast agent concentration s,they were divided into two groups equally. Group A:the tube voltage was 80 kV,the tube current was 250 mA,the iodine concentration was 300 mg/mL,and the flow rate was 3.5 mL/s. Group B:the tube voltage was 100 kV,the tube current was 200 mA,the iodine concentration was 320 mg/mL and the flow rate was 5 mL/s. The image quality of each group was objectively evaluated. The CT values,contrast noise ratio(CNR),image noise(PN) and radiation dose of the images of blood vessels were compared,including the coronary artery,pulmonary artery and main branch of the whole section of aorta. Results The image quality of the two groups was evaluated objectively and subjectively. There were statistically differences in CT values of each main coronary artery and picture noise( PN1),pulmonary artery and left & right pulmonary arteries and picture noise( PN2),CT values of the aorta(P＜0.05),and there were no significant differences in coronary artery contrast noise ratio(CNR1),pulmonary artery contrast noise ratio(CNR2),aortic picture noise ratio( PN3) and aortic contrast noise ratio(CNR3)(P＞0.05). The effective radiation doses of computer tomography angiography (CTA) in two groups were (3.7±0.7) mSv and (6.8±0.9) mSv respectively. The effective radiation dose of group A was about 45.6% lower than that of group B. Conclusion When using one-stop CT scan as low tube voltage combined with low contrast agent concentration and low contrast agent flow rate to line the large blood vessels in the body,the image quality meets the diagnostic requirements in subjective evaluation,and the objective evaluation is basically consistent with the results measured by conventional scanning methods,which not only reduces the patient’s iodine intake,but also reduces the effective dose of radiation by about 45.6%
