摘要:
目的：探讨低管电压联合ASiR-V算法“一站式”心脑血管CTA扫描模式在动脉粥样硬化导致的心脑血管疾病评估中的临床应用价值。方法：回顾性分析需要进行心脑血管疾病筛查扫描的120例患者。依据扫描方式不同，分为3组，每组40人。A组为低剂量一站式”心脑血管CTA扫描模式组（80 kV，管电流智能调控，前置40%ASIR-V，后置50%ASiR-V），B组为常规剂量冠状动脉CTA扫描组（100 kV，550 mA），C组为常规剂量头颈动脉CTA扫描组（100 kV, 500 mA）。对比3组扫描模式的辐射剂量和对比剂用量，同时将3组图像进行主观评价和客观评价。结果：低管电压联合ASiR-V算法“一站式”心脑血管CTA扫描模式有效辐射剂量为（1.36±0.66） mSv，B组的辐射剂量为（2.31±0.75） mSv，C组的辐射剂量为（1.12±0.04） mSv，A组辐射剂量与B组+C组辐射剂量之和差异有统计学意义（P<0.05），A组与B组的LAD近端、LCX近端、RCA近端的CT值差异均无统计学意义（P>0.05），A组与B组的SD、CNR值差异无统计学意义（P>0.05），A组与B组CTA图像质量主观评分差异无统计学意义（P>0.05）；A组与C组的CT值差异均无统计学意义（P>0.05），A组与C组的SD、CNR值差异有统计学意义（P<0.05），A组与C组图像质量主观评分差异无统计学意义（P>0.05）。结论：低剂量“一站式”头颈冠脉血管成像扫描模式的图像质量能满足临床需求，能全面评估动脉粥样硬化导致的心脑血管疾病。
Abstract:
Abstract: Objective To investigate the value of one-stop cardio-cerebrovascular CT angiography (CTA) scanning mode of low-tube voltage combined with ASiR-V algorithm in the evaluation of cardiovascular and cerebrovascular diseases caused by atherosclerosis. Methods A retrospective analysis was conducted on 120 patients who needed screening for cardiovascular and cerebrovascular diseases. According to different scanning methods, the patients were divided into 3 groups, with 40 patients in each group. Low-dose one-stop cardio-cerebrovascular CTA scanning mode (80 kV, automatic milliamperage, 40%ASIR-V preposition, 50%ASIR-V postposition) was adopted in group A, conventional-dose coronary CTA scanning mode (100 kV, 550 mA) in group B, and conventional-dose head and neck CTA scanning mode (100 kV, 500 mA) in group C. The radiation dose and contrast agent dosage were compared among 3 groups of scanning modes, and the obtained images were evaluated subjectively and objectively. Results The effective radiation dose of one-stop cardio-cerebrovascular CTA scanning mode of low tube voltage combined with ASiR-V algorithm was (1.36±0.66) mSv, and the radiation dose was (2.31±0.75) mSv in group B and (1.12±0.04) mSv in group C. The effective radiation dose in group A was significantly lower than the sum of group B and group C (P<0.05). There was no statistical significance between group A and group B in the CT number of LAD proximal end, LCX proximal end and RCA proximal end, SD, CNR, and the subjective score of CTA image quality (P>0.05). The CT number and subjective score of image quality in group A were close to those in group C (P>0.05), but there were significant differences in SD and CNR between group A and group C (P<0.05). Conclusion The low-dose one-stop head and neck coronary angiography scanning mode ensures that the image quality meets the requirements, and it can be used to comprehensively evaluate the cardiovascular and cerebro vascular diseases caused by atherosclerosis.
