摘要
目的 探讨能谱CT在头颅CTA应用时的最低造影剂剂量.方法 3组患者均因病情所需接受头颅CTA检查但注射不同剂量造影剂,其中A组30 mL、B组40 mL、C组50 mL.结果 A组图像优良率最低(23.33%),B组、C组图像优良率较高(分别为93.33%、96.67%),数据比较差异具有统计学意义(P>0.05);C组各项造影剂相关不良反应发生率最高(P<0.05),A组、B组造影剂相关不良反应发生情况对比差异无统计学意义.结论 应用头颅CTA检查过程中以40 mL碘离子造影剂注射剂量有效性、安全性均较理想.
Abstract
Objective To investigate the minimum dose of contrast medium when using spectral CT in cranial CTA. Methods Three groups of patients were required to undergo head CTA examination because of their condition,but different doses of contrast agents were injected.Among them,group 30 mL, group B, group 40mL, group C and group 50 mL were A. Results In group A,the lowest rate of excellent image (23.33%), B group, C group had higher rate of excellent image (93.33%, 96.67%), comparison of the data P<0.05; C group the highest rate of adverse reaction of contrast agent (P<0.05),data comparison P<0.05, A group, B group significantly adverse reactions of contrast agent there is no difference between the situation (P>0.05). Conclusion The use of 40 mL iodide contrast medium in the procedure of cranial CTA examination is effective and safe.
