阜外医院吕滨等研究称,做冠脉CT血管造影时,根据体重或体表面积计算造影剂用量效果相似

2020-01-16 朱朱 中国循环杂志

阜外医院放射科吕滨教授等发现,在进行冠脉CT血管造影检查时,根据体重或体表面积决定造影剂用量时,造影剂衰减和图像质量没有明显差别。该研究连续纳入489例疑诊冠心病而进行冠脉CT血管造影检查的患者,按照造影剂计算方法的不同,随机分入体重算法组或体表面积算法组。造影剂的体重算法为个体化碘注射速率。造影剂的体表面积算法为:12 s内按9 600 mg碘/m2给药。结果显示,两组在平均动脉衰减、图像噪声水

阜外医院放射科吕滨教授等发现,在进行冠脉CT血管造影检查时,根据体重或体表面积决定造影剂用量时,造影剂衰减和图像质量没有明显差别。

该研究连续纳入489例疑诊冠心病而进行冠脉CT血管造影检查的患者,按照造影剂计算方法的不同,随机分入体重算法组或体表面积算法组。

造影剂的体重算法为个体化碘注射速率。造影剂的体表面积算法为:12 s内按9 600 mg碘/m2给药。

结果显示,两组在平均动脉衰减、图像噪声水平、信噪比、对比度噪声比或图像质量评分等方面均无显着差别。

体重或体表面积与主动脉衰减不相关。
