Abstract

Purpose: We evaluated the utility of iopamidol-based nonionic contrast media ($Pamiray^{(R)}370$) for cardiac CT, with assessment of its image quality and safety. Materials and Methods: The study included 100 patients who underwent cardiac CT with $Pamiray^{(R)}370$ (experimental group), and 100 patientswho underwent cardiac CT with $Ultravist^{(R)}370$ (control group). A comparison of the image qualities and degree of vascular contrast enhancement was made between the two groups and evaluated statistically by an independent t-test. Changes in vital signs and adverse events during cardiac CT were evaluated in the experimental group. Results: There were no statistically significant differences in the image quality (image quality score in experimental group vs. control group: 4.26 ${\pm}$ 0.63 vs. 4.24 ${\pm}$ 0.62), and mean attenuation values at the coronary arteries(p > 0.05) between two groups. For the experimental group, 12% experienced adverse events, including mild and transient reactions such as dizziness (7%), nausea (4%), and fatigue (1%). Further, 94% of patients complained of mild to moderate febrile sense just after contrast agent administration, which spontaneously disappeared within 3 minutes without any specific management. Conclusion: For cardiac CT, $Pamiray^{(R)}370$ was comparable to the widely-used contrast agent ($Ultravist^{(R)}370$) in terms of image quality and safety without any severe adverse reaction.

목적: 심장 CT에서 iopamidol 조영제인 $Pamiray^{(R)}370$의 유용성을 영상의 질과 안전성에 기인하여 평가하고자 하였다. 대상과 방법: 최근 4개월 동안 $Pamiray^{(R)}370$을 사용하여 심장 CT를 시행 받은 환자 100명을 시험군으로, 그리고 기존에 심장 CT에 사용된 $Ultravist^{(R)}370$을 사용하여 심장 CT를 시행 받은 100명의 환자를 대조군으로 하였다. 두 군 사이에 영상의 질과 관상동맥 각 분지의 조영증강 정도를 independent t-test를 이용하여 비교 평가하였다. 또한, 시험군에서 심장 CT 동안의 자작증상과 부작용 유무를 평가하였다. 결과: 시험군과 대조군에서 영상의 질 평가점수는 각각 4.26 ${\pm}$ 0.63점, 4.24 ${\pm}$ 0.62으로 통계적으로 유의한 차이를 보이지 않았으며(p > 0.05), 관상동맥 각 분지의 조영증강 정도 역시 각각 408 ${\pm}$ 38~447 ${\pm}$ 56과 412 ${\pm}$ 26 ~444 ${\pm}$ 37로 통계적으로 유의한 차이를 보이지 않았다(p > 0.05). 시험군의 12%에서 조영제 주입 후 어지러움(7%), 구역(4%), 근무력감(1%) 등 경도의 부작용을 보였으나 자연 소실되었다. 자각 증상으로는 94%에서 순간적인 발열감을 보인 후 자연 소실되었으며, 그 외 심각한 부작용은 없었다. 결론: 심장 CT에서 iopamidol 조영제인 $Pamiray^{(R)}370$은 기존에 사용되던 iopromide 조영제($Ultravist^{(R)}370$)와 비교하여 영상의 질 및 관상동맥 조영증강 정도에 있어 유의한 차이가 없고, 또한 임상적으로 심각한 이상 징후를 발생시키지 않아 향후 심장 CT에 유의하게 사용될 수 있는 경정맥 조영제로 생각된다.
