AB  - Even a little smaller amount of contract medium is used for cardiac CT according to patient’s BMI,
excellent image with high HU and SNR can be obtained. CT equipment used in this study was light speed
volume CT 64 channel (GE healthcare, USA). Patients with heart rate <65 were classified into 4 groups according
to their BMI and SNR was measured by injecting different amount of contrast media. Collected materials were
analyzed using SPSS 23.0 Ver. at the significance level of p<0.05. By BMI, measured value was the highest at
underweight and the lowest at extreme obese. By contrast media dose, it was the highest at 90 mL and
the lowest at 80 mL. Correlations analysis of variance showed statistically significant difference according to
contrast media dose by BMI. It is considered that contrast medium does should be decided considering BMI
to minimize side effects of contrast medium while acquiring excellent quality SNR.
