| Sample population | Effective radiation dose (mSv) | |
| Mean dose reduction (%) | BMI pECG-CCTA rECG-CCTA | |
| Normal weight (18.5–<25) | 1.7±0.2 (range, 1.3–2.2 mSv) | 2.9±0.9 (range, 1.5–4.8 mSv) 41.4 |
| Over weight (25–<30) | 1.7±0.1 (range, 1.6–1.7 mSv) | 3.8±1.7 (range, 1.9–5.9 mSv) 65.3 |
