- •
Effective dose is 10–20 mSv for coronary CTA and myocardial rest- and stress imaging.
- •
Modifying the phantoms in accordance with clinical practice had a noticeable effect.
- •
k-factors may lead to underestimations of effective dose by a factor of 2–3.
- •
Effective dose in cardiac CT is relatively high for females.
