Direct chest area measurement: A potential anthropometric replacement for BMI to inform cardiac CT dose parameters?
Significant dose reductions for coronary CT angiography (CTA) can be achieved with reduced tube potential (kV); however, the potential effect on image quality is unknown. ⋯ Patients' chest area and BMI classes were frequently discordant, potentially leading to overdosing or underdosing when using BMI to select tube potential.
