Figure 3. Contribution of CCS and CCTA to total radiation exposure using prospective versus retrospective CCTA protocols.

Figure 3

With retrospective CCTA, CCS contributed to only 6–9% of the total radiation exposure. Conversely, with prospective scans, CCS contributed to 40–50% of the total radiation exposure, when low-tube voltage and BMI-adapted imaging parameters were applied.
