What safety principle should guide CT imaging in ACS workup?

The safety principle guiding CT imaging in ACS workup is to apply ALARA—keep radiation exposure as Low As Reasonably Achievable—while still obtaining the necessary diagnostic information. This means using dose-optimized CT protocols, such as ECG-gating and lower radiation settings, limiting the scanned area to what’s essential, and employing advanced image-reduction techniques, all while considering shielding when appropriate. Because ionizing radiation can affect a developing fetus, screening for pregnancy in women of childbearing age is essential; if pregnancy is possible, alternatives or timing adjustments should be used to avoid fetal exposure unless the CT result is urgently necessary. High-dose contrast and universal avoidance decisions aren’t the safety core here—contrast carries its own risks, and CT isn’t categorically ruled out in ACS when benefits outweigh risks.
