Ultrafast non-ECG-gated cardiac spectral CT scanning for myocardial late iodine enhancement assessment: a feasibility study

Ultrafast non-ECG-gated cardiac Spectral CT provides high-quality images for evaluating LIE, 76% reduction of radiation dose, 50% increase in signal-to-noise ratio, and 91% reduction of acquisition time. ECV measurements demonstrate high interobserver reproducibility. Preliminary findings show good agreement with CMR; while based on a limited validation cohort with selective ECV use.
