In this study, arterial spin-labeling (ASL)-MRI was used to evaluate the vascularity of retained products of conception (RPOCs). In 5 of 7 cases, high signals on ASL-MRI were observed, and therapeutic response could be evaluated by ASL-MRI. However, these findings of ASL-MRI were not completely identical to those of other conventional imaging modalities, such as dynamic contrast-enhanced MRI and Doppler-US. ASL-MRI is clinically feasible and can be used to assess therapeutic response. Although its clinical advantages over conventional imaging need to be evaluated, ASL-MRI has clinical potential for non-invasive assessment of RPOCs.
