Dynamic contrast‐enhanced magnetic resonance imaging (DCE‐MRI) has been shown to be a promising technique for assessing lung lesions. However, DCE‐MRI often suffers from motion artifacts and insufficient imaging speed. Therefore, highly accelerated free‐breathing DCE‐MRI is of clinical interest for lung exams.
