A comprehensive post-processing toolbox for magnetic resonance based peripheral vascular imaging

Peripheral artery disease (PAD) is an important public health concern particularly among the elderly. Although measures such as ankle-brachial index and segmental pressures have been used to characterize disease severity, new magnetic resonance based imaging techniques allow us to assess subclinical vascular function and morphology. Here, we describe...
