Noninvasive physiologic vascular studies play an important role in the diagnosis
and characterization in peripheral arterial disease (PAD) of the lower extremity.
These studies evaluate the physiologic parameters of blood flow through segmental
arterial pressures, Doppler waveforms, and pulse volume recordings. Collectively,
they comprise a powerful toolset for defining the functionality of the arterial
system, localizing the site of disease, and providing prognostic data. This
technology has been widely adopted by diverse medical specialty practitioners,
including radiologists, surgeons, cardiologists, and primary care providers. The
use of these studies increased substantially between 2000 and 2010. Although they
do not employ imaging, they remain a critical component for a comprehensive
radiologic vascular laboratory. A strong presence of radiology in the diagnosis
of PAD adds value in that radiologists have shifted to noninvasive alternatives
to diagnostic catheter angiography (DCA), such as computed tomography (CT) and
magnetic resonance (MR) angiography, which provide a more efficient,
less-expensive, and lower-risk alternative. Other specialties have increased the
use of DCA during the same period. The authors provide a review of the relevant
anatomy and physiology of PAD as well as the associated clinical implications. In
addition, guidelines for interpreting the ankle-brachial index, segmental
pressures, Doppler waveforms, and pulse volume recordings are reviewed as well as
potential limitations of these studies. Noninvasive physiologic vascular studies
are provided here for review with associated correlating angiographic, CT, and/or
MR findings covering the segmental distribution of PAD as well as select
nonatherosclerotic diagnoses. ©RSNA, 2016.
