MR angiography of the lower extremity circulation with protocols

Peripheral arterial disease (PAD) is a common problem

worldwide, with an estimated 20 million patients in the US

alone. Although most patients with PAD are asymptomatic,

it is common to present with lower extremity symptoms

such as claudication and sometimes with atypical lower

extremity symptoms. A much smaller percentage of patients

may present with symptoms of critical limb ischemia.
