When symptoms suggestive of peripheral artery<unk>  are present, clinical evaluation along with non invasive testing are enough to establish the diagnosis. Invasive diagnostic studies are anatomic studies that are not used for diagnosis but rather for preoperative evaluation of the anatomy of the vessels. The invasive diagnostic studies, which are basically anatomic studies that rely on imaging, include the following: conventional angiography, CT angiography, MRA and duplex ultrasound.
Peripheral arterial disease MRI
Peripheral arterial disease ultrasound
Peripheral arterial disease CT
Peripheral arterial disease physical examination
Buerger's disease CT scan
Buerger's disease physical examination
Buerger's disease MRI
Varicose veins MRI
