Popliteal artery entrapment: MR findings.

A 35-year-old woman with a history of claudication was examined by means of echodoppler, angiography, and MR imaging using gradient rephased sequences, performed at rest and during stress. Magnetic resonance imaging allowed the evaluation of the relationships between the gastrocnemius muscle and the popliteal artery at rest and the evidence of the occlusion during stress. This combined morphological and functional evaluation makes MR a procedure of choice for assessment of young adults with intermittent claudication.
