[Role of 0.5 T magnetic resonance and duplex ultrasonography in the imaging of stenotic and oblitertive changes in the carotid arteries].

The aim of the study was to determine diagnostic value of magnetic resonance angiography (MRA) of the carotid artery, performed with less expensive machine of 0.5 T, and value of duplex ultrasonography (DU) in the same patients. Diagnostic values of MRA and DU were examined by comparison with the results of digital subtraction angiography (DSA) or with the operative finding.
