[ECG-triggered magnetic resonance tomographic measurement of blood flow velocity in the carotid arteries: comparison with duplex sonography].
Blood flow velocity in the common carotid arteries was measured for 30 vessels by MRI with a multiecho SE-sequence and compared with the results from duplex ultrasound. MR blood flow velocity was measured for a time interval of 390 ms every 30 ms using a EKG-triggered data acquisition. The time-velocity curves measured by MRI and duplex ultrasound were in good agreement. The correlation coefficient for the peak velocity was r = 0.83. Mean peak velocity as measured by MRI was 59 +/- 8% of peak velocity as measured by duplex ultrasound.
