Does transcutaneous duplex Doppler ultrasonography accurately measure femoral arterial blood flow compared to a reference transit-time flow method in pigs?
Transcutaneous DDU is a reliable noninvasive technique for measuring femoral artery blood flow in pigs, particularly when tracing the inner envelope of the Doppler spectral dispersion pattern.
Palacio et al. (2003) studied this question.
