Spectral Doppler mapping of the right branch of the portal vein (RBPV) of one dog. Longitudinal section at approximately the right 10th intercostal space. Note the insonation angle (12 degrees), which provides measurements with minimum margin of error. The flow is monophasic and presents low pulsatility.Back to article page
