Doppler Ultrasonographic Estimation of Renal Resistive Index in Horse: Comparison Between Left and Right Kidneys

摘要: Abstract The renal resistive index (RI) is the ratio of difference between maximum and minimum (end diastolic) flow velocity derived from Doppler spectrum intrarenal (segmental/interlobar) arteries. It a good indicator for acute disease, tubular necrosis, obstruction. To our knowledge, no reports are available about values RI in unsedated horses. aim this study was to establish normal reference range (mean ± standard error) assess reliability obtained using transabdominal ultrasonography healthy Thirteen conscious Thoroughbred horses judged based on physical examination, complete blood count, biochemical profile, urinalysis, were included. peak-systolic end-diastolic velocities interlobar arcuate arteries measured. Intrarenal scanned by pulsed calculate RI. comparison left versus right kidneys analyzed with analysis covariance (ANCOVA) procedure. Significant differences (P
