Key result
Changes in the velocity blood-pressure index (VBI) measured by ultrasound strongly correlated with pharmacologically induced changes in renovascular resistance (r=0.83, P<0.0001).
Why the study?
Can the velocity blood-pressure index (VBI) measured by ultrasound accurately reflect pharmacologically induced changes in renovascular resistance in healthy volunteers?

PI shows no correlation with RPF or RVR changes; leaves open its utility for noninvasive renal resistance assessment.
Can the velocity blood-pressure index (VBI) measured by ultrasound accurately reflect pharmacologically induced changes in renovascular resistance in healthy volunteers?
Effect estimate: r = 0.83
p-value: p=<0.0001
The velocity blood-pressure index (VBI) derived from ultrasound may serve as a noninvasive tool to assess changes in renovascular resistance.
Bardelli et al. (1992) studied Healthy volunteers (n=6). Velocity blood-pressure index (VBI) measurement was evaluated on Correlation between changes in VBI and changes in renovascular resistance (RVR) (r = 0.83, p=<0.0001). Changes in the velocity blood-pressure index (VBI) measured by ultrasound strongly correlated with pharmacologically induced changes in renovascular resistance (r=0.83, P<0.0001).
