Key result
Alterations in power Doppler settings, particularly gain and signal power, significantly affected the vascularization index, flow index, and vascularization flow index (P < 0.05).

Do different machine settings affect the quantification of 3D power Doppler vascular indices in an in-vitro flow phantom?
p-value: p=< 0.05
Power Doppler settings significantly alter 3D vascular indices, necessitating standardized settings for reliable intra- and inter-subject comparisons.
Raine‐Fenning et al. (2008) studied this question. Different power Doppler settings and speed of acquisition vs. Other settings was evaluated on Vascularization index (VI), flow index (FI), and vascularization flow index (VFI) (p=< 0.05). Alterations in power Doppler settings, particularly gain and signal power, significantly affected the vascularization index, flow index, and vascularization flow index (P < 0.05).
