This work evaluates the feasibility of intravoxel
incoherent motion diffusion weighted imaging for
evaluating changes in perfusion of placenta during known
physiologic changes in arterial flow to the uterus in
the supine and left lateral decubitus positions.
Perfusion fraction maps of placenta in the two positions
were compared. Mean perfusion fraction of the placenta
was significantly higher in the left lateral decubitus
position compared with the supine position. Intravoxel
incoherent motion diffusion weighted imaging may be
useful to study placental perfusion in clinical settings
where there is concern of appropriate fetal growth.
