Because of the inhomogeneous perfusion in vertebral body
and only enrolled partial volume of vertebral body using
one slice image, it is reasonable to make an assumption
that the bias should be present in DCE-MRI examination.
However, one slice DCE-MRI was usually performed in most
research for temproal resolution. In this study, this
hypothesis that blood perfusion is regional dependent in
vertebral body was demonstrated using three middle
sagittal, middle coronal and whole axial plane in thick
axial slice data. The divergences of peak enhancement,
wash-in and wash-out slope among three planes were
investigated in 70 healthy vertebras.
