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.
