From: MRI in multiple myeloma: a pictorial review of diagnostic and post-treatment findings
A parasagittal dynamic contrast-enhanced MR image is displayed with regions of interest (ROI) drawn in the aorta (red circle), paraspinal muscle (green rectangle), vertebra T10 (yellow polygon) and L3 (blue polygon). ROI-selection in the vertebrae should exclude the entrance of the vertebral vessels and the endplates. This method provides a corresponding time-intensity curve displayed on the right, providing information on tissue vascularization, perfusion, vessel permeability and volume of the interstitial space
