Figure 2

Representative DCE-MRI, MRI T2*, and CE-MRA images. Exactly 44 weeks without intervention (control rats) or after 5/6 nephrectomy (CKD rats): (a) DCE images (amplitude A map) of the lateral femoral and tibial subchondral bone marrow of the right knee show significant hypoperfusion in the CKD group (lower) but not in the control group (upper); (b) MRI T2* maps of the lateral femoral and tibial subchondral bone marrow of the right knee show significantly elevated T2* values in the CKD group (lower) but not in the control group (upper); and (c) coronal maximum intensity projections (MIPs) of the CE-MRA images of popliteal arterieheas show a significantly lower signal intensity and smaller vessel diameters in the CKD group (lower). White arrows indicate the popliteal arteries.
