In this in vitro study performed at 9.4T, the internal
magnetic field gradient (IMFG) was used to discriminate
between femoral neck samples extracted from osteoporotic
(OP) and osteoarthritic (OA) patients. IMFG values were
lower in OP compared to OA suggesting a higher
trabecular density in OA specimens. IMFG values were
lower in the metaphysis compared to subchondral section
in both OP and OA samples. These results are in
agreement with the packing of subchondral bone occurring
in OA. In subchondral section of OP specimens the higher
IMFG values are due to the marrow fat content increase
