With age, the bone marrow undergoes structural changes, such as the reduced proportion of active blood-forming bone marrow and the decreased overall cellularity.
MRI can, however, also detect sequelae of inflammation consisting of fatty deposition in the bone marrow and chronic structural changes such as erosion and fusion of vertebral bodies [15].
Further, in radiographically normal tibiofemoral knee joints, subchondral bone changes, such as bone marrow lesions (BMLs) on MRIs, are common.
MRI, for instance, can depict earliest inflammatory joint changes such as bone marrow edema (BME), synovitis, or pre-erosion that are not visible on radiographs.
12, 13, 15 Most of the patients (60/76) had more than one ADR, and noncumulative changes such as peripheral neuropathy and bone marrow depression were observed, 12, 32 which can be perceived at any time during treatment.
MRI adds information about potential involvement of the spinal cord and nervous roots in addition to signs of disease activity and chronic changes such as fibrous pannus in RA and fatty marrow deposition, erosion and vertebral fusion in SpA.
15 The bone marrow studies reveal a severe decrease in cellularity and fat replacement, and nuclear changes, such as budding, double nuclear, and kariorrhexis in erythrocyte precursors.
Marrow metastases are easily demonstrated with MRI, but the changes tend to persist on follow-up such that marrow changes cannot be relied on to monitor response to treatment or disease progression.
Recurrences should be suspected when residual bone changes occur, such as marrow replacement, cortical disruption and osseous destruction.
He founded the Love Hope Strength Foundation (LHSF), which performs concerts across the globe to highlight the need for donors, dispel myths about donating marrow -- such as that it's very painful (technological advances have made it so that it's not) -- and conduct bone marrow drives.
