Laura Marie Fayad MD, Abstract Co-Author: Nothing to Disclose

1) There are a number of techniques available by MRI to differentiate normal red marrow interspersed with fatty marrow from bone marrow lesions. 2) Patterns in bone marrow signal changes by MRI are helpful for guiding the diagnosis towards marrow-replacing tumors, and differentiating stress reactions, osteomyelitis and arthropathy-related lesions. 3) Although T1 spin echo is vital to the characterization of bone marrow signal abnormalities, additional techniques, including chemical shift imaging, diffusion weighted imaging and perfusion imaging can be helpful for assessing bone marrow signal abnormalities.  

Normal bone marrow Basic principles of normal bone marrow composition and physiological bone marrow reconversion. Review of MRI techniques and technical considerations for imaging the bone marrow Conventional noncontrast sequences: T1 weighted, T2 weighted, chemical shift imaging Functional sequences: diffusion weighted imaging, contrast enhanced dynamic and static sequences Differentiating features of bone marrow abnormalities Tumors, stress-related injuries, infection, arthropathy-related signal changes Important pitfalls in assessing bone marrow signal changes Main pitfalls will be highlighted
