Knowledge of the appearances of normal bone marrow, metastases involving marrow, and therapy-related marrow changes shown by MR imaging is necessary in order to avoid misdiagnosis. This article reviews MR imaging techniques and the findings that allow distinction of normal yellow (fatty) marrow and red marrow from tumor in marrow, as well as the identification of marrow changes resulting from radiation therapy or treatment with marrow-stimulating drugs in patients with musculoskeletal tumors.

We demonstrated the feasibility of 7 Tesla sodium (23Na) and chlorine (35Cl) MRI of a solitary enchondroma. For this, we established dedicated sequences on a 7-Tesla whole-body system with the following key parameters for 35Cl MRI: TE/TR = 0.35/60 ms, TRO = 5 ms, α = 90°, Δx3 = (6 mm)3, 3 averages, Tacq = 30 min and for 23Na MRI: TE/TR = 0.4/101 ms, TRO = 10ms; α = 90°; Δx3 = (1.9 mm)3, 3 averages, Tacq = 30 min 18 s. The measured apparent Na+ concentration was 255 mmol/l and was approximately 7-fold higher than the apparent Cl– concentration with about 36 mmol/l. Additionally, repeated proton MRI examinations demonstrated constant but subtle growth (≈ 0.65 ml/year) over 14 years. In conclusion, enchondromas obviously have a high contrast-to-noise ratio when compared with the normal bone marrow in 23Na and 35Cl MRI, which may contribute to detection and differentiation in unclear or subtle cases.
