Description détaillée
The ratio of fat to water in the bone marrow depends on the cellularity of the bone marrow. In addition to the water/fat ratio in bone marrow there are also other parameters for quantitative MRI assessment. These include the apparent diffusion coefficient (ACD), the T1 relaxation time, mapping of the macromolecular proton fraction. The undoubted advantage of MRI is its non-invasiveness and the ability to assess any localization of the bone marrow.
MRI may become a new non-invasive method for assessing the ratio of fat to cells in the bone marrow in children with hematological malignancies, which can help in making a diagnosis and monitoring the response to therapy.
