Abstract
Background: Hematologic diseases are a group of prevalent and clinically diverse diseases that can affect any organ system. Hematologic disorders frequently involve bone and associated tissues causing significant alterations in the bone marrow and may have relevant side effects on the skeleton. In order to evaluate findings in bone marrow on MR imaging, it is essential to understand the normal composition and distribution of bone marrow and the changes in marrow that occur with age, as well as the basis for the MR signals from marrow and the factors that affect those signals.
Aim of the Work: To describe the musculoskeletal MRI findings in patients with hematological diseases.
Patients and Methods: cross sectional study was conducted in Ain Shams University hospitals on patients confirmed with hematological disease undergoing musculoskeletal MRI.
Conclusion: Magnetic resonance imaging is very beneficial noninvasive modality to evaluate bone marrow and detecting marrow lesions due to its ability to provide information at the level of cellular and chemical composition. Knowing normal marrow components and composition and their variation, as well as of factors that affect MR signal intensity, is important for optimal interpretation of MR images. The signal intensity, morphology, and location of marrow findings on MRI can be used to provide accurate diagnoses and to guide treatment of the discussed hematological diseases.
