Abstract
The bone marrow is the largest organ of the body by weight next to bones, muscles and fat. It’s function is to provide a continuous supply of red cells and platelets and white cells to meet the body’s demands for oxygenation, coagulation and immunity (Vogler and Murphy, 1988).
The study of bone marrow abnormalities is taken in this thesis by conventional plain film radiology, radionuclide scintigraphy and computed tomography as well as MRI examination .
Accurate diagnosis of different bone marrow lesions is important to assess the disease stage as in lymphoma in order to imply the best treatment protocol according to it (Varan et al., 1999).
Combination of some or all diagnostic methods such as clinical ,imaging, histological and biochemical information is essential to bring out the correct diagnosis to each disease (Steiner et al., 1993).
Namely, the MRI has acquired an increasingly important role in evaluation of bone marrow lesions as it the best known modality of choice in discrimination between normal and abnormal bone marrow and in featuring the surrounding tissues (Steiner et al., 1993).
The aim of this work is to discuss the role of different radiological and imaging modalities in diagnosis of bone marrow lesions.
