MR Imaging of Bone Marrow in Patients with Musculoskeletal Tumors
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 r...
متن کاملThe Role of Bone Marrow Aspiration and Bone Marrow Biopsy in Diagnosis of Bone Marrow Metastases
Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...
متن کاملMR bone imaging
Background/introduction Bone is highly relevant to focused ultrasound therapy, both as a potential treatment target and because it interferes with treatment of other organs such as the brain. It is challenging to image cortical bone using MRI, however, due to low water density and fast signal decay in bony tissues. Ultrashort echo time (UTE) imaging is a specialized MR technique that allows the...
متن کاملBone Marrow Imaging
(1) Background Bone marrow is the body’s 4 largest organ constituting 5% of its body weight. It consists of trabecular bone and a variety of cells including hematopoetic, fat, stroma and RES cells as well as sinsusoids. Bone marrow composition changes with age, which is reflected in a change in signal characteristics in MR images. Red marrow, which is found in younger individuals is composed of...
متن کاملBone marrow reconversion – imaging of physiological changes in bone marrow
Reconversion of bone marrow is a reverse process of natural replacement of red marrow by yellow marrow. The occurrence of reconversion can be misleading and challenging in interpretation of musculoskeletal system imaging. Changes of signal intensity in bone marrow are frequently observed in radiological routine and its diversity can cause a suspicion of pathologic findings. Therefore, the knowl...
