摘要
BACKGROUND The main purpose of the article is to review the normal vertebral marrow and its appearance on MRI, including age-related changes and pathologic appearance based on routine MR sequences like T1, T2 & STIR. The signal intensity of the bone marrow depends mainly on the fat and water content. Each component has its appearance on MRI sequence that allows their differentiation. The red marrow is highly cellular, so it leads to a low signal intensity on T1-weighted sequences and high signal intensity on short tau inversion recovery (STIR) or fat-saturated T2-weighted sequences. Whereas, the yellow marrow presents an increased signal on T1-weighted sequences and low signal intensity on STIR or fat-saturated T2-weighted sequences. The differential diagnosis of pathological bone marrow includes degenerative changes, neoplasm, infection, and infiltrative marrow disorders. In this study, 30 cases were included, who presented with a chief complaint of neck pain, backache and radiculopathy who underwent MRI for evaluating the underlying pathology. The main objective of this study is to evaluate different MRI findings in these patients. METHODS Patients having neck pain, backache, and radiculopathy who presented in the Department of Radiodiagnosis at NRI Medical College and Hospital, Chinakakani, were included in the present study. On a random basis, 30 cases were included in the study, and all of them underwent routine MRI spine to a particular region according to the symptom. RESULTS Thirty patients were studied with an age range of 22 years to 80 years. In our study, out of 30 patients, 4 had fatty replacement of marrow, 3 had hemangioma, 6 had Modic endplate changes, 3 had metastases, 4 had osteoporosis, 5 had Koch's spine, 5 had myeloproliferative disease. Of the 4 patients who had osteoporosis, two patients had wedge compression fractures. CONCLUSION MRI is the sensitive tool in the imaging of vertebral marrow and imaging modality of choice in studying the bone marrow diseases. Routine sequences like T1, T2 & STIR sequences are the key for proper diagnosis and management of spinal pathology.
