The role of magnetic resonance imaging in the diagnosis of malignant bone neoplasms. Current state of an issue
The review article is about clinical experience in the use of modern tomographic methods (magnetic resonance imaging (MRI) and X-ray computed tomography (CT)) in the diagnosis and assessment of the progression of malignant bone neoplasms, summarizing the results of the largest studies demonstrating the comparative characteristics of the methods. Numerous data demonstrate high sensitivity of MRI and form the following diagnostic tasks that can be solved by this method: the involvement degree of soft tissues in the pathological process, damage to the neurovascular bundle, the articular surface, assessment of the extent of tumor in the bone marrow canal. At the same time, CT shows a higher sensitivity in assessing cortical destruction and the degree of matrix mineralization. The article discusses the variety of program sequences and modes of MRI scanning, the prospects of the method in assessing the prevalence, staging, and differential diagnosis of bone tumors.
