Difusion and Functional Sequences: Utility in the Study of Bone and Soft Tissue Tumors. Pictorial Review
Keywords:
Magnetic resonance imaging, Diffusion, Bone neoplasmsAbstract
Magnetic resonance imaging (MR) is the preferred technique for the diagnosis, characterization, staging, follow-up and assessment of response to treatment of musculoskeletal tumors. Conventional sequences help to classify these lesions. Recently new evolving functional MR sequences with advanced techniques have been implemented, such as phase sequence, opposite phase, diffusion, perfusion and spectroscopy, which provide specific information about the behavior, physiology, metabolism and molecular biology of the tumor. These sequences are non-invasive and provide additional qualitative, quantitative, metabolic and vascular information, making them important for the diagnosis and monitoring of bone and soft tissue tumors. This article reviews the technique of these sequences, particualrly the diffusion technique, using illustrative cases from the Hospital Pablo Tobon Uribe (Medellin – Colombia) and the University Hospital Quirón Salud (Madrid – Spain). We aim to review the utility and importance of a combined analysis of these new tools, which will provide additional information for adequate characterization, diagnosis and response to treatment of tumor lesions in the musculoskeletal system.
