What Student Need to Know about Imaging of the Musculoskeletal System In Radio Diagnosis
In clinical practice various modalities are used for wholebody imaging of the musculoskeletal system, including radiography, bone scintigraphy, computed tomography, magnetic resonance imaging (MRI), and positron emission tomographycomputed tomography (PETCT). Multislice CT is far more sensitive than radiographs in the assessment of trabecular and cortical bone destruction and allows for evaluation of fracture risk. The introduction of combined PETCT scanners has markedly increased diagnostic accuracy for the detection of skeletal metastases compared with PET alone. The unique softtissue contrast of MRI enables for precise assessment of bone marrow infiltration and adjacent soft tissue structures so that alterations within the bone marrow may be detected before osseous destruction becomes apparent in CT or metabolic changes occur on bone scintigraphy or PET scan. Improvements in hard and software, including parallel image acquisition acceleration, have made high resolution wholebody MRI clinically feasi
