Radiographic features. Decreased bone density can be appreciated by decreased cortical thickness and loss of bony trabeculae in the early stages in radiography. Bones like the vertebra, long bones (proximal femur), calcaneum and tubular bones are usually looked at for evidence of osteoporosis.
The hallmark feature of osteogenesis imperfecta is osteoporosis and fragile bones that fracture easily, as well as, blue sclera, dental fragility and hearing loss. There is extreme variation in clinical symptoms based on genetic basis and subtypes.
Radiographic features Plain radiograph. Plain films and OPGs may not demonstrate early disease 1,3. When visible, features are non-specific and include 1,7: poorly defined lucent, mixed or sclerotic lesion. sequestrum. periosteal proliferation. destruction of adjacent structures. CT
Paget disease of the bone is a common, chronic metabolic bone disorder characterized by excessive abnormal bone remodeling. The classically described radiological appearances are expanded bone with a coarsened trabecular pattern. The pelvis, spine, skull, and proximal long bones are most frequently affected.
Osteomalacia is bone softening due to insufficient mineralization of the osteoid secondary to any process that results in vitamin D deficiency or defects in phosphate metabolism: high remodeling rate: excessive osteoid formation with normal/little mineralization.
Radiographic features. MRI has the highest accuracy to detect osteomyelitis with a sensitivity of 90% and specificity of ~80% 21. In some instances, imaging features are specific to a region or a particular type of infection, for example: subperiosteal abscess. Brodie abscess.
osteoporosis: initially juxta-articular, and later generalized; compounded by corticosteroid therapy and disuse. joint space narrowing: symmetrical or concentric, uniform. Hands and wrists. Diagnosis and follow-up of patients with rheumatoid arthritis commonly involve imaging of the hands and wrists.
Radiographic features. Radiology has a number of roles in the diagnosis and management for multiple myeloma: suggest the diagnosis / exclude other causes. assess possible mechanical complications (e.g. pathological fracture) assess disease progression
Radiographic features. Key radiographic features are joint space narrowing, subchondral sclerosis, and osteophytosis. If all three of these findings are not present, another diagnosis should be considered. With the increasing use of MRI in the assessment of osteoarthritis, other findings have been studied, such as bone marrow lesions and synovitis.
Radiographic features. In the growing skeleton, the deficiency of normal mineralization is most evident at metaphyseal zones of provisional calcification where there is an excess of non-mineralized osteoid resulting in growth plate widening and abnormal configuration of the metaphysis: fraying: indistinct margins of the metaphysis
