A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis). [1]
Radiographically, occult and subtle fractures are a diagnostic challenge. They may be divided into 1) high energy trauma fracture, 2) fatigue fracture from cyclical and sustained mechanical stress, and 3) insufficiency fracture occurring in weakened bone (e.g., in osteoporosis and postradiotherapy). Independently of the cause, the initial ...
Bone scintigraphy showing black marks where pelvic bone damage has occurred. Also known as a bone scan, bone scintigraphy involves the injection of a small amount of radioactive tracer into the bloodstream. This tracer decays and emits radioactive energy which can be detected by a special camera.
A skeletal survey (also called a bone survey [1]) is a series of X-rays of all the bones in the body, or at least the axial skeleton and the large cortical bones. A very common use is the diagnosis of multiple myeloma , where tumour deposits appear as "punched-out" lesions.
Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower.
DXA is only able to provide the areal bone mineral density. High-resolution peripheral quantitative computed tomography (HR-pQCT) is better than DXA at detecting bone microarchitecture, modeling whole-bone geometry using 3-dimensional information from scans. This method allows estimation of bone strength and other mechanical properties. [20]
A bone tumor might present with a pathologic fracture. [1] Other symptoms may include fatigue, fever, weight loss, anemia and nausea. [2] [3] Sometimes there are no symptoms and the tumour is found when investigating another problem. [2] [3] Diagnosis is generally by X-ray and other radiological tests such as CT scan, MRI, PET scan and bone ...
Complications may include nonunion of the fracture, avascular necrosis of the proximal part of the bone, and arthritis. [2] [1] Scaphoid fractures are most commonly caused by a fall on an outstretched hand. [2] Diagnosis is generally based on a combination of clinical examination and medical imaging. [2] Some fractures may not be visible on ...
