3-705. MedlinePlus. 003833. A bone scan or bone scintigraphy / sɪnˈtɪɡrəfi / 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 ...
88.31. 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. The standard set of X-rays for a skeletal survey includes X-rays ...
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

PET for bone imaging. Positron emission tomography for bone imaging, as an in vivo tracer technique, allows the measurement of the regional concentration of radioactivity proportional to the image pixel values averaged over a region of interest (ROI) in bones. Positron emission tomography is a functional imaging technique that uses [18 F]NaF ...
Dual-energy X-ray absorptiometry. Dual-energy X-ray absorptiometry (DXA, or DEXA[1]) is a means of measuring bone mineral density (BMD) using spectral imaging. Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted out, the bone mineral density (BMD) can be determined from the ...
Gorham's disease (pronounced GOR-amz), also known as Gorham vanishing bone disease and phantom bone disease, [1] is a very rare skeletal condition of unknown cause.It is characterized by the uncontrolled proliferation of distended, thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement of bone with angiomas and/or fibrosis.
Common [4] A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1][4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from ...
Oncology, orthopedic surgery. Giant-cell tumor of the bone (GCTOB), is a relatively uncommon bone tumor. It is characterized by the presence of multinucleated giant cells (osteoclast -like cells). Malignancy in giant-cell tumor is uncommon and occurs in about 2% of all cases. However, if malignant degeneration does occur, it is likely to ...
