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 (osteomyelitis). [1]
The radius is a long bone, prism -shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.
A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken. [1] In younger people, these fractures typically occur during sports or a motor vehicle collision. [2]
Bone as a material is very complex because of its hierarchal structure in which characteristics vary across length scales. [94] [95] At the basic scale, bone is composed of an organic matrix of collagen type-I. [94] Collagen type-I molecules form a composite material with hydroxyapatite to make up collagen fibrils. [95]
A bone scan of the affected limb may detect these changes even sooner and can almost confirm the disease. Bone densitometry can also be used to detect changes in bone mineral density. It can also be used to monitor the results of treatment since bone densitometry parameters improve with treatment. [citation needed]
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical ("diagnostic" radiography and "therapeutic") and industrial radiography. Similar techniques are used in airport security, (where "body scanners ...
Osteolytic lesion. Osteolytic lesion at the bottom of the radius, diagnosed by a darker section that indicates a loss of bone density. An osteolytic lesion (from the Greek words for "bone" (ὀστέον), and "to unbind" (λύειν)) is a softened section of a patient's bone formed as a symptom of specific diseases, including breast cancer ...
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 ...
