The standard set of X-rays for a skeletal survey includes X-rays of the skull, entire spine, pelvis, ribs, both humeri and femora (proximal long bones). It is more effective than isotope scans at detecting bone involvement in multiple myeloma. Although significantly less sensitive than MRI, it is easier to include more bones. A study found that ...
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).
where, is a convolution operator, C bone (t) is the bone tissue activity concentration of tracer (in units: MBq/ml) over a period of time t, C plasma (t) is the plasma concentration of tracer (in units: MBq/ml) over a period of time t, IRF(t) is equal to the sum of exponentials, β values are fixed between 0.0001 sec −1 and 0.1 sec −1 in ...
For example, skeletal signs of rickets are seen predominantly at sites of rapid growth, including the proximal humerus, distal radius, distal femur and both the proximal and the distal tibia. Therefore, a skeletal survey for rickets can be accomplished with anteroposterior radiographs of the knees, wrists, and ankles. [20]
The change in the position (translation and rotation) of the prosthesis markers relative to the bone markers is then determined. The reported accuracy of RSA ranges between 0.05 and 0.5 mm for translations and between 0.15˚ and 1.15˚ for rotations (95% confidence interval ). [ 6 ]
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]

Individuals that are diagnosed with bone disorders need to pay attention to secondary causes as medications and the presence of other disorders can also have major effects. Drugs that can prevent bone loss are called antiresorptives. They can slow the degradation of the skeletal system and decrease the risk of subsequent bone injuries fractures.
