REMS processes the raw, unfiltered ultrasound signals acquired during an echographic scan of the axial sites, femur and spine. The analysis is performed in the frequency domain. Bone mineral density is estimated by comparing the results against reference models. The accuracy has been tested by comparing it against to DXA technology. [1] [2] [3] [4]
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]
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]
DXA scans can also be used to measure total body composition and fat content with a high degree of accuracy comparable to hydrostatic weighing with a few important caveats. [18] [specify] From the DXA scans, a low resolution "fat shadow" image can also be generated, which gives an overall impression of fat distribution throughout the body. [19]
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 ...
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.

Because bone tumors can appear at this location, X-ray imaging is necessary following a fracture diagnosis. The standard procedure is the shoulder-SAFE algorithm. [ 15 ] The sensitivity of the method in comparison with X-ray imaging is 94.4 percent, and the specificity is 100 percent.
