Quantitative computed tomography ( QCT) is a medical technique that measures bone mineral density (BMD) using a standard X-ray computed tomography (CT) scanner with a calibration standard to convert Hounsfield units (HU) of the CT image to bone mineral density values. [1] Quantitative CT scans are primarily used to evaluate bone mineral density ...
A computed tomography scan ( CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.

Tomography is imaging by sections or sectioning that uses any kind of penetrating wave. The method is used in radiology, archaeology, biology, atmospheric science, geophysics, oceanography, plasma physics, materials science, cosmochemistry, astrophysics, quantum information, and other areas of science. The word tomography is derived from ...
Radiograph also shows that all vertebral bodies are intact without fracture. Pioneered at UCSF, quantitative computed tomography (QCT) is a test to measure bone mineral density (BMD). It is performed using a computed tomography (CT) scanner and results in a 3D image. Hip and lumbar spine are the most common choices for evaluation with QCT.
pQCT (peripheral quantitative computed tomography): 3D assessment of bone structure, composition and geometry at the radius and tibia. Like the HR-pQCT, the pQCT is a 3D imaging platform used to assess bone density and micro-architecture of the bones in the forearm and lower leg. Typical scans performed during a pQCT examination include the 4% ...
The term “ computed tomography ,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images, or “slices.”. These slices are called tomographic ...
