Imaging

Quantitative computed tomography is a procedure which uses CT scan for quantitative assessment of the bones or bone mineral density. It is mainly used in osteoporotic patients.  By Osteoporosis is a skeletal disease, characterized by low bone mass and micro-architectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. […]

Bone mineral density or bone density is measure of mineral content in per square centimeter of bones. Bone mineral density is an indirect indicator of osteoporosis. Densitometery is the test for measurement of bone mineral density. As we grow after reaching peak bone mass, we lose some bone mass because of loss of bone minerals […]

DEXA [Now abbreviated as DXA] or dual-energy x-ray absorptiometry is a technique used to measure bone density. Dexa scan involves passing two X-ray beams with different energy levels are aimed at the patient’s bones, and bone mineral density is determined from absorption of each bone after soft tissue absorption is subtracted out. The test is […]

Stress views are special x-ray views in which radiograph of the part examined is done after applying requisite stress. Stress views are important in the evaluation of ligamentous tears, joint stability, and fracture unions. For example, stress views in the hand are usually ordered if there is an injury to the ulnar collateral ligament of […]

Radiogrammetry is a technique that uses a conventional radiograph for the assessment of bone status by using cortical width as a measure of bone strength. Osteoporosis is defined as a systemic skeletal disease characterized by low bone mass and micro-architectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fractures.
