Quantitative computed tomography and predictive modelling for COPD exacerbations [PDF]

European Respiratory Review
In COPD, acute exacerbations (AECOPD) are major contributors to morbidity and mortality, emphasising the need for effective stratification of individuals at high risk. Quantitative computed tomography (qCT) refers to the extraction of numerical data from

Human Bone Typing Using Quantitative Cone-Beam Computed Tomography

International Dental Journal, 2023
Introduction: Bone typing is crucial to enable the choice of a suitable implant, the surgical technique, and the evaluation of the clinical outcome. Currently, bone typing is assessed subjectively by the surgeon.

Quantitative computed tomography and opportunistic bone density screening by dual use of computed tomography scans

Journal of Orthopaedic Translation, 2015
Central dual-energy X-ray absorptiometry (DXA) of the lumbar spine and proximal femur is the preferred method for bone mineral density (BMD) testing. Despite the fracture risk statistics, osteoporosis testing with DXA remains underused.
