Dual-Energy X-ray Absorptiometry (DEXA) Medical Imaging Services in Zambia

Abstract

: Dual-energy X-ray absorptiometry (DEXA) is a medical imaging technique that uses low radiation for the diagnosis of osteoporosis. Millions of people are suffering from osteoporosis globally. The disease causes the bones to lose their strength and become more fragile and susceptible to fractures. The common risk factors of developing osteoporosis include aging, antiretroviral therapy (ARV) medication, and long-term corticosteroid medication. The morbidity and mortality of the disease arises from the associated fractures and medical complications. Although DEXA imaging services are available in the country, they remain underutilised. This article aims at bringing awareness and reviewing the DEXA imaging services in Zambia. The review found a lack of data on the prevalence of osteoporosis in Zambia. To improve the DEXA imaging services, research is required on epidemiology of the disease, associated fractures and projected costs incurred due to hospitalisation of patients.
