Major Upgrade in Imaging Technology

ImageCare is proud to announce the recent addition of a major upgrade in our outpatient imaging technology – Hologic’s Discovery dual energy X-ray absorption (DEXA) system.

About DEXA

Measurements of body composition have been used to study how lean body mass and body fat change during health and disease.      Body composition changes are common in people with HIV infection.  Wasting in this population has been well documented. More recently, fat redistribution syndrome or lipodystrophy has become increasingly common in people receiving highly active antiretroviral therapy (HAART).

DEXA systems assess body composition by measuring the differential absorption of x-rays at two frequencies and can separate tissue into fat, lean, and bone mineral.  DEXA is relatively easy to administer and uses a very low level of radiation, approximately 1/6 to 1/2 the exposure from a standard chest x-ray.  DEXA measurements correlate well with other methods that assess body composition.
