Hologic is the international leader in bone density testing and the Discover series represents 40 years of research and development effort into scientific field. Since 1986, we have relied with confidence on Hologic technology for testing 20,000+ patients at the Osteoporosis Center of Atlanta and hundreds of patients participating in demanding US FDA regulated research studies for the Atlanta Research Center. The exacting demands our two institutions place on our densitometer has been met through our staying with Hologic’s top of the line research densitometers. Through the years, we have learned we can depend on the performance, quality, and accuracy of this line of devices. We are the only center in the Southeast region, including the medical schools, which provide this level of bone densitometry technological and professional service to our clinical and research patients.
The Discovery 4500A Research DXA technology includes:
- High-resolution digital detector array, which improves fracture detection visualization of abdominal aortic calcifications
- Speed and image quality, with images of the hip and spine captured in as fast as 10 seconds.
- Superb visualization, an exclusive Hologic design that utilizes a high-resolution detector array paired with true fan-beam linear acquisition geometry
- Continuous automatic calibration, ensuring precise and consistent measurements results from exam to exam.
- The Discovery DXA system offers exceptional precision and accuracy to help you identify patients with osteoporosis and/or who are at risk for fractures.
High Definition Vertebral Fracture Assessment (IVA-HD)
The IVA-HD tool dramatically improves the detection of vertebral fractures by doubling the resolution of previously available techniques with a low-dose, single-energy image. Vertebral fracture status, combined with traditional bone density testing, is the gold standard for fracture risk assessment.
Detection of Abdominal Aortic Calcification
The IVA-HD tool also allows you to visualize calcified plaques in the abdominal aorta, which may be a significant indicator of heart disease and stroke. Exclusive to Hologic, this feature provides vital information that may link to coronary heart disease (CHD), which is the leading cause of death for women. In fact, nearly 39 percent of all female deaths in the U.S. are due to CHD.
Advanced Body Composition Assessment and Inner Core Visceral Fat Assessment
The Advanced Body Composition assessment feature produces color images displaying the distribution of fat, lean mass, bone, and fat mass index. The information is translated into an easy-to-interpret report for improved patient management and counseling.
Our DXA systems incorporate the National Health and Nutrition Examination Survey (NHANES) whole body composition reference data. The Endocrine Society recommends annual bone mineral density and body composition exams for bariatric surgery patients.
FRAX* 10-year Fracture Risk Assessment
The FRAX fracture risk assessment tool calculates a patient’s 10-year probability of hip and other osteoporotic fractures. FRAX was developed by the World Health Organization (WHO) to help healthcare providers identify and proactively treat patients with a high risk of debilitating bone fractures due to low bone mass and other significant risk factors.
FRAX is a trademark of the World Health Organization Collaborating Centre for Metabolic Bone Diseases, located at the University Of Sheffield Medical School, UK.
