  Authored by John Schousboe, MD, Park Nicollet Clinic & Specialty Center, MN, this whitepaper discusses how VFA imaging at the time of a bone density test is aconvenient and efficient way of identifying patients with one or more prevalent vertebral fractures. This aids in identifying those at high risk of subsequent fracture and for whom fracture prevention therapies are indicated.

  The purpose of this study was to identify spinal fracture prevalence in men and women over the age of 40. Often, spinal fractures are overlooked or not recognized and these types of fractures are frequently of substantial medical significance. This is the first study to assess the prevalence of spine fractures in a nationally representative sample of the United States.   Please visit PubMed for the full text article.

This chart simplifies a highly complex topic for patients’ informational use, by outlining common imaging examination methods and their associated approximate effective radiation dose. The effective doses are typical values for an average-sized adult. The actual dose can vary substantially, depending on a person’s size as well as on differences in imaging practices. It is also important to note that doses given to pediatric patients will vary significantly from those given to adults, since children vary in size. Patients with radiation dose questions should consult with their radiation physicists and/or radiologists as part of a larger discussion on the benefits and risks of radiologic care.

  Introduction: The Horizon® DXA systems are Hologic’s latest generation of bone densitometers and the only densitometers to use ultra-fast, high output ceramic detectors and a high frequency, pulsing x-ray generator. Horizon system’s latest digital detector and x-ray technology combine to provide the ability to measure a wide range of clinical patients, including the morbidly obese, with unsurpassed image quality and long-term stability, all in a flexible platform designed for future enhancements.

Abstract: Over the last decade obesity has exploded to epidemic proportions in America. Obesity-related health risks include coronary heart disease, type 2 diabetes, stroke, dyslipidemia, and certain types of cancers. Traditional anthropomorphic measures of obesity like BMI and waist circumference quantify excess weight or size, not excess fat, and misclassify patients by failing to assess pathogenic visceral fat depots. DXA visceral fat measurements may be superior to traditional measures for evaluating obesity-related disease risk. The available literature supports visceral fat thresholds of 100 cm2 for increased risk and 160 cm2 for high risk and suggests this classification scheme may identify patients most likely to benefit from preventive interventions.

Introduction: Instant Vertebral Assessment (IVA) has become a valuable and increasingly utilized tool to assess patients at risk of osteoporosis for the presence of vertebral fractures. During an IVA scan, sufficient soft tissue anterior to the lumbar spine can be included to allow for the detection of calcified plaques in the abdominal aorta. There is good agreement between IVA and lateral radiographs for the detection of AAC,12 similar to the agreement between the two modalities for vertebral fracture detection.13, 14 Thus, the same diagnostic test can be used to measure strong risk factors for two highly prevalent public health problems, osteoporosis and cardiovascular disease.

Abstract: The ability to monitor patient response to osteoporosis therapy with DXA depends on long-term in vivo precision and expected treatment response to therapy at a particular region. A review of recent peer-reviewed literature (57 studies) of short-term in vivo coefficient of variations (CV’s) found a statistically significant difference between manufacturers for the AP spine and femoral neck, but not for the total hip.
