Overview

Automatic detection of often overlooked vertebral deformities

Duel-energy Vertebral Fracture Assessment (VFA) software helps you detect vertebral fractures, which can be difficult to diagnose. In fact, studies show up to half of all vertebral fractures are not diagnosed.1 Yet it is important to do so.  An existing vertebral fracture increases the risk for subsequent vertebral fractures three to 10 times, regardless of bone mineral density (BMD). Moreover, patients with an existing fracture and low BMD are 25 times more likely to fracture than those with normal BMD and no fracture.2 VFA enables detection of vertebral fractures, which helps you to provide effective care—before more severe complications occur.

Benefits

Clear visualization and automatic detection

By generating clear, dual-energy images, VFA helps you to detect vertebral fractures. It also provides a clear skeletal image by minimizing the appearance of soft-tissue artifacts around vertebral bodies, particularly in the thoracic region. 

In addition to providing a clear spine visualization, VFA also automatically calls attention to problem areas. And by making the vertebrae visible and automatically classifying deformations, VFA helps you diagnose vertebral fractures that are often missed, and allows you to begin preventative treatments.

Technology

The technological advantages of VFA that can help you diagnose your patients include:

VISIBILITY

  • Clear dual-energy images in three minutes with direct-to-digital detector technology
  • Comparable to conventional X-ray in identifying and classifying vertebral deformations concerning etiology grade and shape (Lunar iDXA only)
  • Minimal interference of soft-tissue artifacts around vertebral bodies, especially in thoracic-vertebrae views
  • Slide bar to adjust contrast and brightness for bone-edge enhancement 

AUTOMATION

  • Morphometry Wizard automatically labels vertebral deformations with a six-point measurement of the anterior, posterior and mid-heights of vertebrae
  • Lateral-spine morphometry reference values to enable comparison to normals
  • DICOM-compatible images for easy electronic storage and access
