How BDI works

Better/earlier detection of osteoporosis → Enables earlier treatment and fracture prevention

Works with any CT image containing vertebra or hip
(approximately 75% of all CTs¹):

chest, abdomen, pelvis, spine, cardiac CT, coronary angiogram, head/neck, lower extremity
taken within 12 months

BDI algorithms scan/analyze existing CT

Step 1

Vertebrae or hip detected; vertebrae segmented, measured, fracture detection
  • Automatically detects vertebrae or hip present on the scan
  • Segments individual vertebrae
  • Measures vertebral height
  • Identifies fractures

Step 2

Trabecular part of vertebra or hip detected
  • Detects the trabecular component of the vertebral or hip bones, excluding cortical bone

Step 3

Measures trabecular bone for each; determines bone density
  • Accurately measures and averages the Hounsfield units of trabecular bone within each vertebrae and hip, avoiding fractures.
  • Then puts into formula (BDI patented) to convert to bone density – adjusted for CT scanner, spinal and hip location.

Step 4

Calculates/reports T-Score, Z-Score, vertebral fracture presence and severity

  • Calculates & reports T-Score and Z-Score (gold standard metrics for osteoporosis analysis) by comparing bone density values to age , gender and race/ethnicity population assessments
  • Determines/reports any vertebral fracture presence and severity
  • We utilize the subject’s heart density, chest wall/abdominal or hip fat to calibrate the patient, CT scanner, and scan parameters to ensure the most accurate measure of individual BMD

Step 5

BDI expert physician reviews and finalizes report
  • Expert BDI Physician reviews, modifies if necessary, and finalizes report

Step 6

BDI Report
  • BDI final report in natural language
  • Sent to provider who ordered BDI osteoporosis screening and others as desired
