THE HOLOGIC® QDR 4500 A ELITE DENSITOMETER is the most sophisticated and fastest multi-detector bone densitometer available today. It is characterized by:

• Automatic and Permanent Calibration System unique to Hologic® offering guaranteed accuracy and stability of results.
• Rapid bone densitometry makes it possible to scan the lumbar spine in 30 seconds, hip in 30 seconds & whole body in 180 seconds.
• Minimal radiation exposure to both patient & operator, much less than a routine chest X-Ray or airplane trip.
  

Wide range of applications :
-    Bone Density Study - two sites: Lumbar Spine L1-L4 for the trabecular Bone & Femoral
     Bone of the Hip for the Cortical Bone
-    Whole Body Bone Density Study for the study of genetic Diseases in children &
     Diseases of Bone Metabolism .
-    Others Sites such as forearm, heel, & others.

TESTS PERFORMED EXCLUSIVELY IN JOC:
-    Supine Lateral Spine: allows the exact measurement of the trabecular bone of the spine
  
-    Body Composition Analysis for the precise evaluation of fatty to non-fatty mass in order
     to treat obesity.
   
-    Morphometry of the Lumbar Spine: to monitor deformity of the spine due to fractures
     caused by osteoporosis, by measuring the vertebral height.
  
-    Metal Removal Study: allows measurement of bone density around the prosthesis by
     exclusion of the prosthesis from the measurement.
