Osteo CT

This is an application package for the quantitative

assessment of vertebral bone mineral density for

the diagnosis and follow-up of osteopenia and osteo-

porosis.

The Basics

This program enables the quantitative determination

of bone mineral density of the spine in mg/ml of calcium

hydroxyapatite (CaHA) for the diagnosis, staging, and

follow-up of osteopenia and osteoporosis with CT. The

patient is scanned together with the water- and bone-

equivalent calibration phantom.

What is “T-score”?

This is the deviation of average BMD of the patient

from that of a young healthy control. It represents

bone loss with reference to the peak bone mass.

What is “Z-score”?

This is the deviation of average BMD of the patient

from that of a healthy person of the same age. It is an

indicator of biological variability.
