The orange and yellow areas are those where the BMD is low compared with the mean value measured from a large group of subjects known NOT to suffer from osteoporosis.
Osteoporosis is a major health problem, and carries with it a high risk of fracture.
It can be seen that all of the examples have areas coloured yellow and orange, even although only individuals C and D are known from other tests to suffer from osteoporosis. Our image analysis work aims to derive measures of the distribution of mineralisation to improve discrimination.
