- Abstract
- Osteoporosis is considered as a major public
health problem, second only to cardiovascular diseases. The
gold standard for its diagnosis is currently represented by
dual energy X-ray absorptiometry (DXA), which, however,
suffers from some important drawbacks. In order to
overcome such limitations, the use of ultrasound (US)
techniques has been proposed. In this paper, a novel
approach to the diagnosis of osteoporosis through US scans
on lumbar spine and proximal femur is described. The
approach relies on the estimation of diagnostic parameters
by measuring the degree of similarity between the spectra of
the raw radiofrequency (RF) echo signals and reference
spectral models of osteoporotic or healthy bones. Reference
models are representative of the features of either
osteoporotic or healthy bone structures and are matched
with subject age, sex, ethnic group and body mass index to
take into account variations in bone physiological condition
and subject anatomy. In this paper, the methods
implemented to build the database of reference models and
to estimate diagnostic parameters are presented. The
performance of the approach was assessed on a total of 145
Caucasian underweight and normal-weighted women with
age in the range from 46 to 55. Performance was assessed
through direct comparison with DXA results. The obtained
median relative error in the estimation of bone mineral
density was as low as 9.1% on women aged 51 to 55 years
and 12.0% on women with age in the range from 46 to 50
years. Moreover, for the two groups, the estimation error
was lower than 20% for 81% and 78.6% of subjects,
respectively. Therefore, the proposed method combines the
advantages of the use of US techniques with a remarkable
diagnostic accuracy, thus lending itself to the possibility of
being used for population mass screenings. (literal)
