Comparison of dual X-ray absorptiometry (DEXA), digital X-ray radiogrammetry
(DXR), and conventional radiographs in the evaluation of osteoporosis and bone erosions in patients with rheumatoid arthritis.
Quantitative radiology: radiogrammetry
of cortical bone.

COPENHAGEN -- MRI, ultrasound, and digital x-ray radiogrammetry
may all have a role in identifying which patients with early, nonerosive rheumatoid arthritis will later develop erosive disease, based on results from a pilot study with 27 patients.
Considering invasive, ionizing, and non-ionizing techniques, they discuss such topics as microscopy and related techniques, radiogrammetry
, and quantitative ultrasound.
He and associates used digital x-ray radiogrammetry
to evaluate the changes in cortical bone thickness among 40 postmenopausal women with osteoporosis, 28 of whom received 20 [mu]g or 40 [mu]g of teriparatide daily for 1 year.
