Effects of thyroid hormone - Bone
  Gómez Acotto et al., Buenos Aires, Argentina, and Lyon, France, measured bone mineral density, using ultrasound measurement of the calcaneus and densitometry of lumbar spine, femoral neck, and total body in 9 patients with hyperthyroidism before treatment and after 24 months of antithyroid therapy. Results were compared with matched controls. Both ultrasound and bone densitometry showed rapid increase of bone mineral content after initiation of therapy. It is concluded that ultrasound is an accurate and highly reproducible method for the assessment of bone mineral content.
