[Bone scintigraphy in Paget's disease].

Sixty patients with Paget's disease underwent bone scintigraphy and a radiological and biological exam. The use of scintigraphy in this disease is of double importance: it allows the spread of the disease to be diagnosed without doing X-rays of the entire skeleton. In twenty per cent of cases this disease cannot be located using X-rays and is detected by scintigraphy. It also supplies an additional objective criteria for judging the development of this disease, especially under treatment. The authors study the different hypotheses concerning the fixation to the bone of the isotope tracer in the Paget zone.
