[en] Dual photon absorptiometry allows quantitative investigation of the vertebral mineral content. The authors report the bone mineralization regression curves they obtained with their prototype in male and female controle subjects. There is a fracture threshold, unconnected with age, between normal and osteoporotic subjects. DPA results correlate well with those of Quantitative Computed Tomography. DPA can be used to monitor patient's mineralization and detect subjects at increased risk for fractures

L'absorptiometrie biphotonique rachidienne permet une etude quantitative de l'etat de mineralisation du rachis. Utilisant leur prototype, les auteurs rapportent les courbes de decroissance de la mineralisation osseuse qu'ils ont obtenues chez des sujets temoins feminins et masculins. Il existe un seuil fracturaire, independant de l'age, separant les populations temoin et osteoporotique. Les resultats de l'ABR sont bien correles a ceux de la tomodensitometrie. L'ABR permet la surveillance de l'evolution des patients ainsi que le depistage des sujets a risqueJournal

[en] With quantification techniques of the spinal bone condition, especially with spinal biphotonic absorptiometry, early screening of patients risking subsequent development of osteoporosis complicated with vertebral compression is possible. An investigation was conducted in Lower Normandy, in 386 women who had undergone menopause or an ovariectomy, with ages ranging between 40 and 56 years; 274 were in a peri-menopausal state. A curve of the bone mineral content according to age was previously established. From this curve, in semilogarithmic representation, each patient risk was assessed. This risk is considered as high in 30 p. cent of the patients, non existent in 52 p. cent and 18 p. cent are borderline. The percentage of high risk patients increases with the number of years since menopause. It is hoped that the incidence of osteoporosis will decrease with early screening and preventive therapeutic measures

Grace aux techniques de quantification de l'etat osseux rachidien, tout particulierement l'absorptiometrie biphotonique rachidienne, le depistage precoce des sujets risquant de presenter ulterieurement une osteoporose compliquee de tassements vertebraux est possible. On a realise une enquete en Basse-Normandie chez 386 femmes, menopausees, agees de 40 a 56 ans; 284 d'entre elles etaient en peri-menopause. On avait precedemment etabli une courbe du contenu mineral osseux en fonction de l'age. A partir de cette courbe, en representation semi-logarithmique, on estime le risque de chaque sujet. Ce risque est considere eleve chez 30 p. cent des sujets, nul chez 52 p. cent, 18 p. cent se situant dans une zone frontiere. Le pourcentage des sujets a risque eleve croit avec le nombre d'annees ecoulees depuis la menopause. On peut esperer que l'incidence de l'osteoporose diminuera grace au depistage precoce et aux mesures therapeutiques preventivesJournal

[en] The systems currently found on the market enable whole-body scintigraphs to be obtained with a cine-camera, but all are designed for use with one type of camera alone. The whole-body system developed here is independent of the make of camera and offers all the possibilities of computer treatment. The various stages of an examination carried out with this apparatus are described

Les systemes trouves actuellement sur le marche permettent la realisation de scintigraphies corporelles totales a l'aide d'une camera. Mais tous ces systemes sont etroitement lies a un type de camera. On a realise un systeme d'imagerie corps entier independant de la marque de la camera et apportant toutes les possibilites de traitement par un calculateur. On enumere les differentes etapes d'un examen realise au moyen de ce systemeSource
