“…The dose rates in air measured during this equine scintigraphy are fully comparable to the data published in the literature (Attenburrow andVennart, 1989: Whitelock, 1997) within the framework of measurements taken under conditions similar to those for this study. Despite the relatively high values of the dose rates in air, the use of appropnate radiological protection during the examination leads to an annual effective dose of less than 1 mSv.…”

RÉSUMÉ (MuriLiscript recrivrd 12 July 2002, nccrptrd 14 Novemhrr 2002)Following a request from the Permanent Secretary of the French Commission for Artificial Radiodement3 (CIREA) engaged to investigate a request for a licence related to a new scintigraphy unit dedicated to equidae, a dosimetric assessment concerning the personnel attending the examination was carried out. This scintigraphy unit depends on the Goustranville Centre for lmaging and Research on the Locomotive Diseases of Equidae (CIRALE) in the Calvados region. The dosimetric assessment was carried out for the different operators during the successive stages of the scintigraphic examination. Assuming 150 examinations per year, the annual equivalent dose to the fingers skin is 150 mSv maximum for the technologist and 2 mSv for the veterinary surgeon; the annual effective dose ranges from 0.15 to 0.45 mSv, depending on the operators.Scintigraphie équine : estimation de la dose reçue par le personnel.Suite à une demande du Secrétariat permanent de la Commission interministérielle des radioéléments artificiels (CIREA) amené à instruire une demande d'autorisation relative a une nouvelle installation dédiée à la scintigraphie équine, une évalualion dosimétrique concernant le personnel présent lors de l'examen a été réalisée. Cette installation dépend du Centre d'imagerie et de recherche sur les affections locomotrices des équidés (CIRALE) situé à Goustranville dans le Calvados. L'évaluation dosimétrique a été réalisée pour les différents opérateurs au cours des étapes successives de l'examen scintigraphique. En prenant l'hypothèse de 150 examens par an, l'équivalent de dose annuel i la peau des doigts est au maximum de 150 mSv pour le manipulateur et de 2 mSv pour le vétérinaire ; la dose efficace annuelle est quant à elle comprise entre 0,15 et 0,45 mSv selon les opérateurs.

“…In causing lameness they make a significant contribution to wastage and failure to race (Jeffcott et al 1982;Rossdale et al 1985). In recent years, considerable improvements have been made in the diagnosis of skeletal disease and assessment of bone quality through the use of noninvasive methods such as ultrasonography (Jeffcott and McCartney 1985), photon absorptiometry (Jeffcott et al 1986) radioisotope bone scanning (Attenburrow et al 1984;Pilsworth and Webbon 1986) and force plate gait analysis (Dow er al. 1991).…”

Summary Biochemical markers of bone metabolism were analysed in serum samples obtained from 60 horses with no history of orthopaedic disease (age 3 months‐20 years). Serum levels of the carboxyterminal propeptide of type I procollagen (PICP), a marker of bone formation and the pyridinoline cross linked telopeptide domain of type I collagen (ICTP), a putative marker of bone resorption, were measured by radioimmunoassay (RIA). Serum levels of the bone specific isoenzyme of alkaline phosphatase (BALP), another marker of bone formation, were measured by a wheatgerm agglutinin affinity (WGA) method. Total alkaline phosphatase levels were also determined. Serum levels of PICP were significantly correlated with bone ALP (r=0.78, P<0.0001) and ICTP (r=0.87, P<0.0001). ICTP levels also correlated significantly with bone ALP (r=0.81, P<0.0001). However, total alkaline phosphatase did not correlate significantly with PICP, ICTP and BALP in horses over 1 year of age. There was an inverse correlation between serum levels of all biochemical markers and age of animals, with the most significant changes seen over the first 2 years. In animals less than 1 year of age, the reference ranges (mean ± s.d. 1.96) were as follows: PICP 1216–2666 μg/l, ICTP 13.8–26.7 μg/l, bone ALP 134–288 u/l and total ALP 223–498 u/l. In 2‐year‐olds, the equivalent reference ranges were: PICP 550–1472 μg/l, ICTP 7.96‐22.8 μg/l, bone ALP 32.7–125 u/l and total ALP 134–238 u/l. Assays for bone ALP and antigens that reflect collagen metabolism display significant potential as sensitive non invasive methods of evaluating bone metabolism in the horse.

“…Gamma-scintigraphic examination of bone (bone scanning) using a hand held probe detector was originally developed and described by D. Attenburrow and his colleagues in a collaborative effort between a private practice and the Department of Physics, University of Exeter (Attenburrow et al 1984). Following Attenbumow's introduction of the technique, other workers adopted similar examination protocols.…”
