[Simultaneous scintigraphy exploration using MDP - 99 Tc and 67GA in infectious osteoarticular pathology. Initial results].
A new investigation in infectious osteoarticular pathology is presented, involving the use of two tracers: one for bone metabolism (MDP - 99mTc), the other for the infectious process (67Ga). The initial results of a prospective study of 72 scintigraphic examinations are reported. Analysis of the results reveals the value in using 67Ga to determine the stage of development of the lesion and consequently to adapt the treatment. Classical bone scintigraphy, whose value remains the early detection of signs compared to radiography, does not allow us to follow the course of the lesion over time. The need to combine scintigraphic techniques has already been recognised (Lisbona, Gaucher) but there has usually been sequential meaning, apart from the risk of false negatives (early osteitis), repeated visits by the patients over a period of time. The simultaneous use of 2 tracers, technically possible, avoids these problems and produces a rapid result (generally 6 hours after the injection).
