FULL TEXT  


Bone scin­tig­ra­phy con­tin­ues to be one of the ­most com­mon­ly per­formed pro­ce­dures in nucle­ar med­i­cine. The radio­nu­clide ­bone ­scan ­remains an excel­lent modal­ity to ­detect met­a­stat­ic dis­ease in ­patients suf­fer­ing ­from pri­mary malig­nan­cies. This arti­cle ­reviews a num­ber of ­aspects of ­bone scin­tig­ra­phy ­such as ­bone phys­iol­o­gy, radio­phar­ma­ceu­ti­cals and ­uptake mech­a­nisms. As 99mTc ­labelled bis(di)phos­pho­nates are the ­most fre­quent­ly ­used ­this ­articke is cen­tred ­around ­these imag­ing ­agents. In addi­tion to diag­nos­tic ­bone scin­tig­ra­phy the use of var­i­ous ­bone seek­ing ­agents has ­been extend­ed to the pal­li­a­tive treat­ment of ­bone metas­ta­ses. In ­this con­text the radio­bi­o­log­i­cal char­ac­ter­is­tics of var­i­ous radio­nu­clides as 89Sr, 32P, 153Sm, 186Re and 117Sn is elu­ci­dat­ed. In addi­tion, the clin­i­cal effi­ca­cy for ­pain kill­ing of ­these radio­nu­clides is elu­ci­dat­ed on the ­basis of the radi­a­tion prop­er­ties of ­these ­agents. It is con­clud­ed ­that 89Sr and 186Re are pres­ent­ly the radio­nu­clides of ­choice. The lat­ter ­agent has a ­slight advan­tage as its imag­ing pho­tons ­enable indi­vid­u­al dosim­e­try, result­ing in an opti­mosed appli­ca­tion ­scheme.
