A human leucocyte elastase (HLE) inhibitor labelled with a detector moiety where the inhibitor is synthetic and has a molecular weight of less than 2000, is useful for the diagnostic imaging of sites of inflammation of infection in vivo, for labelling leucocytes in vitro, or for radiotherapy of rthritis. The HLE inhibitor is preferably a &bgr;-lactam or an azetidinone.
