The invention relates to radiolabelled metallocene derivatives of the general formula
wherein Me is a metallocenyl group with a radioactive central atom,
R is a carbonyl or methylene group,
R, is a hydrogen atom or an alkyl group having 1-4 carbon atoms,
A is a carboxy group or a pharmaceutically acceptable salt thereof, or an alkoxycarbonyl or alkanoyl group having 2-5 carbon atoms, and
n is 1 - 4.
The invention also relates to radiodiagnostic compositions comprising said radiolabelled metallocene derivatives and to a method of performing a radiodiagnostic examination, in particular of examining the renal function.
