The invention provides MRI contrast agents which provide a high sensitivity and which have an optimised body retention time. These agents enable the mapping of the local pH, temperature, oxygen concentration or other metabolites in a patient's body by the use of Chemical Exchange Saturation Transfer (CEST). Particularly pH and temperature mapping are useful for the detection of small cancer lesions and localised inflammation respectively.

A cancer targeting composition, kit, and method for treatment of cancer cells overexpressing somatostatin receptors is disclosed. The composition includes a radioisotope, a chelator, and a targeting moiety. The chelator includes a nitrogen ring structure including a tetraazacyclododecane, a triazacyclononane, and/or a tetraazabicyclo [6.6.2] hexadecane derivative. The targeting moiety includes a somatostatin receptor targeting peptide. The somatostatin receptor targeting peptide includes an octreotide derivative. The targeting moiety is chelated to the radioisotope by the chelator whereby the cancer cells are targeted for elimination.
