TRACER FOR PET DIAGNOSIS FOR MALIGNANT TUMOR

摘要

PROBLEM TO BE SOLVED: To provide a tracer for PET diagnosis for malignant tumors using positron-emitting isotopes.SOLUTION: There is provided a porphyrin compound represented by the following formula, in which a porphyrin compound is complexed with an isotope of a positron-emitting metal such as positron-emitting zinc. A PET diagnosis using positron-emitting isotopes enables users to detect malignant tumors more effectively than before.
