Abstract
A diagnostic imaging agent useful for selection of a therapy for cancerous bone metastasis is provided, which comprises 99mTc(V)-dimercaptosuccinic acid as an effective ingredient. The agent is administered to a patient, and a scintigram is taken. This is especially useful for identifying osteoclastic type or mixed type bone metastasis or for identifying a disease in which the bone resorption due to osteoclast is enhanced, and thus allows a proper selection of therapies for such diseases.
