Strontium‐87m and the Gamma Camera in the Study of Bone Metastases from Carcinoma of the Prostate

Summary Bone‐seeking isotopes can identify the site of osseous lesions in carcinoma of the prostate before radiography. The use of strontium‐87m and the role of gamma camera scintigraphy in a series of 71 cases of carcinoma of the prostate is discussed. The value of strontium‐87m scintigraphy is seen not only in its ability to detect some lesions earlier than radiological methods, but also as a parallel investigation which enhances overall diagnostic reliability. Repeated investigations are capable of providing some additional indications of the patient's response to treatment. The limitations of the scintigraphic method in repeated examinations are discussed.
