Bone tumor imaging by scintigraphy of the skeleton, marrow reticuloendothelial system, and the proliferative tissue

Paralleled clinical studies of radioisotopic imaging or tumor metastases in the bone were undertaken with Tc99m pyrophosphate, Ga67 citrate, and Tc99m sulfur colloid. All three were capable of anticipating the bone roentgenograms. A critical analysis suggested that positive delineation with Ga67 citrate would sometimes be superior to the others. This deserves further investigation. Clinically the combined use of Tc99m pyrophosphate with Ga67 for the chest areas and extremties or with Tc99m colloid for the pelvic and abdominal areas would be more frutiful in early detection and exact localization of bone metastases.
