What condition should Ga-67 images be performed for early detection after injection?

Gallium-67 imaging is particularly useful for identifying osteomyelitis due to its ability to localize areas of inflammation and infection. When Ga-67 is injected, it is taken up by macrophages and other inflammatory cells, which accumulate in infected or inflamed areas. This characteristic makes it an effective diagnostic tool for conditions like osteomyelitis, as it can reveal the presence of infection in bone earlier than some other imaging modalities.

In contrast, acute myocardial infarction primarily requires myocardial perfusion studies and does not benefit from Ga-67 imaging in the same capacity. Renal failure and liver cirrhosis are not indications for Gallium-67 scans; these conditions are generally assessed with different imaging techniques or other functional tests that provide more relevant information regarding their progression or complications. Thus, osteomyelitis stands out as the correct reason for utilizing Ga-67 imaging after injection.
