F-18-labeled fluorometaraminol, F-18-labeled fluorodopamine, and C-11- labeled hydroxyephedrine are myocardial PET tracers used for imaging:

Tc-99m-labeled leukocytes and Tc-99m sulfur colloid accumulate in the reticuloendothelial cells of the bone marrow. The distribution of marrow activity is similar in all of the following conditions with the exception of:

The size of the colloid particles is important in imaging the reticuloendothelial system. Particles smaller than 20 nm tend to accumulate in?

The primary route of excretion of Tc-99m hexakis 2-metoxy isobutyl isonitrile (Sestamibi) is:

Free Tc-99mO4− is an example of the radiochemical impurity in Tc-99m-tagged red blood cells (RBCs) preparation. During bleeding scan scintigraphy presence of free Tc-99m can be detected on:
