Nuclear Pharmacy

The fraction of total radioactivity present in the form of desired radiopharmaceutical is called:

In-111 and Tc-99m-labeled white blood cells (WBC) accumulation have been observed in all of the following conditions/sites EXCEPT:

Tc-99m methylene diphosphonate (MDP) is the most widely used bone imaging agent. Uptake of the tracer depends on all of the following EXCEPT

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

Tl-201 as thallous chloride at neutral pH with respect to biochemistry and physiology is considered to behave similarly to:

Ga-67 citrate and Tc-99m or In-111-labeled leukocyte imaging are wellestablished procedures for diagnosing a variety of inflammatory and infectious conditions. Normally healing surgical incisions will concentrate:

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:

Tc-99m-labeled red blood cells (Tc-99m RBC’s) and Tc-99m-labeled sulfur (Tc-99m sulfur colloid) can be used for the detection of gastrointestinal bleeding. Which of the following statements correctly describe their properties?

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

Thin layer chromatography (TLC) results were measured in the dose calibrator for a Tc-99m mebrofenin kit. If 3 mCi of free Tc-99m and 55 mCi of Tc-99m mebrofenin were measured in the dose calibrator, what is the percentage of radiopharmaceutical purity?
