Which of the following property of radiation is principally used in the treatment of tumors?

Iodine-131 is considered to be the treatment of choice in many patients with Graves’ disease. The most common side effect of radioactive iodine (RAI) treatment is:

Localizing metastatic disease in thyroid cancer patients with F-18 fluorodeoxyglucose (FDG) PET imaging is the primary clinical indication if:

To reduce radiation exposure to the patient undergoing radioactive iodine (RAI) treatment, all of the following recommendations will be helpful EXCEPT:

The general pretreatment requirements for adult qualifying for therapy with I-131 metaiodobenzylguanidine (MIBG) include the following EXCEPT:

F-18 is a cyclotron-produced radioisotope with a half-life approximately of:

All of the following cellular mechanisms are responsible for malignant cells increased F-18 fluorodeoxyglucose accumulation EXCEPT:

What is the usual range of a 24 hr radioiodine uptake in hyperthyroid patients diagnosed with subacute thyroiditis?

What is the predominant toxicity of radioisotopes used in the treatment of bone metastases?

Brain stimulations, such as motor stimulations, result in hypermetabolism in the area of the brain that is impacted by that stimulation and on PET FDG images this area will light up. If the patient exercises his or her left arm 30 min before the procedure which area of the brain will show increased radiotracer uptake during the PET FDG scan?
