Patient preparation for infection imaging used tagged white blood cells include:
-fasting for at least 4 hr with a blood glucose level below 120 mg/mL
-smoking cessation for at least 24 hr
-discontinuation of certain medication

surface of the patients neck and the standard counts 20 cm from the surface of the neck
phantom. What is the effect on the thyroid uptake value calculated from this data?
-the uptake value will be accurate
-the uptake value will be falsely decreased
-the uptake value will be falsely increased
-the results are unpredictable - The uptake value will be falsely increased
