The dosage of technetium -99m for a lung scan is 20 uci/ kg of body weight. How many millicuries should be given to a 50.kg patient (1 mci=1000uci)
20 uci/kg x 50 kg = ?uci and convert to mci.

To calculate the dosage of technetium-99m for a 50 kg patient, we can use the given formula:
Dosage = 20 uCi/kg * body weight in kg
Substituting the values:
Dosage = 20 uCi/kg * 50 kg
Now, let's calculate the dosage:
Dosage = 1000 uCi/mCi * (20 uCi/kg * 50 kg)
Dosage = 1000 uCi/mCi * 1000 uCi
Therefore, the dosage of technetium-99m for a 50 kg patient is 1000 millicuries (mCi).
To determine the dosage of technetium-99m (Tc-99m) in millicuries (mCi) for a 50 kg patient, we can use the given information that the dosage is 20 uCi/kg of body weight.
First, let's calculate the total dosage in microcuries (uCi) for the patient's weight:
Dosage in uCi = Dosage per kg * Patient's weight
Dosage in uCi = 20 uCi/kg * 50 kg
Dosage in uCi = 1000 uCi
Since 1 mCi is equal to 1000 uCi, we can convert the dosage from uCi to mCi by dividing the total dosage in uCi by 1000:
Dosage in mCi = Dosage in uCi / 1000
Dosage in mCi = 1000 uCi / 1000
Dosage in mCi = 1 mCi
Therefore, for a 50 kg patient, the dosage of technetium-99m for a lung scan would be 1 mCi.
