How many microcuries of iodine-131 are needed for a 64.0 rm kg patient with hyperthyroidism?

For patients with hyperthyroidism, the typical dose of iodine-131 is 30 microcuries per gram of thyroid tissue.

The average adult thyroid gland weighs about 25 grams. So, for a 64 kg patient, the estimated weight of the thyroid gland would be:

25 grams * (64 kg / 70 kg) = 23.1 grams

Therefore, the recommended dosage of iodine-131 for this patient would be:

30 microcuries / gram * 23.1 grams = 693 microcuries.

It's important to note that the actual dosage may vary depending on the individual patient's condition and the doctor's assessment. The dosage should be determined by a qualified medical professional based on the patient's specific needs.
