The only nuclear medicine procedure i know for imaging the pituitary gland, a rather exotic one, ist I-123 IBZM (iodobenzamide) SPECT in prolactinomas. in general, pituitary diseases are investigated with MRI. but Tc-99m MIBI can visualise the parathyroid glands.
Excessive use of magnesium supplements can be toxic. The upper limit -- the highest dose a person can take -- of magnesium supplements is: 65 mg/day for children ages 1-3. 110 mg/day for children ages 4-8. 350 mg/day for adults and children ages 9 and up.
This 4-week study looked at the blood levels of both free and total testosterone in 3 groups of men. Group 1 was a group of sedentary men who took magnesium supplements (10mg per kg of body weight per day). So for example, an 80 kg male would take 800 mg of magnesium per day for 4 weeks. He was âsedentaryâ, which means he basically just took the magnesium supplement each day and did nothing else. Not bad. Group 2 was a group of tae kwon do athletes.
