On the date described [07/18/08] an outpatient reported to the Nuclear Medicine Department for a Nuclear Medicine whole body bone scan. The technician drew up and injected the patient with 24.3 mCi mTc99 Sestamibi, I.V. instead of the proper cold kit which would have been Medronate. The error was not discovered until the patient returned
