The essential duty of a nuclear medicine technologist is the safe preparation and administration of radiopharmaceuticals. This role centers on verifying the patient, selecting the correct radiopharmaceutical and activity, and delivering the tracer through the appropriate route with sterile technique and accurate dosing. They also handle dose calibration, quality control, and radiation-safety measures to protect both patient and staff, and then proceed to acquire the imaging study as ordered. Interpreting imaging studies and prescribing radiopharmaceuticals are typically done by a physician. Reviewing imaging protocols and dosimetry records is more aligned with medical physics or dosimetry roles, and performing image-denoising algorithms falls under specialized post-processing or software development, not the core duties of an NM technologist.
