21. What is the difference between PET and SPECT scans?
How to Answer
As a Nuclear Medicine Technologist, you know that PET and SPECT scans are nuclear medicine imaging techniques which provide metabolic and functional information unlike CT and MRI. Tell the interviewer that the SPECT scan is a 3D scan that shows the distribution of radioactive tracer molecules and gamma-ray emissions that have been introduced into the patient's body. Unlike a SPECT scan measuring gamma-rays a PET scan measures positrons.
