QUESTION 11 OF 30
What is the difference between PET and SPECT scans?
"SPECT scans use gamma-rays and PET scans use positrons."
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.
"The main difference between SPECT and PET scans is the type of radiotracers used."
