Father of Nuclear Medicine - ANSWER-Georg de Hevesy
Fluorine 18 - ANSWER-Most common isotope used in PET scans of the brain
Fluorine 18 has a useful half life because - ANSWER-its lowest positron energy creates
the sharpest images and highest resolution PET
Gamma camera - ANSWER-main type of device to receive the radiation emitted from
patient for imaging
Geiger Counter/Geiger Meuller - ANSWER-Detection and measuring instrument used to
locate lost radioactive sources and to measure amount left behind
Half Life of Carbon 11 - ANSWER-about 20 minutes

and specimens of urine, blood, etc. is counted or measured for a wide variety of events
How does nuclear medicine detect cancer? - ANSWER-Scans for metastasis
Imaging for Bone Scan - ANSWER-Begins 3 hours after administering Tc99 and takes
30 minutes
Imaging for heart scan - ANSWER-begins immediately after radionuclides are
administered and lasts for one hour
In Vitro - ANSWER-Outside of the body or cell
In Vivo - ANSWER-inside the body or cell
Lung scans detect: - ANSWER-pneumothorax and pneumonia
