✔✔SPECT emitts - ✔✔single gamma ray
, ✔✔Purpose of SPECT - ✔✔cardiac profussion, brain, liver, tumor, bone studies
✔✔Geiger Counter/Geiger Meuller - ✔✔Detection and measuring instrument used to
locate lost radioactive sources and to measure amount left behind
✔✔Primary radiation survey instrument used in nuclear medicine - ✔✔Geiger Counter
✔✔Cutie Pie - ✔✔Inonizing chamber type survey meter used for high intensity sources
✔✔Rules for Radiation Safety in Nuclear Medicine - ✔✔Wear gloves, use lead or glass
shielding for radionuclides, elimiate spills or clean up immediately, wear extremity and
whold body monitors, do not eat or drint in the hot lab, use ALARA
✔✔Nuclear Medicine - ✔✔medical specialty that focuses on the use of radioactive
materials called radiopharmaceuticals for diagnosis, therapy, and medical research.
✔✔ Nuclear Medicine demonstrates: - ✔✔function
✔✔Nuclear Medicine is under the radiology umbrella because: - ✔✔radiation is used
