NUCLEAR MEDICINE UPDATED SCRIPTED EXAM
QUESTIONS AND SOLUTIONS GUARANTEE A+
✔✔How "In Vivo" works - ✔✔small tracer amounts are administered to the patient and
specimens of urine, blood, etc. is counted or measured for a wide variety of events
✔✔In Vitro - ✔✔Outside of the body or cell
✔✔"In Vitro" - ✔✔Used to study biologically important substances in the lood serum or
other body fluids.
✔✔Radionuclide administered for Bone Scan - ✔✔Tc99
✔✔Imaging for Bone Scan - ✔✔Begins 3 hours after administering Tc99 and takes 30
minutes
✔✔Areas of increased uptake for a Bone Scan - ✔✔Hot Spots that show tumors,
infection, fractures
✔✔Profusion - ✔✔Pumping of blood or fluid through an organ or tissue
✔✔Nuclear medicine scan that looks for profusion - ✔✔lung scan
✔✔Radionuclide administered for Lung Scan to view ventilation - ✔✔Xenon gas
administered through inhalation
✔✔Radionuclide administered for Lung Scan to view profusion - ✔✔Tc99mAA
administered by injection
✔✔Lung scans detect: - ✔✔pneumothorax and pneumonia
✔✔Radionuclide administered for Heart Scan - ✔✔Tc99
✔✔During what nuclear medicine scan are patients injected with labeled red blood cells
- ✔✔Heart Scan
✔✔Imaging for heart scan - ✔✔begins immediately after radionuclides are administered
and lasts for one hour
✔✔Radionuclide injected for Thyroid Scan - ✔✔Tc99
✔✔Radiocuclide administered orally for Thyroid Scan - ✔✔I-123
, ✔✔Scanning for Thyroid Scan - ✔✔Scanning begins 20 minutes after injection of Tc99
and begins 4-24 hours after oral nuclides are administered
✔✔Purpose of Thyroid Scan - ✔✔rule out cancer, screen for hyperthyroidism, goiter, a
solid nodule, thyroiditis
✔✔Radionuclide administered for Brain Scan - ✔✔Tc99 by injection
✔✔Scanning for Brain Scan - ✔✔begins 1 hour after injection
✔✔Purpose of Brain Scan - ✔✔Evaluate for stroke, alzheimers, epilepsy, parkinsons
disease
✔✔How does nuclear medicine detect cancer? - ✔✔Scans for metastasis
✔✔Therapeutic nuclear medicine for Cancer Detection - ✔✔Sentinel node and thyroid
ablation
✔✔sentinel node - ✔✔area or node that is adjacent to a tumor
✔✔throid ablation - ✔✔catheter goes in and will heat up and kill cancer cells
✔✔P.E.T. - ✔✔Positron Emission Tomography
✔✔Positron results in - ✔✔the production of 2 gamma rays
✔✔1900's - ✔✔clinical PET centers began
✔✔Commonly used isotopes for PET scans - ✔✔Carbon 11, Nitrogen 13, Oxygen 15,
Fluorine 18
✔✔Carbon 11 - ✔✔Radioactive isotope of carbon that decays 100% into Boron 11 by
positron emission
✔✔Half Life of Carbon 11 - ✔✔about 20 minutes
✔✔Nitrogen 13 - ✔✔Isotope of Nitrogen
✔✔Half Life of Nitrogen 13 - ✔✔about 10 minutes
✔✔Oxygen 15 - ✔✔Isotope of Oxygen
✔✔Half Life of Oxygen 15 - ✔✔about 2 minutes
