  1. T of F: nuclear medication detects functional (vs. anatomical) properties of human tissue
    True
  2. Common radionucleotide used in nucelar medicine
    Tc-99m
  3. What is a radionucleotide combined with to give it specificity?
    Pharmaceutical
  4. 2 cameras used in nuclear medicine
    • SPECT camera
    • PET camera
  5. SPECT
    Single photon emission computer tomography
  6. Radioactivity involved in PET camera
    Radioactive atom emits 2 photons in opposite directions
  7. PET
    Positron Emission Tomography
  8. Radioactive substance used in nuclear thyroid scan
    Radioactive iodine (taken up by the thryoid)
  9. Thyroid nodules: cold vs. hot
    • Cold: iodine not taken up as much - 1 of 4 malighant
    • Hot: More iodine taken up - indicates hyperfunctioning, usually BENIGN (Grave's disease)
  10. Pulmonary embolism: ventilation vs. perfusion
    • Normal ventilation
    • Decreased perfusion
  11. Most common molecule used in PET/CTs
    • F-FDG
    • Fluorogioxyglucose
    • Is radioactive glucose
  12. Warburg effect
    Malignant cells show increased glucose metabolism
  13. Use of x-rays to look at arteries
    Angiography (must use dye in X-rays - not the case in MRI)
  14. CT
    Computed tomography
  15. Combination of special x-ray equipment with sophisticated computers to produce multiple images
    CT
  16. Technique that uses powerful magnetic fields, radio frequency pulses and a computer
    MRI
  17. Subluxation vs. dissociation
    • Subluxation: part of articular surface touching
    • Dislocation: articular surface NOT touching AT ALL
  18. What does a T2 weighted image bring out?
    Edema or H2O
  19. Condition associated with deep sulcus sign
    Pneumothorax
  20. Pneumothorax associated with contralateral mediastinal shift
    Tension pneumothroax
  21. Riggler's sign is associated with what condition?
    Pneumoperitoneum (air seen inside and outside of bowel wall)
  22. Severe sepsis with persistent hypotension despite adequate fluid resuscitation
    Septic shock
  23. Mortality rate fr septic shock
    40-70%
  24. Possible treatments for septic shock
    • Activated protein C
    • Early goal direct therapy
  25. Medication for septic shock
    • Dopamine
    • *****NE
  26. What measure identifies patients with hypoperfusion?
    Serum lactate
