    X-ray/radiography/ roentenography
  8. A radiography is ordered by who and why?
    Ordered by the anesthesia provider for identification of lung abnormalities that may interfere with the exchange of gases during anesthesia.
  9. A portable x-ray is used for what reasons?
    • -Identify the location of abnormalities and foreign bodies.
    • -Located retained sponges, sharps, or instruments.
    • -Discover fluid or air within body cavities.
    • -Verify fluid/air within body cavities.
    • -Verifythe correct location for an operative procedure.
    • -Aid in bone realignment and prosthesis placement.
    • -Verifyplacement of indwelling catheters, tubes, and drains.
  10. An anterior/posterior (AP) radiographic views require that the film be placed where?
    Underneath the patient.
  11. What is a mammography used for?
    To locate tumors of the breast in their early stages.
  12. What is a myelography used for?
    Used to evaluate the spine for patients, it also can outline bone tissue.
  13. A fluroscopy is used for what, and what is it projected on to?
    Projects images of the body structures onto a monitor.
  14. What is an angiography used for?
    Assessing the cause & severity of peripheral vascular disease.
  15. Cardiac catherization permits the evaluation of what?
    Heart function, visualization of coronary arteries and cardiac chamber and the measurement of pressure within the cardiac chambers.
  16. What is a cholangiography used for?
    Used to outline calculi/ other obstruction under fluoroscopy.
  17. What does a CAT produce, and what is it better used for?
    X-raymachine that produces pictures of the body parts in slices. CTscanning is better for emergencies related to the brain because is is faster and better able to detect fresh bleeding.
  18. What does a pet scan help identify?
    How different areas of the brain function by highlighting chemical metabolic activity.
  19. What does a MRI produce and what is it good for?
    Produces pictures of the body parts in slices, but it can be taken from any direction. Good for imaging soft tissue.
  20. What is an ultrasound good for?
    Examination of the fetus.
  21. What does a echocardiography provide?
    Two dimensional image of the heart.
  22. What does a doppler monitor do?
    Measures blood flow that transmits the sound of moving RBC's to the transducer.
  23. What is a Doppler ultrasonography used for in the OR?
    To determine the patency of arterial anastomosis.
  24. A collections of isotopes in a certain area are referred to as a what? And what may it indicate?
    “hotspot” and may indicate the presence of a pathological condition.
  25. How does radiation therapy work?
    Radiation kills cells by interfering with their metabolic activity.
  26. What is a smear & brush biopsy?
    Fluid with cells that can be smeared & fixed on a microscope slide.
  27. What is a aspiration biopsy?
    Is the removal of fluid through a needle attached to a syringe.
