Show Answers:

  1. CT
    computed tomography, beams x-rays at multiple angles through a section of the patient's body
  2. MRI
    magnetic resonance imaging, magnetic field and radio waves produce sagittal, coronal, and axial images of the body
  3. PET
    positron emission tomography, positron-emitting radiactive substances given intravenously create a cross-sectional image of cellular metabolism based on local concentration of the radioactive substance
  4. US
    ultrasonography, diagnostic technique that projects and retrieves high-frequency sound waves as they echo off parts of the body
  5. SPECT
    single photon emission computed tomography, radioactive tracer is injected intravenously and a computer reconstructs a 3D image based on a composite of many views
  6. fluoroscopy
    an x-ray procedure that makes it possible to see internal organs in motion
  7. in vitro
    process, test, or procedure is performed, measured, or observed outside a living organism, often in a test tube
  8. in vivo
    process, test or procedure is performed, measured, or observed within a living organism
  9. radiolucent
    permitting the passage of x-rays, radiolucent structures appear black on x-ray film
  10. radiopaque
    obstructing the passage of x-rays, radiopaque structures appear while on the x-ray film
  11. bone scan
    phosphate compound is taken up preferentially by bone and the skeleton is imaged in 2 or 3 hours, the scan detects infection, inflammation, or tumors involving the skeleton, which appear as areas of high uptake on the scan
  12. contrast studies
    radiopaque materials (contrast media) are injected to obtain contrast with surrounding tissue when shown on the x-ray film
  13. half-life
    time required for a radioactive substance to lose half its radioactivity by disintegration
  14. interventional radiology
    therapeutic or diagnostic procedures performed by a radiologist
  15. ionization
    transformation of electrically neutral substances into electrically charged particles
  16. mammography
    uses low dose x-rays ot visualize breat tissue
  17. nuclear medicine
    medical specialty that studies the uses of radioactive substances in diagnosis of disease
  18. radioimmunoassay
    test combines radioactive chemicals and antibodies to detect minute quantites of substances in a patient's blood
  19. radiology
    medical specialty concerned with the study of x-rays and their use in the diagnosis of disease, including other forms of energy, such as ultrasound and magnetic waves
  20. radiologist
    a physician who specializes in the practice of diagnostic radiology
  21. radiologic technician
    allied health care professionals who work with physicians in the fields of radiology and nuclear medicine
  22. sonogram
    a record on ultrasound procedures
  23. tracer studies
    radionuclides are used as tags or labels, attached to chemicals and followed as they travel through the body
  24. transducer
    handheld device that sends and receives ultrasound signals
  25. ultrasonography
    diagnostic technique that projects and retrieves high-frequency sound waves as they echo off parts of the body
  26. x-ray positioning
    different views of x-ray
  27. eversion
    turning outward
  28. inversion
    turning inward
  29. lateral decubitus
    lying down on the side
  30. recumbent
    lying down(may be prone or supine)
