Tests involving X-Ray, Contrast dyes, or Scans (non-radioactive)
Show Answers:

  1. Urography/Urogram
    Contrast material used

    X-Ray recording of the kidney and urinary tract

    Also called Intravenous Urography, Intravenous Pyelography (IVP), Retrograde Urography/Pyelography
  2. Small Bowel Follow Through
    Barium is swallowed

    X-Ray pictures are taken at increasing intrevals to follow the progress through the small intestine

    Used to identify obstructions or ulcers
  3. Barium Swallow
    (Upper GI Examination)
    Barrium sulfate is swallowed

    X-Ray of the esophagus, Duodenum, and Small intestine
  4. Ultrasonography/Ultrasound
    No contrast material used

    Sound waves directed into the body - capturing the echoes that bounce off organs

    Shows difference between fluid and solid mass

    Also called Sonography/Sonogram
  5. Myelography//Myelogram
    No contrast material used

    X-Ray of the spinal cord

    Largely replaced by MRI

    Used for detecting tumors or ruptured "slipped" disks
  6. Stereotactic Breast Biopsy
    A hollow needle is passed into a suspicious lesion with the help of mamopgraphic imaging
  7. Mammography/Mammogram
    No contrast material used

    X-Ray recording of the breast

    Used to detect breast cancer
  8. MRI
    (Magnetic Resonance Imaging)
    May be performed with or without contrast material

    Powerful magnetic field, radiofrequency waves, and computer used to produce images with specialized detail

    Commonly used for imaging tumors of the brain or spinal cord
  9. Barium Enema
    (Lower GI Examination)
    Barium sulfate inserted via enema into rectum and colon

    X-Ray images can detect tumors, obstructions, or irregularities
  10. Hysterosalpingography/
    Contrast material inserted through the vagina into the uterus and falopian tubes

    X-Ray recording obtained to detect blockage or tumors
  11. Fluoroscopy
    • No contrast material used
    • - may be enhanced with barium

    X-Ray images using a fluorescent screen

    Shows motion

    Fluoroscent substance emits a yellow/green light

    Used to guide insertion of catheters and direct organ biopsy
  12. ERCP
    (Endoscopic Retrograde Cholengiopancreatography)
    radiopaque contrast injected via tube placed through the mouth into the bile and pancreatic ducts

    X-Ray images obtained of the bile ducts, pancreas, and pancreatic duct
  13. Echocardiography/Echocardiogram
    No contrast material used

    High frequency sound waves through the chest into the heart

    Echos showing heart structure recorded

    Evaluates diseases of the valves and heart muscle
  14. Doppler Ultrasound
    No contrast material used

    Sound waves focused on blood vessels

    Measures blood flow as echos bounce off red blood cells

    Detects vessels that are blocked by clots or atherosclerosis
  15. CT Scan
    (Computed Tomography)
    Contrast material may be used

    X-Ray tube rotates around the body

    Processed by a computer to show body in "slices" (cross section)
  16. Cardiac Catheterization
    Contrast material used

    X-Ray shows heart structure

    Catheter is passed through a vein or artery into the heart to measure blood flow out of the heart, pressure, and O2 content
  17. Bone Density Scan
    No contrast material used

    Low energy X-Rays

    Reveal areas of bone deficiency (osteopenia) or thinning (osteoporosis)

    Also called Bone Densitometry or DEXA (Dual Energy X-Ray Absorpitometry)
  18. Coronary Arteriography
    Visualization of the arteries that travel across the outer surface of the heart
  19. Coronary Angiography
    A-Rays detect abnormalities in the vessels that bring blood to the heart
  20. Cerebral Angiography
    X-Ray images showing blood vessels of the brain
  21. Arteriography/Arteriogram
    Contrast substance used

    Injected into arteries

    X-Ray images taken

    Same as Angiography - only focuses on arteries and typically coronary arteries
  22. Angiography/Angiogram
    Contrast substance used injected into the blood vessels

    X-Ray images taken

    can detect blockage by clots, cholesterol plaques, tumors, or aneurysms
