  1. Health Sciences Chapter 23: Imaging Careers

  2. Medical Imaging • Radiologic Technologist • = Radiographer • Works under a radiologist • Job duties • Transferring and positioning patient • Ensure quality radiographs • Administer radiopaque materials • Use sterile technique • Maintain records • Good communication skills

  3. Work in hospitals, private facilities, physician offices • Some radiation hazard • 1-4 years of study • Certified

  4. Box 23-1 Imaging Careers

  5. Ape Mom

  6. Nuclear medicine • Radioisotope technologist or nuclear medicine technologist (NMT) • Prepares and administers radioactive compounds • Gamma ray emission are traced through body and timed • Blood volume, fat absorption, brain, lung, heart scans

  7. Medical sonographer • Ultrasound technologist • Produces two-dimensional images of internal organs using sound waves at high frequency • Specialize in obstetrics, abdominal or neurosonography • Echocardiography – heart and blood vessels • 2 year degree + certification

  8. Radiological physicist • Master’s or doctorate degree + 2-3 year postgraduate residency • Certified by American Board of Radiology • Works with application of ionizing radiation to medical diagnosis and therapy

  9. Dolphin Mom

  10. Medical dosimetrist • Work under medical physicist • Calculate and plan radiation doses to treat cancer

  11. Electrocardiograph technician • Work in radiology department • Attach electrode leads to patient to monitor heart • Vocational program • Specialize • Cardiac catheterization, echocardiography • Certification and registration

  12. Electroencephalographic technologist • Measure electrical activity of brain to aid in diagnosis • 1-2 year training • Certification

  13. Elephant Mom

  14. Content Instruction • Wilhelm Conrad Roentgen • Discovered x-rays in 1895 • Contrast agents developed by pharmacists to better visualize organs • 1950s – radioactive isotopes used • Radiographs – used in over 100 tests • Fluoroscopy – shows internal organs in real time

  15. Mammography • Radiographer with advanced certification • Now use digital mammography

  16. Computed tomography • Combines computers with radiographic procedures • CT scans provide cross-sectional views of body

  17. Giraffe Mom

  18. Positron emission tomography • Computers and radiographic technique to visualize the metabolic activities of the body • Gamma rays are produced in the body when a radioactive biochemical is inhaled or ingested • Computer produces colored images that are dependent on the amount of gamma rays • Radioactive material has short life span • Used to measure biochemical activity in brain, heart

  19. Magnetic resonance imaging • Produces high image resolution and tissue contrast • Forms picture by measuring magnetic field produced by ions in body cells • Radio frequencies are used to change the electronic pulses of the hydrogen nucleus in cells to one polarity • Speed of realignment when the radio frequencies are changed determines the type of image produced • No radiation exposure • Radiographer + special training

  20. Near infrared spectroscopy • Noninvasive measuring of cerebral functions • Infrared light that passes through brain can be detected by the spectrograph • Detect blood flow change in cerebral cortex

  21. Lion Mom

  22. Digital radiography • Reduces time and expense of processing x-rays • Uses more radiation

  23. Interventional radiology • Small tubes or catheters are inserted into blood vessels to correct abnormalities • Balloon angioplasty
