Imaging technique:
Radiography (X-rays, CT-scans)
  • Most common form of medical imaging (X-rays)
  • Uses electromagnetic (ionizing) radiation
  • Structures that absorb the high energy beams will appear in white: bones and prosthetics (dense structures and high atomic number)
  • Relatively inexpensive
  • CT-scan = computes tomography: several high-resolution cross-sectional images are taken to create a more 3D view of the body parts (position and shape) -> tumours, blood clots, infections
Report
Imaging technique:
MRI (magnetic resonance imaging)
  • This technology uses magnets and radiowaves to produce an image of the soft tissues of the body: tumours, organ damage
  • No radiation (less risk than CT-scan)
  • High-resolution images
  • Based on movement of protons in the body
Report
Imaging technique:
Nuclear Medicine (e.g. PET-scans)
  • Uses radioactive tracers (isotopes) bonded to a carrier molecule (e.g. Modified glucose)
  • Administration: intravenous, oral, inhalation
  • Produces 3D image through detection of photons
  • Can view all types of tissues
  • Usually for digestive or circulatory system, also for lungs (e.g. Pulmonary embolism)
Report
Imaging technique:
Ultrasound (echography)
  • High frequency sound waves
  • Does not use radiation: safe!
  • Hard tissues (white) and soft tissues (grey) can be viewed using an ultrasound machine: diagnose diseases, monitor a fetus during fetal development, viewing blood flow through the body, and viewing the heart
  • Can capture movement (live images)
  • Small portable machines
