Notes:

  • Previously used scan settings are above, but change settings to emphasize cartilage (fat is useful but not essential)
  • Scans:
    1. PD Sagittal
    2. PD Axial
    3. PD Coronal
    4. Static swallowing: sagittal view, 1-2 slices of swallowing
    5. Dynamic swallowing: scan showing close-up of epiglottis while swallowing (use fast scan rate)
  • Region to include:
    • vertical: between bottom of C7 and top of C2 spinal columns
    • depth: in front of Adam's apple to back of vertebrae
    • width: inside jaw, outside of arteries
  • Watch for reflection (fold-over) effect

Scan Set #8:

  • link: 2009-08-12_IanSoftPalate.zip
  • Ian (Control), 2000 Aug 12
  • Dual coil
  • Appliance, tongue at rest (not necessarily touching palate)
  • Imaging of soft palate in high resolution
