Protocol Structure

Head Routine

  • Topogram
  • Non contrast
  • Contrast
  • Head IV

Topogram

Topogram should be cover from vertex of skull to C1


Non Contrast

Adjust the ROI angle to align with Base of Skull

To reduce or avoid ocular lens exposure, the scan angle should be parallel to a line created by the supraorbital ridge and the inner table of the posterior margin of the foramen magnum
