    Study Notes

    Radiography of the Cervical Spine

    • Standard cervical series:
      • AP Open Mouth View (APOM)
      • AP Lower Cervical View (APLC)
      • Lateral Cervical View

    AP Open Mouth View (APOM)

    • Focal film distance: 150cm
    • Tube tilt: 0°
    • Optimum kVp: 80 kVp
    • Patient position:
      • Stand with back against the erect bucky
      • Mid-sagittal plane of the body centered to the midline of the bucky
      • Head position: mid-sagittal plane perpendicular to the grid
      • Mouth open as far as possible
      • Lower edges of the upper incisors aligned with the base of the skull
    • Central Ray: in the midline, at the level of the atlas transverse process (C1 T.P)
    • Collimation: to just below the nose vertically and to the mastoids horizontally
    • Patient instructions: stop breathing and remain still
    • Structures shown: atlas and axis through the open mouth

    AP Lower Cervical View (APLC)

    • Focal film distance: 150cm
    • Tube tilt: 15° cephalad
    • Optimum kVp: 70 kVp
    • Patient position:
      • Stand with back against the erect bucky
      • Head immobilized with mid-sagittal plane perpendicular to the grid
      • Neck extended slightly so body of mandible is horizontal
    • Central Ray: vertically, between sterno-clavicular joints and the chin, in the midline

    Thoracic Spine

    • AP Thoracic View (AP-T)
      • Focal film distance: 150cm
      • Tube tilt: 0°
      • Optimum kVp: 80 kVp
      • Patient position: stand erect with back against the grid device
      • Central Ray: T6/T7 vertebral body
      • Collimation: vertically within vertical borders of image storage device, and 2cm either side of sternal edge
      • Patient instructions: suspend inspiration and remain still
      • Structures shown: vertebrae C7 to L1 in their AP orientation, proximal ends of the anterior rib, and medial borders of both lung fields

    Lateral Thoracic View

    • Focal film distance: 150cm
    • Tube tilt: 0°
    • Optimum kVp: 90 kVp
    • Patient position: stand erect with side of interest against the grid device in the true lateral position
    • Central Ray: vertically, as per AP Thoracic spine, and horizontally, posterior aspect of the kyphosis remains within collimation
    • Collimation: vertically within vertical borders of image storage device, and to include apex of curve posteriorly to the axillary fold anteriorly
    • Filter: 8mm stepped filter over the lower half of the collimation
    • Patient instructions: suspend inspiration and remain very still
    • Structures shown: all thoracic vertebrae in their lateral orientation

    Lumbar Spine

    • Standard chiropractic series:
      • A-P Lumbo-Pelvic View - erect
      • Lateral Lumbo Sacral View - erect
    • Additional views if indicated:
      • Oblique views
      • Spot views of SIJs, sacrum, L5/S1, Coccyx
      • Functional views
