Ribs
PA
IR Size: 14x17 LW
SID: 40""
Page #'s: 1:474,202

Positioning:
  • A radiopaque spot marker is placed: on skin at area of pain
  • Erect preferred to: drop diaphragm & to see air & fluid levels
  • Hands on: hips & rotate shoulders forward (Moves scapula out of way)

CR Entrance & Angle:
  • _|_ to center of IR
  •

Collimation:
  •

Best to Determine:
  • Anterior ribs 1-9 with the posterior portions AD
  • If ribs 7-9 aren't well demonstrated, angle CR 10-15 caudad

Eval Criteria:
  • 1st - 9th ribs in their entirety, with posterior portions above diaphragm
  • 1st - 7th anterior ribs from both sides, in their entirety & above diaphragm
  • In a unilateral examination, ribs from opposite side possibly not included in entirety.
  • Ribs visible through lungs with sufficient contrast

AP (Above Diaphragm)
IR Size: 14x17 LW
SID: 40""
Page #'s: 1:476,204

Positioning:
  • A radiopaque spot marker is placed: on skin at area of pain
  • Erect preferred to: drop diaphragm & to see air & fluid levels
  • Hands: behind head and point elbows forward to draw scapula laterally

CR Entrance & Angle:
  • _|_ to center of IR
  •

Collimation:
  •

Best to Determine:
  • Posterior ribs 1-10 AD

Eval Criteria:
  • For ribs above the diaphragm, 1st - 10th posterior ribs from both sides in their entirety
  • Ribs visible through the lungs or abdomen
  • In a unilateral examination, ribs from opposite side possibly not included in entirety.

AP (Below Diaphragm)
IR Size: 14x17 CW
SID: 40""
Page #'s: 1:476,204

Positioning:
  • A radiopaque spot marker is placed: on skin at area of pain
  • Supine preferred: to raise diaphragm
  • Hands: in a comfortable position

CR Entrance & Angle:
  • _|_ to center of IR
  •

Collimation:
  •

Best to Determine:
  • Posterior ribs 8-12 BD

Eval Criteria:
  • For ribs below the diaphragm, 8th - 12th posterior ribs on both sides in their entirety
  • Ribs visible through the lungs or abdomen
  • In a unilateral examination, ribs from opposite side possibly not included in entirety.

AP Oblique (RPO/LPO)
IR Size: 14x17 LW
SID: 40""
Page #'s: 1:478,206

Positioning:
  • A radiopaque spot marker is placed: on skin at area of pain
  • Body rotated: 45° affected toward IR
  • Abduct arm of: affected (Hand behind head)

CR Entrance & Angle:
  • _|_ to center over affected to IR
  •

Collimation:
  • Collimate

Respiration:
  • Suspend on inspiration (AD) Expiration (BD)

Best to Determine:
  • Axillary portion & posterior ribs closest to IR

Eval Criteria:
  • Approximately twice as much distance between the vertebral column and the lateral border of the ribs on the affected side as is present on the unaffected side
  • Axillary portion of the ribs free of SI
  • 1st - 10th ribs visible above diaphragm for upper ribs
  • 8th - 12th ribs visible below diaphragm for lower ribs
  • Ribs visible through the lungs or abdomen according to region examined

PA Oblique (RAO/LAO)
IR Size: 14x17 LW
SID: 40""
Page #'s: 1:480,208

Positioning:
  • A radiopaque spot marker is placed: on skin at area of pain
  • Body rotated: 45° affected away from IR
  • Abduct arm of: affected (Hand on Bucky)

CR Entrance & Angle:
  • _|_ to center over affected to IR
  •

Collimation:
  • Collimate

Respiration:
  • Suspend on inspiration (AD) Expiration (BD)

Best to Determine:
  • Axillary portion & anterior ribs farthest from IR

Eval Criteria:
  • Approximately twice as much distance between the vertebral column and the lateral border of the ribs on the affected side as is present on the unaffected side
  • Axillary portion of the ribs free of SI
  • 1st - 10th ribs visible above diaphragm for upper ribs
  • 8th - 12th ribs visible below diaphragm for lower ribs
