Bony Thorax
Part 2
| Question | Answer |
|---|---|
| What position places the sternum in the heart shadow? | RAO |
| If the patient has a smaller thorax, they will require | More Rotation |
| PA Oblique Sternum (RAO) requires the patient oblique 15-20° in order to | Move the Spine out of the way |
| Why is a 30 inch SID recommended for a PA Oblique Sternum (RAO) | To blur the posterior ribs |
| PA Bilateral SC Joints CR Placement- | Enters the level of T2-T3 (jugular notch) at the MSP |
| How do we Avoid superimposition by mandible in a PA Bilateral SC Joints X-Ray? | Slightly elevate chin |
| Why do we use Suspended Expiration for PA Oblique Sternum? | Less person for the X-Ray to go through Blurs the ribs |
| PA Oblique SC Joint Patient Position- | 10 to 15-degree RAO/LAO |
| The ____________ is placed closer to the IR when performing a PA Oblique SC Joint | Affected Side |
| PA Oblique SC Joint CR Placement- | Enters at T2-T3 (jugular notch) 1-2 inches lateral of MSP on elevated side |
| What should you see on a properly positioned PA Oblique SC Joint? | Makes affected joint open |
| What should you see on a properly positioned PA Oblique SC Joint? | Other SC joint slightly superimposed with manubrium |
| A PA chest is included in a rib series to check for | Lung Damage |
| There are anterior and posterior | Upper Ribs |
| There are only posterior | Lower Ribs |
| Lateral Sternum Patient Position- | Rotate the patients shoulders posteriorly, place patients hands behind their back Center Sternum to Midline |
| Why do we use a 72 inch SID when performing a Lateral Sternum X-Ray? | To Compensate for large OID |
| Lateral Sternum CR Placement- | Enters lateral border of sternum at mid-sternum (T7) (midway between the jugular notch and xiphoid process) |
| Lateral Sternum Breathing Instructions | Suspended Inspiration |
| Lateral Sternum Breathing Instructions purpose? | Pushes the sternum outward |
| Bilateral & Unilateral AP Ribs are for? | Posterior Ribs |
| Bilateral & Unilateral PA Ribs are for? | Upper Anterior Ribs |
| Bilateral PA Ribs CR Placement- | Perpendicular through MSP; Enters at level of T7 |
| Unilateral PA Ribs CR Placement- | Perpendicular, halfway between MSP and lateral affected side; Enters at level of T7 |
| Why do we use Suspended Inspiration for Bilateral & Unilateral PA Ribs? | Create better contrast |
| Bilateral & Unilateral AP Upper Ribs Breathing Instructions | Suspend at end of full inspiration (Increases contrast) |
| Bilateral & Unilateral AP Lower Ribs Breathing Instructions | Suspend at full expiration (Less person to go through) |
| Bilateral & Unilateral AP Lower Ribs CR Placement- | Place bottom of IR at crest and center CR to IR |
| What position would we use to view the Right anterior ribs? | LAO |
| AP Oblique Ribs: LPO/RPO Patient Position- | 45-degree posterior oblique, affected side toward the board Abduct and elevate arm of affected side |
| AP Oblique Ribs: LPO/RPO CR Position- | Perpendicular, entering affected side halfway between MSP and lateral surface of body |
| PA Oblique Sternum (RAO) CR Placement- | Perpendicular, enter T7, 1 in lateral to MSP on elevated side |
