| A. head B. neck C. tubercle D. angle E. body | |
| A. sternal extremity of clavicle B. sternoclavicular joints C. manubrium D. body E. xiphoid tip | |
| F. costotransverse joint -plane/gliding -diarthrodial G. costovertebral joint -plane/gliding -diarthrodial | |
| A. T1 B. C7 C. 5th rib D. 8th rib E. 9th rib | |
| Hypersthenic Thorax requires less obliquity | |
| Sthenic Thorax requires more obliquity | |
| The xiphoid process does not become completely ossified until the age of...... | 40 |
| The sternal angle corresponds with the vertebral level of ____ | T4-T5 |
| The inside margin of the rib, containing the blood vessels and nerves, is called the _________ | Costal Groove |
| The sternoclavicular joint of the first rib is classified as _________ | Synarthrodial |
| What are some important technical factors for a sternum exam? | -orthostatic breathing technique (2-3sec) -40 SID, 65-80kVp -pt must be obliqued to see the sternum -CR perpendicular 1 in to the left of the midline |
| What are some technical factors involved in a rib study? | - RAO (LPO) elongates the left posterior and axillary ribs - LAO (RPO) elongates the right posterior and axillary ribs -area of interest must be closest to the IR -mark the site of injury |
| RAO for the sternum projects the ____ over the shadow of the ____ | STERNUM HEART |
| If the sternum is superimposed by the spine, what should you do? | Increase obliquity |
| TRUE OR FALSE? If you decrease mA and increase Sec for a breathing technique, your technique will stay the same, you will just be increasing the exposure time. | TRUE: mA Sec = 2 1 3 1 2 3 |
| Expose on _____ if pt is standing Expose on _____ if pt is recumbent | INSPIRATION EXPIRATION |
| Why is the lateral sternum projected at 72 SID when the RAO is projected at 40 SID? | increasing the SID will decrease the OID of the sternum in relation to the IR |
| What makes a sternum x-ray repeatable? | not seeing the entire sternum rotation exposure factors no markers |
| What makes a rib study x-ray repeatable? | not seeing all the ribs poor inspiration/expiration exposure factors markers |
| Why are the SC joints projected in PA? | Less OID with PA |
| What makes a PA SC joint projection repeatable? | rotation exposure factors done AP instead of PA |
| Which vertebral level corresponds with the SC joints? | T2-T3 palpate the clavicle vs. manubrium |
| For oblique SC joints, you perform a ____ for the right side, and a ____ for the left side | RAO LAO |
| When viewing oblique SC joint x-rays, how should the joint space appear? | OPEN and shifted away from the spine |
| What are the 2 views for the SC joints? | PA RAO (LPO) LAO (RPO) |
| What are the 2 views for the sternum? | RAO (LPO) Lateral |
| What are the views of the ribs for a routine study? | AP or PA above AND below diaphragm (bilateral) Unilateral (AP or PA) Axillary (anterior or posterior oblique) |
| TRUE OR FALSE The ideal general position for a study of ribs below the diaphragm is recumbent. | TRUE |
| RAO (LPO) elongates the _____ ribs | LEFT |
| LAO (RPO) elongates the ______ ribs | RIGHT |
| RAO will show the same image as ____ | LPO |
| RPO will show the same image as ____ | LAO |
| TRUE OR FALSE In general, you want the spine rotated toward the affected side. | FALSE you want the spine rotated away from the affected side - this will place the affected side to the IR |
| A patient enters the ER with a Fx rib and possible hemothorax/pneumothorax; which projection/position will be ordered along with the routine rib study? | PA and Lateral CXR |
| Which ribs are true? | 1-7 |
| Which ribs are false? | 8-10 |
| Which ribs are floating? | 11-12 |
| Which projection requires the patient to be erect and obliqued 15-20 degrees? | RAO sternum |
| Which projection requires the patient to be recumbent and obliqued 10-15 degrees? | RAO SC Joint |
| Which projection requires the patient to be erect with 45 degree obliquity? | RAO Ribs |
| Which projection requires the patient to be recumbent with 45 degree obliquity? | LPO Ribs |
| Which portion of the spine is level with the jugular notch? | T2-3 |
| Which portion of the spine is level with the sternal angle? | T4-5 |
| Which portion of the spine is level with the xiphoid tip? | T9-10 |
| Which portion of the spine is level with the inferior costal margin? | L2-3 |
| There is only one projection of the thorax that has 72 SID, the rest are all at 40 SID - Which projection is 72 SID? | Lateral Sternum |
| Where is the image receptor placed for a lateral sternum? | 1 1/2 in above jugular notch |
| TRUE OR FALSE it is recommended practice to reduce SID to less than 40 SID for RAO sternum to magnify the sternum | FALSE never decrease SID below 40 SID - this is a patient radiation dose red flag! |
| anterior obliques will demonstrate | the opposite side |
| posterior obliques will demonstrate | the same side |
| A patient enters the ER with pain and injury to the right side of the ribs, which projection/position should you perform? | RPO it will elongate the posterior right ribs *RAO will elongate the left ribs* |
