RIBS I.A. Flashcards
- Do Anterior ribs connect directly with sternum?
- What are the true ribs? how do they connect?
- What are false ribs? how do they connect?
- What are floating ribs?
- No. connect with costal cartilage that attaches to sternum
- 1-7 = TRUE RIBS, connect directly to sternum by own costocartilage
- 8-12 - FALSE RIBS, 8-10 connect to 7th Rib & 11 / 12 do not connect anteriorly (they are floating)
- Ribs 11 & 12 = FLOATING - do not connect anteriorly
- What are two ends of each rib?
- Where is head, neck, tubercle & angle of rib located?
- What end of rib is anatomically higher? by how much?
- On an image, the part of the rib most superior is the ________ end and the _________ end is more inferior.
- Posterior / Vertebral End
- Anterior / Sternal End
- Vertebral / Posterior End
- POSTERIOR 3-5in HIGHER THAN ANTERIOR
- posterior is higher, anterior is more inferior
AP or PA RIBS
- BILATERAL CR:
- UNILATERAL CR:
HOW DO YOU DETERMINE TO DO PA OR AP?
RESPIRATION FOR AP/PA RIBS?
BILATERAL: T7 (LEVEL OF INFERIOR SCAP. ANGLE) & MSP
UNILATERAL: 3-4in BELOW JUGULAR NOTCH, BTWN MSP & AFFECTED SIDE THORAX
AP FOR POSTERIOR RIBS
PA FOR ANTERIOR RIBS
ABOVE DIAPHRAGM = SUSPEND AFTER INSPIRATION
BELOW DIAPHRAGM = SUSPEND AFTER EXPIRATION
AP OR PA RIB GUIDELINES
- THORACIC VERTEBRAE-RIB ARTICULATION (VERTEBRAL END OF RIB) SEEN
- MEDIAL END OF CLAVICLE ADJACENT TO LATERAL EDGE OF SPINE
- ABOVE DIAPHRAGM RIBS 1-9 (inspiration)
- BELOW DIAPHRAGM RIBS 10-12 (expiration)
EVALUATE AP OR PA RIBS
- IMAGE 1: WHAT POSITION?
ANY ERRORS?
- IMAGE 2: WHAT POSITION?
ANY ERRORS?
IMAGE 1: AP PROJECTION- RPO ROTATION
- AP BC MARKER CORRECT ORIENTATION
- PATIENT ROTATED TO RIGHT
- R STERNAL END OF CLAVICLE AWAY FROM SPINE (SIDE CLOSER TO IR = GREATER DISTANCE)
IMAGE 2: PA PROJECTION, RAO ROTATION
- PA BC MARKER FLIPPED
- PATIENT ROTATED TO LEFT
- R STERNAL END OF CLAVICLE SUPERIMP. SPINE (SIDE CLOSER IR = SUPERIMP. BY SPINE)
EVALUATE AP OR PA PROJECTION
INCORRECT RESPIRATION
- TOO MANY RIBS BELOW DIAPHRAGM
- IMAGE WAS DONE ON EXPIRATION
- FIX BY TAKING IMAGE WITH SUSPENDED FULL INSPIRATION
AP OR PA OBLIQUE RIBS - GUIDELINES
- 45* OBLIQUE SHOWS AXILLARY PORTION OF RIBS NOT SEEN ON AP/PA
- AXILLARY PORTION OF RIBS OF INTEREST IN PROFILE & WITHOUT SELF SUPERIMP.
- AP OBLIQUES SHOW AFFECTED SIDE CLOSER IR
- PA OBLIQUES SHOW AFFECTED SIDE AWAY IR
- WHAT PROJECTION SHOULD BE OBTAINED ON PATIENT WITH RIGHT AXILLARY RIB INJURY ON POSTERIOR SIDE?
- FOR AXILLARY PORTION OF RIGHT RIBS =
- FOR AXILLARY PORTION OF L RIBS =
- AP OBLIQUE RPO
- RIGHT = RPO & LAO
- LEFT = LPO & RAO
EVALUATE AP OR PA OBLIQUE RIBS
- WHAT PROJECTION?
- ANY ERRORS?
- AP PROJECTION (BECAUSE MARKER CORRECT)
- RIGHT AXILLARY RIBS FORESHORTENED
- PATIENT INCORRECTLY POSITIONED
- PT ROTATED AWAY FROM AFFECTED SIDE IN LPO
( - PT SHOULD BE ROTATED TOWARD AFFECT SIDE IN RPO )
- Which of the following positions will best demonstrate the axillary portion of the left ribs?
a. AP. b. PA c. LPO d. LAO - Which two projections must be taken for an injury to the right anterior, upper ribs?
a. PA and LAO
b. PA and RAO
c. AP and RAO
d. AP and LPO - The bony thorax includes:
- C. LEFT POSTERIOR OBLIQUE
- A. PA & LAO
- 12 THORACIC RIBS, STERNUM & STERNUM
- The anterior ends of the ribs do not attach directly to the sternum.
True. False - Which of the following ribs is(are) classified
as a floating rib?
A. 1st rib. B. 2nd and 3rd ribs
C. 10th rib. D. 11th rib - A radiograph of an RAO projection of the ribs demonstrates the left axillary ribs are foreshortened, whereas the right side is elongated. Which of the following
is the most likely reason for this radiographic outcome?
a. The patient requires more rotation to the right.
b. An LAO was performed rather than the RAO position.
c. The technologist should have performed a PA projection to demonstrate the left axillary ribs, not an RAO.
d. CR angulation was incorrect.
- TRUE
- D. 11TH & 12TH = FLOATING
- B. An LAO was performed rather than the RAO position.
