Answer:

(1) Trapezium (2) Trapezoid (3) Capitate (4) Hamate Question 2: LATERAL PROJECTION: FOREARM Patient Position

Answer:

Seat patient at end of table, with elbow flexed 90° Question 3: TRANSTHORACIC LATERAL PROJECTION: HUMERUS Minimum SID - IR size - KV

Answer:

Minimum SID-40 inches (102 cm) ?IR size-35 × 43 cm (14 × 17 inches),lengthwise

80-90 KV

Question 4: PA OBLIQUE PROJECTION: WRIST Part Position

Answer:

Center to IR. From pronated position, rotate wrist and hand laterally 45°. For stability, place a 45° block under thumb side of hand to support hand and wrist in a 45° oblique position or partially flex fingers to arch hand so that tips rest lightly on IR Question 5: PA PROJECTION: HAND Part Position

Answer:

Pronate hand with palmar surface in contact with IR; spread fingers slightly.?Align long axis of hand and forearm with long axis of IR.?Center hand and wrist to IR.Question 6: PA OBLIQUE PROJECTION-MEDIAL OR LATERAL ROTATION: FINGERS Patient Position

Answer:

Seat patient at end of table, with elbow flexed about 90° with hand and wrist resting on IR and fingers extended.Question 7: PA PROJECTION: HAND CR

Answer:

CR perpendicular to IR, directed to third MCp joint Question 8: POSTERIOR OBLIQUE POSITION-GLENOID CAVITY: SHOULDER ---GRASHEY

METHOD

Patient Position

Answer:

Perform radiograph with patient in an erect or supine position. (The erect position is usually less painful for patient, if condition allows.) Question 9: LATERAL PROJECTIONS: FINGERS CR

Answer:

CR perpendicular to IR, directed to pip joint

Question 10: A good criterion by which to evaluate a true lateral position of the elbow when it is flexed 90° is the appearance of the three concentric arcs. What are they?

Answer:

• & smallest arc is the trochlear sulcus. 2nd & intermediate arc appears double-lined as the outer ridges

or rounded edges of the capitulum and trochlea. The trochlear notch of the ulna appears as a 3rd arc of a true lateral elbow.Question 11: INFEROSUPERIOR AXIAL PROJECTION: SHOULDER -LAWRENCE METHOD Part Position

Answer:

Move patient toward the front edge of tabletop Place vertical cassette on table as close to neck as possible, and support w/ sandbags. Abduct arm 90° from body if possible;keep in ext rotation, palm up, with support under arm& hand.Question 12: LATERAL PROJECTION: WRIST Minimum SID - IR size - KV

Answer:

Minimum SID-40 inches (102 cm) ?IR size-24 × 30 cm (10 × 12 inches),lengthwise 65 TO 70 kV range Question 13: AP PROJECTION-INTERNAL ROTATION: SHOULDER Part Position

Answer:

Position patient to center scapulohumeral joint to center of IR. ? Abduct extended arm slightly; internally rotate arm (pronate hand) until epicondyles of distal humerus are perpendicular to IR.Question 14: The expanded distal end of the spine of the scapula that extends superiorly and posteriorly to the glenoid cavity (fossa).

Answer:

acromion

Question 15: TRANSTHORACIC LATERAL PROJECTION: HUMERUS CR

Answer:

Center mid-diaphysis of affected humerus and center of IR to CR as projected through thorax.

CR perpendicular to IR, directed through thorax to mid-diaphysis Question 16: LATERAL PROJECTION: ELBOW Part Position

Answer:

Center elbow joint to CR and to center of IR. Drop shoulder so that humerus and forearm are on same horizontal plane. Rotate hand and wrist into true lateral position, thumb side up.Question 17: LATERAL POSITION: THUMB Minimum SID - IR size - KV -

Answer:

Minimum SID- 40 inches (102 cm) IR size- 18 × 24 cm (8 × 10 inches), crosswise (multiple exposures) or lengthwise (single exposure) Digital systems-55 to 60 kV range

Question 18: Ulnar deviation - why is it used?

Answer:

The ulnar deviation movement of the wrist "opens up" and best demonstrates the carpals on the opposite side (the radial or lateral side) of the wrist- the scaphoid, trapezium, and trapezoid. Because the scaphoid is the most frequently fx carpal bone...Question 19: AP PROJECTION: ELBOW CR

Answer:

CR perpendicular to IR, directed to mid-elbow joint, which is approximately 2 cm (3/4 inch) distal to midpoint of a line between epicondyles Question 20: PA PROJECTION: FINGERS how can you tell if there is no rotation in a pa finger projection?

Answer:

No rotation of fingers is evidenced by symmetric appearance of both sides or concavities of the shafts of the phalanges and distal metacarpals.
