During The PA Axial (Stetcher Method) Scaphoid Projection, if the patient cannot perform ulnar deviation, the technologist could make what adjustment to perform this projection correctly?
angle the CR 20 degrees toward the elbow.
How should the technologist postion the patient for an Lateral Forearm Projection?
1. elbow flexed 90 degrees with hand and writ in true lateral position
2. humerus placed on same plan as forearm.
3. Epicondylar line perpendicular to IR
What will a Lateral Elbow Projection demonstrate?
1. distal humerus, proximal radius/ulna, elbow joint, trochlea and capitulum superimposed.
2. olecranon process seen in profile
3. fat pad sign, classic sign of elbow pathology.
To what degree is the Elbow flexed to demonstrate the Radial Head during the Axiolateral Projection (Coyle Method) projection of the elbow?
90 degrees
How should the technologist position the patient for an AP Humerus (non-trauma) Projection?
1. arm fully extended with hand supinated
2. epicondylar line parallel to the IR.
What does the Tangential Carpal Canal (tunnel) (gaynor-hart method) projection best demonstrate?
compression of the median nerve.
How should the technologist position the patient for an AP Elbow Projection?
1. hand is supinated with elbow completely extended
2. epicondylar line positioned parallel to IR
3. elbow in centered to the IR with the humerus places in the same plane as the forearm.
The AP Lateral Oblique Projection of the Elbow demonstrates ________?
the radial head, neck, and tuberosity with no superimposition over the ulna and capitulum.
To what degree is the Elbow flexed to demonstrate the Coronoid Process during the Axiolateral Projection (Coyle Method) projection of the elbow?
80 degrees
What does the AP Humerus (non-trauma) projection best demonstrate?
1. entire humerus
2. elbow and shoulder joints
3. greater tubercle in profile laterally.
How should the technologist postion the patient for an AP Forearm Projection?
1. hand is supinated, with elbow fully extended.
2.
What part of the Distal Humerus articulates with the Ulna?
the trochlea
The AP Medial Oblique Projection of the Elbow demonstrates ________?
the olecranon and coronoid processes of the proximal ulna.
What is the CR location for the Radial Head during the Axiolateral Projection (Coyle Method) projection of the elbow?
How should the technologist position the patient for a Lateral Humerus (non-trauma) Projection?
1. elbow flexed 90 degrees with the posterior aspect of hand placed on the hip
2. epicondylar line placed perpendicular to IR.
The Epicondylar line of the elbow, should be positioned _________ to the IR during an AP Forearm projection?
Parallel to the IR
what part of the Distal humerus articulates with the Radius?
the capitulum.
When would an AP Partial Flexion Elbow projection be performed?
if the patient cannot completely extend the elbow.
What is the CR location for the Coronoid process during the Axiolateral Projection (Coyle Method) projection of the elbow?
CR directed away from the shoulder at an angle of 45 degrees to the coronoid process, Cr enters elbow joint.
a Lateral Humerus (non-trauma) Projection best demonstrates ________?
lateral view of the entire humerus and lesser tubercle in profile medially.
Why is an AP Projection of the forearm preferred over the PA projection?
AP prevents overlap of the proximal radius over the ulna.
How should the technologist postion the patient for an Lateral Elbow Projection?
1. elbow flexed 90 degrees with hand and wrist in true lateral position
2. epicondylar line perpendicular to IR
3. humerus placed in the same place as forearm.
With the elbow in partial flexion, the part of interest, which is the ________ or the _______ is placed _______to the IR.
1. proximal forearm
2. distal humerus
3. parallel to the IR
The structure best demonstrated on the Axiolateral Projection (Coyle Method) projection of the elbow include ____________ and __________?
1. open elbow joint between radial head and capitulum
2. open elbow joint between coronoid process and trochlea.
How many degrees is the patient rotated during the Scapular Y-view of the Shoulder?
patient rotated RAO or LAO toward affected side so midcoronal plane forms a 45-60 degree angle to the IR.
