What are the two routine projections for the Forearm series? | AP projection Lateral (lateromedial) projection |
AP projection Collimation? patient positioning? IR placement? Central Ray? Shield | 14x17 Seated in a position to place the entire limb in one plane Supinate the hand and extend elbow onto IR so that the long axis of IR is parallel with the forearm CR is perpendicular to the midpoint of the forearm Shield is required |
Lateral (lateromedial) projection Collimation? patient positioning? IR placement? Central Ray? Shield | 14x17 Seated in a position to place the entire limb in one plane Flex elbow 90 degrees, center forearm on IR and parallel with the long axis of the forearm CR is perpendicular to the midpoint of the forearm Shield is required |
What are the three routine projections for the Elbow series? | AP projection Lateral (lateromedial) projection AP Oblique (lateral position) projection |
AP projection Collimation? patient positioning? IR placement? Central Ray? Shield | 10x12 Seated in a position to place the entire limb in one plane Extend elbow and supinate the hand. Center IR to the elbow joint. CR perpendicular to the elbow joint Shield is required |
Lateral (lateromedial) projection Collimation? patient positioning? IR placement? Central Ray? Shield | 10x12 Seated at end of table so the humerus and elbow joint are in the same plane Center the IR to the Elbow joint CR perpendicular to the elbow joint Shield is required |
AP Oblique (Lateral position) projection Collimation? patient positioning? IR placement? Central Ray? Shield | 10x12 Seated at the end of the table with arm extended Center the midpoint of the IR to the elbow joint CR perpendicular to the elbow joint Shield is required |
For the AP projection of the forearm, how should the elbow be positioned? | Fully extended |
If the hand is pronated for the AP projection of the forearm, what will the image demonstrate? | Radius and Ulna crossed over each other |
For the lateral projection of the forearm, how should the elbow be positioned? | Flexed 90 degrees |
True or False. The hand should be pronated for the lateral projection. | False |
For the AP projection of the elbow, why should the hand be positioned with the palm facing up? | To prevent rotation of the bones of the forearm |
For the lateral projection of the elbow, how should the hand be adjusted? | Lateral with the thumb side up |
How many degrees of flexion of the elbow are necessary for the lateral projection? | 90 degrees |
How should the humeral epicondyles appear in the image of the lateral projection of the elbow? | Superimposed |
Which AP oblique projection positioning movement (medial rotation or lateral rotation) requires the hand to be pronated? | Medial rotation |
