| For the two AP Elbow partial flex projections, if the patient cannot extend elbow, and it remains at almost 90 degrees, what should you do? | angle the CR 10-15 degrees into the elbow |
| AP Elbow Partial Flex with humerus parallel (patient cannot fully extend elbow - 2 projections) | 60-75 kV 40 SID 14x17 IR nongrid CR @ mid-elbow MUST SEE distal humerus |

| Which elbow projection/position best demonstrates the coronoid process? | AP Oblique - medial rotation |
| Which fat pad of the elbow will only appear on x-ray if there's a joint pathologic process? | Posterior Fat Pad |
| Why does the elbow need to be in 90 degree flexion to determine whether the posterior fat pad is visible or not? | When elbow is flexed more or less than 90 degrees it pushes the fat pad into different position, it can show up on x-ray then when there's no pathologic issue |

| What is the only difference among the four radial head lateral projections of the elbow? | the rotational positioning of the wrist exposure factors stay the same |
| Why would you perform any of the 4, or all 4 of the radial head lateral views? | To view occult Fx's of the radial head or neck |
| Some sites use this projection as part of their routine elbow series. Which one is it? | "Radial Head View" Trauma Axial Lateral - Coyle Method - Radial Head |
| According to the textbook, the CR is perpendicular to the IR and humerus, directed to a point midway between epicondyles for ______ when the elbow is in acute flexion. | Acute Flexion of Distal Humerus |
| How many exposures are required for the AP Acute Flexion series? | 2 projections: Acute Flexion of Distal Humerus Acute Flexion of Proximal Forearm |

| Which oblique elbow projection best demonstrates the radial head and neck? | AP Oblique projection - Lateral rotation |
| Which elbow projection best demonstrates pathologic issues such as osteomyelitis and arthritis? | Lateral Elbow projection (lateromedial) |
| According to the textbook, the CR perpendicular to the forearm (angling CR as needed), directed to a point 2 in proximal or superior to the olecranon process, with the elbow in acute flexion, indicates which projection/position? | Acute Flexion Elbow - Proximal Forearm |
| Which trauma axial elbow projection has the elbow flexed 80 degrees? And what specific anatomy is this projection demonstrating? Which way is the tube angled for this projection? | Trauma Axial Lateral - Coronoid Process 45 degrees away from the elbow |
