Position: Scaphoid PA Ulnar Deviation The PA ulnar deviation view elongates the scaphoid and reduces foreshortening. It is essential for detecting scaphoid fractures. Ulnar deviation shifts the carpals to improve visualization. This projection is a standard special view on ARRT exams. It is widely used in wrist trauma imaging.
Position: Forearm AP The AP forearm projection evaluates the radius and ulna in anatomical position. The hand is supinated to prevent crossover of the bones. This projection is essential for fracture assessment. Proper centering includes both wrist and elbow joints. It is a foundational ARRT extremity competency.
Position: Forearm Lateral The lateral forearm projection demonstrates the radius and ulna superimposed. The elbow is flexed 90 degrees for proper positioning. This view is essential for evaluating fractures and soft tissue injuries. It complements the AP projection. It is a standard ARRT requirement.
Position: Elbow AP The AP elbow projection evaluates the distal humerus and proximal forearm. The arm is fully extended with the hand supinated. This projection assesses joint spaces and fractures. Proper centering ensures accurate visualization of the elbow anatomy. It is a core ARRT competency.
Position: Elbow Lateral The lateral elbow projection demonstrates the olecranon process and joint alignment. The elbow is flexed 90 degrees with the thumb up. This projection is essential for evaluating effusion and fractures. It is frequently tested on ARRT exams. Proper positioning prevents rotation artifacts.
Position: Elbow Oblique Medial The medial oblique elbow projection demonstrates the coronoid process. The arm is pronated to rotate the elbow medially. This view is essential for fracture evaluation. It complements the lateral and AP projections. It is a recognized ARRT special projection.
Position: Elbow Oblique Lateral The lateral oblique elbow projection demonstrates the radial head and neck. The arm is externally rotated to isolate the radial structures. This projection is essential for trauma assessment. It is a standard ARRT competency. Proper positioning prevents superimposition.
Position: Humerus AP The AP humerus projection evaluates the entire humerus in anatomical position. The hand is supinated to prevent rotation. This projection includes both shoulder and elbow joints. It is essential for fracture and lesion assessment. It is a core ARRT requirement.
Position: Humerus Lateral The lateral humerus projection demonstrates the humerus in profile. The arm is internally rotated or positioned across the abdomen. This projection evaluates fractures and soft tissue abnormalities. It complements the AP view. It is a standard ARRT competency.
Position: Shoulder AP External Rotation The AP external rotation shoulder projection demonstrates the greater tubercle. The hand is supinated to externally rotate the humerus. This projection evaluates fractures and degenerative changes. It is essential for shoulder imaging. It is a core ARRT requirement.
