Position: AP Patella The AP patella projection demonstrates the patella with reduced magnification. It evaluates fractures and alignment. Proper positioning prevents rotation. This projection complements lateral patella. It is recognized on ARRT exams.
Position: PA Patella Weight Bearing The weight bearing PA patella projection evaluates patellofemoral alignment under load. It is used for chronic instability. Proper positioning ensures diagnostic clarity. This projection complements sunrise views. It is recognized in orthopedic imaging.
Position: AP Shoulder Axial Superior Inferior The superior inferior axial shoulder projection demonstrates the glenohumeral joint. It is used when abduction is limited. Proper angulation isolates the joint. This projection complements axillary views. It is recognized on ARRT exams.
Position: AP Shoulder Axial Inferior Superior The inferior superior axial projection demonstrates the humeral head and glenoid. It evaluates dislocations and labral tears. Proper abduction is essential. This projection complements superior inferior axial. It is recognized in orthopedic imaging.
Position: AP Scapula Y Modified The modified Y projection adjusts rotation for patients with limited mobility. It demonstrates dislocation and scapular fractures. Proper positioning prevents distortion. This projection complements standard Y. It is recognized on ARRT exams.
Position: AP Humerus Weight Bearing The weight bearing humerus projection evaluates alignment under load. It is used for chronic instability. Proper centering includes shoulder and elbow. This projection complements lateral weight bearing humerus. It is recognized in orthopedic imaging.
Position: Lateral Femur Stress The lateral femur stress projection demonstrates the femur in profile under stress. It evaluates instability and stress fractures. Proper positioning prevents rotation. This projection complements AP stress femur. It is recognized in orthopedic practice.
Position: Lateral Humerus Weight Bearing The lateral weight bearing humerus projection demonstrates the humerus in profile under load. It evaluates instability and deformity. Proper positioning prevents rotation. This projection complements AP weight bearing humerus. It is used in orthopedic assessment.
Position: AP Tibia Fibula Stress The tib fib stress projection evaluates ligament integrity and tibial deformity. It is used for chronic instability. Proper centering includes both joints. This projection complements lateral stress tib fib. It is recognized in orthopedic imaging.
Position: AP Elbow Axial The axial elbow projection demonstrates the distal humerus and proximal forearm with angled beams. It evaluates fractures when standard AP is limited. Proper angulation prevents distortion. This projection complements lateral elbow. It is recognized on ARRT exams.
