Position: Pelvis AP The AP pelvis projection demonstrates the entire pelvis and proximal femora. The legs are internally rotated to profile the femoral necks. This projection evaluates fractures, dislocations, and degenerative changes. It is foundational for trauma imaging. It is a core ARRT requirement.
Position: Hip AP The AP hip projection demonstrates the proximal femur and acetabulum. Internal rotation reduces femoral anteversion. This projection evaluates fractures and joint pathology. Proper centering ensures accurate visualization. It is a standard ARRT competency.
Position: Hip Frog Lateral The frog lateral hip projection demonstrates the femoral head and neck in profile. The leg is flexed and abducted. This projection evaluates fractures and pediatric pathology. It complements the AP view. It is frequently tested on ARRT exams.
Position: Hip Cross Table Lateral The cross table lateral hip projection is used in trauma when the patient cannot move. A horizontal beam demonstrates the femoral neck without rotation. This projection is essential for fracture evaluation. Proper positioning requires precise alignment. It is a core ARRT trauma competency.
Position: Knee AP The AP knee projection demonstrates the distal femur, proximal tibia, and joint space. Proper centering ensures accurate visualization. This projection evaluates fractures, arthritis, and alignment. It is a standard ARRT requirement. It complements lateral and oblique views.
Position: Knee Lateral The lateral knee projection demonstrates the patella, joint space, and soft tissues. The knee is flexed 20 to 30 degrees. This projection evaluates effusion and fractures. Proper positioning prevents rotation. It is a core ARRT competency.
Position: Thoracic Spine AP The AP thoracic spine projection demonstrates vertebral bodies and intervertebral spaces. Proper exposure penetrates the thoracic region. This projection evaluates fractures, scoliosis, and degenerative changes. It is a core ARRT competency. It complements the lateral view.
Position: Knee Oblique Medial The medial oblique knee projection demonstrates the tibial plateau and fibular head. This view evaluates fractures and joint pathology. Proper rotation is essential for accurate visualization. It complements AP and lateral views. It is frequently tested on ARRT exams.
Position: Thoracic Spine Lateral The lateral thoracic spine projection demonstrates vertebral alignment and disk spaces. A breathing technique may blur ribs. This projection is essential for trauma and pathology evaluation. Proper positioning prevents rotation. It is a standard ARRT requirement.
Position: Knee Oblique Lateral The lateral oblique knee projection demonstrates the lateral femoral condyle and tibial plateau. This projection evaluates fractures and degenerative changes. Proper rotation prevents superimposition. It is a standard ARRT competency. It enhances joint assessment.
