Position: AP Femur The AP femur projection demonstrates the entire femur. Proper centering includes hip and knee joints. This projection evaluates fractures and alignment. It complements lateral femur views. It is a standard ARRT requirement.

Position: Cross Table Hip The cross table hip projection demonstrates the femoral neck without rotation. A horizontal beam is essential for trauma evaluation. Proper alignment prevents distortion. This projection is a core ARRT trauma competency. It complements AP hip views.

Position: Lateral Hip Frog The frog lateral hip projection demonstrates the femoral head and neck in profile. It evaluates fractures and pediatric pathology. Proper abduction is essential. This projection complements AP hip views. It is frequently tested on ARRT exams.

Position: AP Hip The AP hip projection demonstrates the proximal femur and acetabulum. Internal rotation reduces anteversion. This projection evaluates fractures and joint pathology. Proper centering ensures diagnostic quality. It is a core ARRT requirement.

Position: AP Axial SI Joints The AP axial SI joint projection uses a cephalic angle to open the joint spaces. It evaluates degenerative changes and inflammation. Proper centering ensures diagnostic quality. This projection complements oblique SI views. It is recognized on ARRT exams.

Position: Lateral L5 S1 Spot The L5 S1 spot projection demonstrates the lumbosacral junction. It evaluates spondylolisthesis and disk space narrowing. Proper beam angulation is essential. This projection complements standard lateral lumbar views. It is frequently tested on ARRT exams.

Position: Oblique Lumbar Spine Oblique lumbar projections demonstrate the pars interarticularis. The “Scottie dog” appearance helps identify defects. Proper rotation is essential for accurate visualization. This projection evaluates spondylolysis. It is a core ARRT competency.

Position: Lateral Lumbar Spine The lateral lumbar spine projection demonstrates vertebral alignment and intervertebral foramina. It evaluates spondylolisthesis and disk narrowing. Proper positioning prevents rotation. This projection complements AP views. It is frequently tested on ARRT exams.

Position: AP Lumbar Spine The AP lumbar spine projection demonstrates vertebral bodies and disk spaces. Proper centering ensures visualization of L1 through L5. This projection evaluates fractures, degenerative changes, and alignment. It complements oblique and lateral views. It is a standard ARRT requirement.

Position: Lateral Thoracic Spine The lateral thoracic spine projection demonstrates vertebral alignment and disk spaces. A breathing technique may blur ribs for improved visualization. This projection evaluates trauma and pathology. Proper positioning prevents rotation. It is frequently tested on ARRT exams.
