Position: AP Airway The AP airway projection evaluates the trachea and proximal bronchi. It is used for foreign body localization and airway narrowing. Proper centering at the manubrium ensures full visualization. This projection complements lateral airway views. It is a standard ARRT requirement.
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 Airway The lateral airway projection demonstrates the trachea and larynx in profile. It is essential for evaluating airway obstruction. Proper positioning prevents rotation and ensures diagnostic quality. This projection complements AP airway views. It is frequently tested on ARRT exams.
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 Sternoclavicular Joints The AP SC joint projection evaluates alignment and dislocation. Proper centering at the manubrium ensures visualization of both joints. This projection is essential for trauma and inflammatory conditions. It complements oblique SC joint views. It is recognized 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: Oblique Sternoclavicular Joints The oblique SC joint projection rotates the patient 10 to 15 degrees to demonstrate one joint without superimposition. It evaluates dislocation and joint space narrowing. Proper rotation is essential for diagnostic clarity. This projection complements AP SC views. It is a standard ARRT competency.
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: AP Ribs Above Diaphragm The AP ribs above diaphragm projection evaluates ribs 1 through 10. Deep inspiration elevates the diaphragm for optimal visualization. This projection is essential for trauma and pain evaluation. Proper centering ensures diagnostic quality. It is frequently tested on ARRT exams.
Position: AP Ribs Below Diaphragm The AP ribs below diaphragm projection evaluates ribs 8 through 12. Expiration lowers the diaphragm for improved visualization. This projection is essential for trauma and abdominal pain evaluation. Proper centering ensures full coverage. It is a standard ARRT requirement.
