Position: Chest AP Lordotic
The AP lordotic projection visualizes the lung apices free of clavicular superimposition. The patient leans backward or the tube is angled cephalad to project the clavicles superiorly. This view is used to evaluate apical lesions such as tuberculosis or Pancoast tumors. Proper positioning prevents distortion of the ribs and sternum. It is a recognized special projection on ARRT exams.
