Position: Lateral Decubitus Chest Right The right lateral decubitus chest demonstrates left?sided pneumothorax or right?sided effusion. A horizontal beam is essential. Proper positioning prevents rotation. This projection complements left decubitus chest. It is a core ARRT competency.
Position: Lateral Decubitus Chest Left The left lateral decubitus chest demonstrates right?sided pneumothorax or left?sided effusion. It is essential for pleural evaluation. Proper centering ensures diagnostic quality. This projection complements right decubitus chest. It is frequently tested on ARRT exams.
Position: AP Abdomen KUB The AP abdomen KUB projection evaluates kidneys, ureters, and bladder. It is used for obstruction, stones, and bowel gas patterns. Proper centering at the iliac crests ensures full abdominal coverage. This projection is foundational in abdominal imaging. It is a core ARRT competency.
Position: AP Abdomen Upright The upright abdomen projection demonstrates air fluid levels and free air. It is essential for diagnosing perforation and obstruction. Proper centering includes the diaphragm. This projection complements supine KUB. It is frequently tested on ARRT exams.
Position: Left Lateral Decubitus Abdomen The left lateral decubitus abdomen demonstrates free air under the right hemidiaphragm. A horizontal beam is essential. This projection is used when the patient cannot stand. It complements upright abdomen views. It is a standard ARRT requirement.
Position: AP Bladder The AP bladder projection demonstrates the bladder and distal ureters. It evaluates reflux, obstruction, and masses. Proper centering ensures full bladder visualization. This projection complements oblique bladder views. It is frequently tested on ARRT exams.
Position: AP Hand Ball Catchers The ball catchers projection demonstrates MCP joints for rheumatoid arthritis. It uses bilateral oblique positioning. Proper finger separation prevents overlap. This projection evaluates erosions and joint narrowing. It is a recognized ARRT competency.
Position: Oblique Bladder The oblique bladder projection rotates the patient 40 to 60 degrees. It separates the bladder from pelvic bones. This projection evaluates reflux and ureteral injury. Proper rotation ensures diagnostic clarity. It is a recognized ARRT competency.
Position: AP Hand Norgaard The Norgaard projection is another name for ball catchers. It evaluates early rheumatoid arthritis. Proper obliquity is essential. This projection complements standard hand views. It is frequently used in rheumatology imaging.
Position: AP Urogram The AP urogram projection demonstrates kidneys and ureters during IV contrast excretion. It evaluates obstruction and hydronephrosis. Proper timing is essential. This projection complements oblique and bladder views. It is a core ARRT requirement.
