Position: Esophagram Lateral The lateral esophagram projection demonstrates the esophagus in profile. It is essential for evaluating motility disorders, strictures, and aspiration. Proper positioning prevents rotation and ensures the shoulders are posterior to the esophagus. This projection complements AP and oblique views. It is a standard ARRT fluoroscopy competency.
Position: Esophagram AP Supine The AP supine esophagram projection evaluates reflux and esophageal distention. It is used when upright positioning is not possible. Proper centering includes the entire esophagus. This projection complements upright views. It is frequently tested on ARRT exams.
Position: Esophagram RAO Swallow The RAO swallow projection captures dynamic swallowing motion. It demonstrates peristalsis and bolus transit. Proper timing is essential for diagnostic quality. This projection is used in dysphagia evaluation. It is a recognized ARRT competency.
Position: Upper GI LPO The LPO upper GI projection demonstrates the gastric fundus filled with contrast. It evaluates hiatal hernias and gastric rotation. Proper rotation prevents superimposition. This projection complements AP and RAO views. It is frequently tested on ARRT exams.
Position: Upper GI RPO The RPO upper GI projection demonstrates the duodenal bulb and pylorus. It is essential for evaluating ulcers and obstruction. Proper rotation ensures diagnostic visualization. This projection complements AP and lateral views. It is a standard ARRT competency.
Position: Upper GI PA The PA upper GI projection demonstrates the stomach in a compressed position. It improves visualization of mucosal folds. Proper centering ensures full gastric coverage. This projection complements AP and oblique views. It is recognized on ARRT exams.
Position: Small Bowel PA The PA small bowel projection improves bowel separation and reduces magnification. It is used for serial imaging during transit studies. Proper centering follows contrast progression. This projection evaluates Crohn disease and obstruction. It is a core ARRT fluoroscopy competency.
Position: Small Bowel Lateral The lateral small bowel projection demonstrates loops in profile. It evaluates fistulas, strictures, and masses. Proper positioning prevents rotation. This projection complements AP and PA views. It is frequently tested on ARRT exams.
Position: Barium Enema PA The PA barium enema projection demonstrates the colon with reduced gonadal dose. It evaluates polyps, masses, and diverticula. Proper centering ensures full colonic visualization. This projection complements AP and oblique views. It is a standard ARRT requirement.
Position: Barium Enema RPO Sigmoid The RPO sigmoid projection demonstrates the sigmoid colon and rectosigmoid junction. It evaluates strictures and masses. Proper rotation prevents superimposition. This projection complements AP and lateral rectum views. It is frequently tested on ARRT exams.
