Position: Barium Enema AP Axial Sigmoid The AP axial sigmoid projection uses a cephalic angle to elongate the rectosigmoid region. It improves visualization of polyps and strictures. Proper centering ensures diagnostic quality. This projection complements oblique views. It is a recognized ARRT competency.
Position: Barium Enema PA Axial Sigmoid The PA axial sigmoid projection uses a caudal angle to open the rectosigmoid region. It reduces superimposition and improves mucosal visualization. Proper positioning prevents distortion. This projection complements AP axial views. It is frequently tested on ARRT exams.
Position: Scapular Y The scapular Y projection demonstrates dislocation and scapular fractures. Proper rotation is essential for diagnostic clarity. This projection complements AP shoulder views. It is heavily emphasized on ARRT exams. It is a core trauma competency.
Position: Barium Enema Decubitus Right The right lateral decubitus projection demonstrates the medial ascending and lateral descending colon. A horizontal beam shows contrast layering. Proper positioning prevents rotation. This projection complements left decubitus views. It is a standard ARRT competency.
Position: Axillary Shoulder The axillary shoulder projection demonstrates the humeral head and glenoid relationship. It evaluates dislocations and labral pathology. Proper abduction is essential. This projection complements AP and Y views. It is a recognized ARRT competency.
Position: Barium Enema Decubitus Left The left lateral decubitus projection demonstrates the lateral ascending and medial descending colon. It is essential for evaluating polyps and masses. Proper centering ensures full colonic visualization. This projection complements right decubitus views. It is frequently tested on ARRT exams.
Position: AP Clavicle The AP clavicle projection demonstrates the entire clavicle. It evaluates fractures and alignment. Proper centering ensures diagnostic quality. This projection complements AP axial clavicle. It is a standard ARRT requirement.
Position: ERCP Lateral The lateral ERCP projection demonstrates the duodenum and biliary tree in profile. It evaluates ductal anatomy and pathology. Proper positioning prevents superimposition. This projection complements AP and oblique views. It is a recognized ARRT competency.
Position: AP Axial Clavicle The AP axial clavicle projection uses a cephalic angle to project the clavicle above the ribs. It evaluates fractures and joint alignment. Proper angulation prevents distortion. This projection complements AP clavicle. It is frequently tested on ARRT exams.
Position: ERCP RAO The RAO ERCP projection demonstrates the pancreatic head and biliary ducts. It improves visualization of ductal narrowing. Proper rotation ensures diagnostic quality. This projection complements AP views. It is frequently used in interventional fluoroscopy.
