Position: PA Sinuses Caldwell The Caldwell sinus projection demonstrates frontal and ethmoid sinuses. A horizontal beam shows air fluid levels. Proper angulation prevents petrous ridge overlap. This projection complements Waters. It is a standard ARRT requirement.
Position: AP Soft Tissue Neck The AP soft tissue neck projection evaluates the airway, larynx, and upper trachea. It is used for suspected foreign bodies, swelling, or airway narrowing. Proper centering at C4 ensures visualization of the laryngeal structures. A slow breathing technique may improve soft tissue contrast. This projection is a core ARRT competency … Read more
Position: Waters Sinuses The Waters sinus projection demonstrates maxillary sinuses. Proper chin elevation projects petrous ridges below the sinuses. This projection evaluates sinusitis and fractures. It complements Caldwell and lateral views. It is frequently tested on ARRT exams.
Position: Lateral Soft Tissue Neck The lateral soft tissue neck projection demonstrates the airway in profile. It is essential for diagnosing epiglottitis, croup, and foreign bodies. A horizontal beam is used to show air fluid levels. Proper positioning prevents rotation and ensures diagnostic clarity. It is frequently tested on ARRT exams.
Position: Open Mouth Waters Sinuses The open mouth Waters projection demonstrates the sphenoid sinus through the open mouth. It evaluates sinusitis and sphenoid pathology. Proper positioning is essential. This projection complements standard Waters. It is recognized on ARRT exams.
Position: Lateral Sinuses The lateral sinus projection demonstrates all sinus groups in profile. It evaluates air fluid levels. Proper positioning prevents rotation. This projection complements AP and Waters views. It is a core ARRT competency.
Position: AP Thorax Soft Tissue The AP thorax soft tissue projection evaluates the upper airway and mediastinum. It is used for masses and tracheal deviation. Proper centering ensures diagnostic quality. This projection complements lateral soft tissue views. It is frequently tested on ARRT exams.
Position: Lateral Thorax Soft Tissue The lateral thorax soft tissue projection demonstrates the airway and mediastinum in profile. It evaluates masses and airway narrowing. Proper positioning prevents rotation. This projection complements AP soft tissue. It is a standard ARRT requirement.
Position: AP Mobile Chest The AP mobile chest projection evaluates lungs, heart, and lines/tubes. It is used in ICU and trauma settings. Proper centering prevents rotation. This projection complements lateral chest when possible. It is a core ARRT mobile competency.
Position: AP Mobile Abdomen The AP mobile abdomen projection evaluates bowel gas patterns and acute pathology. Proper centering ensures full abdominal coverage. A horizontal beam may show air fluid levels. This projection is essential for emergency imaging. It is frequently tested on ARRT exams.
