Overview

Portable AP chest radiographs are obtained at the bedside for critically ill or immobile patients. The projection results in cardiac magnification and altered lung volumes compared with PA views. Portable imaging enables rapid assessment of lines tubes and acute cardiopulmonary changes.

Technique

Place the detector behind the patient and center to the chest with the x ray tube anterior. Use appropriate exposure and document patient position and limitations. Ensure staff use radiation protection and maintain distance during exposure.

Clinical Indications

Portable chest is indicated for ICU patients postoperative assessment and trauma when transport is unsafe. It evaluates endotracheal tube placement central lines and pleural effusions. Follow up upright imaging is recommended when patient condition allows.

Image Assessment

Account for projectional magnification and rotation when interpreting cardiac size and lung volumes. Evaluate for pneumothorax consolidation and device position. Correlate with clinical status and recommend further imaging if needed.
