Overview
Radiography uses x ray beams and detectors to produce two dimensional projection images. It is fast widely available and the first line modality for many musculoskeletal and thoracic problems.
Technique
Standard views such as AP PA lateral and oblique and correct patient positioning are essential for diagnostic quality. Exposure factors are adjusted for patient size and clinical question.
Clinical Uses
Common indications include fracture detection chest evaluation and line and tube placement. Portable radiography enables bedside imaging for critically ill patients.
Limitations and Safety
Projectional overlap can obscure pathology. Ionizing radiation requires ALARA principles and appropriate shielding.
