Overview
Computed tomography uses x ray beams and detectors to create cross sectional images. It provides rapid assessment of anatomy. It is essential in emergency imaging.
Clinical Applications
CT is used for trauma chest abdomen and vascular imaging. It detects fractures bleeding and organ injury. It supports surgical planning and intervention.
Dose Management
Techniques reduce radiation dose while preserving image quality. Iterative reconstruction and protocol optimization are key. Patient shielding and justification are important.
Advanced Techniques
Dual energy and spectral CT enable material characterization. These methods improve lesion detection and tissue differentiation. They expand clinical applications of CT.
