Overview
CT acquires multiple x ray projections around the patient to reconstruct cross sectional images. It provides rapid high resolution anatomic detail across the body.
Technique
Modern CT uses helical acquisition multidetector arrays and iterative or AI reconstruction to optimize image quality and dose.
Clinical Uses
Indications include trauma vascular imaging oncologic staging pulmonary embolism evaluation and CT guided interventions.
Limitations and Safety
CT involves ionizing radiation and iodinated contrast risks. Dose optimization and contrast screening are essential.
