Abstract
This article reviews dose reduction techniques in pulmonary CT angiography (CTA) for imaging pulmonary embolism (PE). Dose reduction technologies covered include tube current modulation, kilovoltage modulation, scanning length modification, dynamic z-axis collimation, iterative reconstruction, and dual-energy CT. Age- and weight-specific imaging techniques are suggested. Pulmonary CTA plays a vital role in imaging PE. Using dose reduction technologies can provide high-quality diagnostic imaging with a significant reduction in patient dose.
