Abstract

Use of computed tomography (CT) has increased tremendously over the last two decades. Compared to the lowest dose x-ray techniques, CT scans can have 100 to 1,000 time’s higher radiation dose than conventional X-rays. Despite its usefulness, potential risk of radiation induced malignancy does exist which cannot be ignored. One study estimated that as much as 0.4% of all current cancers in the United States are attributable to CT examinations based on CT usage data from 1991–1996. Hence it is imperative to know about CT dose reduction techniques. This review will give readers an insight to strategies for dose reduction and principles behind them.
