Image reconstruction can dramatically reduce the required electrical current and drop chest CT-induced radiation to as low as 3.5 mGy while maintaining acceptable image quality, according to a study published in the May issue of Radiology.

Community radiologists can select from an array of dose management strategies to “counter the wave of alarm over the small and unproven risks of low-dose radiation that is sweeping the country and threatens to undermine the considerable benefits that accrue from careful and judicious use of modern CT technology,” according to a clinical perspective published in this month's American Journal of Roentgenology.
