Image quality and radiation doses in abdominal CT: A multicenter study.

To benchmark image quality and corresponding radiation doses for acute abdominal CT examination across different laboratories and CT manufacturers. An anthropomorphic phantom was scanned once with local abdominal CT protocols at 40 CT scanners, from four vendors, in thirty-three sites. Quantitative image quality was evaluated by CNR and SNR in the liver and kidney parenchyma.
