Diagnostic quality of CT imaging of the thorax

The paper is aimed at determining diagnostic quality of the images in different chest CT examination protocols. Two groups of patients underwent scanning based on two different protocols using Siemens Somatom 4 Plus scanner in the spiral mode. The study included the total of 64 patients divided in two groups according to their body weight (BW). Group one included 34 patients weighing above 80 kg and they were scanned according to the standard protocol. Group two comprised 30 patients weighting below 80 kg and they were scanned using the same protocol however with reduction of tube current of 13 mA. All the scans were subsequently reconstructed using noise-reduction filter (enhancement of low contrast resolution).
