MDCT is used to determine how the noise changes as the slice thickness changes. Noise according to thickness of 1.5, 3.0, 5.0 and 10.0 mm was analyzed using the Siemens (Somatom Definition Flash, Germany) equipment and calibration conditions such as tube voltage and tube current using the calibration QC phantom. 1.5, 3.0, 5.0 and 10.0 mm, respectively. The mean HU was 1.5 mm (7.7 HU), 3.0 mm (4.9 HU) and was reduced by 59.5% from 1.5 mm. 5.0 mm (3.9 HU) and 97.6% compared to 1.5 mm, 10.0 mm (3.1 HU) and 148% less than 1.5 mm. It was found that as slice thickness increased, noise decreased, while slice thickness decreased. In conclusion, setting the appropriate slice thickness for each site may be useful for obtaining appropriate noise and image quality.
