Image compression helps perfecting the utilization of limited storage and network resources for medical imaging. In many recent studies, H.264 video compression was deemed to be a promising option. This study was the first of its kind in studying the effect of H.264 compression on the image quality of the CT abdominal images acquired in 12-bit density resolution. In this study, 67 sets of abdominal CT scans were used for quantitative image quality analysis, and indicated that the H.264 algorithm worked on a content dependent manner, especially at high compression levels.
