Our aim was to evaluate changes in texture features based on variations in CT parameters on a phantom. Scans were performed with varying milliampere, kilovolt, section thickness, pitch, and acquisition mode. Forty-two texture features were extracted by using an in-house-developed Matlab program. Two-tailed tests and false-detection analyses were performed with significant differences in texture features based on detector array configurations ( values = 0.001-0.006), section thickness ( values = 0.0002-0.001), and acquisition mode ( values = 0.003-0.006). Variations in milliampere and kilovolt had no significant effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
