Splenic peliosis mimicking a solid tumor: findings in multimodalities.

abstract：BACKGROUND:Increasing image pitch in computed tomographic (CT) imaging is a method through which scan time can be reduced, which can reduce motion artifacts. In this study, we assess the clinical feasibility of ultrahigh-pitch CT imaging made possible by dual-source CT. METHODS:Image pitch, total scan time, and image ...
