Computed tomography, more commonly known as CT or CT scan, is an important diagnostic medical imaging test. This CT CE course titled Image Evaluation and Archiving will cover best-practice techniques for minimizing artifacts during CT scanning. The basic concepts of image acquisition will be explored, including tips for evaluating image quality and methods to archive images. The presentation will discuss the factors that influence image evaluation in CT, including inherent scanner features as well as additional efforts from the technologist. In addition, we will discuss the use of teleradiology with transmitting and receiving imaged from remote imaging centers.
