Abstract
This chapter provides information on how to perform cardiac CT. According to workflow of practical CT examination, this chapter described considerations regarding patient preparation, CT acquisition, contrast enhancement, reconstruction parameters, and image display techniques. Because physicians have to select optimal methods for successful CT examination every moment from patient preparation to image reformation, this chapter is described in a step-by-step approach. The technique is covered mainly with the latest models such as 64-slice CT, dual-source CT, and wide detector array CT scanners. Progress in CT technology has continuously contributed to improve temporal and spatial resolution. Nevertheless, efforts are still being made to increase image quality. This chapter also reviews how each factor influences spatial and temporal resolution and image noise. Another focus is patient radiation exposure and strategies for dose reduction. A variety of strategies have been currently undertaken to reduce the radiation dose. This chapter finally discusses the technical developments and strategies to reduce radiation dose.
