Abstract

The purpose of this study is to examine an antialiasing method in the breath-hold coronal imaging of the thorax or abdomen. This paper reports a new method of preventing the aliasing artifacts of arms using "Hertz II" as a electromagnetic-wave shield fabric (ESF),which is a very thin and flexible special synthetic fabric. In this study, the ESF method was compared with various conventional preventive measures. Temperature changed around the ESF was also measured by using a fiber optic temperature measurement system during the MR scanning procedure. In addition, the ESF method was tried to use for scanning with some volunteers and some patients in clinical examinations. The results of this study showed that the ESF method could efficiently prevent the aliasing of arms in the MR images. Furthermore, safety of the subjects was hardly affected by the ESF method during MR imaging. Therefore, we concluded that the ESF method was an effectual antialiasing method in the imaging of the thorax or abdomen by using the fast breath-hold scanning.
