Dual energy CT to reveal pseudo leakage of frozen elephant trunk

Abstract

In this case report dual energy CT information was used to reveal a pseudo leakage of a frozen elephant trunk stent. Different materials, which could not be distinguished based on attenuation number, were distinguished with the use of material decomposition algorithms using DECT acquisitions. By using material decomposition imaging, the DECT system proved that in this case the extraluminal densities were not caused by leakage but by a Teflon Felt supported suture.
