Title: SYSTEM FOR PROVIDING IMAGES FOR ENDOLEAK DETECTION
Abstract:
The invention relates to a system for providing images for detecting an endoleak after a stent graft has been placed within the aorta of a person at a stent graft location. First and second contrast agents are injected at first and second times (T1, T2) and first, second and third computed tomography images of the stent graft location showing a) the first contrast agent, b) the second contrast agent and c) the stent graft and tissue, respectively, are reconstructed based on spectral projection data acquired at a third time (T3). By using these computed tomography images for detecting an endoleak, the endoleak detection can be significantly improved, wherein this improved endoleak detection can be provided with a relative low radiation dose, because the images can be reconstructed by using only the computed tomography scan at the third time.
