Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
Dual-Energy CT (DECT) aortogram study in a patient with recent endovascular aneurysm repair (EVAR) for an abdominal aortic aneurysm (AAA).
Reconstituted conventional CT angiogram images (Figure A and B) shows hyperdense material in the right posterolateral aspect of the excluded aneurysm sac (arrow) which is in close proximity to the origin of a left lumbar artery (arrow head)
Post-processing DECT virtual contrast/iodine overlay images clearly depict orange colored area in the excluded aneurysm sac confirming with certainty the presence of a type II endoleak.
Case Discussion
DECT was performed on the Siemens SOMATOM Definition Flash scanner. Credit to Jit Pratap, chief radiographer, for assistance in post-processing of the data.
