Brief Summary:
A single site cross-sectional comparison of paired diagnostic imaging modalities
This study will show the sensitivity and specificity of CEUS in detecting the various types of endoleaks in comparison to tCTA following EVAR It will collect data to allow comparison of diagnostic accuracy across modalities including CDU CEUS and tCTA It will collect time taken to perform the various types of scan to allow healthcare costs to be calculated for each imaging modality

Detailed Description:
This study will show the sensitivity and specificity of CEUS in detecting the various types of endoleaks in comparison to tCTA following EVAR It will collect data to allow comparison of diagnostic accuracy across modalities including CDU CEUS and tCTA It will collect time taken to perform the various types of scan to allow healthcare costs to be calculated for each imaging modality
Collected data will be analysed regarding two novel hypothesised methods of using CEUS information
The first is recording temporal delay between contrast in graft and contrast in endoleak to define endoleak type Potentially this could be used as a faster method of defining endoleak type in a surveillance programme
The second is to identifyrefute correlation between CEUS contrast to appear in endoleak vs tCTA contrast to appear in endoleak If an association can be established CEUS timings could potentially then be used to time standard CTA phases to improve CTAs diagnostic accuracy
