Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: aneurysm treated with a flow diverter; 18 years or older

Exclusion criteria

Exclusion criteria: known contra-indications to ceMRA, sCTA or DSA, renal insufficiency

Design outcomes

Primary

MeasureTime frame
The main study endpoint is the number of false negative findings for aneurysm occlusion as measured by sCTA and ceMRA according to modified Raymond-Roy classification.—

Secondary

MeasureTime frame
The secondary study endpoints include positive and negative predictive value, sensitivity, specificity for complete aneurysm occlusion; degree of aneurysm occlusion, parent artery patency, device deployment, wall apposition and neck coverage as measured by sCTA and ceMRA; complications related to diagnostic methods and interreader agreement for all the imaging techniques.—
