Objectives: The aim of this study was to identify imaging protocols in patients with infective endocarditis (IE) through a nationwide survey. Methods: An electronic evolutionary survey was sent to interventional Neuroradiologists among neuroradiological centers under the aegis of the Société Française de Neuroradiologie. Among 33 contacted centers, 25 completed the survey (21 universitary hospitals and 4 peripheric hospitals). Results: Most of the centers (88%) use systematic imaging screening in IE patients. Magnetic Resonance Imaging (MRI) is the first imaging method used in 66% of cases while computed tomography (CT) is used in 44%. When no Infective Intracranial Aneurysm (IIA) is detectable in CT-scan screening, 6 (54,54%) use no further investigation, while 9 (81,81%) continue with MRI exploration in case of hemorrhage, ischemia or enhancement. Sulcal hemorrhage in MRI is an indication of complementary Digital subtraction angiogram (DSA) in 25 centers (100%). Regarding IIA characterization, 12 centers (48%) use systematic DSA, whereas for 10 centers (40%), DSA is conditioned by hemorrhage or patient status. Conclusion: We highlighted large variations in Neuroimaging exploration and follow-up of IE patients in real-world practices. Expert guidelines able to standardize practices are warranted to improve the management of this serious and often misdiagnosed pathology. 21 NANT 182M
