Abstract Objective Quantitative MRI (qMRI) methods provide versatile neuroradiological applications and are a hot topic in research. The degree of their clinical implementation is however barely known. This survey was created to illuminate which how qMRI techniques currently applied across Europe. Methods In total, 4753 neuroradiologists from 27 countries received an online questionnaire. Demographic professional data, experience with the brain head neck, usage, reasons for/against application, knowledge QIBA EIBALL initiatives were assessed. Results Two hundred seventy-two responders 23 used following clinically (mean values %): DWI (82.0%, n = 223), DSC (67.3%, 183), MRS (64.3%, 175), DCE (43.4%, 118), BOLD-fMRI (42.6%, 116), ASL (37.5%, 102), fat quantification (25.0%, 68), T2 mapping (16.9%, 46), T1 (15.1%, 41), PET-MRI (11.8%, 32), IVIM (5.5%, 15), APT-CEST (4.8%, 13), DKI (3.3%, 9). most frequent usage indications for any technique tissue differentiation (82.4%, 224) oncological monitoring (72.8%, 198). Usage differed between countries, e.g. ASL: Germany ( 13/63; 20.6%) vs. France 31/40; 77.5%). Neuroradiologists endorsed use because improved diagnostic accuracy (89.3%, 243), but 50.0% 136) need better technology, 34.9% 95) wish more communication, 31.3% help result interpretation/generation 85). not well known (12.5%, 34, 11.0%, 30). Conclusions highly variable. Beyond aspect readiness use, availability support wider dissemination guidelines could catalyse broader implementation. Key Points • endorse as they subjectively improve accuracy. Clinical variable techniques, indications. advanced imaging be promoted through increase technical training both doctors technicians.
