This study assess if a new one minute multi contrast MRI method has comparable diagnostic performance as conventional MRI in brain imaging. Prospectively consecutively included patients (n=101) underwent a conventional clinical brain MRI in addition to a new 80 seconds multi contrast MRI sequence named EPIMix. The diagnostic performance to categorize a clinical brain MRI scan with EPIMix or conventional MRI as abnormal (symptom-causing lesion) was comparable between EPIMix (AUC 0.97 (95%CI 0.94-1.00) and 0.98 (95% CI 0.96-1.00)) and conventional MRI (AUC 1.00 (95% CI 1.00-1.00)), (n=96-101).
