Characterizing the effects of magnetic field strength on specificity in functional MRI: Application in pre-surgical mapping

Methods Three pre-surgical mapping paradigms (finger tapping, verbal fluency and sentence comprehension) were evaluated in a test-retest paradigm in which ROC curves were generated at field strengths of 1.5T and a 4T. More work assessing test-retest reliability of activation maps computed at each fi...

Summary:Methods Three pre-surgical mapping paradigms (finger tapping, verbal fluency and sentence comprehension) were evaluated in a test-retest paradigm in which ROC curves were generated at field strengths of 1.5T and a 4T. More work assessing test-retest reliability of activation maps computed at each field strength and for different paradigms relevant to pre-surgical mapping applications will be explored in the future.
