The functional imaging of brain cortex by BOLD technique was adopted.Results In all subjects, BOLD fMRI showed regular signal intensity time curve in local active areas. Distinct functional images were obtained in all cases. Displacement or shrinkage of functional activation area due to adjacent space occupying lesions could be found.Conclusion BOLD fMRI is an effective method in localizing acoustic language cortex and is valuable for evaluating intracranial mass lesion before surgery.Read More
