Methods and Materials 1/ DATA ACQUISITION: MR Philips Achieva 1.5T, Extended MR WorkSpace - anatomical underlay: neuronavigation T1W 3D TFE sag - fMRI: FE EPI BOLD, software IV BOLD •

showing paradigmas by front projection through the window, using mirror, reflexed on a screen placed in examination room



choice of paradigmas - motor task, speech task, vizual activation



using block design paradigm: 4x action changing with 4x relax

-tractography: DTI medium SENSE, software Fibertrak 2/ CLINICAL APPLICATION: • • •

• • •

Preoperative localization of eloquent cortex, correlation with anatomical "landmark" Localization of tracts: cortico spinal tract, fasciculus arcuatus, radiatio optica Determination of the types of tracts alteration: a/ deviation in cases of low grade gliomas, anaplastic astrocytomas, glioblastoma multiforme and metastasis, b/ infiltration in cases of anaplastic astrocytomas, glioblastoma multiforme, c/ destruction in cases of anaplastic astrocytomas, glioblastoma multiforme Speech lateralization - determination of speech dominance Brain plasticity Validation of the data with the direct cortical stimulation using subdural strips - localization of central sulcus

Results Aims of functional imaging: • • •



Increase safety of neurosurgical resection at tumours in eloquent areas Choice of optimal surgical approach Reach maximal possible extent of resection with minimal postoperative morbidity, especially incases of low grade gliomas in young patients Minimize postoperative permanent deficit

Statistics: • • • •

In period of one year - from June 2010 to June 2011, 50 patients were examined - there of 40 were operated, 5 were biopted, 5 were observed Indication: mostly glial tumours low and high grade, within or close to eloquent areas, cavernomas, metastasis Results: all patients without serious postoperative neurological deficit, or without progression existing neurological deficit One serious postoperative complication - bleeding

Conclusion • • •

• •

promptly developing method, time consuming demanding cooperation from patient requiring interdisciplinary consultation between neurosurgeon and neuroradiologist - in preoperative planning: determination the distance between the lesion and eloquent areas or tracts, - in postoperative care: clinical status of pacient, extent of resection, complications and follow-up facilitate the choice of optimal operative approach maximizing extent of resection with minimizing risk of permanent neurological deficit
