DTI & Tractography in Pediatric Tumor Surgery
Application of Diffusion Tensor Imaging and Tractography in Pediatric Tumor Surgery

Detaljert beskrivelse
Brain tumours are the most common form of solid tumours in children which often arise from the cerebellum. Treatment involves a complete resection of the tumour. Although surgical resection may eliminate most of the malignancy, signs of post-neurologic deficit may present as a consequence to the treatment.
One such example is cerebellar mutism syndrome (CMS), a postoperative syndrome typically arising 1 to 2 days after resection of a midline posterior fossa tumor; it consists of diminished speech progressing to mutism, emotional lability, hypotonia, and ataxia. While some of the symptoms recover after a few months, neuropsychological testing shows long term deficits in language (agramatism), executive function and verbal memory.
This study aims to investigate whether the use of Synaptive Medical's BrightMatter™ technology can help neurosurgeons better visualize and plan surgeries by avoiding eloquent fiber tracts in the brain and cerebellum; thus minimizing damage pertaining to neurologic and motor functionality. The use of these products will also be assessed for improved clinical outcomes in pediatric tumor surgery.

---|---|
Ingen inngripen: Control
Control Group (surgical standard of care): Subjects 18 years and younger diagnosed with a pediatric brain tumor, and who are eligible for surgical treatment will be recruited.
All subjects will have clinical MRI scans that include a diffusion tensor imaging (DTI) protocol.
Surgery will be carried out according to usual standard of care, without the use of processing for DTI tractography.
Additional clinical scanning with the same protocol will be carried out post-operatively at 6 months.
Pre-operative and post-operative quality of life assessments, functional testing and clinical outcome tests will be conducted at this post-operative period (6-months).

Annen: Interventional
Interventional Group (involvement of all BrightMatter™ products): Subjects 18 years and younger diagnosed with a pediatric brain tumor and who are eligible for surgical treatment will be recruited.
All subjects will have clinical MRI scans that include a diffusion tensor imaging (DTI) protocol and will be sent to the interventional technology (BrightMatter Bridge) for quality control.
The QC'ed images will then be sent to a pre-operating planning software (BrightMatter Plan) for planning the surgical approach.
Surgery will be carried out with guidance from the exported plan and the intra-operative neuro-navigation software, BrightMatter Guide, with the use of post-processing DTI tractography.
Additional clinical scanning with the same protocol will be carried out post-operatively at 6 months.
Pre-operative and post-operative quality of life assessments, functional testing and clinical outcome tests will be conducted at this post-operative period (6-months).

BrightMatter™ Plan (BMP): BMP er en programvare som gjør det mulig for kirurger å planlegge nevrokirurgien preoperativt. BMP genererer automatisk helhjernetraktografi og svært nøyaktig fusjon av anatomiske MR- og DTI-bilder. BrightMatter™ Bridge (BMB): BMB innebærer å tilby SMIs MR-ekspertise for å sikre en jevn arbeidsflyt i nevroimaging inkludert DTI for å sikre at optimaliserte protokoller brukes til å innhente DTI-bildene. Når bildene er innhentet, blir de evaluert for deres kvalitet i sanntid ved hjelp av en kvalitetskontroll (QC) algoritme. QC tillater kvalitetsvurdering av DTI-bilder på tidspunktet for skanning, noe som gir mulighet for umiddelbar korrigering mens pasienten fortsatt er der og reduserer behovet for ny skanning av pasient. BrightMatter™ Guide (BMG): BMG er et nevro-navigasjonssystem som bruker DTI-informasjonen og banen planlagt av kirurgen i BMP preoperativt, men som bringer den inn i operasjonssalen intraoperativt.
