Uchishandisa hunyanzvi hwekugadzira mepu yehuropi hunodaidzwa kuti diffusion tensor imaging (DTI), ma neurosurgeon anogona kugadzirisa mavhiyirwo ehuropi zvakanyanya zvekuti anogona kubvisa mabundu pasina kukuvadza zvikamu zvehuropi zvine chekuita nemabasa akakosha sekutaura, kuona, uye kufamba.

Vatsvagiri kubva kuYunivhesiti yePennsylvania's Perelman Chikoro cheMishonga vakaongorora ichangoburwa tsvakiridzo yeurourosurgery pamaitiro emunhu ekugadzira mepu yehuropi, uye vakawana kuti kuoneswa kwekubatana kwechinhu chena muuropi panguva yekuvhiyiwa kwebundu rehuropi kunogona kuvandudza huroyi uku uchidzikamisa kukuvara kwechibvumirano.

"Tinogona kuona huropi kubva mukati kunze ikozvino, nemifananidzo ye3D inotsanangura kubatana mukati meuropi, kugadzira mepu chaiyo yekushanda," akadaro munyori mukuru Dr. Steven Brem, co-director wePenn Brain Tumor Center, mukubudiswa kwenhau..

Akawedzera kuti "ikozvino tine ruzivo rwakadai nezvebundu rehuropi hwemunhu wega - kusanganisa diffusion tensor imaging uye kufungidzira kwepamberi neiyo yese yemunhu diagnostics yekuongorora inowanikwa kune vese varwere veuropi tumor," kuti kuvhiyiwa kwega kwega kwebundu rehuropi kunogona kurongeka kune yakasarudzika neurophysiology. murwere.

Ongororo iyi, yakabudiswa mupepanhau Neurosurgical Focus, yakawana kuti muboka revarwere vane mamota ehuropi epamusoro-soro, nzira yekugadzira mepu yehuropi yakawedzera kupona mushure mekuvhiyiwa kusvika mwedzi ingangoita 21.2. Nhengo dzeboka rekutonga uko DTI isina kushandiswa, kune rumwe rutivi, yakararama kusvika paavhareji yemwedzi ye14 mushure mekuvhiyiwa.

Diffusion tensor imaging imhando yemagnetic resonance imaging (MRI) inoteedzera mafambiro uye mafambiro emamorekuru emvura achitevedza maturakiti machena muuropi. Iyo inozobuda ye3D modhi yewhite matter fibers inonzi "diffusion tensor," uye inopa mepu ine mavara-code inoratidza chaizvo kuti tsinga dzehuropi dzakaitwa sei.

"Mifananidzo yeDTI inogona kuvharwa nemifananidzo yeMRI yemaitiro uye inoshanda, ichipa mepu yakasanganiswa inoratidzira topography yakafukidzwa nemepu yemugwagwa," akadaro Dr. Kalil Abdullah, munyori anotungamirira wepepa.

"Iyi shanduro inotipa kujekesa kwakawedzera kuti tifungidzire akakosha maturakiti echinhu chena muuropi uye kugadzirisa nzira dzedu dzekuvhiya kuti dzienderane nenyaya yemunhu wega. Pane kungotarisa pakubvisa bundu chete, tinogona kudzivirira kukuvadzwa kwenyama ine hutano uye kuchengetedza nzira dzakakosha dzinokonzeresa kutaura., kuona uye kushanda kwemotokari."

Vanyori vezvidzidzo vanonyora kuti diffusion tensor imaging inobatsira mukugadzira mepu yehuropi yekuvhiyiwa bundu kunoita kuti ive nzira yakakosha yekubudirira kwemapurojekiti makuru ekugadzira mepu, seHuman Connectome Project inotsigirwa neNational Institutes of Health, uye ingangoita hutongi hwaObama nguva pfupi yadarika. yakazivisa Brain Activity Mepu (BAM) chirongwa zvakare.

Maererano nekusunungurwa, vatsvakurudzi vari kushandura zvavakawana kune yakajairika maitiro ekuvhiya. Vanotarisira kushandisa mepu yehuropi yemunhu ane diffusion tensor imaging kuenderera mberi nekutsanangura kuti kushomeka kwemutauro kunotsanangurwa sei neural dysfunction isati yavhiyiwa bundu, uye kuti vanochinja sei kana kugadzirisa mushure mekurapwa.
