Magnetic resonance imaging (MRI) panguva yekuvhiya
Nezve bvunzo iyi
Magnetic resonance imaging inopa maonero ehuropi panguva yekuvhiya. Neurosurgeons vanoshandisa iMRI kuvabatsira kubvisa zvirwere zvehuropi nekurapa zvimwe zvirwere senge epilepsy.
Nei ichiitwa
Vanachirurugi vanoshandisa iMRI kubatsira mukuita mabasa anorapira marudzi akasiyana-siyana etumor yehuropi. Kuopera kazhinji ndiyo nhanho yekutanga kurapa tumor inogona kubviswa pasina kukonzera kukuvara kwehuropi. Mamwe matumor ane chimiro chakajeka uye anogona kubviswa nyore nyore. Uyezve, vanachirurugi vanoshandisa iMRI kuisa deep brain stimulators kurapa chirwere chekurova, kufamba-famba kwemuviri, dystonia uye chirwere cheParkinson. iMRI inoshandiswawo kubatsira mukuita mabasa ekurapa mamiriro ezvinhu ehuropi. Anosanganisira kuzvimba kwechibereko cheruoko, kunozivikanwa seaneurysm, uye midziyo yeropa yakapetana, inozivikanwa se arteriovenous malformation. Tekinoroji iyi inogona kushandiswawo mukuita mabasa ekurapa matambudziko ehutano hwepfungwa. Panguva iyi, iMRI inobvumira vanachirurugi kutarisisa basa rehuropi. Inobatsira vanachirurugi kuongorora ropa, clots uye zvimwe zvinetso. Intraoperative MRI inogona kubatsira kudzivirira kukuvara kune tishu dziri pedyo uye kuchengetedza basa rehuropi. Inogonawo kubatsira kugadzirisa matambudziko kare kare. Tekinoroji iyi inogona kuderedza kudiwa kwekuita mabasa akawedzerwa. Kune kuvhiya kenza, iMRI inobatsira vanachirurugi kuve nechokwadi chekuti tumor yose yabviswa.
Zvekutarisira
Vanachirurugi vanoshandisa iMRI kugadzira mifananidzo yehuropi nguva chaiyo. Panguva dzakati dziri pakuvhiya, chiremba anogona kuda kuona mifananidzo yakati yehuropi. MRI inoshandisa magnetic field nema radio waves kugadzira mifananidzo yakajeka yehuropi. Kushandisa tekinoroji yeMRI pakuvhiya, vanachiremba vanogona kuunza muchina we iMRI unotakurika mukamuri yekuvhiya kugadzira mifananidzo. Kana kuti vanogona kuchengeta muchina we iMRI mukamuri iri pedyo kuitira kuti vanachirurugi vagokwanisa kukutakura ipapo kuti uite mifananidzo panguva yekuvhiya. I MRI haigone kushandiswa muvarwere vane map pacemaker akawanda, cochlear implants, uye majoini emetal kana mamwe ma implants.
