Ukucatshulwa kwe-magnontic resonance kuthethwa ngokufanelekileyo ngenye yezona nkalo zophando kakhulu. Kwi-MRI yentloko kunye nemithambo yegazi yengqondo, kwanokuba utshintsho oluncinane luyabonakala. Inkqubo ayibuhlungu kwaye ayiyigazi.
Izibonakaliso zeMRI yeenqanawa ze-cerebral
Ngethuba lenkqubo yokucatshulwa kwamagnetic magnetic, amasimandla amakhulu amakhulu kunye neentlobo eziphambili ze-frequency zisetyenzisiweyo. Ziyakuvumela ukuba ufumane inkcazo ecacileyo yombutho wezitho kunye nezicubu uze uyizise kwikhompyutha. Iiprogram ezikhethekileyo zenza ukuba kube lula ukucacisa ulwazi olufunyenweyo ekuphuhlisweni kweenqanawa, ubukho bemimiselo okanye ukukhuliswa kwazo, kunye neenguqu ezenzeke kwingqondo.
I-MRI kunye ne-angiography yeempahla ze-cerebral ziboniswa nge:
- ukukrokra kwengqondo yomzimba;
- ukubetha ;
- ukutshatyalaliswa rhoqo;
- ukungabi nantoni kwenhliziyo;
- ukutshatyalaliswa ngokukhawuleza kweememori;
- nzakala;
- rhoqo utywala;
- izifo zentsimbi ye-pituitary;
- ukuphazamiseka kwengqondo;
- ukukhathala ngokukhawuleza;
- ukucaphuka;
- ukuphulwa kolawulo lokuhamba ;
- izifo zendlebe yangaphakathi;
- ukubonakala kobuthathaka kwimilenze.
I-MRI yentloko kunye nemithambo yegazi yengqondo iyakwazi ukubona iinkqubo ezivuthayo ezivela ezindlebeni, kwiimpumlo nakwezono ezinkulu. Emva koko, ingcambu yazo zonke iingxaki ezingentla zihlala zifihliwe engqondweni.
I-MRI yemikhumbi yengqondo yenziwe njani?
Imifanekiso yokuhlaziya i-Magnetic ihlala ingabi ngaphezu kwehafu yeyure. Ngethuba le nkqubo, umongikazi angacela isigulane ukuba sitshintshe ibe yikhati yemvelo engavumelekanga, isuse izinto zegolide kunye nezinto zetsimbi. Ukutya okhethekileyo ngaphambi kokuba i-tomography ingabalandeli. Awunakuguqulwa kwinkqubo kunye nesiqhelo sesiganeko sobomi. Okukuphela kokuphazamiseka - phambi kwe-tomography kuyodinga ukudlula inani leemvavanyo.
Ekubeni kwezinye iimeko ngexesha le-MRI idinga ukufundwa kweenqwelo ze-cerebral ngokuchaseneyo, oogqirha kufuneka bafumane ukuba isiguli sisifo. Ukongezelela, iingcali ziya kufuna ukuthetha ngazo zonke izifo ezidibeneyo, imisebenzi yokudluliselwa, iimpawu zomzimba.
Ngexesha le-tomography, isigulane sifakwa kwisitya esithintekayo. Izixhobo ezikhethekileyo kunye neenzwa zifakwe entloko, ziyakwazi ukufumana nokuthumela amaza omsakazo. Emva koko, umbhede ubeka kwigumbi elikhethekileyo, apho uphando luqhutywa khona.
