Le ndlela yindlela ekhuselekileyo yokuphumelela yophando. Inzuzo enkulu ye-MRI yeenqwelo ze-cerebral ngaphambi kokuba i-tomography icutshungulwe kukufumana umfanekiso ocacileyo, ngenxa yokuba kunokwenzeka ukuba uyakwazi ukubona isi sifo kwisigaba sokuqala. Le ndlela isetyenziswa ngokubanzi kwi-neurosurgery kunye neurology ukuze kuhlolwe abantu abadala, abantwana kunye nabafazi abakhulelweyo.
Yintoni i-MRI yengqondo?
Ukucabungula nge-magnetic resonance inikeza imifanekiso emibili-ntathu kunye nemifanekiso emithathu yeetriyeri, iimvini kunye nezicubu ezizungezile. Le ndlela ikuvumela ukuba ufumane ulwazi oluyimfuneko malunga nobukho bentlalo.
Ngokucacisa i-MRI yengqondo, i-atherosclerosis, i-vasculitis kunye nezinye izifo ezinokwenzeka. Ngoncedo lweeprogram ezizodwa zichonga izikhokelo eziphambili, ezifana nohlobo lokuhamba kwegazi kunye ne-spasm yeemitha.
Iimpawu zeMRI yengqondo
Uphando luyanconywa kwizigulane ezinengxaki ezinjalo:
- ebusweni bengozi;
- i-hydrocephalus;
- ubunokwenzeka bokuba khona kwezicubu;
- Iimpazamo ekuphuhliseni kwengqondo yomlingiswa we-innate;
- ukuhluthwa;
- izifo ezivuthayo zomlenze wengqondo;
- multiple sclerosis ;
- iingxaki ngegazi;
- ngqondweni
- i-syndromes.
Ukulungiselela i-MRI yengqondo
Inkqubo ngokwayo ayifuni amanyathelo amalungiselelo okhethekileyo, ngaphandle kokuba kuhlolwa i-pelvic. Ngaphambi kokuba i-tomography iyimfuneko:
- Shintsha ube yingubo ekhethekileyo engayi kuba nezinto zetsimbi.
- Kwakhona kubalulekile ukususa iingubo, izicathulo zeenwele, amazinyo.
Umnxeba unokunciphisa umgangatho wemifanekiso, kwaye insimu yamagnetic eyenziwe inokukhubaza izixhobo.
Ngaphambi kokuba inkqubo ibalulekile ukuxelela ugqirha malunga nobukho bentsimbi yesinyithi, i-valve yenhliziyo okanye izilwanyana ezinamazinyo.
I-MRI yengqondo yenziwe njani?
Ubude benkqubo luvela kumashumi amathathu ukuya kumashumi mathandathu. Nangona isigulane sisesikhundleni sokumisa, umseshini ophezu kwentloko yakhe udlulisela umfanekiso kwikhomputha ekhoyo kwigumbi elilandelayo. Ukunxibelelana nogqirha kuxhaswa ngeendlela zemakrofoni ezakhelwe.
I-MRI yengqondo ngokuchaseneyo ikuvumela ukuba ufumane ulwazi olunzulu malunga nengqondo. Ngaphambi kwenkqubo, i-arhente ekhethekileyo eyahlukileyo ijojowe kwangaphakathi, engena kwigazi, igxininise phambi kobuhlungu kunye nezicubu ezichaphazelekayo.
Ukungqinelana kwi-MRI yengqondo
I-Tomography iphikisana ngokucacileyo kula maqela alandelayo:
- ezinezinto zetsimbi kwiziseko zamehlo;
- xa kukho i-pacemaker okanye ezinye izixhobo zecomputer kumzimba;
- i-tomography ngokungafaniyo iyanqatshelwe i-hemopoietic anemia;
- ukuba neengcinga ze-hemostatic zeengqondo.
Ilumkiso kufuneka lisetyenziswe xa kuhlolwa, kwiimeko ezinjalo:
- nge claustrophobia ;
- ubukho beeprothesesi ezivela kwisinyithi kwizitho ezingahlolwayo;
- abafazi abakhulelweyo kwiinyanga zokuqala ezintathu zokukhulelwa;
- ebusweni beempawu eziphathekayo;
- utywala;
- xa usebenzisa iziyobisi.
Udokotela we-x-ray uya kuhlalutya imeko yesigulane kwaye ngokukhawuleza ngaphambi kokuba inkqubo iya kuthatha isigqibo malunga nokuziphatha kwayo.
Ngaba kuyingozi ukwenza iMRI yengqondo?
Ngamaxesha emiphumo emibi kwi-tomography ayikaziwa. Ekubeni uphando alusebenzise i-radiation ionizing, lunokuphindaphindiwe ngaphandle kokwesaba. Kukho iimpawu ze-claustrophobia ngenxa yesigulane esisekuhlaleni. Kubalulekile ukulumkisa kwangaphambili malunga nobugqirha obunjalo.
