Le ndlela yindlela ephephile futhi ephumelelayo yokuphenya. Inzuzo enkulu ye-MRI yezindwangu ze-cerebral ngaphambi kokuba i-tomography ihlanganiswe ukuthola isithombe esicacile, ngenxa yokuthi kungenzeka yini ukubona lesi sifo esiteji sokuqala. Le ndlela isetshenziselwa kabanzi nge-neurosurgery neurology ukuze kuhlolwe abantu abadala, izingane kanye nabesifazane abakhulelwe.
Iyini i-MRI yobuchopho?
Ukufaneka kwemifanekiso ye-magnetic inikeza izithombe ezimbili-ntathu ngisho nemithathu-ntathu ye-arteries, i-veins nama-tissue azungezile. Le nqubo ikuvumela ukuba uthole ulwazi oludingekile mayelana nokuba khona kwamathologi.
Ngokuchaza ukuthi i-MRI yobuchopho, ukuphefumula kwe-atherosclerosis, i-vasculitis nezinye izinkinga ezikhona kungenzeka. Ngosizo lwezinhlelo ezikhethekile zikhomba izinkomba eziyinhloko, njengehlobo lokugeleza kwegazi kanye ne-spasm ye-arteries.
Izinkomba ze-MRI zobuchopho
Ucwaningo lunconywa iziguli ezinenkinga enjalo:
- phambi kokulimala kwengqondo;
- i-hydrocephalus;
- amathuba okuba khona kwamathumba;
- Izinkinga ekuthuthukiseni ubuchopho bomlingiswa we-innate;
- isithuthwane;
- izifo zokuvuvukala zekhanda lobuchopho;
- i-sclerosis amaningi ;
- izinkinga ngegazi;
- ukuwohloka komqondo
- ama-syndromes ane-convulsive.
Ukulungiselela i-MRI yobuchopho
Inqubo ngokwalo ayidingi izinyathelo ezikhethekile zokulungiselela, ngaphandle kokuba kuhlolwa ukuhlolwa kwe-pelvic. Ngaphambi kwe-tomography kuyadingeka:
- Shintsha ingubo ekhethekile engayizoqukatha izakhi zensimbi.
- Kubalulekile ukususa ubucwebe, iziqeshana zezinwele, amazinyo.
Insimbi inganciphisa ikhwalithi yezithombe, futhi insimu yamagnetic eyenziwe ingakhubaza imishini.
Ngaphambi kwenqubo kubalulekile ukukwazisa udokotela mayelana nokuba khona kwezitho zensimbi, i-valve yenhliziyo noma izimila emazinyo.
I-MRI yobuchopho yenza kanjani?
Ubude benkambiso livela emaminithini amathathu ukuya kwamashumi ayisithupha. Ngenkathi isiguli sisesimweni sokumisa, isithwebuli esitholakala ngaphezu kwekhanda lakhe sidlulisela isithombe kwikhompyutha esesigumbini esilandelayo. Ukuxhumana nodokotela kusekelwa yi-microphone eyakhelwe ngaphakathi.
I-MRI yobuchopho ngokuhlukana ikuvumela ukuba uthole ulwazi oluthe xaxa mayelana nobuchopho. Ngaphambi kwenqubo, i-agent ehlukile yokuphambene ijojowe ngaphakathi, engena egazini, igxila phambi kwezicubu nezicubu ezithintekile.
Ukuqhathaniswa kwe-MRI yobuchopho
I-Tomography iphikisana ngokuqondile namaqembu alandelayo abantu:
- babe nezinto zensimbi ezisekelweni zeso;
- uma kukhona i-pacemaker noma amanye amadivayisi kagesi emzimbeni;
- i-tomography ngokuphambene ayinqatshelwe i-hemopoietic anemia;
- ukuba nengqondo ebuchosheni be-hemostatic.
Ukuqapha kufanele kusetshenziswe lapho kuhlolwa, ezimweni ezinjalo:
- nge- claustrophobia ;
- ukutholakala kwama-prostheses avela ensimbi ezithombeni ezingahlolwa;
- abesifazane abakhulelwe ezinyangeni zokuqala ezintathu zokukhulelwa;
- phambi kwama-tattoos anezici zensimbi;
- ukudakwa ngokweqile;
- lapho usebenzisa izidakamizwa.
Udokotela we-x-ray uzohlaziya isimo sesiguli futhi ngokushesha ngaphambi kokuba inqubo izokhipha isinqumo ngokuziphatha kwayo.
Ingabe kuyingozi ukufeza i-MRI yobuchopho?
Mayelana nemiphumela yemiphumela ku-tomography ayisaziwa. Njengoba lolu cwaningo alusebenzisi imisebe ye-ionizing, lungabuyekezwa ngaphandle kokwesaba. Kungase kube nezibonakaliso ze-claustrophobia ngenxa yesiguli esesikhungweni esivinjelwe. Kubalulekile ukuxwayisa kusengaphambili mayelana nokutholakala nodokotela onjalo we-phobia.
