Uvavanyo lokuTyikitya oluSebenzisiwe ukuVavanya iStroke, Ukuxoshwa
Ukufunda ukuba kufuneka ufumane ukuhlolwa kwe-imagination magnetic resonance (MRI) kunokusongela. Nangona kunqabile ukuba kufuneka uhlolisise ukuphazamiseka kokulala , kunokusetyenziselwa ukuvavanya isifo (i-cause of potential apnea sleeping ) okanye nokuba nokuhluthwa (okubangela ukuba unobungozi obushushu bokuhlwa ). Nangona amava e-MRI ahlukahluka, unokuhlangabezana nokulindeleke okuqhelekileyo kunye nokufunda okufutshane malunga nale nto kunokufaka ukukhathazeka kwakho.
Funda oko ungalindela kwi-MRI yentloko yokuxilongwa kwengxaki yengqondo.
Yintoni i-Magnetic Resonance Imaging (MRI)?
I-imagery ye-magnontic resonance (MRI) isifundo esingaxhamliyo sokuhlaziya i-radiographic esetyenziselwa ukuxilonga iingxaki zonyango. Ngokufana ne-x-ray, lobu buchule buvumela ukubonakaliswa kwezakhiwo ezingenakufikeleleka ngaphandle kokuhlinzwa. Oku kufezekiswa nokusebenzisa umbane omkhulu, kunokuba i-ray ray i-ray, ngelixa isigulane sihleli etafileni. I-pulse ye-magnet ithinta ama-molecule omzimba womzimba kwaye utshintsho oluthile lunokuveza imifanekiso. I-MRI inceda kakhulu kwiindawo ezithile zomzimba, kubandakanya ingqondo.
I-MRI inokuyalelwa ukuba ugqirha wakho ugxeka ukuba kukho isimo esingaqhelekanga esinokubangela iimpawu zakho. Ngokomzekelo, abanye abantu banokuba ne-apnea yokulala ebumbini ngenxa yesifo. Ngaphandle koko, ukuxhwala okwenzeka ngexesha lokulala kungabangela ukuba i-MRI yobuchopho iphenye isizathu sokuhluthwa.
Ukulungiselela i-MRI
Ngaphambi kwe-MRI, abaninzi abantu baya kuthetha nomgqirha wabo ukuze baxoxe ngesizathu sovavanyo. Njengenxalenye yale nto, ukuhlolwa ngokucophelela kwimbali yakho kuya kwenzeka. Oku kubandakanya uluhlu lokukhangela ukuqinisekisa ukuba iMRI ingenziwa ngokukhuselekileyo. Njengoko iimpawu ze-MRI zenziwa nge-magnet enkulu, kuya kubakho ukufumanisa nayiphi na isinyithi esingaba khona emzimbeni wakho.
Ezinye izinyithi ngaphakathi komzimba wakho zinokuthintela ukuba ungenayo i-MRI, kwaye unokucelwa ukuba:
- Ukuhlinzwa kwangaphambili kunye nezifakelo zetsimbi ezigcinwe (kubandakanywa neengqungquthela zetsimbi, izikhonkwane, iifreyiti, iiplate, i-stents, izicatshulwa, okanye i-staples)
- Izixhobo ezifakekileyo (kuquka i-pacemakers, implants cochlear, iiproports zokunyusa iziyobisi, izivalo zentliziyo, kunye nezishukumisi zentsholongwane)
- AmaTattoos (abo bangaphezu kweminyaka engama-20 ubudala banokuthi banentsimbi kwisinki esenokubangela ukucaphukisa nangona ubungqina beli phepha)
- Sebenza njengomlondolozi
- I-schrapnel yentsimbi egcinwe (iinqununu zeenkunzi)
Ngaphandle kwezi ngcamango, kuya kubakho ukususa ezinye izinto zetsimbi ezifana nobucwebe, ukubhoboza umzimba, izixhobo zokuvalelwa, umsebenzi wezentengiselwano okhutshwayo, njl njl.
Yintoni eyenzekayo ngexesha le-MRI Scan
Kwiimeko ezininzi, i-MRI iya kwenziwa xa ulala phantsi kwinqanaba lakho lokuhlola. Uya kugqitywa ukuze indawo yomzimba efuna ukutshintshwa ifumaneka kwimishini ye-MRI. Unokulala ngentamo kunye nekhanda, intambo, okanye iphepha ukuze ukhululeke ngakumbi. Kukho iibhanti ezimbalwa ezifakwa kwindawo ukukunceda uhlale kwindawo.
Ukuba uya kufumana izinto ezifaniyo kunye nesifundo sakho, umgca we-intravenous (IV) uza kufakwa ngaphambi kokuqala kokuvavanya.
Njengoko uvavanyo luba nomsindo, i-earplugs, i-headphones, okanye ezinye izixhobo zokukhusela iindlebe zingasetyenziswa. Itafile zeemviwo ziya kuhamba kunye nokuphuma kwiphubhu enkulu ngexesha lokufunda. Ngaloo ndlela, unokuba nesibuko sibekwe phezu kwamehlo akho ukuze ukwazi ukubona ngaphandle komatshini.
Xa usuqala ukubeka isikhundla, ubuchwepheshe buya kushiya igumbi. Uya kuba nako ukuthetha nabo ngexesha lokufunda. Baya kuba nako ukubeka iliso kwiindawo ezikufutshane kwaye banokubuyela ngokukhawuleza xa kufuneka imfuneko.
I-MRI ngokwayo iya kuququzelelwa ngokulandelelana kweengcamango. Oku kungadinga ukuba ulale ngamasekhondi okanye imizuzu ngexesha.
I-teknoloji iya kukuhambisa phezu kwe-intercom yeendlela ezimbini njengoko uvavanyo luqhubeka. Kuxhomekeke kwizinto ezicatshulwayo, umvavanyo wonke weMRI ungadlulela malunga nemizuzu engama-45 ukuya kwiyure.
Indlela yokujongana namava e-MRI
Kukho iinkxalabo eziqhelekileyo ezinxulumene nokuba ne-MRI. Uvavanyo luvame ukukhuseleka kwaye lubuhlungu, lunobungozi obunzima bokuzibandakanya, kodwa kukho izinto ezimbalwa ezinokukhokelela ekukhathazeni nasekukhathazeni.
Inkxalabo enkulu kuninzi abantu abaye baziva ngayo i-claustrophobic. Oku kwenzeka xa umntu efakwa kwindawo efihliweyo, njenge-tube ye-MRI, kwaye uziva uxhalaba ngenxa yoko. Nangona ukusetyenziswa kwezibuko kunokunceda, abanye abantu bangadinga imithi yokubanceda bazive bekhululekile. Ukuba unenkxalabo yokuba uya kuba yi-claustrophobic, kufuneka wenze izidingo zakho zaziwe phambi kovavanyo. Ukusetyenziswa kwemishini ye-MRI evulekileyo kunokunciphisa le ntliziyo.
Ukuba unamandla kakhulu, umatshini we-MRI unokuncinci kakhulu ukuba angenele ngaphakathi. Ubungakanani bemilinganiselo buhluka ngokusekelwe kumatshini, kwaye ezinye iindlela zifumaneka ngokuqhelekileyo.
Yintoni eyenzekayo emva kokuba i-MRI Scan
Emva kokuba i-MRI iphelile, kunokufumana ixesha elifutshane lokubuyisela ukuba unikwe imishanguzo ukuze uzive ukhululekile. Ngaphandle koko akukho ukulibaziseka ekubuyiseni kwimisebenzi yakho evamile, ukuvumela ukuba le mvavanyo iqhutywe njengesiphene.
Iziphumo zokuvavanya ziyafumaneka emva kokuba zihlolwe yi-radiologist kwaye ziya kuhanjiswa ngugqirha owayalela iMRI.
