I-MRIs isebenzisa izixhobo zamagnetic kunye namaza omsakazo, kungekhona imitha
Kulabo abanama-multiple sclerosis (MS), ukuhlolwa kwe-MRI yenzeke rhoqo. Ininzi yenu mhlawumbi ninayo ngonyaka, kunye neyongezelelweyo iyalelwe ukuba i-neurologist ikhumbuza ukuphindaphinda , iimpawu zakho zibuhlungu kakhulu, okanye ukuba uthatha inxaxheba kwilingo lekliniki.
Ngokuqinisekileyo, ubuncinane ubuncinane be- MRI xa ubukho kwinkqubo yokufumanisa i-MS .
Ngaloo nto, kuyinto engokwemvelo ukubuza ukuba ngaba ungekho yini kwi-radiation ngexesha le-MRI scan. Impendulo emfutshane "ayikho." Awunakuboniswa kuyo nayiphi na imirhumo ngexesha le-MRI (imagination magnontic resonance imaging).
Makhe sibambe ubunzulu, nangona kunjalo, ukuba i-MRIs isebenze njani, ingqalelo ukuba akukho mijelo esetyenziswayo.
Ubume be-MRI
"I-MRI" ibhekisela " kumfanekiso wokumangalisa magnetic ," kwaye isebenzisa imihlaba yamagnetic kunye namaza omsakazo (kungekhona imitha) ukuvelisa imifanekiso. I-MRI iyisisombululo esibaluleke kakhulu esisetyenziswe kokubili ukuxilongwa kwe-MS kunye nokubeka esweni isifundo somntu wesifo.
Ngethuba le-MRI, amaza emsakazo anamandla kakhulu (amawaka angama-10,000 kuya kuma-30,000 angamaxesha anamandla kunokwakheka kweempawu zomhlaba) athunyelwa ngomzimba. Oku okwenza okwethutyana i-nuclei ye-athile (ikakhulukazi i-hydrogen) eyenza iiseli zomzimba. Xa befuduka, baphuma amaza abo omsakazo, athathwe ngumseshini. Iprogram yekhomputha koko iguqulela le datha kwimifanekiso, leyo i-radiologist ingayichaza.
Kukho iintlobo ezimbini ezahlukeneyo ze-MRIs ezisetyenziswe kwi-sclerosis ezininzi, izicatshulwa ezi -T1 ezilinganiselweyo kunye nezicatshulwa ezi-T-2. Basebenza ngokungafaniyo ukuncedisa i-neurologist ngokugqithiseleyo ukuqonda i-MS yomntu.
Iimpawu zeT1-Weighted Scans
Iimpawu ze-MRI ezixhaswe nge-T1 zibonelela ngolwazi malunga nomsebenzi wesifo sangoku, njengokuba ngaba okanye bengenawo ukuphindaphinda.
Ngokomzekelo, ukuba umntu onokubuyiselwa kwakhona kwe-MS unempawu ezintsha ze-neurological, ugqirha wakhe unokuyalela i-TRI-weighted MRI scan ephucukisiwe kunye ne-gadolinium (umzekelo). Ukuba ukuvuvukala kwenzeke kwingqondo, i-gadolinium iya kukwazi ukungena nokukhanyisa ezo ndawo zengozi ye-myelin (ezibizwa ngokuba zizilonda ze-MS).
Iimpawu ze-MRI ezilinganiselwa kwi-T1 zibonelela ngolwazi malunga nemimandla yengozi engapheliyo ye-myelin kunye nomonakalo we-nerve fiber-ezi ziboniswa "njengezimbobo ezimnyama."
Izicwangciso zeT2-Weighted Scans
Iimpawu ze-MRI ezilinganiswe nge-T2 zibonelela ngolwazi malunga nenani lezilonda (nokuba litsha okanye elidala). Ezi zilonda zibonakalisa nje ngokuba "amabala aqaqambileyo," kwaye zinika oogqirha ingqiqo yomthwalo wonke womntu we-MS. Ngamanye amaxesha izilonda ziyacaca kwaye ngamanye amaxesha ziyaqhubeka kwaye zikhule zibe ngamabala amnyama (isibonakaliso somonakalo wesigxina osisigxina).
Ii-MRIs ziyimfuneko kwi-MS Care
Nangona kungenangalisa ukuba ucinge ngamasimangethi kunye namaza omsakazo athunyelwa emzimbeni wakho, akukho mngcipheko kuwo onke amathambo omzimba wakho ngexesha le-MRI scan.
Oko kuthethwa, ukuba unayo izixhobo ezifakwe kwisinyithi, zingenako ukusebenza okanye zingabangela ingxaki. Ngoko ke, kubalulekile ukuba uxelele ochwephesha wakho phambi kwayo nayiphi na ifowuni, isikratshi, iplati okanye nayiphi na into onayo emzimbeni wakho ukuba ungazalwanga.
Ingozi kuphela eyingozi evela kwi-MRI yingozi enkulu yokusingathwa kwe-gelolinium, ukuchasana okusetyenziswa kubantu abane-MS esebenzayo. I- gadolinium inokukhanyisa indawo yokuvuvukala okanye ukulahleka kwe-myelin kwingqondo kunye / okanye intambo yomthambo.
Kwakhona, abantu abanezintso ezinobungozi basemngciphekweni wesimo esibi kakhulu, esibizwa ngokuthi i-nephrogenic systemic fibrosis, ebangelwa yi-gadolinium.
Ukubeka iRidiyo yezoNyango kwiPhepha
Nangona unokuba ukhathazeke ngemitha evela kwiimvavanyo zonyango ezifana ne-CT, iyakucima ingqondo yakho ukucinga ngale ngcamango-sizungezwe ngamayeza. Uluntu lwethu lwekhompyutha, olupheleleyo lweekhomputer, iifowuni, kunye neethelevishini, zisifaka kwiimitha zemihla ngemihla.
Khawucinge kwakhona ukuba xa usuka kwi-plane ogwini oluya kunxweme ufumanisa umlinganiselo ofanayo we-radiation njengoko unayo isifuba sakho.
ILizwi
Ekugqibeleni, ukuba unenkxalabo malunga nokunyuka kwakho kwimizila, ukuchasana, okanye nayiphi na into ngexesha lovavanyo oluhlobene noxanduva lwempilo, xela ugqirha wakho. Nonke unokulinganisela izibonelelo kunye nobungozi. Ngokuqhelekileyo lowo owayengumntu mkhulu kunokokugqibela xa exoxa nge- MRI , kodwa esi sigqibo sokuba bobabini unokuhlangana.
