Ukuhlolwa kwe-imaginous magontic resonance, noma i- MRI , kuyinto yokuhlola i-imaging esetshenziselwa ukuxilonga i- MS . Ngaphandle kokuxilongwa, i-MRIs nayo isetshenziselwa ukuhlola ukuqhubekela phambili kwesifo, njengokunikeza ukukhombisa ukuthi umuntu uphendula kanjani kahle ukwelashwa kwabo kwe-MS. Umuntu angathola i-MRI ebuchosheni bayo kanye / noma intambo yomgogodla, kuye ngezibonakaliso zakhe.
Lezi zinhlobo ezimbili zama-MRIs ezisetshenziselwa ukuqonda izibalo eziningi zomuntu yizilinganiso ezilinganiselwe ze-T1 nezi-T-2.
Iyini i-MRI ene-T1-Weighted?
Ukuskena kwe-imagery resonance imaging (TRI) ene-T1 ibonisa izilonda ze-hypointense, ezibizwa nangokuthi "izimbobo ezimnyama," ngoba zibonakala zibe mnyama ezithombeni. Lezi "izimbobo ezimnyama" zingase zimelele izindawo zokulimala noma ukulahlekelwa okungapheli kwe- myelin kanye ne-axonal, ikakhulukazi uma kunomnyama kakhulu. Ngamanye amazwi, indawo ebumnyama, ukulimala okuningi kwenziwe.
Uma i-myelin nama-axon ewonakele noma ebhujisiwe, amangqamuzana omzimba angakwazi ukuxhumana kahle noma noma kunjalo-yilokho okubangela izimpawu zomuntu ezihlukile ze-MS.
Kubalulekile ukuqaphela ukuthi ngaphezu kokulahlekelwa kwe-axonal okuhlala unomphela, "umgodi omnyama" noma i-lesion esinezintambo ezilinganiselwa ku-T1 zingase zimelele izindawo ze-edema, noma ukuvuvukala, okwesikhashana futhi kwanyamalala ezinkathini ezilandelayo. Yingakho i-neurologist izovame ukuqhathanisa i-MRI yakho yamanje ne-MRIs endala-ukubona ukuthi izilonda zixazululwe.
Iyini i-MRI ene-T2-Weighted?
Iskrini se-TRI esinezintambo ezine-magnesium resonance (MRI) sibonisa inani eliphelele lezilonda ze-MS. Lesi sibonakaliso esihle somthwalo womuntu we-MS ngaphezu konyaka odlule. I-MS izilonda kwi-T2-isisindo se-MRI ibonakala njengezilonda ze-hyperintense, noma "izindawo eziqhakazile" futhi ngokuvamile zibhekwa njengama-plaque.
Uma ama-plaque aqhubeka evuvuka kabusha, angagcina esephenduka "izimbobo ezimnyama." Lokhu kuthiwa, ngezinye izikhathi ama-plaque angaphilisa, azilungiselele futhi aphele.
Kusho ukuthini Ukuthola Ukungafani?
Ngenkathi umuntu ephethe i-MRI, uchwepheshe we-MRI angabanika umehluko nge-vein ebizwa ngokuthi i-gadolinium. Uma i- gadolinium ingena kwi-MS lesion kwi-MRI , izokhanya . Isilonda esibheka phezulu sibonisa indawo yokuvuvukala okuhlobene ne-MS, okusho ukuthi ukudilizwa komzimba kuye kwenzeka ezinyangeni ezimbili noma ezintathu zokugcina.
Izwi elivela
Kubalulekile ukuqonda ukuthi i-MRI iyithuluzi elisetshenziswa izazi zezinzwa ukuze lihlolwe i-MS futhi ubone ukuthi umuntu uphendula kanjani kahle ukwelashwa. Kodwa izilonda kwi-MRI azihambisani ngaso sonke isikhathi nezimpawu zomuntu, futhi izilonda ezingaphezu kwe-MRI akusho ukuthi ukukhubazeka okukhulu okuhlobene ne-MS.
Yingakho i-neurologist ijwayele ukugxila endleleni umuntu azizwa ngayo futhi esebenza ekuphileni kwabo kwansuku zonke. Ngamanye amazwi, ukuphatha isiguli, hhayi ukuthi yiziphi izivivinyo zabo noma izithombe zobuchopho ezibonisa.
Lokhu kusho ukuthi ucwaningo lubonisa ukuthi "izimbobo ezimnyama" zibonakala zihlotshaniswa noma zixhunyaniswa nokusebenza komuntu nokukhubazeka-kuleli phuzu, umonakalo wezinzwa nokubhujiswa kukhishwe ngaphandle.
