Ukuqonda Ukuthola Okuvamile kwi-Brain MRI
Uma udokotela wakho ekutshela ukuthi kukhona "amabala" emfanekisweni we-resonance magnetic (MRI) wengqondo yakho, ukusabela kwakho kokuqala kungase kuvelele. Kodwa kufanele ukhathazeke kanjani ngalezi zinguquko ezimhlophe? Ayikho isiqondiso esamukeleka kabanzi kulokho "okunamandla kakhulu," nakuba iningi lezinzwa zezinzwa zinezifiso zabo siqu. Amanye amazinga kulezi zinguquko kulindeleke eneminyaka yobudala. Ngokungazinaki lezi zilonda, Nokho, akuyona inkambo engcono kakhulu yokusebenza.
Yiziphi Amabala Amhlophe E-Brain MRI?
Lezi zindawo zingase zibhekwe njengezinto ezingaziwa ezingabonakali (UBO), izindawo eziphezulu zamandla ezibonakaliso (HSIA), ama-hyperintensities emhlophe, kanye nezinguquko ezimhlophe zendaba emhlophe. Udaba olumhlophe oluthiwa luvame ukutholakala eduze kwe- ventricles , futhi njengoba igama lisho ukuthi, litholakala emcimbini omhlophe wengqondo. Ziyabonakala kakhulu ku- T2 izikali ezilinganiselwe.
Yini Ebangela Amachashazi Ama-White MRI?
Udaba olumhlophe olungavamile luyashintsha kaningi lunezizathu ezingaphezu kweyodwa. Lezi zinguquko ziye zahlotshaniswa nezinkinga ezifana nokushaya , ukuncipha kwengqondo, ukucindezeleka, nokusebenza komzimba, njengokuhamba. Akucaci ukuthi lezi zilonda empeleni zibangela lezi zinkinga, noma kunjalo. Bangase basho nje isimo esincane sokunciphisa impilo yobuchopho jikelele.
Ngokufanayo, izifo zempilo yengqondo ezinjenge- high blood pressure (ukucindezeleka komfutho wegazi) nazo zanda ngokukhula. Njengoba ukhula, izitsha zakho zegazi zivame ukuba nzima futhi zibe mncane. Lokhu kunciphisa kungaholela ezinkingeni zenhliziyo ezifana ne-infarction ye-myocardial noma izinkinga zobuchopho ezinjenge-stroke.
Ingabe Lezi Izinguquko Ezifana Neziphapho Ezilile?
I-hyperintensities ebuchosheni bakho cishe ezindaweni ezizobangelwa ukuncipha kwegazi. Kunokuphikisana mayelana nokuthi ukugeleza kunganciphisa kanjani. Abanye baye babheka izilonda njengezingxabano ezincane ezingakaze zenze izimpawu, ngokumelene nokushaywa okugcwele, lapho ukucindezeleka kwegazi kuphele ngokuphelele futhi kuphele ngokuphelele. Uma ukugeleza kwegazi kuhamba kancane esikhundleni sokuma ngenxa yenguquko yendawo ekucindezelekeni kwegazi, lezi zifunda zobuchopho bakho zizohamba kancane kancane futhi zihlale zinciphisa umoya wayo.
Yini Eyandisa Ingozi Yalezi Izinguquko Zomsindo?
Uma une-hypertension, ubhema, noma uphuze utshwala obukhulu, usengozini yokunciphisa umzimba. Isifo sikashukela nokukhuluphala kwandisa futhi ingozi yakho ye-vascular. Udaba oluphezulu lwama-hyperintensities luye lwahlanganiswa nazo zonke lezo zinto eziyingozi. Ngokufanayo, izici ezivikela imithwalo yegazi, njengokudla okunempilo nokuzivocavoca, zihlotshaniswa nezinguquko ezincane ezimhlophe ebuchosheni njengoba sikhula.
Njengezinye izibonakaliso eziningi zesifo se-vascular, abanye abantu basengozini kakhulu yalezi zinguquko zomsindo ku-MRI kunabanye. Uma ungumuntu waseSpanishi noma wase-Afrika waseMelika, kungenzeka ukuthi unezilonda kunabanye abantu. Abesifazane bavame ukuba nezindaba ezimhlophe ezingaphezu kwamadoda, futhi.
Kukhona lapho kunesilinganiso esithile sokufaneleka kulezi zilonda. Izakhi zofuzo eziningi ziye zahlotshaniswa nalezi zinguquko, nakuba kungacacile ukuthi zihlobene kanjani.
Ngenkathi uguquko oluthile lwezinguquko ezimhlophe kulindeleke uma uneminyaka yobudala, lokho akusho ukuthi lezi zinguquko zishintsha ngokuphelele. Ukwandiswa kwezidakamizwa ezimhlophe ezihlobene nomhlophe kuhlotshaniswa nengozi ephezulu yokushaywa yisifo socansi kanye nokuwohloka komqondo , kanye nokufa okuphezulu ngokujwayelekile. Izilonda ngokwazo cishe azibangela izinkinga. Esikhundleni salokho, izici eziyingozi ezibangelwa izilonda zandisa amathuba okuthuthukisa izinkinga ngaphakathi nangaphandle kwesistimu yezinzwa.
Indlela Yokumisa Amachashazi Ekudambiseni
Udokotela wakho angakusiza uqonde okutholakele kwakho kwe-MRI okungcono kakhulu. Esikhundleni sokugxila kulezi zindlela ezingenakuqhathaniswa, udokotela wakho angakusiza ukuthi ubone ukuthi yiziphi izinto ezingase zidingeke ukubhekana nazo. Ukudla kwakho kungahle kube ngcono yini? Ingabe udinga ukusebenzisa okuningi?
Lapho ubheka ukuthi iziphi izinto ezibonakala zihambisana kakhulu nalezi zindawo ebuchosheni, ukucindezeleka kwegazi okubonakala sengathi kuhlobene kakhulu. Kodwa-ke, ucwaningo luye lwaba nemiphumela ehlangene mayelana nendlela yokuphatha kangcono ukucindezelwa kwegazi ngenxa yalezi ziphumo ze-MRI. Ezinye izifundo zibonisa ukuthi ukuphathwa kwengcindezi yegazi kusiza, kanti abanye abakhombisi inzuzo ecacile.
Yini Okulandelayo?
Ukuxoshwa kwezindaba ezimhlophe ukutholakala okuvame kakhulu embukisweni we-MRI, ikakhulukazi kubantu asebekhulile. Kodwa-ke, ngenxa yokuthi lezi zindawo zivamile akusho ukuthi zishintsha ngokuphelele. Ukuba nenani elikhudlwana le-hyperintensities lihlotshaniswe nesifo sohlangothi, ukucindezeleka, nezinye izinkinga.
Isizathu salezi zinguquko siyinkimbinkimbi, kodwa kungenzeka ukuthi sibhekisela ekuguqulweni kwezinguquko ezingaba nomthelela ngokulandela uhlobo lwezeluleko esazi ukuthi kufanele sizilandele noma kunjalo. Gcina ukucindezelwa kwegazi ngaphansi kokulawula, udle kahle, uvivinye umzimba, ugweme ukubhema futhi uphuze utshwala ngokulinganisela. Ngokulandela lesi seluleko, awukwazi ukulungisa kuphela amabala kwi-MRI yakho kodwa okubaluleke kakhulu, gcina ubuchopho bakho nomzimba wonke uphile.
Izwi elivela
Kungaba ukwesaba ukuzwa ukuthi kukhona okutholakala ku-scans yakho okusho ukuthi usenezingozi ezingaphezulu. Kodwa kunezinyathelo ongazithatha ukuze unciphise izingozi zakho futhi uthuthukise amathuba okuba nempilo enhle.
