Ingabe uzizwe wesaba futhi wethukile kancane lapho udokotela wakho ekutshela ukuthi wenze i -MRI scan ? Kujwayelekile ukuba nemibuzo eminingi efana nokuthi, "Akuyona yini into engena emshinini omkhulu? Ingabe izolimaza? Ingabe kuzoba yinkinga?" Yingakho namuhla sizoxoxa ngale MRI scan ukuze sicacise yonke imibuzo onayo. Ngesikhathi uqeda ukufunda lokhu, uzobe usuyiqonda kahle i-MRI.
Kalula nje, iyini le MRI?
I-MRI imele i-Magnetic Resonance Imaging . Kalula nje, iyisivivinyo esisebenzisa insimu enamandla yamagnetic, amaza omsakazo, kanye nekhompyutha ukukhiqiza izithombe ezicacile nezinemininingwane yezitho nezicubu zomzimba wakho.
Manje ungase ucabange ukuthi i-CT scan yenza into efanayo. Yebo, zombili zibheka ngaphakathi emzimbeni. Kodwa kunomehluko omkhulu phakathi kwalokhu okubili.
- I-CT Scan: Lokhu kusebenzisa ubuchwepheshe be-X-ray. I-CT scan ivame ukwenziwa ukuze kubhekwe izinto ezifana nokuphuka kwamathambo , izimila, kanye nalapho kudingeka ukuxilongwa okusheshayo esimweni esiphuthumayo. Ngoba imiphumela ingatholakala ngemizuzu eyi-10 nje kuphela. Futhi ishibhile kune-MRI. Kodwa-ke, i-CT scan ikuveza emisebeni .
- I-MRI Scan: Lokhu kungaveza izithombe ezicacile nezinemininingwane eminingi kune-CT scan. I-MRI ibaluleke kakhulu ekubhekeni izicubu ezithambile njengobuchopho, umgogodla , imisipha, kanye nemisipha. Okubaluleke kakhulu, i-MRI ayisebenzisi i-X-ray noma eminye imisebe eyingozi. Ngakho-ke, kuwukuhlolwa okuphephile kakhulu. Kodwa-ke, ukuskena kuthatha isikhathi, mhlawumbe cishe ihora.
Usebenza kanjani umshini we-MRI?
Cabanga ngomshini we-MRI njengomagnethi onamandla kakhulu, ome njenge-culvert enkulu. Uma uthunyelwa emshinini, insimu yamagnetic ibangela ukuthi izinhlayiya ezincane ezibizwa ngokuthi ama-proton kuma-molecule amanzi emzimbeni wakho zivumelane. Umshini ube usukhipha amaza omsakazo. Izinhlayiya bese ziqala ukujikeleza. Lapho amaza omsakazo ema, izinhlayiya ziqala ukuhambisana futhi. Uma lokhu kwenzeka, izinhlayiya zikhipha izimpawu ezikhethekile. Ikhompyutha emshinini ithatha lezo zimpawu, izihlaziye, futhi idale isithombe esicacile sengxenye yomzimba wakho ehlolwayo.
I-MRI enomehluko nangaphandle kwawo
Ngezinye izikhathi, ngaphambi kwe-MRI, kufakwa idayi ekhethekile (idayi yokungafani) emthanjeni osengalweni yakho. Le dayi ivumela udokotela ukuthi abone ingaphakathi lomzimba wakho ngokucacile, ikakhulukazi umehluko phakathi kwezicubu ezinempilo nezicubu ezinomdlavuza. Ngokuvamile, lokhu kwenziwa ngohlobo lwedayi olubizwa ngokuthi i-gadolinium. Le dayi ingabangela ukunambitheka okuncane kwensimbi emlonyeni wakho uma ifakwa.
Kodwa-ke, lo muthi awunikezwa kuyo yonke i-MRI. Ezimweni eziningi, izithombe ezicacile zingatholakala ngaphandle kwawo. Futhi, lo muthi wokuqhathanisa awusetshenziswa kwabesifazane abakhulelwe nalabo abanesifo sezinso ngenxa yezinkinga ezingabangelwa yiwo.
Yiziphi izifo ezingatholakala nge-MRI scan?
I-MRI scan iyithuluzi elibaluleke kakhulu elisetshenziselwa ukuxilonga isifo noma ukulimala, kanye nokubona ukuthi umzimba wakho usabela kanjani ekwelashweni. I-MRI ingenziwa ezingxenyeni ezahlukene zomzimba.
| Ingxenye yomzimba | Izimo ezitholwe yi-MRI |
|---|---|
| Ubuchopho Nomgogodla | Ukulimala kwemithambo yegazi ebuchosheni (njenge-aneurysm), isifo sohlangothi, umdlavuza wobuchopho, i-multiple sclerosis (MS), ukulimala komgogodla, izinkinga zamehlo nendlebe yangaphakathi. |
| Inhliziyo | Imithambo yegazi evalekile, umonakalo wenhliziyo, isifo senhliziyo, izinkinga zesakhiwo enhliziyweni, ukuvuvukala kolwelwesi oluzungeze inhliziyo (i-pericarditis). |
| Amathambo Namalunga | I-arthritis, izifo zamathambo, umdlavuza, ukulimala kwamalunga, izinkinga zamadiski, ubuhlungu bentamo nomhlane obuhlobene nemizwa. |
| Isifuba | Ukuhlola labo abasengozini enkulu yomdlavuza webele, ukuhlola ubukhulu nokusabalala komdlavuza, kanye nokuhlola umonakalo kuma-implants amabele. |
| Isibindi, Izinso, I-Pancreas | Umdlavuza wesibindi noma we-pancreatic, i-cirrhosis, i-hepatitis, umdlavuza wezinso, isifo sezinso esingamahlalakhona, amatshe noma izimila. |
| I-Prostate, Ama-Ovaries | Ukunquma ukuthi isimila ku-prostate noma ku-ovary sinomdlavuza noma cha. |
Uhlobo olukhethekile lwe-MRI, i-fMRI (i-Functional MRI) , lungabala ukuthi yiziphi izingxenye zobuchopho ezisebenzayo lapho wenza umsebenzi. Lokhu kubaluleke kakhulu lapho uhlela ukuhlinzwa kwesifo sokuwa noma izimila zobuchopho.
Ziyini izingozi ze-MRI?
I-MRI ngokuvamile iyisivivinyo esiphephile kakhulu, kodwa kunezinto ezimbalwa okufanele uzazi.
Izimila Zensimbi kanye ne-MRI
Lena yinto ebaluleke kakhulu futhi ebaluleke kakhulu okufanele uyinake. Umshini we-MRI unamandla amakhulu, ngakho-ke kungaba yingozi uma unezinto zensimbi ngaphakathi noma ngaphandle komzimba wakho.
Uma unezinye zezimo ezilandelayo, qiniseka ukuthi wazisa udokotela kanye nabasebenzi be-MRI ngaphambi kwe-MRI:
- I-Pacemaker noma idivayisi ye-ICD
- Iziqeshana ze-aneurysms yobuchopho
- Ama-valve enhliziyo okwenziwa
- Izimila ze-Cochlear
- Izingcezu zezinhlamvu noma ezinye izingcezu zensimbi emzimbeni
- Amalunga, amaphini, noma izikulufo zokwenziwa
- Ukugcwalisa amazinyo/izinsingo zokubopha amazinyo – Lokhu ngokuvamile akuyona inkinga, kodwa kuhle ukuqaphela.
- Ukubhoboza umzimba
Nakuba ama-pacemaker amaningi amasha kanye nama-implant aklanyelwe ukuhambisana ne-MRI, amadala angonakala. Ngakho-ke,Kubaluleke kakhulu ekuphepheni kwakho ukutshela konke ngaphandle kokufihla lutho.
Ukukhulelwa kanye ne-MRI
I-MRI ayenziwa ngesikhathi se-trimester yokuqala yokukhulelwa ngaphandle kokuthi kudingekile ngempela. Lokhu kungenxa yokuthi izitho zomntwana ziyakhula phakathi nalesi sikhathi. Ngemva kwalokho, kungenziwa ngeseluleko sikadokotela wakho. Uma umama oncelisayo enikwa idayi engafani, inani elincane kakhulu layo lingadlulela ebisini lakhe lebele. Nakuba kungakaze kutholakale ukuthi liyingozi, uma unenkinga, ungase ufune ukugwema ukuncelisa ingane yakho amahora angama-24 ngemva kokuskena bese ukhipha ubisi lwebele. Khuluma nodokotela wakho ngalokhu.
Ulungiselela kanjani i-MRI?
Ngaphambi kwe-MRI, udinga ukulungiselela kancane.
Izinto okufanele uzitshele udokotela ngaphambi kokuskena:
- Uma unezinkinga zempilo, njengesifo sezinso noma sesibindi.
- Uma ukhulelwe noma ungase ukhulelwe.
- Uma une- allergies , ikakhulukazi uma uqhathanisa imidiya.
- Uma unezitho zomzimba zensimbi emzimbeni wakho (izinto esikhulume ngazo ngaphambili).
- Uma wesaba izikhala ezincane ezivalekile (i-claustrophobia) , unganikezwa umuthi wokudambisa noma umshini we-MRI ovulekile.
- Uma unemidwebo , mtshele ngayo ngoba ezinye izinhlobo zikayinki zingase zibe nezinsimbi.
Ngosuku lokuskena...
Akuvunyelwe ukuletha noma yiziphi izinto zensimbi egumbini le-MRI, ngakho khumbula ukususa konke ngaphambi kokuya ku-scan.
- Ubucwebe, amawashi, amacici
- I-Underwire bra
- Izikhonkwane zezinwele, izikhwama zemali, izinhlamvu zemali
- Amakhadi esikweletu (insimu yamagnetic ingasula idatha kulawa)
- Omakhalekhukhwini
- Izibuko, amazinyo okufakelwa
Ngokuvamile uzonikezwa ingubo yasesibhedlela ozoyigqoka.
Kwenzekani ngesikhathi nangemva kokuskena?
Uzolala embhedeni bese ufakwa kancane kancane emshinini we-MRI. Amabhande angasetshenziswa ukukugcina unganyakazi. Ngesikhathi sokuskena, uchwepheshe uzokuqapha esegumbini elihlukile.
Ngesikhathi umshini usebenza, uzozwa umsindo wokuchofoza noma wokushaya kakhulu . Lona umsindo womshini okhiqiza amandla okuthatha izithombe. Ungakhathazeki ngalowo msindo. Uzonikezwa ama-earplug noma ama-earmuff ukunciphisa umsindo. Ngezinye izikhathi, ungase uzizwe umuzwa omncane wokuthuthumela ngesikhathi sokuskena ngenxa yokuvuselelwa kwemizwa emzimbeni wakho. Lokhu kuvamile.
Ukuskena kungathatha noma yikuphi kusukela emizuzwini eyi-15 kuya kwengama-90, kuye ngokuthi ingxenye yomzimba ihlolwa kanjani.
Uma ukuskena sekuphelile, ungaya ekhaya njengokujwayelekile. Kodwa-ke, uma unikezwe iphilisi lokulala, kuzodingeka uhlale esibhedlela uze uvuke ngokuphelele, futhi uzodinga othile ozokuthatha akuyise ekhaya.
Umlayezo Wokuya Nawe Ekhaya
- Ukuskena kwe-MRI kuwukuhlolwa kwesithombe okungenamisebe, okuphephile kakhulu, futhi okucacile.
- Qiniseka ukuthi wazisa udokotela nabasebenzi ngaphambi kokuskena nganoma yiziphi izinto zensimbi ezingaphakathi noma ngaphandle komzimba wakho (ama-pacemaker, ama-pin, amalunga okwenziwa).
- Kubalulekile ukudalula noma yikuphi ukungezwani komzimba onakho, isifo sezinso, noma uma ukhulelwe.
- Ungakhathazeki ngemisindo emikhulu kanye nokudlidliza okuncane okuzwayo ngaphakathi komshini. Lokhu kujwayelekile.
- Uma wesaba izindawo ezincane (i-claustrophobia), sazise kusenesikhathi bese uxoxa ngezinketho.
- Uma unemibuzo noma ukungabaza, ungalokothi unqikaze ukubuza udokotela wakho ngaphambi kokuskena.
I-MRI, i-MRI, iskena, iskena sobuchopho, idayi yokuhlukanisa, i-magnetic resonance imaging, ukuhlolwa kwezokwelapha, ukuxilongwa
