Ngaba uzive usoyika kancinci kwaye unexhala xa ugqirha wakho ekuxelela ukuba wenze i -MRI scan ? Kuqhelekile ukuba nemibuzo emininzi efana nale, "Ayisiyiyo le nto ingena ngaphakathi kumatshini omkhulu? Ngaba iza kuba buhlungu? Ngaba iza kuba yingxaki?" Yiyo loo nto namhlanje siza kuthetha ngale MRI scan ukuze siphendule yonke imibuzo onayo. Xa ugqiba ukufunda oku, uza kuba nokuqonda okucacileyo nge-MRI.
Ngamafutshane, yintoni le MRI?
I-MRI imele iMagnetic Resonance Imaging . Ngamafutshane, luvavanyo olusebenzisa amandla emagnethi anamandla, amaza erediyo, kunye nekhompyutha ukuvelisa imifanekiso ecacileyo neneenkcukacha zezitho kunye nezicubu ezingaphakathi emzimbeni wakho.
Ngoku usenokuba ucinga ukuba i-CT scan yenza into efanayo. Ewe, zombini zijonga ngaphakathi emzimbeni. Kodwa kukho umahluko omkhulu phakathi kwezi zimbini.
- I-CT Scan: Oku kusebenzisa iteknoloji ye-X-ray. I-CT scan idla ngokwenziwa ukukhangela izinto ezifana nokuqhekeka kwamathambo , iithumba, kunye nokuxilongwa ngokukhawuleza xa kufuneka kwimeko engxamisekileyo. Kuba iziphumo zingafunyanwa kwimizuzu eli-10 nje kuphela. Ikwabiza kancinci kune-MRI. Nangona kunjalo, i-CT scan ikubeka kwindawo enokusasazeka kwemitha .
- I-MRI Scan: Oku kunokuvelisa imifanekiso ecacileyo neneenkcukacha ezingaphezulu kune-CT scan. I-MRI ibaluleke kakhulu ekujongeni izicubu ezithambileyo ezifana nobuchopho, umqolo , izihlunu kunye nemisipha. Okubaluleke kakhulu, i-MRI ayisebenzisi ii-X-ray okanye eminye imitha eyingozi. Ke ngoko, luvavanyo olukhuselekileyo kakhulu. Nangona kunjalo, i-scan ithatha ixesha, mhlawumbi malunga neyure.
Isebenza njani i-MRI machine?
Cinga ngomatshini we-MRI njengomagnethi onamandla kakhulu, omile okwe-culvert enkulu. Xa uthunyelwa kumatshini, intsimi yemagnethi ibangela ukuba amasuntswana amancinci abizwa ngokuba zii-protons kwiimolekyuli zamanzi emzimbeni wakho ahambelane. Emva koko umatshini ukhupha amaza erediyo. Amasuntswana aqala ukujikeleza. Xa amaza erediyo ema, amasuntswana aqala ukujikeleza kwakhona. Xa oku kusenzeka, amasuntswana akhupha imiqondiso ekhethekileyo. Ikhompyutha ekumatshini ithatha loo miqondiso, iyihlalutye, kwaye idale umfanekiso ocacileyo wenxalenye yomzimba wakho ehlolwayo.
I-MRI enomahluko nangaphandle kwawo
Ngamanye amaxesha, ngaphambi kwe-MRI, kufakwa idayi ekhethekileyo (idayi engafaniyo) emthanjeni osengalweni yakho. Le dayi ivumela ugqirha ukuba abone ingaphakathi lomzimba wakho ngokucacileyo, ingakumbi umahluko phakathi kwezicubu eziphilileyo kunye nezicubu ezinomhlaza. Ngokuqhelekileyo, oku kwenziwa ngohlobo lwedayi olubizwa ngokuba yi-gadolinium. Le dayi inokubangela incasa encinci yesinyithi emlonyeni wakho xa ifakwa.
Nangona kunjalo, eli yeza alinikwa yonke i-MRI. Kwiimeko ezininzi, imifanekiso ecacileyo inokufumaneka ngaphandle kwalo. Kwakhona, eli yeza lokwahlulahlula alisetyenziswa kubafazi abakhulelweyo kunye nabo banesifo sezintso ngenxa yeengxaki ezinokubangela.
Ziziphi izifo ezinokufunyaniswa nge-MRI scan?
I-MRI scan sisixhobo esibaluleke kakhulu esisetyenziselwa ukufumanisa isifo okanye ukwenzakala, kunye nokubona indlela umzimba wakho osabela ngayo kunyango. I-MRIs inokwenziwa kwiindawo ezahlukeneyo zomzimba.
| Ilungu lomzimba | Iimeko ezifunyenwe yi-MRI |
|---|---|
| Ubuchopho kunye neNtambo yoMgogodla | Ukonakala kwemithambo yegazi engqondweni (njenge-aneurysm), istroke, umhlaza wobuchopho, i-multiple sclerosis (MS), ukwenzakala komqolo, iingxaki zamehlo nezendlebe zangaphakathi. |
| Intliziyo | Ukuvaleka kwemithambo yegazi, ukonakala kwemisipha yentliziyo, isifo sentliziyo, iingxaki zesakhiwo sentliziyo, ukudumba kwenwebu ejikeleze intliziyo (pericarditis). |
| Amathambo kunye namalungu | I-arthritis, usulelo lwamathambo, umhlaza, umonakalo wamalungu, iingxaki zeediski, iintlungu zentamo kunye nomqolo ezinxulumene nemithambo-luvo. |
| Isifuba | Ukuhlola abo basengozini enkulu yokuba nomhlaza webele, ukujonga ubungakanani kunye nokusasazeka komhlaza, kunye nokujonga umonakalo kwi-implants zebele. |
| Isibindi, Izintso, I-Pancreas | Umhlaza wesibindi okanye wepancreas, isifo sokuqina kwesibindi, ihepatitis, umhlaza wezintso, isifo sezintso esingapheliyo, amatye okanye iithumba. |
| Iprostate, Amaqanda | Ukufumanisa ukuba ithumba elikwiprostate okanye kwi-ovary lingumhlaza okanye akunjalo. |
Uhlobo olukhethekileyo lwe-MRI, i-fMRI (i-Functional MRI) , lunokubonisa ukuba zeziphi iindawo zengqondo ezisebenzayo xa usenza umsebenzi. Oku kubaluleke kakhulu xa ucwangcisa utyando lwesifo sokuwa okanye iithumba zobuchopho.
Zithini iingozi ze-MRI?
I-MRI luvavanyo olukhuselekileyo, kodwa kukho izinto ezimbalwa ekufuneka uzazi.
Ii-Implants zeMetal kunye neMRI
Le yeyona nto ibalulekileyo nebalulekileyo ekufuneka uyiqwalasele. Umatshini we-MRI yimagnethi enamandla, ngoko ke unokuba yingozi ukuba unezinto zesinyithi ngaphakathi okanye ngaphandle komzimba wakho.
Ukuba unayo nayiphi na kwezi meko zilandelayo, qiniseka ukuba wazisa ugqirha kunye nabasebenzi be-MRI ngaphambi kokuba wenze i-MRI:
- Isixhobo sePacemaker okanye i-ICD
- Iikliphu ze-aneurysms yobuchopho
- Iivalvu zentliziyo zokwenziwa
- Ii-implants ze-Cochlear
- Iziqwenga zeembumbulu okanye ezinye iziqwenga zesinyithi emzimbeni
- Amalungu, iiphini, okanye izikrufu ezenziweyo
- Izinto zokuzalisa amazinyo/i-braces – Ezi azisoloko ziyingxaki, kodwa kulungile ukuba uqaphele.
- Ukubhoboza umzimba
Nangona uninzi lwee-pacemakers ezintsha kunye nee-implants zenzelwe ukuba zihambelane ne-MRI, ezindala zinokonakala.Kubaluleke kakhulu kukhuseleko lwakho ukuxelela yonke into ngaphandle kokufihla nantoni na.
Ukukhulelwa kunye neMRI
I-MRI ayenziwa ngexesha le-trimester yokuqala yokukhulelwa ngaphandle kokuba kuyimfuneko ngokupheleleyo. Oku kungenxa yokuba amalungu omntwana ayakhula ngeli xesha. Emva koko, ingenziwa ngengcebiso kagqirha wakho. Ukuba umama oncancisayo unikwa idayi echasene nobisi, inani elincinci kakhulu layo lingadlula kubisi lwakhe lwebele. Nangona kungakhange kuqinisekiswe ukuba iyingozi, ukuba uneengxaki, ungafuna ukuphepha ukuncancisa umntwana wakho iiyure ezingama-24 emva kokuhlolwa kwaye ukhuphe ubisi lwebele. Thetha nogqirha wakho ngale nto.
Ulungiselela njani i-MRI?
Ngaphambi kokuba wenze i-MRI, kufuneka wenze amalungiselelo amancinci kwicala lakho.
Izinto ekufuneka uzixelele ugqirha ngaphambi kokuba uhlolwe:
- Ukuba uneengxaki zempilo, ezinje ngesifo sezintso okanye sesibindi.
- Ukuba ukhulelwe okanye ungakhulelwa.
- Ukuba unayo nayiphi na i-allergies , ingakumbi xa udibanisa imidiya.
- Ukuba unezifakelo zesinyithi emzimbeni wakho (izinto esithethe ngazo ngaphambili).
- Ukuba uyoyika iindawo ezincinci ezivalekileyo (i-claustrophobia) , unganikwa umatshini we-MRI ovulekileyo okanye umatshini wokuthomalalisa umzimba.
- Ukuba unetattoo , baxelele ngazo kuba ezinye iintlobo zeinki zinokuba neentsimbi.
Ngomhla wokuskena...
Akuvumelekanga ukuzisa naziphi na izinto zesinyithi kwigumbi le-MRI, ngoko khumbula ukususa yonke into ngaphambi kokuba uye kwi-scan.
- Ubucwebe, iiwotshi, amacici
- I-Underwire bra
- Iipinki zeenwele, iibhegi, iingqekembe
- Amakhadi etyala (intsimi yemagnethi inokucima idatha kwezi)
- Iifowuni eziphathwayo
- Iiglasi, amazinyo okufakelwa
Ngokwesiqhelo uza kunikwa ilokhwe yesibhedlele oza kuyinxiba.
Kwenzeka ntoni ngexesha nasemva kweskeni?
Uza kulala ebhedini uze ungeniswe kancinci kumatshini we-MRI. Iintambo zingasetyenziselwa ukukugcina ungashukumi. Ngexesha lokuskena, ingcali iza kukujonga kwigumbi elahlukileyo.
Ngelixa umatshini usebenza, uya kuva isandi esikhulu sokucofa okanye sokucofa . Esi sisandi somatshini esivelisa amandla okuthatha imifanekiso. Musa ukothuka siso sandi. Uya kunikwa ii-earplugs okanye ii-earmuffs ukunciphisa ingxolo. Ngamanye amaxesha, unokuziva urhawuzelelwa kancinci ngexesha lokuskena ngenxa yokuvuselelwa kwemithambo-luvo emzimbeni wakho. Oku kuqhelekile.
Iskeni ingathabatha naphi na ukusuka kwimizuzu eli-15 ukuya kwengama-90, kuxhomekeke kwilungu lomzimba elihlolwayo.
Nje ukuba iskeni iphelile, ungaya ekhaya njengesiqhelo. Nangona kunjalo, ukuba unikwe ipilisi yokulala, kuya kufuneka uhlale esibhedlele ude uvuke ngokupheleleyo, kwaye kuya kufuneka umntu akuse ekhaya.
Umyalezo Wokuya Ekhaya
- I-MRI scan luvavanyo olungena-radioactive, olukhuselekileyo kakhulu, nolucacileyo lomfanekiso.
- Qiniseka ukuba wazisa ugqirha kunye nabasebenzi ngaphambi kokuba uskene ngazo naziphi na izinto zesinyithi ezingaphakathi okanye ezingaphandle komzimba wakho (ii-pacemakers, ii-pins, amalungu angengowokwenziwa).
- Kubalulekile ukutyhila naziphi na izinto ezikubangela ukuba ungabi namdla kwizinto ezithile, isifo sezintso, okanye ukuba ukhulelwe.
- Musa ukoyikiswa ziingxolo ezinkulu kunye nokungcangcazela okuncinci okuvayo ngaphakathi kumatshini. Ezi ziqhelekile.
- Ukuba uyoyika iindawo ezincinci (i-claustrophobia), sazise kwangaphambili kwaye uxoxe ngeendlela onokukhetha kuzo.
- Ukuba uneengxaki okanye amathandabuzo, ungaze ungathandabuzi ukubuza ugqirha wakho ngaphambi kokuba uhlolwe.
