Khawuthelekelele umhlobo wakho etyandwa ukuze kususwe ithumba kwindawo entsonkothileyo engqondweni yakhe. Oogqirha balumkile kakhulu ekwenzeni utyando. Kodwa bazi njani ngokuqinisekileyo ukuba ithumba lisusiwe ngokupheleleyo okanye ukuba kukho iqhekeza elincinci eliseleyo? Emva kotyando, ukuba uphinde wenze iskeni emva kweentsuku ezimbalwa, ungazi ngokuqinisekileyo. Ukuba kukho neqhekeza elincinci eliseleyo, kuya kufuneka wenze olunye utyando, akunjalo? Le teknoloji ikhethekileyo esithetha ngayo namhlanje isetyenziswa njengesisombululo kwiingxaki ezinjalo.
Ngamafutshane, yintoni i-iMRI?
Igama elipheleleyo le-iMRI yi -Intraoperative Magnetic Resonance Imaging . Igama elithi "Intraoperative" lithetha "ngexesha lotyando." Oku kuthetha ukuba yi -MRI scan eyenziwa ngelixa kusenziwa utyando . Oku kuvumela iqela lakho lotyando ukuba libone amalungu omzimba, izicubu, kunye nezinye izinto ngaphakathi emzimbeni wakho ngokucacileyo ngelixa kusenziwa utyando.
Khawucinge ngogqirha esusa ithumba ebuchotsheni. Angenza i-MRI scan emva kokuba ithumba lisusiwe, ngaphambi kokuba utyando lugqitywe, ukuze abone ukuba, "Ndilisusile lonke ithumba? Okanye kusekho amaqhekeza amancinci aseleyo?" Ukuba i-scan ibonisa ukuba kukho iqhekeza elincinci eliseleyo, angayisusa loo nxalenye ngoko nangoko.
Eyona nzuzo inkulu yoku kukuba ukwazi ukuba kukho iindawo ezithile zethumba ezisele emva kotyando kunokunciphisa kakhulu umngcipheko wokuba kwenziwe utyando lwesibini.
Yintoni umahluko phakathi kwe-MRI eqhelekileyo kunye ne-iMRI?
Umahluko ophambili nokuphela kwawo phakathi kwezi zimbini lixesha elithathwayo ukukwenza .
- I-MRI eqhelekileyo: Oku kwenzelwa ukufumanisa isifo okanye ukucwangcisa utyando. Ungena kumatshini we-MRI njengesiqhelo uze wenze olu vavanyo.
- I-iMRI: Oku kwenziwa ngelixa kusenziwa utyando , ngaphakathi kwigumbi lotyando.
Ngamafutshane, enye yenziwa ngaphambi kotyando, kwaye enye yenziwa ngexesha lotyando ngokwalo.
Kutheni oogqirha besebenzisa obu buchwephesha ngexesha lotyando?
Ezinye iindlela zotyando, ingakumbi ezobuchopho, zinzima kakhulu. Nokuba ngumahluko wemilimitha unokuba nefuthe elikhulu. Ugqirha ufuna umfanekiso ocacileyo nocacileyo ngexesha lotyando kunalowo banokuwubona ngamehlo abo okanye ngemakroskopu. Kulapho ixabiso le-iMRI licaca khona.
Nazi ezinye zeendlela ezisetyenziswa kakhulu yiteknoloji ye-iMRI:
| Uhlobo lotyando | Uncedo oluvela kwi-iMRI |
|---|---|
| Ukususwa kweTumor yoBuchopho | Ukuqinisekisa ukuba ithumba lisusiwe ngokupheleleyo na, okanye ukuba ezinye iindawo zingasuswa ngaphandle kokonakalisa izicwili eziphilileyo. Oku kubaluleke kakhulu kwiithumba ezifana ne -glioma . |
| Ithumba lepituitary | Xa ususa iithumba ezijikeleze i-pituitary gland, inxalenye ebuthathaka kakhulu yobuchopho, ukujonga umonakalo kwimithambo-luvo ebalulekileyo kunye nemithambo yegazi ekufutshane. |
| Ukukhuthazwa koBuchopho obuNzulu (i-DBS) | Xa ufaka ii-electrode nzulu engqondweni kwiimeko ezifana nesifo sikaParkinson , ukuqinisekisa ukuba zibekwe kwindawo efanelekileyo. |
| Utyando lwe-Epilepsy | Ukuchonga ngokuchanekileyo indawo engaqhelekanga yengqondo ebangela isifo sokuwa nokujonga ukuba isusiwe ngokupheleleyo na. |
| I-craniotomy | Kuyo nayiphi na ityando elinzima elibandakanya ingqondo, ukujonga imeko yengqondo (ukudumba, ukopha) ekupheleni kotyando. |
Isebenza njani le matshini ye-iMRI?
I-MRI scan ngumatshini osebenzisa iimagnethi kunye namaza erediyo ukuthatha imifanekiso yangaphakathi yomzimba. Yiloo nto eyenzekayo kwi-iMRI. Awuyi kuyiva kuba uphantsi kwe-anesthesia kwaye uhlala ungazi nto kwaphela.
Nantsi indlela esebenza ngayo, yithi nje:
Ingaphezulu kwesiqingatha semizimba yethu yenziwe ngamanzi. Amanzi enziwe ngeeathom zehydrogen kunye neoksijini. Ngaphakathi kweli athom yehydrogen kukho isuntswana elibizwa ngokuba yiproton . Ezi protons zinombane, kwaye nazo ziyajikeleza.
Umatshini we-MRI uthumela amandla emagnethi anamandla emzimbeni wakho. Okwenzekayo kukuba zonke ezi protons emzimbeni wakho zilandelelana kwicala elinye, njengenaliti yekhampasi ejonge emantla.
Emva koko, umatshini we-MRI uthumela amaza amaza erediyo ngale magnethi. Oku kufana ne-shutter yekhamera ethatha umfanekiso. La maza erediyo aphazamisa ukulungelelana kweeprotoni okomzuzwana. Xa amaza erediyo ema, iiprotoni zibuyela kulungelelwano lwazo lwantlandlolo. Olu tshintsho luthathwa sisikena esikumatshini. Idatha ithunyelwa kwikhompyutha, edala umfanekiso ocacileyo onemilinganiselo emithathu (3D).
Ndingayilungiselela njani i-iMRI?
Enyanisweni, akufuneki ulungiselele i-iMRI kuba kwenzeka ngexesha lotyando lwakho. Okufuneka ukwenze kukulungiselela utyando lwakho ngokufanelekileyo. Landela imiyalelo kagqirha wakho njengoko aza kukuxelela.
Uza kuba phantsi kwe-anesthesia ngexesha lenkqubo, ngoko ke kusenokwenzeka ukuba ulele. Kuza kubakho ingxolo xa umatshini we-MRI usebenza, kodwa awuyi kuyiva ngenxa ye-anesthesia. Ngamanye amaxesha, kukho iinkqubo zokuvuka. Kwimeko ezinjalo, iqela lezonyango liza kukulungiselela le nkqubo kwaye liqinisekise ukuba ukhululekile ngexesha le-scan.
Izinto ekufuneka uzixelele ugqirha wakho ngaphambi kotyando:
- Oko kukuthi, ukuba ukhulelwe .
- Ukuba kukho into eyenziwe ngesinyithi emzimbeni wakho. Umzekelo, i-pacemaker, iipleyiti zesinyithi ezifakwe emzimbeni, amalungu okwenziwa, njl. Iimagnethi ezinamandla kwi-MRI zinokubangela ukuba ezi zinto zishukume okanye zingasebenzi kakuhle. Oku kuyingozi. Ke ngoko, ukuba uxelelwe ngale nto kwangethuba, iqela lezonyango liza kuthatha amanyathelo okhuseleko afunekayo.
- Ngaphambi kotyando, kufuneka ususe zonke izinto zesinyithi emzimbeni wakho, ezinje ngezacholo, amacici, iiphini zeenwele, kunye neengcingo zesinyithi ezikwimpahla yakho yangaphantsi .
Zithini iingenelo ze-iMRI?
Kukho iingenelo ezininzi ezibalulekileyo zokusebenzisa iteknoloji ye-iMRI.
- Imifanekiso ecacileyo kakhulu: Indawo yomzimba otyandwayo ibonakala ngokucacileyo nangokweenkcukacha.
- Ulwazi olufumaneka ngexesha langempela: Le mifanekiso inokubonwa ngexesha lotyando, nto leyo evumela ukuba kwenziwe izigqibo ngaphandle kokulibazisa.
- Ukuvavanya utshintsho: Ungabona kwangoko indlela indawo etshintshe ngayo ngexesha lotyando (umz. emva kokususwa kwethumba).
- Ukuthintela iingxaki: Le mifanekiso icacileyo inokunciphisa kakhulu iingxaki ezinokubakho emva kotyando.
- Ayisebenzisi imitha: Itekhnoloji ye-MRI ayisebenzisi imitha efana ne-X-ray okanye i-CT scans, ngoko ke ayilimazi umzimba.
Ugqirha unokuzibona ezi ziphumo kwimizuzwana embalwa emva kokuhlolwa, nto leyo emvumela ukuba aqhubeke nenyathelo elilandelayo lotyando ngaphandle kokulibazisa.
Umyalezo Wokuya Ekhaya
- I-iMRI yi-MRI scan ekhethekileyo eyenziwa ngexesha lotyando.
- Eyona njongo iphambili yoku kukunika oogqirha abenza utyando ithuba lokubona ngaphakathi emzimbeni ngokucacileyo baze baphile.
- Oku kunceda ukuqinisekisa ngoko nangoko ukuba ithumba lisusiwe ngokupheleleyo na, ingakumbi kwiindlela zotyando ezinzima ezifana nokususwa kwethumba ebuchotsheni.
- Oku kunciphisa kakhulu isidingo sotyando lwesibini.
- Ukuba uza kwenziwa utyando nge-iMRI, qiniseka ukuba wazisa ugqirha wakho kwangaphambili malunga nazo naziphi na izixhobo zesinyithi, ezifana ne-pacemakers, ozifakileyo emzimbeni wakho.
