I-MRI ngesikhathi sokuhlinzwa? Sikhuluma nge-Intraoperative MRI (iMRI)!

Wake wezwa ngendlela yokubona ngaphakathi emzimbeni wakho ngenkathi uhlinzwa ? Enye yalezi zindlela ezintsha ibizwa ngokuthi i-iMRI. Lokhu kuvumela odokotela abahlinzayo ukuthi babone okungaphakathi emzimbeni wakho ngokucacile ngenkathi wenza ukuhlinzwa. Akumangalisi yini? Ake sixoxe ngalokhu ngokuningiliziwe.

Iyini le iMRI?

Kalula nje, i-iMRI isifinyezo se- Intraoperative Magnetic Resonance Imaging . NgesiSinhala, isho ukuthi 'I-Magnetic Resonance Imaging eyenziwa ngesikhathi sokuhlinzwa'. Manje ungase ucabange ukuthi lokhu kuyinkimbinkimbi kancane. Kodwa ungakhathazeki, ngizokuchaza kalula. Cabanga ukuthi ithimba lakho lokuhlinzwa lenza ukuhlinzwa , futhi ngesikhathi esifanayo, benza ukuskena okukuvumela ukuthi ubone kahle izitho nezicubu zomzimba wakho. Yilokho i-iMRI eyikho.

Lokhu kunenzuzo enkulu. Isibonelo, ake sithi isimila sobuchopho siyasuswa. Ngale iMRI, udokotela ohlinzayo angabona kahle ukuthi isimila sisusiwe ngokuphelele noma ukuthi kukhona yini ingxenye encane esele. Uma sisuswa, khona-ke kungase kudingeke benze olunye ukuhlinzwa. Lokhu kuwusizo kakhulu ukuvimbela izinto ezinjalo.

Uyini umehluko phakathi kwe-MRI ne-iMRI?

Manje ungase ucabange, 'O... i-MRI iyi-scan eyenziwa ngalowo mshini omkhulu, ngakho-ke ingabe i-iMRI iyinto efanayo?' Yebo, bobabili basebenzisa ubuchwepheshe obufanayo, obuwukuthatha izithombe zangaphakathi lomzimba besebenzisa amasimu kazibuthe namagagasi omsakazo. Kodwa umehluko omkhulu ukuthi kwenziwa nini .

I-MRI ejwayelekile (i-Magnetic Resonance Imaging) yenziwa ukuze kutholakale isifo noma kulungiselelwe ukuhlinzwa. Okusho ukuthi, udokotela wakho uzokunikeza i-MRI, bese uyahamba uyoyenza ngosuku oluhlukile. Kodwa-ke, i-iMRI yenziwa ngesikhathi senqubo yokuhlinzwa . Yilokho okwenza kube okukhethekile.

Kungani odokotela abahlinzayo besebenzisa i-iMRI?

Eqinisweni, okunye ukuhlinzwa kuyinkimbinkimbi kakhulu. Njengokusebenza ngemicu. Kulezo zimo, bekungeke yini kube usizo olukhulu uma ungabona ngokucacile okwenzekayo ngaphakathi emzimbeni ngenkathi kwenziwa ukuhlinzwa? Yilokho okwenziwa yi-iMRI. Ingabona ngokucacile ngisho nemininingwane emincane kakhulu ukuthi iso lomuntu noma imakroskopu ingabonwa.

Yiziphi izindlela zokuhlinzwa ezivame kakhulu ezisebenzisa i-iMRI?

Ubuchwepheshe be-iMRI buwusizo kakhulu ekuhlinzeni okudinga izinqubo ezibucayi nezicophelelayo. Nazi izibonelo ezimbalwa:

• Ukususa izimila zobuchopho: Lokhu kuyindlela evame kakhulu yokusetshenziswa kwe-MRI. Ubuchopho buyindawo ebucayi kakhulu. Lokhu kusiza ukususa isimila ngokuphelele ngaphandle kokulimaza izicubu zobuchopho ezinempilo. Lokhu kusebenza nasezimila ezitholakala endlaleni ye-pituitary.
• Ukuhlinzwa kwe-craniotomy:Lokhu kuhilela ukuvula ugebhezi nokufinyelela ebuchosheni. I-iMRI iyasiza kakhulu kulolu hlobo lokuhlinzwa.
• Ukufakelwa Kobuchopho Obujulile (i-DBS): Kulokhu kuhlinzwa, okwenziwa kubantu abanezifo zezinzwa njengesifo sikaParkinson, i-iMRI isiza ukubeka i-stimulator endaweni efanele.
• Ukususa uhlobo lomdlavuza wobuchopho olubizwa ngokuthi i-glioma.
• Ukuhlinzwa kwesifo sokuwa.

Isebenza kanjani i-iMRI?

Lokhu kungokwesayensi kancane, kodwa ngizozama ukukuchazela ngendlela elula. Ubuwazi ukuthi ngaphezu kwengxenye yemizimba yethu yakhiwe ngamanzi? Amanzi akhiwe ngama-athomu e-hydrogen ne-oxygen. Ngaphakathi kwale athomu ye-hydrogen, kunezinhlayiya ezincane ezibizwa ngokuthi ama-proton . Lawa ma-proton aneshaja kagesi, futhi ajikeleza ngaphakathi kwe-athomu njengomuthi ojikelezayo.

Uma ugesi udlula kuma-coil angaphakathi komshini we-MRI, kudalwa insimu yamagnetic yesikhashana emzimbeni wakho. Ifana nemagnethi enkulu. Bese kuthi, wonke lawo ma-proton emzimbeni wakho engiwakhulume ngawo aqondaniswe, abhekise kumagnethi emshinini we-MRI. Njengenaliti yekhampasi ekhomba enyakatho. Lokho kungenxa yensimu yamagnetic yoMhlaba.

Ngemuva kwalokho, umshini we-MRI uthumela amaza omsakazo ngale nsimu yamagnetic. Lokhu kusebenza njenge-camera shutter uma uthatha isithombe. Lawa maza omsakazo ashintsha okwesikhashana ukuhlelwa kwama-proton ayekulowo mugqa. Lapho amaza omsakazo ema, ama-proton azihlela kabusha. Lezo zinguquko zithathwa yi-scanner bese zithunyelwa kukhompyutha. Ikhompyutha isebenzisa leyo datha ukudala isithombe esisibonayo.

Ngeke uzizwe noma yikuphi kwalokhu ngoba ungaphansi kwe-anesthesia futhi mhlawumbe ulele kahle. Umshini we-MRI usegumbini elifanayo lokuhlinza lapho kwenziwa khona ukuhlinzwa, noma uhlelwe ngendlela yokuthi ukwazi ukuwufinyelela kalula.

Ingabe udinga ukulungiselela i-iMRI?

Akukho ukulungiselela okukhethekile okudingeka ukwenze nge-iMRI, njengoba kwenziwa ngesikhathi sokuhlinzwa kwakho. Ngakho-ke, ithimba lakho lokuhlinzwa lizokulungiselela wena kanye negumbi lokuhlinza lolu vivinyo uma isikhathi sifika. Okudingeka ukwenze nje ukulandela imiyalelo udokotela wakho akunikeza yona ngaphambi kokuhlinzwa kwakho.

Ake sifunde nge-anesthesia.

Uma une-MRI, ungaphansi kwe -anesthesia ejwayelekile . Lokhu kusho ukuthi ulele ngokuphelele. I-MRI ayibuhlungu, kodwa ingaba nomsindo omncane. Ngezinye izikhathi, kunezinqubo zokuvuka lapho ungalaliswa khona. Ngisho nakulezo zimo, ithimba lezokwelapha lizokulungiselela futhi liqinisekise ukuthi ukhululekile ngesikhathi sokuskena.

Qaphela izinto zensimbi!

Lokhu kubaluleke kakhulu!Imishini ye-MRI isebenzisa omaginethi abanamandla, ngakho-ke akunakuba khona insimbi ngaphakathi noma ngaphandle komzimba wakho.

Izinto okufanele uzitshele udokotela wakho ngaphambi kokuhlinzwa zifaka:

• Ukhulelwe?
• Ingabe unezinto zensimbi emzimbeni wakho? Isibonelo:
• I-pacemaker.
• Izimila - izingxenye zensimbi ezibekwa ezindaweni ezifana nedolo kanye nesinqe.
• Amalunga okwenziwa.
• Ezinye izinto zokugcwalisa amazinyo.
• Izingcezu zensimbi ezifakwe emzimbeni (isb., izingcezu zezinhlamvu).

Uma kukhona into efana nale, umphumela wamagnetic we-MRI ungabangela ukuthi lezo zingxenye zensimbi zinyakaze, zishise, noma zingasebenzi. Lokho kuyingozi kakhulu. Ngakho-ke uma utshela udokotela le mininingwane kusengaphambili, uzolandela izinqubo zokuphepha ezikhethekile futhi enze ukuhlinzwa kwakho ngokuphephile.

Futhi, kuzodingeka ususe zonke izinto zobucwebe nezinsimbi ozigqokile ngaphambi kokuhlinzwa. Kuzodingeka futhi ususe amacici, ama-bra angaphansi kwensimbi, kanye nezikhonkwane zezinwele.

Yiziphi izinzuzo ze-iMRI?

Kunezinzuzo eziningana iziguli ezingazithola kulobu buchwepheshe be-iMRI. Ake sibheke ukuthi ziyini:

• Indawo yomzimba ehlolwayo ingabukwa ngemininingwane ecacile: ungabona kahle ukuthi kwenzekani nokuthi inkinga ikuphi.
• Lolu lwazi lungabukwa ngesikhathi sangempela: okungukuthi, ungabona isimo samanje sokusebenza njengoba kwenzeka, hhayi njengokubuka iskeni esidala.
• Izinguquko endaweni ethintekile zingahlolwa ngesikhathi sokuhlinzwa: isibonelo, lapho kususwa isimila, ungabona ngokushesha ukuthi kungakanani okususiwe nokuthi kungakanani okusasele.
• Izinkinga zingavinjelwa futhi zincishiswe: Amathuba okuthi kudingeke kwenziwe ukuhlinzwa kwesibili ancishiswe kakhulu ngoba ukuhlinzwa kokuqala kungazama ukuxazulula inkinga ngokuphelele.
• Akukho misebe: Ngokungafani ne-X-ray noma i-CT scan, ama-MRI awasebenzisi imisebe. Ngakho-ke ngeke ikulimaze nganoma iyiphi indlela.

Udokotela uzoyithola nini imiphumela ye-iMRI?

Lokhu kubaluleke kakhulu futhi. Udokotela ohlinzayo angabuka izithombe ngemizuzwana noma imizuzu yokuskena kwe-iMRI. Lokhu kusho ukuthi izinqumo zingenziwa ngokushesha futhi ukuhlinzwa kungaqhubeka ngaphandle kokulibala. Lokhu kusindisa isikhathi futhi kwandisa impumelelo yokuhlinzwa.

Ekugcineni, khumbula lokhu.

Kulungile, ngakho-ke ngithemba ukuthi usunombono omuhle nge-iMRI, emele i-Intraoperative Magnetic Resonance Imaging , esikhulume ngayo namuhla.

Kalula nje, i-iMRI iyindlela ekhethekile yokuskena esiza odokotela abahlinzayo ukuthi babone ngokucacile ukuthi yini engaphakathi emzimbeni ngesikhathi sokuhlinzwa.

Lokhu kubaluleke kakhulu ekuhlinzweni okuyinkimbinkimbi njengokususwa kwesimila sobuchopho. Kungasiza ukuqinisekisa ukuthi isimila sisusiwe ngokuphelele, okungasiza ekugwemeni isidingo sokuhlinzwa okwesibili. Ithimba lakho lezokwelapha lizothatha zonke izinyathelo zokuphepha ukuze le scan iphephe kuwe. Kodwa-ke, khumbula ukuthi uma unezinto zensimbi emzimbeni wakho (njenge-pacemaker), tshela udokotela wakho ngazo ngaphambi kokuhlinzwa . Uma unemibuzo mayelana nokuhlinzwa kwakho, khuluma nodokotela wakho ohlinzayo okungenani usuku ngaphambi kokuhlinzwa ukuqinisekisa ukuthi konke kuhamba kahle.

Ungakhathazeki, njengoba isayensi yezokwelapha ithuthuka, ubuchwepheshe obusha obufana nabu buza ukukunikeza ukwelashwa okungcono kakhulu.
