MRI - lokhu ... Magnetic resonance imaging: kuphi, ukuthi kubiza malini

Magnetic resonance imaging (MRI) - isifundo indlela non-koda yesimanje zokuxilonga, okuyinto ikuvumela ukuba zibukeke ukuhlola izicubu olujulile begazi. Kusekelwe mkhuba ngokomzimba ezifana zenuzi resonance kazibuthe. Lokhu kungenziwa kuqondwe kusuka egameni le ndlela. Lapho uyisebenzisa, nesilinganiso wenziwa ukuthi ukusabela kunjani kagesi we nuclei athomu. kuvame kakhulu ukuba kusetshenziswe ama-athomu ye-hydrogen.

MRI - Yini leyo?

kwezicubu Human igcwele hydrogen. Lokhu kukuvumela ukuba sihlole kwezitho nezicubu zomzimba, ikakhulukazi besebenzisa amagagasi kazibuthe kwalesi sakhi zamakhemikhali.

Proton (kuyizinhlayiyana kahle icala) a athomu ye-hydrogen has a spin (okwamanje la mandla kazibuthe), okuyinto akwazi ukushintsha isikhundla salo isikhala lapho ngaphansi namandla amakhulu kazibuthe. Ngo inkambu zangaphandle kazibuthe, kuyoba spin ohlangothini olulodwa noma sihlose okuphambene mayelana kulo mkhakha. Lena ngesisekelo MRI ukuhlola.

Endaweni uphenyo wadalula emisebeni kagesi imvamisa ezithile. Nokho, abanye proton ukushintsha isikhashana yabo kazibuthe siyachithwa, bese ubuyela ukuqala isikhundla. Ekupheleni ukuchayeka emisebeni kagesi, icala izinhlayiya hydrogen ukukhishwa amandla aziphumulele. Lokhu amandla itholwa nge imishini ekhethekile (tomograph) ngesikhathi le nqubo.

Kuyini ukusetshenziswa?

MRI - cwaningo, okuyinto ikuvumela ukuba uthole swe kahle yonke soft izitho zangaphakathi nezicubu (ubuchopho, umgogodla, uqwanga, njll ...). Le ndlela ivumela cwaningo ukuhlonza ngisho nezinguquko ezincane kunazo nezinqubo ukuvuvukala, ukunquma ukuthi lingakanani ijubane lokuya khona ukutshezi yemvelo (igazi, izindlala zamanzi, cerebrospinal fluid), ukubona ukusabela cortex cerebral ukushintsha umsebenzi uhlaka. Kwezicubu nge okuqukethwe amanzi ongaphakeme (amaphaphu namathambo) zihlolwa nge tomography, t. K. isithombe wabo eliphansi. Ikakhulukazi kabanzi ekutadisheni neurosurgery kanye Neurology. Kule ndlela, kungenzeka kube nabathile Izimo.

Izimo

MRI has Izimo yayo. Zingaba ngokuphelele futhi isihlobo. Izimo Ingabe Ohulumeni Banalo Lonke ukuphakamisa ukuthi lolu cwaningo ayikwazi ukudlalwa ngaphansi kwanoma yiziphi izimo. Lapho isihlobo contraindication MRI ungalilahli iyathandeka, kodwa ngampela ke kuvunyelwe.

Izimo eliphelele

• Elingenalo iwashi lenhliziyo.
• Metal izimila.
• amadivaysi Ilizarov nge isakhiwo sensimbi.
• Ephakathi indlebe izimila equkethe metal magnetizable noma zikagesi.

Izimo isihlobo

• Insulin amaphampu.
• Evuselela isimiso sezinzwa.
• valve inhliziyo Artificial.
• Izimila of endlebeni-non-ferromagnetic.
• Hemostats.
• Non-ferromagnetic Ukugunda semithambo (Ukugunda) e aneurysms intracranial.
• Inhliziyo ukwehluleka phakathi decompensation.
• Claustrophobia (netwetwe ukwesaba endaweni evalelekile).
• Isifo sengqondo kanye isimo ukungadli isiguli.
• Utshwala ukudakwa.
• yisimo esibi kakhulu isiguli.
• Senyanga yokuqala sokukhulelwa.
• Tattoos ukuthi zenziwa nge udayi kokuba izingxenye zensimbi.

Titanium lokufakelwa kwezitho ungeyena contraindication isifundo, isb. A. Ziyakwazi non-ferromagnetic. Ngaphezu kwalokho, kukhona imikhawulo isisindo ukudlula i-MRI. isisindo isiguli akufanele bube ngaphezu kuka-120 kg.

Ukuba intrauterine kudivayisi, ibele esikhathini kungukuthi contraindicated i-MRI. Isinqumo sokugcina ukwenqaba le nqubo ithatha radiologist MRI.

Kanjani ukufeza ucwaningo?

Kanjani ukwenza i-MRI? Le nqubo Akudingi ukuqeqeshwa okukhethekile. Ukukhethwa iyona MRI kwezitho okhalo. Ngobusuku obandulela inqubo kungathatha ukudla, kodwa ngokulinganisela. Iziguli ucelwa ukususa zonke izesekeli (amawashi, izinwele omfisha, imigexo), kanye amazinyo okufakelwa, izinsiza kokuzwa futhi iwigi, uma izinto ezinjalo kukhona. Ngaphezu kwalokho, ama-credit card namakhadi asebhange futhi, kumele kwesokunxele ngaphandle kwehhovisi, okungukuthi. Ukuze. Zingase ukuwohloka. Zonke metal nensimbi, kanye izinto ngogesi kumele kwesokunxele emnyango, t. Ukuze. Zingaphazamisa kazibuthe, okuyinto ekhiqizwa ngesikhathi sale nqubo. Lokhu kuzonciphisa izinga isithombe. Ngaphezu kwalokho, lokhu kazibuthe kungalimaza electronics.

Uma isiguli unazo lokufakelwa kwezitho metal, yokufakelwa inhliziyo valve, amadivayisi otshaliwe electronic nokunye. E., Kuyadingeka ukwazisa udokotela ngakho. Ukuxilongwa MRI kwezinye izimo kungase contraindicated (njengoba kushiwo ngenhla) ngenxa kungenzeka umonakalo empilweni isiguli, kanye nomthelela umphumela inhlolovo. Uma udokotela unqume ukuthi azikho Izimo, isiguli uzobe mubamema ehovisi inhlolovo. Eminye imitholampilo ukunikela ukushintsha ibe ijazana lasebusuku, kodwa ungakwazi bahlale izingubo zabo, uma awunazo izinto ferromagnetic.

Ngakho, indlela yokwenza i-MRI? Ukuze enze lokhu inqubo, isiguli itholakala Umhubhe MRI Enani. Phakathi nesifundo, kubalulekile ukuba balondoloze baxhashazwe ngokuphelele. Kuleli kuncike izinga izithombe. Izibani Umhubhe futhi fan iyasebenza, ukuze wenze kube lula ukushaya futhi sakwazi ukuphefumula. Futhi kukhona i-microphone eyakhelwe ngaphakathi. Uma kudingekile, ungakwazi ukukhuluma nodokotela ngubani cwaningo.

Okunye ukuhlola okwenziwa ne-ejenti ukuze kuvele umehluko. Uma kudingeka, i-contrast is injected umthambo ingalo indololwane.

isikhathi esingakanani kanti inqubo?

Lolu hlobo cwaningo Uthatha imizuzu engu-15 kuya ku-45. Ngemva kokuphela inqubo isiguli ungacela ukulibala kuze kube ngomzuzu lapho isibhamu sakhe kungukuthi bakuzwisise ngokuzeleko ukungathathi ochwepheshe futhi ngeke ivele eqiniseka ukuthi abathola isahlulelo kahle, t. E. Ngini bengayi.

izingane ezincane MRI

MRI ngokuvamile elibekelwe izingane, uma udokotela esolwa zokugula lapho awokuthi umonakalo izakhiwo ingqondo. Surveys ezinye izitho zangaphakathi usebenzisa le ndlela izingane enqunyiwe ngaphansi ngokuvamile.

Le nqubo Kunconywa emva izingane engamashumi 5 ubudala. Kubalulekile kakhulu ingane phakathi nesifundo walala izimele. Kuthatha imizuzu engu-15 kuya kwengu-40. Ngokusobala, lokhu isikhathi ngaphandle ukunyakaza athwale nesineke kancane nzima kakhulu. Uma ingane iziphatha restlessly besafunda, izithombe kuyoba eliphansi futhi ningathwali yiluphi ulwazi ukuze udokotela.

Umama avunyelwe ukuba ehhovisi ngesikhathi luhlolo kwengane yakhe. umbhobho kanye nethuba ukukhuluma ingane ngesikhathi sale nqubo okuhlanganiswe e isithwebuli iyunithi.

In an icala ngokwedlulele, uma ngaphandle kulolu cwaningo Awukwazi ukwenza, ungenza i-MRI ezinganeni futhi isencane. Kodwa kulokhu ukubulawa kwezinzwa avunyelwe kubathene ingane.

inqubomgomo MRT khulula OMC

Esinye nesinye isakhamuzi we Russian Federation has umshwalense wezokwelapha. Ngingakwazi ukwenza i-MRI ngaphansi kwenqubomgomo OMS khulula? Impendulo ingu-yebo - kodwa hhayi ngaso sonke isikhathi. I umshuwalense wezempilo ngempela afakwe ohlwini amasevisi khulula. Uma i-MRI ukuhlola ekuklanyweni inqubomgomo iye kulolu hla, e umphakathi sokunakekela impilo, lapho kukhona Enani, ungakwazi kalula uhambe ngenqubo mahhala. Kodwa kubo bonke cwaningo kwenziwa mahhala akunakwenzeka. Ngemva i-MRI - zobuchwepheshe nocwaningo ezibizayo. Nokho, ngo-izikhungo zezempilo zomphakathi, abelwe quota mahhala ukudlula i-MRI. Kodwa zimbalwa - ukwelashwa ambalwa nje ngenyanga. Uma kudingeka, lokhu quota ingatholakala. Ukuze udlulisele lesi nenqubo ethile yokuthola isifo khulula isiguli kufanele aphathe i yokudluliselwa unolwazi kudokotela. With isiqondiso esinjalo isiguli Ungabeka endaweni kulolu hlobo ukuxilongwa, noma uma ungaya ngokusebenzisa inqubo kwenkokhiso nganoma yisiphi isikhathi esikahle ukuze isiguli. Udokotela itsini, lapho kungenzeka ibhekane i-MRI mahhala. Uma odokotela ngeke likwazi ukunikeza ulwazi ezifana, ungaxhumana ngqo nenkampani yakho yomshuwalense.

MRI: izindleko

Shaja ibhekane inqubo MRI kungaba kokubili ezibhedlela zikahulumeni nasemitholampilo yakule kwezohwebo. Njengoba wazi, amasevisi MRI akuzona ezishibhile. Izindleko incike ngohlobo lomshini isetshenziselwe ucwaningo, isithunzi emtholampilo ibanga lalo ukusuka enkabeni yedolobha. Futhi kuwufanele ezimbalwa eshibhile ebusuku-time-MRI. Ngokuvamile le nqubo ohlelweni umtholampilo izaphulelo, kodwa kuyadingeka ukwazi kusengaphambili. Ngokwesibonelo, isaphulelo ku MRI at 5% bengathola izigaba ezilandelayo izakhamuzi:

• Umhlalaphansi.
• Amalungu kanye nezingqalabutho ezimpi.
• Bendawo yengozi eChernobyl.
• iqembu ngokwenyama abagula lokuqala nelesibili.

A Isaphulelo of 10% bangalindela ukuba:

• Ukuvinjelwa.
• Abahlanganyeli ngokuthi yiMpi Enkulu Yobuzwe.
• Abasebenzi bezempilo ku isethulo se-diploma kwemfundo izitifiketi umsebenzi wezokwelapha ukuthi njengamanje, isakhamuzi ukusebenza okukhethekile yabo.

Intengo futhi kuncike ukusetshenziswa Ngokuphambene ejenti ngesikhathi inqubo-MRI. Izindleko isifundo Ngokuphambene kuyoba ephakeme kunaleyo ngaphandle kwalo. Ukunemba uphethwe usebenzisa yalolu ketshezi inyuka kakhulu.

Izindleko incike endaweni inhlolovo. Intengo isilinganiso ukuhlolwa elilodwa zone ngaphandle umehluko kusuka 3500 kuya ruble 8000.

Can MRI umonakalo empilweni?

Isihloko zonke izidingo ezidingekayo (ukususa zonke metal nezinto electronic), lolu hlobo cwaningo ayikwazi ubuhlungu nganoma iyiphi indlela. Okungenani, kuze kube manje akukho Ezimweni ezinjalo eqoshiwe. X-ray azisetshenziswa, ukuze ukwazi ukufeza inqubo futhi njengoba kaningi njengoba kudingeka.

Uma kukhona nesineke yokukhulelwa amasonto 12, odokotela basikisela ukuthi kunobungozi encane ezingenzeka embungwini, kodwa lokhu nokucabanga kwenzelwe nje theory. Iziguli claustrophobia, ngaphambi inqubo kufanele ke ukuvimbela onguchwepheshe ngubani uzolifeza cwaningo. Kulokhu, inqubo ovunyelwe umeme omunye eziseduze.
