MRI ne ukuchasanisa: ncomo, ukulungiswa. Njani MRI nobuchopho umahluko?

MRI ayikho uviwo yeli lizwe, kodwa ke ngamanye amaxesha ufuna ukusebenzisa izinto nshita ukuphucula indlela ecace ngayo imifanekiso. Olu ugqirha wesifundo umisele kuphela kwiimeko apho indlela esezantsi Akwanelanga ukuba uvavanyo injongo isimo umzimba. Ukusetyenziswa izixhobo diagnostic mihla ngokukhuselekileyo kwaye ivumela imbono olungcono iinkcukacha zincinane. Ngamanye amaxesha kufuneka wenze i-MRI kunye koko, ukuze siqiniseke ukuba afunyaniswe isifo kwaye afumane unyango ngexesha ukuqala.

ulwazi jikelele le nkqubo

MRI (intlokoma magnetic umfanekiso) - uhlobo namhlanje sifo, sivumele ukufumana ezikumgangatho ophezulu imifanekiso amacandelo umgodlo imisipha, amalungu kunye namalaphu elithambileyo amalungu ezahlukeneyo. Ulwandiso Contrast zophononongo ubuchopho kusenokufuneka ukucacisa diagnosis ezithandabuzekayo okanye ubhaqo yamathumba kubungakanani sincinane. Inkqubo le yalula kwaye ulwazi kakhulu. MRI yobuchopho kunye contrast ikuvumela ukuba ngokukhawuleza ngokuchanileyo ukuhlola isixa utshintsho zophendlo lwezifo umzimba yomenzakalo kunye nezifo ezininzi.

Devices for uphando zinokwahluka amandla ayo (ukuba ngee Tesla). Xa ekuxilongweni izifo zobuchopho ukuze imifanekiso umgangatho kuyanqweneleka ukuba iqalise le nkqubo kunye index tomograph 1-1.5 Tesla. Izigqibo Higher sebenzisa akwenzi ngqiqo, kuba eli gunya kwanele, kunye nezixhobo kangako awukwazi ukunika imifanekiso eneenkcukacha kakhulu.

Ezibonisa zokufunda

Ngokungafaniyo MRI eqhelekileyo, isifundo ngokusebenzisa umahluko medium lwenziwa kuphela kwi ubungqina kugqirha, ngokuqhelekileyo kumaziko ezempilo musani ukwenza nto ngaphandle ulwalathiso oluvela itywina. Oku kungenxa yokuba isigulane ziya kuqhutywa izinto ezikhethekileyo ekukhuthazeni isiphumo magnetization izicwili. Le nkqubo lwenziwa kuphela phantsi kweliso anesthesiologist, njengoko awasabela ngayo umahluko kunokuba ezahlukeneyo.

Ubungqina obubonakalayo buxela ukuba MRI yobuchopho kunye umehluko medium:

• eko adenoma yebhinqa;
• kwafunyaniswa phambi kokuba ithumba kwezinye iinxalenye ingqondo (ukucacisa yimvelo yabo);
• multiple;
• iimeko kakhulu of ngesibetho;
• Izifo ezosulelayo e-nervous system kunye neempawu kakhulu zophendlo lwezifo;
• Ubhaqo ebulalayo ithumba Ukudlulela;
• iziphumo ezixubeneyo izifundo eziqhelekileyo ngaphandle okhulisa.

Kutheni ukusebenzisa umehluko medium?

Kwezinye iimeko ufuna imbono ecacileyo ebuchotsheni. Ngokuqhelekileyo, MRI umahluko eyabelwe kukrokrelwa ingozi (okanye ingozi), ithumba ebuchotsheni, kwakunye esekwe Enyanisweni ubukho balo ukufumanisa ubukhulu, isakhiwo imida.

Le isigulane lesitofu iziyobisi emzimbeni ngokusekelwe iityuwa gadolinium. Le metal eqokelela kwiindawo kunye kwanda kokuqukuqela kwamanzi (idla uphawu ngenxa yamathumba ngenxa yokuba ukukhula kwabo ngokukhawuleza). Le mimandla ngokucacileyo ebonakalayo imifanekiso, ngoko phantse akunakwenzeka ukuba kuphoswa. Amalungiselelo ngokusekelwe zinetyhefu esezantsi weli kwaye kunqabile kunokubangela iziphumo ezingalindelekanga.

uphando abaninzi ezinkulu zonyango banokubenzakalisa impilo yomntu, ukuba akunjalo ilungisiwe ngokufanelekileyo ukwenzela le nkqubo. Omnye wabo - i-MRI kunye umahluko. Ukulungiswa umguli kunye emfutshane eneenkcukacha malunga nezenzo zakhe phambi kokuba inkqubo kwaye ngethuba loviwo ukuthintela oku.

Indlela ukulungiselela i-MRI?

Phambi MRI umahluko isigulane kufuneka uyeke ukutya namanzi ngexesha iiyure ezi-2 phambi kokuba le nkqubo. Oku kungenxa ekuqalisweni ichiza emzimbeni (xa kufunyaniswa isifo eqhelekileyo udle usele nawe). Phambi kwesi sifundo, umntu kufuneka asuse zonke iimveliso zesinyithi (nemisesane yokutywina, namajikazi, amakhonkco impahla). Ukuze le nkqubo isigulane idla anikwe impahla enkulu ezilahlwayo, eliquka isixhobo uphazamisana ngexesha scanning. Kwelo gumbi apho vuavanyisi akanako ukuzisa cell phones kunye nezinye elektroniki, amakhadi intlawulo, amaqhosha, njalo njalo. D.

Enye ingongoma ebalulekileyo - amalungiselelo ngokwengqondo iinkqubo yoxilongo. Njengoko isifundo kufuneka ukuba imizuzu engama-20-30 isithuba phantse lavalwa, hayi uhambisa okanye ukuthetha, ukuqesha sengqondo esifanelekileyo. Xa MRI ingqondo kunye uthelekiso kunye nesandi umatshini yenza isandi eyahlukileyo. Ngoko ke, ukuba ukukhusela ezindlebeni umntu ubeka phezu headset okhethekileyo.

MRI ne ukuchasanisa: ukwenza njani le nkqubo?

Ekuqaleni, isigulana yenziwa eqhelekileyo ngemagnethi livakale umfanekiso ngaphandle arhente umahluko. Kuyimfuneko ukuqhubeka ukuthelekisa iziphumo kwaye neziphumo umfanekiso opheleleyo ngakumbi clinical. Emva koko, isigulana ishiya isixhobo, yaye owayelawula bazamile ugqirha efakwa amachiza ungabutofela ukuba isixhasi umahluko.

Ngaphandle kokuba iyeza mihla efana ayiqulathanga iodine cishe non-ezingenabungozi, umntu kufuneka siliphulaphule mizwa emzimbeni wakho emva nolawulo. Ukuba konke kuhambe kakuhle (akukho nesiyezi, isicaphucaphu, iintlungu esiswini kunye nentloko, komzimba), isigulane iyipasise kwakhona MRI. Ngexesha uphononongo catheter efakwa ngcembe wondla ithamo entsha medicament ngaxeshanye kunye nenkqubo isixhobosovavanyo lwemifanekiso.

Ngaba ubuhlungu MRI okanye ukungaphatheki?

MRI akubangi nobuhlungu umntu okanye ezinye iziphumo ntofontofo ngethuba lophando. Umzimba ngamanye amaxesha va imfudumalo kancinane okanye esibuhlungu, nangona abantu abaninzi emzimbeni Andiziva nto. Intshayelelo koko, kwiimeko ezininzi ukunyamezeleka kakuhle. Noko ke, maxa wambi kukho iimeko hypersensitivity ngamnye okanye engavumelani.

Kuyaphela ephambili enxulumene ne-MRI - oku ke ntshikilelo ngokwasengqondweni kwezinye abantu ngenxa kwisithuba ezingaphakathi. Xa izixhobo umoya ngokwaneleyo, kunye noyilo lwenziwe ngohlobo lokuba inxalenye ibekwe ngaphandle emzimbeni wakhe. Ukuze yehla, kufuneka siqonde isigulane ukuba ngethuba lophando ukuba wayebukele ngugqirha, yonke le nkqubo ngokupheleleyo phantsi kolawulo. Kuzo zonke izigulane ngesandla wabeka ibhalbhu okhethekileyo, iingcingo kunye sensor odiyo, nto leyo ke zixinaniswe olwandle kakhulu. Oku kuya kunika uphawu kugqirha ukuba kufuneka uyeke inkqubo kwaye ukunika ixesha umguli ndizole.

Izimo

Izimo for MRI kunye koko ungumzalwana kunye elipheleleyo. Isigqibo sokugqibela malunga ithuba unyango uwave ugqirha. Study ne nshita medium iyapheliswa ngokupheleleyo phantsi kwezi meko:

• ube pacemaker;
• ingenisa kwi umzimba eziqalelo netyhidiweyo magnetized;
• lomonakalo sezintso yayinzima;
• Ukukhulelwa ne zisanyisa;
• kutshanje wenza esinye isibindi;
• aleji iinxalenye yomenzeli umahluko.

Kuba Izimo isihlobo ziquka bephelelwa nezinobunzima ngaphezu kwama-120 kg (ngeeyunithi ezininzi lo mda ubuninzi ubunzima avumelekile). Ukuba umzimba lo yomguli uba wamvambo, kuyimfuneko ukuhlola kunye inkosi, ubulala, ukuba iintsimbi ziyinxalenye idayi eyayisetyenziswa ngexesha le nkqubo.

MRI ne umehluko: baqinisekiswa

Izimvo zabantu MRI ikakhulu cala okanye positive. iimvakalelo ezizodwa uninzi lwezigulane ngethuba loviwo na uvavanyo. Ngamanye amaxesha abantu bakufumanisa kunzima ukuba ndilale phantse cwaka kangangesiqingatha seyure kwindawo esekhusini. Phantse zonke izigulane ingxelo impumelelo aphezulu MRI yobuchopho kunye Ngokwahlukileyo koko, kuba kagqirha ichaza ngokupheleleyo zonke izakhiwo eziyimfuneko. Moshilongo kwi neurosurgery yindlela abaphambili, nayo ixesha yalula ekhawulezayo.

Xa nokubuyekezwa ezigulane abo umahluko uyalisa okanye akaxoleli inqabile kakhulu. Iziphumo ezingentle iziyobisi maxa wambi iboniswa kuphela ukuba nesiyezi kancinane, bekuza ngokukhawuleza. Ngenxa MRI kunye Ngokungafaniyo kubantu abaninzi abagulayo wayenokufunda yamathumba kwi zigaba yokuqala, ukuvumela ixesha ukususa okanye uqale unyango endala.
