Ntoni na MRI entloko? Magnetic liyenza umfanekiso

Magnetic intlokoma umfanekiso yenye yeendlela ezininzi ezintsha nezisebenza zokufumanis izifo zengqondo, ingakumbi imvelaphi luvo. indlela MRI ukuba balobe ezinye esicwangciswe ingqondo, kwakunye ekufumanekeni ezingaqhelekanga kubume bayo. Traditional x-reyi ayiniki isaziso esibonisa MRI entloko.

Yintoni na ufakelo

izixhobo lohlobo ngokuba umfanekiso ikhangeleka ngathi ityhubhu zezindlu elikhulu engqongwe umazibuthe wakhe. Isigulane elala phezu kwetafile uyivulele yokufundisisa, ukutyibilika ngaphakathi umazibuthe. Nokwenza iMifanekiso ezithile (uyilo kunye kwitonela elincinane) ziveliswa ngokulandelelana apho umazibuthe iquka itafile nomonde ayikho ngokupheleleyo.

Kukho izixhobo MRI, evulekileyo kwi izabelo ecaleni. Loo nkqubo kuhle lokufundisa abantu sidudla nabo besoyika zizithuba ezivaliweyo. Iseti yangoku imagers livakale magnetic zinika ithuba lokwenza kuqhume enkulu kuphando ezahlukeneyo. Nakuba kunjalo, ukuba ufake indlela elula kusetyenziswa umazibuthe eziphelelwe lixesha, umgangatho ukubonakala ukuze lincitshiswe. Kukho izifundo ukuba iyunithi evulekileyo awukwazi ukwenziwa.

Obubonakala ukwenza Itomography

Ubungqina obubonakalayo buxela ukuba MRI kweenqanawa kwentloko kungaba:

• ikhanda;
• nokulimala engqondweni ebuhlungu;
• badla ngokubonakala nesiyezi;
• nokuxutha izinto ezifana sokuwa;
• neengxaki zempilo olujikeleza;
• ngesibetho;
• turbidity kunye nokulahlekelwa lokuqonda;
• Iimvavanyo engqina ubukho kwingxelo;
• ukwanda okanye ukuncipha uxinzelelo.

Xa mpawu zingasentla kufuneka mhlawumbi ukwenza i MRI. A ithumba ebuchotsheni, ezathi zavela ngenxa yonyango ezilibazisekileyo kugqirha, oku indaba ehlekisayo. Ukuba umfanekiso indawo yokungabikho yeengxaki entloko, ngoko kuyimfuneko ukuba sifune unobangela kwenye indawo.

Ziziphi iinkalo wasebenzisa MRI

Magnetic intlokoma umfanekiso isetyenziselwa ukuqingqwa kwezifo ezithile kunye neemeko ezifana:

• yintloko imvelaphi bangabonwa;
• izifo endlebeni yangaphakathi kunye amehlo;
• ngesibetho;
• ukusilela ukusebenza kunye nesifo cerebrovascular (umz, aneurysms);
• umkhuhlane yebhinqa;
• ukuphatheka;
• izifo ezithile lwenkqubo yemfundo nervous system (multiple);
• ithumba ebuchotsheni.

Indlela ukulungiselela inkqubo

uqeqesho olulodwa iyafuneka kuphela xa kwisisu kunye nokufunda amalungu zangasese. Kwiintsuku ezintathu ngaphambi kokuba saveyi kuya kufuneka ukuba ukuthobela ukutya glycoprivous, nangenxa imini - thatha isidlo ukukhanya, yaye musa ukusela iti olomeleleyo nekofu, ugqirha wakwazi ukufumanisa ukuba MRI ibonisa intloko yesigulane. Isigulane nangoku ukuba iiyure ezi-5 phambi kwesiganeko ukusebenzisa amanzi kunye nokutya.

Ukulungiselela yokuthwebula phantsi Ukubulawa

Kule meko, njengoko kukho imithetho ethile yokulungiselela, oko kukuthi:

• njalo ubonane nogqirha;
• Kwathi iinkcukacha eziyimfuneko;
• akuvumelekanga ukuba bangasezwa ngendebe 1 iiyure ezi-2 phambi kokuba uhlolo;
• Ukudla athathwe kwi 9:00 phambi sifundo;
• Ukuba isigulane unxiba lenses, maze azise oogqirha;
• musa ekucoceni imveliso zolusu, ingakumbi, musa ukusebenzisa izithambiso;
• kusalisa igumbi elandelayo zonke izincedisi metal Detachable (kubandakanywa nezacholo, amazinyo).

Njani yisaveyi

Indlela yokwenza i MRI ubuchopho kwaye wachitha njani? Ngoku ngakumbi ngale kuya kuxoxwa. Ukwenza umfanekiso nga kwenziwe umyalelo esibhedlele kunye nendlela ambulatory. ray Assistant kubeka umguli phezu kwetafile eshukumayo, indawo yomzimba wakhe busisigxina ngokusebenzisa izileyi ezongezelelweyo namabhanti, igalelo kwindawo yayo cwaka. La manani achazwe kwindawo sincinwa iimodyuli emzimbeni zicwangciswe kunye iingcingo ezifumana kwaye uthumele namaza erediyo. Xa ubuchopho MRI Ufakelo zibekwe kufutshane emantla.

Ukuba kukho imfuneko yokuba asebenzise arhente umahluko kwinkqubo wokuvelelwa, ngoko umongikazi uyakwazi ukufaka i catheter kwi Kwangale ingalo. Ukuze ityhubhu bangathungelana enehlala lelabhastile saline komzimba, obubonelela inkqubo wokuhlamba efanayo. Oku kushenxisa odla sokungeniswa kwawo phambi kokuba izinto umahluko. Ekugqityweni yonke nokuqhathwa wokulungiselela le theyibhile isigulane igqithiselwe ngaphakathi umazibuthe, okuyinto ngokwaso umatshini MRI. Iwodi inxenye engephi bezonyango uviwo ngaphandle kwegumbi unyango.

Emva kokuba ekupheleni kwesifundo ugqirha ithumela umguli kwi kwipaseji ukuba silinde iziphumo zokugqitywa imifanekiso, njengoko kunokufuneka uluhlu eyongezelelweyo imifanekiso.

Inkqubo umfanekiso ngokubanzi ibandakanya imveliso iimephu ezilandelelanayo. Ngamnye kubo kuthatha imizuzu embalwa. Kwaye ke isiganeko ngokwayo idla ithatha ethile imizuzu engama-45.

Ukongezelela MRI ingqondo (ukubuyekeza kuyo, ungenza kuphela ukuva okulungileyo) kwenziwa okwangoku, kunye spectroscopy livakale zibuthe, nto leyo evumela ukuvavanya imisebenzi kwemichiza ngaphakathi kwiseli. Loo uhlolo kuthatha banemizuzu engama-15.

Izinto eziluncedo ze MRI

MRI zinezibonelelo ezininzi.

1. Itomography - indlela umfanekiso ayiphazamisi apho sinxulumana nesenzo ionizing radiation.
2. MRI kwenza kube lula ukufumanisa mgaqweni ukuba ezingabonakaliyo ngenxa wethambo kwezinye ubuchule umfanekiso.
3. Magnetic intlokoma imifanekiso yobuchopho kunye nezinye iinxalenye entloko, ubuso eneenkcukacha ngakumbi novakalelo ngaphezu kwezinye iindlela. Lo mba yenza Itomography isixhobo esibalulekileyo luxilongo sokuqala, ozibonayo lwezifo ezahlukeneyo, kunye nangezilonda.
4. I-arhente umahluko ezisetyenziswa kuphando ukwenzela ukubonisa obonisa MRI intloko Uxhokonxwa iziphumo komzimba ngaphantsi kwe umbandela umahluko esekelwe kwi-ayodini zisetyenziselwa eqhelekileyo X-reyi.
5. Magnetic intlokoma umfanekiso uyakwazi ukubona istrowuku kwi lokuqala kakhulu eqongeni, ebonisa intshukumo kwamanzi ancedisana le microparticles. Le ukuhanjiswa kwamanzi, ngokuba kwe-, wabatshabalalisa inkoliso nangemivumbo.
6. MRI kunceda amagqirha esweni imeko noshowo amalungu obuchopho.
7. Enye yezi nguqulelo, eyaziwa ngokuba ngemagnethi livakale angiography (MRA) libonelela nokuthelekelela ngokucokisekileyo imithambo yegazi ebuchotsheni rhoqo ngaphandle arhente umahluko.
8. MRI intloko, ixabiso apho simi ku 3,500 engange. 5000 Hlikihla., Kuba advantageously isixhobo ukuqina ukuba ikhombe ngamathumba ebuchotsheni.

Inokuba yintoni ubungozi

1. Ukuba kusetyenziswa zomzimba, kukho amathuba umthomalalisi ngokugqithiseleyo. Igcisa okanye umongikazi ebukele imisebenzi ebalulekileyo ukwenzela ukunciphisa eli ithuba.
2. inkqubo MRI phantse engenabungozi kumndilili nomonde, ukuba ulandela imithetho yokhuseleko.
3. Kukho ingozi encinane kakhulu yeziphumo ezikumila kunje xa lesitofu izinto umahluko. Ezi zinto zidla kubonakaliswa kancinane kwaye kungekho naziphi na iingxaki bahlolwe ngokusebenzisa iziyobisi. Kwaye ngeli lixa iziphumo ze MRI kobuchopho ebonakalayo.
4. Okwangoku, kukho isiphumo icala umfanekiso luthathwa abanesigulo nephrogenic systemic. Nangona kunjalo, oku kungenzeki rhoqo, yaye le ngxaki yadula ngenxa yolawulo idosi omkhulu arhente uthelekiso kunye nezigulane gadolinium nomsebenzi kidney kakhulu.
5. Ngaphandle kokuba lo mhlaba otsalayo onamandla ingozi, izixhobo zonyango elimiselweyo kuni, ubunjwe metal, angadala umonakalo okanye abangele kabi ngexesha MRI.

Ngubani na ukulandela inkqubo

Magnetic intlokoma umfanekiso akuthethi esingenakubangela naliphi na umonakalo kuloo mntu, ukuba amanyathelo okhuseleko ziyafezekiswa. Izigulane ukuba uqhaqho lwemiphunga yentliziyo okanye izigulane izicwangciso ezithile zonyango kungaba lula ngokusebenzisa inkqubo kwaye ufumanise ukuba yintoni ebonisa MRI lasentloko, kunye namanye amaziko. izixhobo ezikhoyo:

• valve yenhliziyo (ngaphandle - ebuhlanti ibhola okanye metal);
• sutures utyando okanye iiklip;
• izihluzi Vena cava;
• amalungu yokufakelwa;
• shuntovannye zohlobo for hydrocephalus;
• ezityiwa;
• iimpompo balawule ukuxhuma.

Izimo

Kuba iimfuno ezithile, i-MRI owonona kuphela, ukuba ikhona:

• ukuva nokufakelwa;
• pacemaker;
• izinto metal emehlweni;
• ubunzima ezingaphezu kwe-140 kg;
• sifo kakhulu lung (dysplasia bronchopulmonary, tracheomalacia);
• nokukhulelwa;
• isifo reflux Gastroesophageal;
• ufudusiwe iimpompo insulin (unyango diabetes);
• ikliphu kwemithambo yobuchopho (ikliphu sentsimbi kwi isitya igazi intloko);
• bephelelwa umoya;
• wafaka intonga ekomelezeni umnqonqo.

Ukuba umntwana lowo wenziwe MRI kwentloko (ixabiso kweenkqubo ezinjalo ziya kuxhomekeka apho ophethe, kodwa avareji ivela 2500 miri.), Koko kufuneka ubuze kwangaphambili kunye lobuxhakaxhaka umfanekiso. Ngenxa yokuba abantwana kunzima kakhulu ukugcina ngaphandle ihamba ixesha elide. Kule meko, sebenzisa imithi umthomalalisi - belele iipilisi, nadlamkisayo okanye zomzimba. Kwakhona, xa kukho imfuneko, abazali bavumelekile ukuba umntwana MRI isifundo iimviwo.
