MRI wentliziyo

Magnetic intlokoma umfanekiso - yenye yeendlela ezininzi efundisayo kuxilongo mihla. Le ndlela yenza kube lula ukufumana umfanekiselo imizimba ezahlukeneyo ngexesha sesindululo yendalo yaye baphumle. Ukongeza, scan MRI kwenziwa uqikelelo 2-3 eliphezulu resolution, it ikuvumela ukuba ukuhlola iimpawu olusebenzayo omzimba.

MRI in zentliziyo kunye kwentliziyo uqhaqho yi ubuchule iluncedo kakhulu. Ngoncedo ukufunda intliziyo, ukusebenza okufanelekileyo kwezivalo, utshintsho kuwo onke amagumbi ngentliziyo ngexesha isiphakamiso yindibanisela kwegazi kwimikhumbi ezinkulu (pulmonary, aorta). Alithandabuzeki elokuba, imifanekiso MRI ezibalulekileyo ekufundeni isifo sentliziyo, iposi engabalulekanga kunye nesifo sentliziyo kobuchopho.

kanjani i MRI zentliziyo?

Ngexesha inkqubo, a elektrovolnami nomonde obeka yangaphandle zibuthe. iiseli okufakwe ukufunxa amandla radiation electromagnetic. Ubungakanani ukufakwa kuthiwa livakale, kwaye kusenokwenzeka ukuba umlinganiselo. Emva kokuba zokukhanya luyekisiwe, iiseli zanikwa amandla ezifunyenweyo, kwaye ezinzileyo kunye nemishini ekhethekile. Ukuhlalutya amanani wabuya waza wafumana amandla, inkqubo yekhompyutha uyila imifanekiso izicwili baboniswa kwimitha.

Record MRI eyenziwa ukufota izilayi ngokwemaleko. Ngoko ke ugqirha, xa ngokuhlalutya iziphumo nako ukubona utshintsho enzulwini ijwabu kwentliziyo.

Wentliziyo MRI lwenziwa njengoko kunye nokusetyenziswa arhente koko, okanye ngaphandle, ngokuxhomekeke iinjongo kunye kwimeko ethile. agents Contrast zisetyenziswa ukuxilonga iqhosha elandulela eli, post-iposi, ischemia engabalulekanga, kunye notshintsho arhabaxa.

Kwiimeko ezininzi, i-arhente umahluko gadolinium - amalungiselelo gadopentetat dimeglumine (gadopentetate dimeglumine).

iziphumo MRI e zentliziyo sikwazi ukubona ukuba Amaqhinga yokusebenza emva wahlaselwa yintliziyo ngobuciko eliphezulu. Ngokuhlalutya utshintsho ancedisana zentliziyo, kuyenzeka ukuba ngokuchanileyo ukucwangcisa yayivele ngenxa igazi nokuqhwalela (ischemia) utshintsho eludongeni ventricular. Ischemia Uxhokonxwa okungaqhelekanga batsho. MRI ivumela ukufunda ubungakanani ezi nguqu iinkcukacha aze athathe isigqibo sokuba coronary kwimithambo esa yokumilisela. Ukuba kwimimandla engabalulekanga accumulated izixa olongeziweyo gadolinium, kubonisa utshintsho necrotic ayibuyiseki umva kwi kwezihlunu entliziyweni. CABG uqhaqho unako ukubuyisela ukuhamba kwegazi, ngokudlulisela iindawo ezivaliweyo ukuhamba kwegazi. Kodwa ukuba ukucwangcisa necrosis, utyando ayiyi kunika oko akufunayo, aveze umthwalo ongeyomfuneko emzimbeni. Noko ke, xa kungekho necrosis, CABG ukusindisa intliziyo yesigulane. Ngenxa yesi sizathu, igazi MRI ludlala indima ebalulekileyo ekujonganeni iingxaki inhliziyo.

Xa kuthelekiswa ne-echocardiography okanye MRI, i ukukhutshwa Itomography, kunokwenzeka ukuba ukuthetha elandelayo strong icala magnetic livakale umfanekiso: ekufumbekeni gadolinium kwenza kube lula ukufumanisa ngokuchanileyo eliphezulu ziqwempu non-akhulayo kwaye myocardium namahlelo ibekwe ngaphakathi inwebu yesihlunu eludongeni kwentliziyo.

MRI wentliziyo: ekuqhubeni iinkqubo

Umda izixhobo MRI yomguli ubuxoki cwaka umfanekiso eshukumayo kwehlisa esemgangathweni. Kuba ixesha eliqhubekekayo le nkqubo ingathatha naphi na ukusuka kwimizuzu engama-30 ukuya kwengama-90. Office ivavanywa apho, ngofinyafuthi kakuhle yaye umoya. Xa uphando abasebenzi bezempilo kufuneka ukuba kuqinisekiswe imo obutofotofo isigulane.

Contraindication nokuziphatha MRI kujongwe yi nesincedisi-ntliziyo, implants zesinyithi, kunye nezinye izinto ezifanayo.

Zonke ezinye Akukho mfuneko uqeqesho olulodwa ukwenza MRI intliziyo.
