Olunye uhlobo oluqhelekileyo lokuvavanywa okungabonakaliyo
I-MRI, eyaziwa nangokuthi i-imagination magontic resonance, i-test free-invasive test test (in-invessable test test) esetyenziselwa ukuqhubela phambili imifanekiso emibini yeempawu zomzimba. Inkqubo isebenzisa imimandla emikhulu yamandla ukwenza imifanekiso yangaphakathi yomzimba.
I-MRIs isetyenziselwa ukufumana iingxaki ngaphakathi komzimba okanye ingqondo ngaphandle kokuhlinzwa, kwaye iyakwazi ukubona ukungaqhelekanga ngaphandle komzimba.
Ngubani ongenako ukufumana i-MRI
Izigulane ezifakelwe emzimbeni wazo ezinezitye, ezifana ne-pacemaker okanye ezinye iindidi zezixhobo zamathambo, zingenako ukufumana i-MRI njengoko umatshini usebenzisa ama-magnet anamandla kakhulu ukufumana imifanekiso efunekayo. Lo mqathango ungasetyenziselwa ezinye izinto zetsimbi emzimbeni, njengenqabana, i-shards zensimbi kunye nezicatshulwa ezifanayo. Oku kungenxa yokuba umatshini usebenzisa amatshini amakhulu kakhulu ukuvelisa imifanekiso esetyenziselwa ukuxilonga ukugula kunye neemakethi zinokutsala isitye esisemzimbeni.
Ukuba kukho nawuphi na umbuzo ukuba isiguli sinokuthi sineentlobo zetsimbi emzimbeni wazo onokuphazamisa ukuhlolwa kwe-MRI isigulane sinokuba ne-X-ray, ebonisa ngokucacileyo isinyithi, okanye ingaba ne-CT scan engasebenzisi izibane ukuvelisa imifanekiso yangaphakathi yomzimba. Oku akunjalo ngenxa yokuba ezininzi izigulana ziyazi ukuba zinaluphi na uhlobo lokufakelwa; Nangona kunjalo, ukuba isigulane asikwazi okanye singakwazi ukubonelela ngembali yonyango ingozi yokwenza lolu hlobo lokuskena iphezulu.
Abantu abane-titanium emzimbeni wabo baqhelekile ukuba babe ne-MRI.
Iinzuzo zeMRI
Uvavanyo lwe-MRI luvumela iqela lokunakekelwa kwezempilo ukuba libone izakhiwo zangaphakathi zomzimba ngaphandle kokwenza isicatshulwa. Uvavanyo lukhawuleza kwaye luyakwazi ukuvelisa imifanekiso echanekileyo. Umzekelo, ukuba isigulane sinezibonakaliso ezinjenge-stroke, i-MRI inokwenziwa ukujonga imida yegazi yengqondo - nokuba imitya encinci enokuba nzima ukuyihlola.
Imifanekiso eneenkcukacha eziveliswe yi-MRI ingaba luncedo ekuhloleni isigulo esinokuchaphazela amathambo, imisipha okanye ezinye iintlobo zeethambo. Ukuba ugqirha wakho ugxeka ukuba unesifo okanye inkqubo yesifo, i-MRI ingayalalwa ngenzame yokuchonga ingxaki. Kwezinye iimeko, ukuxilongwa kungenziwa nge-MRI kwaye kunokuthintela okanye kubonise isidingo sokuhlinzwa .
Ngaphandle kokungathandeki kokuhlala kusekwimeko enye ngelixa uvavanyo lugqityiwe, i-MRI ayibuhlungu. Umatshini unokuba lukhulu xa usebenza, kodwa i-earplugs ihlala ikhona kulabo abaxhatshazwa yingxolo.
Akukho mijelo eveliswa ngumshini we-MRI, ngoko ingozi yokuba ne-MRI ayifanelekanga isigulane esingenaso isinyithi emzimbeni wazo.
Vula iMRI kunye neMRI yeNdabuko
Kwi-MRI yendabuko, isigulane sifakwa ebhedini ehamba ngaphakathi kwiphubhu, apho i-MRI yenziwe khona. I-MRI evulekile, inketho kwizigulane ezithinteka zizikhala ezincinci okanye zikhulu kakhulu, ayifuni ukuba izigulane zifakwe kwi-tube, kodwa zenziwa "evulekile".
Izigulane ezidinga i-MRI kodwa zineengxaki ngeendawo ezincinci zihlala zinikwe iyeza ukuze zinciphise izinga lokuxhalabisa phambi kwenkqubo.
Iintlobo zeMRI
I-MRI iyalulwa kunye okanye ngaphandle kokungafani. Uhlobo lokuphambana nolwelo olunikezwa nge-IV, kwaye lunakho ukuvumela imifanekiso eninzi efumanekayo. Kwizigulane ezininzi, i-MRI ngaphandle kokungafani, ilandelwa lijoyi lezinto ezichaseneyo kunye ne-MRI yesibili, oku kwahlukileyo. Kwixesha elidlulileyo, abantu abaneentlanzi ze-shellfish abazange bahluke njengoko bequkethe iodine. Iintlobo ezahlukeneyo zokuchasana kuthetha ukuba i-shellfish isifo sokungabikho nto ayisayikuthintela ukusetyenziswa kohluke.
Zonke iindawo zomzimba zinokukhishwa ngeteknoloji ye-MRI, kuquka intliziyo nengqondo.
Eyaziwayo Njenge: UkuTyekiswa kweMagnetic Resonance , Open MRI
Imizekelo: I-MRI yayinconywe ukuba icinge ukuba isigulane sagubha ngenxa yesifo.
