I-Magnetic Resonance Imaging (MRI) yitekhnoloji ye-imaging engeyiyo invasive evelisa imifanekiso emithathu eneenkcukacha ze-anatomical. Ihlala isetyenziselwa ukufumanisa isifo, ukuxilongwa, kunye nokujonga unyango.

Izikena ze-MRI zifaneleke ngakumbi ukuba nomfanekiso wamalungu angengomathambo okanye izicubu ezithambileyo zomzimba. Bahluke kwi-computed tomography (CT), kuba abayisebenzisi i-ionizing radiation eyingozi ye-x-reyi. Ingqondo, intambo yomgogodla kunye nemithambo-luvo, kunye nezihlunu, iigaments, kunye nee-tendon zibonwa ngokucacileyo ngakumbi nge-MRI kune-x-rays kunye ne-CT eqhelekileyo; ngenxa yesi sizathu i-MRI isoloko isetyenziselwa umfanekiso wedolo kunye nokulimala kwamagxa.

Engqondweni, i-MRI inokwahlula phakathi kwento emhlophe kunye nengwevu kwaye ingasetyenziselwa ukuxilonga i-aneurysms kunye namathumba. Ngenxa yokuba i-MRI ingasebenzisi ii-x-reyi okanye enye imitha yemitha, yindlela yokucinga ekhethwayo xa ukucinga rhoqo kuyadingeka ukuze kuhlolwe ukuxilongwa okanye unyango, ngakumbi engqondweni.

Ii-MRIs zisebenzisa iimagnethi ezinamandla ezivelisa indawo eyomeleleyo yamagnetic enyanzela iiprotons emzimbeni ukuba zihambelane naloo ntsimi. I-Magnet iyona nxalenye ephambili yenkqubo ye-MRI, kwaye amandla ayo amagnetic field, ukuzinza, kunye nokufana kunempembelelo enkulu kwimifanekiso ye-MRI.

Imagnethi esisigxina eveliswe yi-CSJ, enokuthi isetyenziselwe ukuhlolwa komzimba wonke, yamkele izixhobo zemagnethi ezisebenza ngokuphezulu ezinqabileyo zomhlaba, uyilo loxinzelelo lwangoku lwe-eddy, ikhulisa ubume bemagnethi, ithatha indawo encinci, iindleko zokufakela eziphantsi, kwaye inenqanaba eliphezulu. yokuvuleleka, ukugcinwa kwenkqubo ephantsi kunye neendleko zokusebenza.
