I-MRI iyimifanekiso yokumangalisa yamandla entloko, oko kukuhlolwa okungenasiphene okukunceda ukuchonga ngokuchanekileyo ukuxilongwa nokunika unyango olufanelekileyo.
Umgaqo woviwo
Ingundoqo ye-MRI kukusetyenziswa kwamagunya amakhulu aphezulu kunye neepulse ezichanekileyo ezidluliselwa kwikhompyutheni, okubangela umfanekiso ochanekileyo kuzo zonke iingqondo zengqondo:
- izicubu ezithambileyo;
- amathambo amathambo;
- ezinye izakhiwo zomzimba wekhanda ngaphakathi.
Umphumo wohlalutyo olunjalo unokufundiswa kwisebe, kuboniswe kwisikrini esikhulu usebenzisa iphrojekithi, ithunyelwe nge-imeyile kwaye iphrintiwe. Le ndlela ikhuselekile ngokupheleleyo, kuba izinto ezisetyenzisiweyo, umzekelo, xa i-X-ray ingafuneki.
Imifanekiso echaziweyo, okuyizicatshulwa ezikwindawo ezihlukeneyo, vumela oogqirha ukuba babone ngokuchanekileyo kunye nokuchaneka naziphi na iziphene kwizitho ezithile. Iindlela zonyango zanamhlanje zijonga ukuba i-MRI ibe yindlela echanekileyo neyona ndlela ibukhali yokujonga izigulane nokugqiba izifo.
Ziziphi izifo eziza kubonwa nge-MRI?
Xa kukhutshwa ukuthunyelwa kwi-MRI yeenqanawa ze-cerebral, oko kukuthi, ziphi iinqununu okanye iinkcukacha eziboniswayo, ugqirha oya kwixesha ubonisa ukuxilongwa kwangaphambili kunye nawaphi amasebe anelungelo lokunyamekela. Ngoko, zeziphi izifo ezibonisa iMRI yengqondo:
- ukubetha ;
- i-meningitis;
- encephalitis;
- neoplasms;
- iimpazamo ekuphuhlisweni;
- izizathu zokuhluthwa;
- nzakala;
- iziphazamiso zendlebe kunye namehlo;
- I-Vascular pathology;
- multiple sclerosis nezinye izifo.
I-MRI yengqondo ngokuchaseneyo, ngokubanzi ichaza oko kwenzekayo kwiinqanawa zentloko. Uninzi lwezilwanyana zidibene ne-vasoconstriction okanye i-thrombosis kuzo. Yenziwa ngokuzisa into ekhethekileyo kwisitya, esifike kwimithambo yegazi yentloko kwaye ibonisa ngokucacileyo umfanekiso weklinikhi.
Kwaye, umzekelo, i-MRI yengqondo ngaphandle kokusebenzisa ngokungafaniyo ibonisa ukuba ihluphekile, ibonisa ubukho bama-cysts, izibhamu kunye nezinye iingxaki.
Ngokubanzi, uhlobo lovavanyo oluya kumiselwa luxhomekeke kwizikhalazo zesigulane. Ukuba akukho ziphilo ezibonakalayo, kwaye isigulane sikhala ngezikhwebu ezininzi, ukungahambi kakuhle, ukulahlekelwa kokulungelelaniswa, ngokokuqala okokuqala imbonakalo ye-MRI yengqondo kufuneka yenziwe, kwaye iya kubonisa ukuba yintoni na ukuba ihlolwe ngakumbi.
Ngomzimba we-MRI wengqondo, ngokuchaseneyo, ubonisa oko kufuneka kukhishwe ngaphandle: izibilini, ukungavumelekanga kwisakhiwo semithambo yegazi kunye namalungu kunye nezinye izifo.
Inqubo isebenza njani?
Ubungakanani bolu phando lufikelela kwisiqingatha seyure, xa kusetyenziswa ukungafani-ukuya kwimitha engama-45. Ngokwalo, ukuhlala kwisixhobo ngokukhuselekileyo, nangona kunjalo, ukuba ngaphakathi, isigulane sinokungonwabi. Kulo lonke ixesha kufuneka lilale, kuba nayiphi na intshukumo iyakwazi ukuphazamisa umphumo kwaye unike umfanekiso ongalunganga.
Ngexesha le-MRI, isigulane sisodwa ekamelweni, kodwa uchwepheshe webhanki unokuthetha naye usebenzisa uxhulumaniso olukhethekileyo.
Akukho nkcazo, njengoko kunjalo, kwinkqubo,
- Xelela malunga nokukhulelwa.
- Susa izityezelo zensimbi, izithsaba, iinwele zeenwele kunye nezinye izinto.
Njengoko siphelo, kunokuthiwa ukuba ukubonakala kwe-imagination magnetic resonance kuye kwaba yimpumelelo yangempela kwingcaciso yezifo kunye nezizathu zazo. Ngoko ke, ukuze ufumane ukuba i-MRI iya kubonisa, umzekelo, isifo seengqondo, umntu akanakuzazaza: kuya kubonisa, kungekhona nje kuphela. Le ndlela iyakwazi ukucacisa ezininzi izifo, kwaye njengoko sisazi, ukuxilongwa ngokuchanekileyo sele kuvele i-50% yeempumelelo.
