I-MRI yesibindi ithathwa njengeyona ndlela ebonakalayo yokubonisisa eli lilungu langaphakathi. Le ndlela isekelwe kwiimpawu zamagnetic ze-proton-elements, ezikhoyo kuzo zonke iinxalenye zomzimba womntu. Kulo xesha lo kukhangela ukuba kunokwenzeka ukuchonga iziganeko zezilwanyana ezininzi.
I-MRI yesibindi ibonisa ntoni?
Siyabulela kule nkqubo yokuxilonga unga:
- ukuchonga i-foci echaphazelekayo ngesifo;
- ukuvavanya imeko yeemvini kunye nemithambo ehambelana nenkqubo yebhiliyari;
- tshekisha imeko ye-lymph nodes;
- ukufumanisa i-pathology, njl
Le nkqubo iboniswe ekunqumeni ukuguqulwa kwesifo (umzekelo, i-cirrhosis). Kwakhona kwenziwa ukuba kuhlolwe imeko yezitho zangaphakathi emva kokulimala komonakalo kwisisu esiswini.
Le nkqubo yokuxilonga ayithathi ixesha elide. Kuphela, njengommiselo, malunga nesiqingatha seyure. Umqathango kuphela omele ugcinwe ngethuba le-MRI yesibindi lugqibelele ukungahambi kakuhle kwesigulane. Ngaphandle koko, akunakukwazi ukufumana ulwazi oluchanekileyo kwimeko ye-bile duct system.
Ixabiso lokwazisa lwenkqubo yokuxilonga ngokuchaseneyo liphezulu kakhulu kunelo ndlela eqhelekileyo. Oko kukuthi, yintoni ebonisa i-MRI yesibindi ngokuthelekisana, inceda ukuhambisa ukuxilongwa okuthembekileyo.
Umgaqo we-MRI yesibindi ngokuchaseneyo ngolu hlobo lulandelayo: "i-amplifier" ngokuhamba kwegazi ithathwa kuwo onke ama-capillary kunye neeseli. Ngenxa yoko, zonke iiseli zelungu ziyasebenza (zombini ogulayo kunye nempilo). Indlela abasabela ngayo kwi-field magnetic field, kwaye isebenza njengesiseko sesigqibo malunga nesimo se-excretory system. Kwaye nje ngeziyobisi ezichaseneyo, ngokuqhelekileyo izisombululo, eziqulethe i-gadolinium, ziyasetyenziswa. Ukungqinelana nokuphunyezwa kwale nkqubo kukhulelwa, kunye nokunyanzeliswa kweengxaki zokukhawuleza. Ukongeza, musa ukwenza inkqubo kunye
Ukulungiselela isisindo seMRI sesibindi
Le nkqubo yokuxilonga yenziwa kuphela kwisisu esingenalutho. Kwaye oku kuthetha ukuba kwiiyure ezingama-5 ukuya kwe-6 ngaphambi kokuba u-tomography ufanele ubaleke ukutya.
Ukuba ukuxilongwa ngokuchaseneyo kwenziwa, ukulungiswa kwenkqubo enjalo kubandakanya ukufakwa kwe "amplifier". Faka ukungqungquthela komzimba kufuneka uhambe kancane. Ngokomzekelo, ukuba i-MRI yesibindi isenziwa nge- hemangioma , loo nto kufuneka ilawulwe ngokukhukhumeza. Ngokuqhelekileyo, oku kufuna ixesha elongezelelweyo.
