Ukuthuthukiswa kwemithi yokuxilonga okwamanje kukuvumela ukuba usungulwe isifo noma ukukhubazeka esigabeni sokuqala. Lokhu kusebenza ngisho nasimisweni esinzima kangaka somzimba womuntu njengengqondo yomuntu. Isimiso sokuskena kwesendlalelo ngesendlalelo sisekelwe ezindleleni zocwaningo lobuchopho be-CT ne-MRI. Lokhu ukufana kwabo okuyinhloko. Ake sithole ukuthi umehluko phakathi kwe-CT ne-MRI yobuchopho, nokuthi yini ephumelela kakhulu futhi enembile kune-MRI noma i-CT.
Umehluko phakathi kwe-MRI no-CT yobuchopho
Uma ukhuluma ngokujwayelekile, ke phakathi kokuxilongwa kobuchopho yi-CT ne-MRI kukhona umehluko omkhulu, ohlanganisa:
- ubuchwepheshe bedivaysi;
- izinga lokuzwela kwedivayisi.
Isenzo se-tomograph yekhompiyutha isekelwe emisebentini ye-x ray, eqondiswa emathisheni, enikeza umbono wesimo somzimba salo, ubungako bayo. I-CT - le divayisi ijikeleza i-axis eyinhloko - umzimba wesiguli, eveza umfanekiso wesigungu esuswa (kulokhu, ubuchopho) ekuhloleni okuhlukile. Izingxenye ezitholakale ngesikhathi sophenyo zifingqiwe, zicutshungulwa kukhompyutha, futhi kutholakala umphumela wokugcina, ohunyushwa ngumchwepheshe emkhakheni.
I-MRI ihluke ngokuthi umsebenzi wedivaysi uhileleke emasimini anamandla amakhulu. Ngokwenza ama-athomu e-hydrogen, zivumelanisa lezi zinhlayiyana ezihambisana nendawo eqondiswayo. I-radio-frequency pulse eyenziwa yile divayisi iyingqayizivele emkhakheni we-magnetic, ukudlidliza kwamaseli ku-resonate, futhi yilokho okwenza kube lula ukuhlela izithombe eziningi ezilayishiwe. Amanki e-MR yanamuhla ane-design evulekile, ebaluleke kakhulu ezigulini eziphethwe yi-claustrophobia.
Izinkomba zokuqokwa kwe-CT ne-MRI yobuchopho
Kulezi ziguli ezinikezwe inqubo yokuhlolwa kobuchopho, umbuzo ubaluleke kakhulu: yini engcono kune-MRI noma CT scan? Cabangela kokubili izinqubo zokuxilonga ezivela esikhundleni sezokwelapha.
Ukusebenzisa i-MRI, kungcono ukutadisha izicubu ezithambile (imisipha, imithambo yegazi, ubuchopho, ama-disk intervertebral disks), futhi i-CT iphumelela kakhulu ekutadisheni izicubu ezinamafu (amathambo).
I-MRI ingcono kakhulu:
- i-pathologies yezingqimba zobuchopho;
- izilonda zesisindo esithambile;
- ukusola ukuvuvukala;
- ukuvuvukala kwezicubu zobuchopho ngenxa yesifo sokushaya isifo , ukuphefumula, njll;
- Izinguquko ezimbi emivinini ye-intracranial, pituitary gland.
I-MRI iphinde ibekwe ukungahambisani nemithi ebizwa ngokuthi i-radiopaque, ehilelekile ku-tomography ebhaliwe. Okubaluleke kakhulu kwe-MRI yilokho ayikho imisebe ekutadisheni. Yilokho okwenza inqubo ivikeleke kwabesifazane abakhulelwe (ngaphandle kwe-trimester yokuqala) kanye nabesifazane abalahlayo, kanye nezingane zaseminyakeni yokuqala nezinsana zasenkulisa.
Ngesikhathi esifanayo, i-MRI iphikisana nabantu abanamathelethi wensimbi, izimila, iminyango, njll.
I-CT inikeza ulwazi olunembile ekuhloleni:
- Izinguquko ze-atherosclerotic ohlelweni lwesisombululo;
- aneurysms ;
- izilonda zamathambo ama-cranial, amasinasi e-paranasal, ama-skeleton ebuso;
- i-traumas ye-cranium ethinta izakhi zobuchopho.
Uma sicabangela kokubili izinqubo ezivela kwesikhashana, i-CT scan yenye ingxenye yomzimba ihlala imizuzu engu-10, kuyilapho i-MRI scan ithatha imizuzu engaba ngu-30.
Kukhona umehluko ezindleko zocwaningo. I-tomography ye-computer yobuchopho ishibhile kakhulu, futhi imali yokubheka i-magnontic resonance, ngokulandelana, iphakeme. Ngaphezu kwalokho, idivayisi ye-MRI ephelele futhi ebiza kakhulu, iphakamisa ikhwalithi yezithombe, imali edingekayo ukukhokha inqubo yocwaningo.
