I-tomography ekhompyutheni yamathumbu ikwabizwa ngokuba yi-colonoscopy. Ukufumana umfanekiso opheleleyo wengingqi yangaphakathi yamathumbu, ikholoni, amanani amancinci we-X-ray irradiation asetyenziswa ngexesha lokuskena ngaphandle kokungenelela ukungena. Inkqubo ayibuhlungu, iyenzeka ngokungahambi kakuhle kwaye ifikeleleke ngaphakathi kwemizuzu engama-15.
Ukulungiselela ukuhlaziywa kwe-tomography yamathumbu
Ukulungiselela inkqubo ye-CT ngolu hlobo lulandelayo:
- Ngeentsuku ezi-2 ungathathi ukutya kwegesi kunye nokusela (iimfuno, isinkwa esimnyama, imifuno eluhlaza kunye neziqhamo, iziphuzo ze-carbonated, ubisi kunye nemveliso yobisi).
- Usuku olungaphambi kokufunda, lisela isilayidi (i-Fortrans okanye i-Duffalac).
- Ngomso wekusasa, siphuze i-laxative kwaye wenze i-enema ehlambulukileyo.
- Ngaphambi kwenkqubo, susa zonke izinto zetsimbi, kuquka amazinyo amanga.
- Isigulane sicelwa ukuba sigqoke isambatho esikhethekileyo ixesha lokufunda.
Yintoni ebandakanyiweyo ekufundweni kwe-tomography ekhompyutheni yamathumbu?
Ukuhlolwa kwamathumbu nge-CT indlela kuvumela ukuhlola izi zifo zilandelayo:
- iinkqubo ezivuthayo kunye nezizodwa zokuvuvukala emathunjini;
- i-colitis;
- isilitis;
- Sesifo sikaCrohn ;
- isifo seliliac;
- ukugula ngokubambelela;
- ukuphuma kwi-digestive tract;
- Amathumbu omzimba wesisu - iipolps, i-lymphomas, umhlaza;
- izilonda zesisu zamathumbu;
- iingxaki zesilonda esiswini.
I-tomography ekhompyutheni yamathumbu amakhulu
I-Tomography ilandelayo:
- Isigulane sifakwa kwietafile ezikhethekileyo.
- Kwi-rectum ukuya kwi-5 cm enzulu ityhulwa encinci
inani elincinci lomoya lisetyenziselwa ukusasaza umthamo nokuphucula umgangatho womfanekiso. - Emva koko itafile kunye nesigulane ifowuni kumshishini okhethekileyo we-X-ray, efana ne-bagel enkulu.
- I sixhobo sijikeleza ngetafile ngokujikeleza kwaye sithatha imifanekiso yecala ngokucwangciswa kwimizi eyahlukeneyo. I-tomograph ivelisa umfanekiso we-3D wesithili sangaphakathi samathumbu amakhulu.
Ukwahlula okucatshulwe i-tomography yamathumbu
Uhlu lodidi lwe-iodine lungasetyenziselwa ukuhlolwa kwamathumbu omzimba. Isilwayo sijojowe nge-enema, singabandakanyi kwaye sinamathambo kuphela emathunjini emathumbu.
