I-tomography ehlanganisiwe yamathumbu ibizwa nangokuthi i-colonoscopy yangempela. Ukuthola isithombe esiphelele sendawo yangaphakathi yamathumbu, ikholoni, ukulinganisa okuncane kwe-X-ray irradiation kuyasetshenziswa ngesikhathi sokuskena ngaphandle kokungenelela okungenayo. Le nqubo ayinandaba, iyabangela ubuhlungu futhi ngokushesha - kungakapheli imizuzu engu-15.
Ukulungiselela amakhompiyutha amathumbu amathumbu
Ukulungiselela inqubo ye-CT kanje:
- Ngezinsuku ezimbili ungathathi ukudla okwenziwe yi-gas kanye neziphuzo (izitshalo, isinkwa esimnyama, imifino eluhlaza nezithelo, iziphuzo ze-carbonate, ubisi nemikhiqizo yobisi).
- Usuku ngaphambi kokutadisha, uphuze i- laxative (i-Fortrans noma i-Duffalac).
- Ngesonto ekuseni, uphuze i-laxative bese wenza i-enema yokuhlanza.
- Ngaphambi kwenqubo, susa zonke izinto zensimbi, kufaka phakathi amazinyo amanga.
- Isiguli siceliwe ukuba sigqoke ingubo ekhethekile yesikhathi sokufunda.
Yini ehlanganisiwe ekucwaningweni kwe-tomography ye-computed yamathumbu?
Ukuhlolwa kwamathumbu nge-CT indlela kuvumela ukuhlola izifo ezilandelayo:
- izinqubo ezivuthayo neziqondile zokuvuvukala emathunjini;
- i-colitis;
- i-ulcerative colitis;
- Isifo sikaCrohn ;
- isifo se-celiac;
- ukugula okunamathela;
- ukuphuma egazini lokugaya;
- Izicubu zomzimba ezisemathunjini - ama-polyps, i-lymphomas, umdlavuza;
- izilonda zamathumbu zamathumbu;
- izinkinga zesilonda esiswini.
I-tomography ehlanganisiwe yamathumbu amakhulu
I-Tomography yile ndlela elandelayo:
- Isiguli sifakwa etafuleni elikhethekile.
- E-rectum kuya ku-5 cm ejulile kufakwe ithubhu encane
inani elincane lomoya lisetshenziselwa ukusabalalisa ugundane nokuthuthukisa ikhwalithi yesithombe. - Khona itafula nesiguli libiza ngomshini okhethekile we-X-ray, ofana ne-bagel enkulu.
- Idivaysi ijikeleza itafula ngokuvunguza futhi ithatha izithombe ungqimba ngendlala kusuka emazingeni ahlukene. I-tomograph ikhiqiza isithombe se-3D sesifunda sangaphakathi samathumbu amakhulu.
Ukuqhathaniswa komthamo we-tomography wamathumbu
Ukungafani okune-iodine kungasetshenziselwa ukuhlolwa okungcono kwamathumbu. Isidakamizwa sijojowe nge-enema, hhayi sidonsa futhi sidonsa kuphela umuthi wamathumbu emathunjini.
