Le isithwebuli sesisu inqubo yeizithombe ngezinhloso zokuxilonga ezihlanganisa "ukushanela" i isifunda sesisu ukwakha izithombe zesigaba. Lawa afundisa kakhulu kunalawo ama-x-ray avamile, futhi avumela ukubonakala kwezitho zendawo yesisu: isibindi, amathumbu amancane, isisu, amanyikwe, ikholoni, i-spleen, izinso, njll.

Inqubo isetshenziswa X-ray ezimuncwa ngokuhlukile kuye ngokuminyana kwezicubu, kanye nekhompiyutha ehlaziya idatha bese ikhiqiza izithombe ze-point-by-point cross-sectional yezakhiwo ze-anatomical zesisu. Izithombe ziboniswa ngombala ompunga esikrinini sevidiyo.

Qaphela ukuthi igama elithi “scanner” empeleni igama lensiza yezokwelapha, kodwa ngokuvamile lisetshenziselwa ukubiza ukuhlolwa. Siphinde sikhulume mayelana i-tomography yekhompyutha noma ka i-scanographie.

Udokotela unikeza ukuskena kwesisu ukuze kutholwe isilonda esithweni noma esithweni esisendaweni yesisu noma ukwazi ukuthi singakanani. Ukuhlolwa kungenziwa ngokwesibonelo ukuze kutholwe:

• imbangela a ubuhlungu besisu noma ukuvuvukala

• a i-hernia

• imbangela a imfiva ephikelelayo

• ubukhona be uyafa

• we ezinso (i-uroscanner)

• noma i-appendicitis.

Isiguli silala ngomhlane izingalo zaso zingemuva kwekhanda laso, futhi sibekwe phezu kwetafula elikwazi ukushelela ngomshini omise okwendandatho. Lokhu kuqukethe ishubhu le-x-ray elizungeza isiguli.

Isiguli kufanele sithule ngesikhathi sokuhlolwa futhi kungase kudingeke sibambe umoya isikhathi esifushane, ngoba ukunyakaza kubangela izithombe ezilufifi. Izisebenzi zezokwelapha, ezibekwe ngemva kwengilazi yokuzivikela kuma-X-ray, ziqapha ukuqhubeka kokuhlolwa kuyi-computer futhi zingakwazi ukuxhumana nesiguli ngombhobho.

Ukuhlolwa kungase kudinge umjovo wangaphambili we-a i-contrast medium i-opaque kuya ku-X-ray (ngokusekelwe ku-iodine), ukuze kuthuthukiswe ukufaneleka kwezithombe. Ingajovwa ngomjovo ngaphambi kokuhlolwa noma ngomlomo, ikakhulukazi kwi-CT scan yesisu.

Ngenxa yezingxenye ezincane ezitholwe ukuhlolwa, udokotela angakwazi ukubona izifo ezihlukahlukene, njenge:

• ezinye izinhlobo zomdlavuza : umdlavuza wamanyikwe, izinso, isibindi noma ikholoni

• izinkinga nge-gallbladder, isibindi noma amanyikwe: isifo sesibindi esidakayo, i-pancreatitis noma i-cholelithiasis (i-gallstones)

• we Izinkinga zezinso : amatshe ezinso, i-uropathy evimbelayo (i-pathology ebonakala ngokuhlehla kwesiqondiso sokugeleza komchamo) noma ukuvuvukala kwezinso

• un ithumba, i-appendicitis, isimo sodonga lwamathumbu, njll.
