I-tomography ehlanganisiwe yobuchopho

I-tomography ye-computer yobuchopho - indlela yokuhlolwa kwe-X-ray, evumela ukuthola isithombe sezinto ezinhlobonhlobo ezihlukahlukene.

Yini i-tomography ye-computer yobuchopho ebonisa?

Ngama-tomography ekhompyutheni ebuchosheni, izifo ze-gray and white ubuchopho zibhekisisa, ukuphazamiseka emadodeni, izitsha nama-tissue azungezile. I-CT yobuchopho isiza ukukhomba ukuthi ukuvuvukala, ukukhomba izicubu ezinobungozi nezilimazayo, nokuthuthukisa ukungavamile ezinganeni.

Izinkomba ngenjongo yenkambiso yokuhlonza zimi kanje:

• ukuhlukumezeka ku-skull nge-fracture okusolakala ukuthi i-break and bone dislocation noma umonakalo ezakhiweni;
• imibono mayelana nokuba khona kwesisu endaweni yobuchopho, imetastasis ebuchosheni;
• ukuphazamiseka kwegazi, kuhlanganise, ngenxa yesifo noma isifo senhliziyo;
• ukuqinisekiswa kokukhona (ukungabikho) kwamathambo wemikhumbi ye-cerebral, aneurysms;
• ukuvuvukala kobuchopho (meningitis, encephalitis)
• ukuhlaziywa kwethambo lesikhashana elinokwehla okukhulu ekuzwa;
• ukwelashwa kwezicubu zesifo;
• ukwenza imisebenzi ebuchosheni.

Okungcono kakhulu ukuthi kungenzeka ukuxilongwa nge-CT ngisho nangomuntu osesimweni esibucayi, isibonelo, ngokulimala okungathí sina kobuchopho.

Njengazinqubo eziningi zokuhlola ze-hardware, i-tomography yesibalo sobuchopho inombhalo wokuncintisana, okufaka:

• ukungahambisani ne-iodine noma i-agent ehlukile;
• ukukhulelwa, ikakhulukazi ku-trimester yokuqala (i-X-ray ingalimaza ingane);
• isifo sobuhlungu obukhulu;
• i-hyperkinesis (ukunyakaza okungalawuleki);
• ukuhluleka kwezinso (ngenxa yezinkinga zokususwa okuhlukile).

Ngaphezu kwalokho, i-tomography ye-computed ayinconywa ngokuba nomama wokuncelisa, ngoba umehluko kalula ungene ebisi lwebele. Uma inqubo kufanele isetshenziswe, owesifazane uxwayiswa ukuthi phakathi nezinsuku ezimbili emva kokuhlolwa ingane akufanele ibelethwe.

Kwenzeka kanjani ukuthi ubuchopho bekhompuyutha buyenziwe?

Ukutadisha izakhiwo zobuchopho kwenziwa ngosizo lwe-CT scanner ne-X-rays. Ngokujwayelekile, i-agent ehlukanisa iodine-based based injected in the bloodstream ukuthuthukisa ukubonakala. Njengamanje, i-tomography ekhompiyutha enobuciko obusha, ephethe isinqumo esiphezulu sendawo futhi inikeza umthamo ophansi we-radiation emzimbeni.

Isiguli sitholakala etafuleni le-tomograph, eliya ekufakeni izixhobo. Ngaphakathi kwesithwebuli, imisebe iyaskenwa, futhi izithombe ezimnyama nemhlophe zikhonjiswa kwesikrini sokuqapha izingxenye zobuchopho, ngenxa yokuthi uchwepheshe uqhuba ukuhlaziywa okugcwele. Ukuhlolwa kwesimo sezingqondo zobuchopho kunikezwa ngokucabangela isimo sabo, ubukhulu, ubungako kanye nendawo.

Izimo eziyinkimbinkimbi futhi ezibizayo zokuhlolwa kobuchopho ziyi-imagery magnetic resonance (MRI) kanye ne-positron emission tomography (PET). Lezi zindlela zisenza sikwazi ukwethula ubuchopho emininingwaneni encane kakhulu. Ngaphezu kwalokho, nge-PET, izithombe zombala zezingxenye zobuchopho zikhiqizwa, okuvumela ukuxilongwa okunembile.

Yimiphi imiphumela ye-tomography ehlanganisiwe yobuchopho?

Ngezinye izikhathi iziguli zenqabe ukwenza i-tomography, ikholelwa ukuthi inqubo ibangela ukulimala okukhulu empilweni. Eqinisweni, ukuklanywa okhethekile kwedivaysi kuvumela ukunciphisa umthamo wokushisa imisebe okungenani, ngakho-ke amakhemikhali we-cerebral computed ayifaki isongela empilweni yesiguli, noma ngabe yenziwa ngokuphindaphindiwe isikhathi esifushane.
