Izikhalazo zesiguli ezinhlokweni eziningi, isizungu, izinguquko emsebenzini wezinzwa yizizathu ezizwakalayo zokuxhumana nochwepheshe. Ngokuvamile, ngemva kokuhlola isiguli nokuqoqa i-anamnesis, udokotela uncoma ikhompyutha ye-tomography scan.
I-CT scan ibonisa ngani?
Labo abanikezwa inqubo yokuxilonga, kufanele wazi ukuthi yini i-CT scan ibonisa ubuchopho.
Izimpawu zokuqokwa kwe-CT yobuchopho ziyi:
- ukuhlukunyezwa okuhlobene nokuphuka kwamathambo e-skull noma ukulimala kwezakhi zobuchopho;
- i-cerebral hemorrhages;
- ukusola ngokuba khona kwezicubu noma izidakamizwa ebuchosheni;
- ukuwohloka okwehlulekayo kwezicubu zezinzwa;
- isifo, isifo senhliziyo;
- i-pathology yemikhumbi ye-cerebral ( aneurysm , njll)
- izinqubo zokuvuvukala kwamadoda (i-meningitis, i-encephalitis, i-abscess);
- ukuhlukumezeka kokuthuthukiswa kwengqondo (i-hydrocephalus, njll).
Futhi, ukuhlolwa kwe-CT kunikwa lapho kuhlela ukusebenza ebuchosheni nokuqapha isimo sezinto kanye nezingxenye zobuchopho ngemva kokuhlinzwa.
Iyiphi indlela ye-tomography ehlanganisiwe?
I-tomography yekhompyutha ibhekisela ezindleleni ezingenabuhlungu futhi eziphephile zocwaningo lwe-hardware.
Ngokwezobuchwep, inqubo ye-CT ingachazwa kanje: ukuhlolwa usebenzisa i-computer ye-tomography ikuvumela ukuba uthole uchungechunge lwezigcawu (imihlobiso yamathambo) ebuchosheni ngesimo sezithombe esikrinini sokuqapha kanye nezinombolo zezithombe, lapho ufunde ukuthi udokotela utholaphi isifo. Uma kuthathwa isicwecwe samakhompiyutha amathathu-ntathu, isifundo sibhalwe ku-CD-ROM.
Indlela eyithuthukisiwe kakhulu i-tomography yamakhompiyutha, ane-resolution engcono kakhulu yendawo. Ngaphezu kwalokho, ukuvuthwa kwe-tomography kudala umthwalo ophansi we-radiation emzimbeni.
Ukuze kutholakale izinguquko ze-pathological esigabeni sokuqala, ngokuhambisana nobufakazi bukadokotela, i-CT engiography yenza - ukuhlolwa kwezakhiwo zobuchopho nezitsha ze-cerebral esebenzisa i-medium contrast. Enye yezindlela ezintsha zokuthola izinguquko ze-pathological in the brain, ngokufanisayo, "isimo embryonic", is positron emission tomography (PET). Lapho senza i-PET CT yobuchopho nge-myotonin, i-glucose, i-sodium diatrizoate noma enye i-tracer, umehluko usungulwa emzimbeni. Ngokusakazeka kancane kuwo wonke ama-system kanye nama-tissue, i-agent ehlukile ekuhlungeni okukhulu iqoqa ezindaweni lapho kukhona khona izinqubo ezithintekayo. Emfanekisweni wobuchopho, amaqoqo e-tracer abonakala kakhulu, futhi lokhu kusiza ukukhomba ukugula lapho kuqala ukuthuthukiswa kwayo.
I-Tomogram yobuchopho
Ubuningi besendwangu esithombeni bubonakala kumhlophe nangomnyama, kanye nasemathunzini wegrey. Ithemba lincane kakhulu, futhi linombala omhlophe ku-tomogram. Into
Ku-tumors, i-edema, i-hemomomas engavimbayo kanye nezinye izifo zobuchopho emcimbini, izindawo ezinemibala emnyama noma elula kunezicubu ezizungezile zihlukile. Ngaphezu kwalokho, ama-ventricle, imisele, njll kubonakala ngokucacile.
Ngokususelwa kwimiphumela ye-tomography ehlanganisiwe, udokotela ubeka ukwelashwa noma unikeza ukudluliselwa kwesazi sephrofayli ehambisana nesifo.
