Kunezindlela eziningi zokuxilongwa, kodwa i-CT yesifuba ingathola ngisho nezinkinga ezincane ezinjengama-cholesterol plaques ezindongeni zezimpahla nezicubu ngamasentimitha ambalwa ngesayizi. Kodwa-ke, kaningi ukuhlolwa kwe-CT kusetshenziselwa ukuqinisekisa ukuhlolwa kokuqala, ukuhlolwa kwezitho zesifuba nomsebenzi wabo.
Yini i-CT scan yesifuba?
Ngosizo lwezitho ze-CT zesifuba, ngisho nokuphazanyiswa okuncane kunazo zonke kungatholakala, okubaluleke kakhulu lapho ukungenelela kokuhlinzwa, ukwelashwa okunamandla noma ukwelashwa kwezifo ezingokwemvelo kuyadingeka. Ngokuvamile izinkomba zezinqubo ziyi:
- ubuhlungu esifubeni sokuhlukaniswa okuhlukahlukene;
- ukuphefumula, ukukhwehlela okungapheli;
- ukuphazanyiswa kwebhande lehlombe, umgogodla;
- ukusola ngesisu nokusungulwa kwendawo yaso ngqo;
- ukuqinisekiswa kokuthola ukuxilongwa uma kwenzeka u- emphysema noma isifo sofuba, i-pneumonia esivamile;
- ukuhlela i-chemotherapy kanye nemisebe ekwelashweni komdlavuza;
- ukuhlela imisebenzi esifubeni;
- izifo zezimpahla ezinzima kakhulu, i-thrombosis, i-embolism ye-pulmonary;
- ukuphazamiseka emsebenzini wenhliziyo, i-aortic dissection;
- akunakwenzeka ukukhomba lesi sifo besebenzisa i-X-ray kanye ne-ultrasound.
Njengomthetho, i-CT yesifuba noma ngaphandle kokuqhathaniswa ishiwo udokotela oya khona. Isiguli asikwazi ukungena kule nqubo yedwa. Uma unesidingo sokuqhuba ukuhlolwa komkhuba ngenxa yezimo zokusebenza ezingalungile, noma i-heredity engafanele, ungafaka isicelo semisebenzi emtholampilo wangasese wokuxilonga.
Ukulungiselela i-CT yesifuba
Ukuze wenze CT of the thorax, akukho ukuqeqeshwa okukhethekile okudingekayo. Ngaphambi kwenqubo, isiguli sidinga kuphela ukususa zonke izesekeli zensimbi nezingubo zokugqoka, sigqoke izingubo zokukhanya ezikhululekile futhi sibe nokubekezela - ngokwesilinganiso uhlolo luvela emaminithini angu-20 kuya emahoreni owodwa nengxenye, kuye ngokuthi umthamo wendawo yokufunda kanye nemininingwane yayo.
Ukuqhuba i-tomography yekhompuyutha uzonikezwa ukulala etafuleni elikhethekile, elizoqhubekela phambili ngaphakathi kwesithwebuli. Ngokufanayo, i-tomograph iyasondela etafuleni ngokuvunguza, isebenzisa ama-x-rays, izitho eziguquguqukayo ze-thorax. Ngokuya ngobukhulu bezicubu zezakhiwo ezihlukene, le mibala ingabonakaliswa, noma ifakwe. Ngenxa yalokho, ikhompiyutha ithola ukusikeka okunembile kwesigungu ngasinye kusuka ezinhlangothini zangaphakathi nangaphandle futhi ibuyisela imodeli yesithathu yomkhakha ophenywayo. Lokhu kuvumela ukucacisa ngisho nemithi emincane ye-metastase kanye ne-pathologies encane emsebenzini wesimo senhliziyo, izinzwa zokuphefumula, ukugaya kanye nezakhiwo ze-musculoskeletal.
I-CT yesifuba ngokuphambene kuyadingeka ukuze ulandele ngokujulile umsebenzi wenhliziyo, ukuhamba kwegazi ngokusebenzisa izitsha kanye nomsebenzi wamaphaphu. Ngaphambi kokuba isixazululo sokuphambene sijojowe ngaphakathi, noma ngomlomo, isiguli akufanele sidle amahora amane ngaphambi kwenqubo. Kubuye kudingekile ukuba kwenziwe ukuhlolwa okuphelele kwegazi kanye nokuhlolwa kwe-allergen for iodine kanye neziqephu zayo.
Le nqubo ngokwayo iphephile, kodwa kubantwana nabesifazane abakhulelwe kufanele kwenziwe kuphela uma kudingekile.
Iziphi izifo ezingatholakala nge-CT yesifuba?
I-spectrum yezifo ezinganqunywa ngosizo lwe-tomography ehlanganisiwe kakhulu, ihlanganisa zonke izitho nezinhlelo ezisendaweni ye-sternum. Lokhu kufaka:
- i-pathology ye-mediastinum, i-aorta, inhliziyo;
- ukuqoqwa kwamanzi aphuma emlandweni wesicoco;
- i-bronchiectasias, i-emphysema, umdlavuza wamaphaphu ;
- izifo ezithathelwanayo zesimiso sokuphefumula;
- ukuphazamiseka kwesakhiwo samathambo wezintambo, umgogodla;
- ukuqubuka kwezidumbu, zihlume zibe izitho, umnyofu wesifuba, umgogodla.
