Kukho iindlela ezininzi zokuxilonga, kodwa i-CT yesifuba inokubona ukuba neengxaki ezincinci njenge-cholesterol plaques kwiindonga zeempahla kunye nezicubu ezimbalwa ngamamithamitha ngobukhulu. Nangona kunjalo, ngokuthe rhoqo i-CT isetyenziselwa ukuqinisekisa ubungqina bokuqala, ukufundwa kwamalungu esifubeni kunye nomsebenzi wabo.
I-CT scan yesifuba?
Ngoncedo lwe-CT yesitho sesifuba, nokuba kukho ukuphazamiseka kuncinci, okubaluleke kakhulu xa kungenelelo olungenelelo, unyango olunzulu okanye unyango lwezilwanyana ze-oncological. Ngokuqhelekileyo izibonakaliso zenkqubo zi:
- intlungu kwisifuba sezinto ezihlukeneyo;
- ukuphefumula, ukukhwehlela okungapheliyo;
- ukuphazamiseka kwebhande lomthwalo, umgudu;
- ukukrokra kwe-tumor kunye nokusekwa kwendawo yayo ngqo;
- ukuqinisekiswa kokuxilongwa kwimeko ye- emphysema okanye isifo sofuba, isifo se-pneumonia;
- ukucwangcisa i-chemotherapy kunye ne-radiation kunyango lomhlaza;
- imisebenzi yokucwangcisa esifubeni;
- izifo zeenqanawa zobunzima obuhlukeneyo, i-thrombosis, i-pulmary embolism;
- iziphazamiso emsebenzini weentliziyo, i-aortic dissection;
- akunakwenzeka ukuchonga isifo usebenzisa i-X-ray kunye ne-ultrasound.
Njengomthetho, i-CT yesifuba okanye ngaphandle kokungafani imiselwe ngumgqirha oya kwiiyo. Isigulane asikwazi ukufaka le nkqubo ngokwayo. Ukuba unesidingo sokwenza uviwo oluqhelekileyo ngenxa yeemeko ezingasebenziyo, okanye i-heredity ephosakeleyo, unokufaka isicelo seenkonzo kwiiklinikhi yokuxilonga yangasese.
Ukulungiselela i-CT yesifuba
Ukuze wenze i-CT ye-thorax, akukho luqeqesho olukhethekileyo olufunekayo. Ngaphambi kwenkqubo, isigulane sidinga kuphela ukususa zonke izinto zesebe kunye neengubo zokugqoka, sigqoke kwiingubo zokukhanya ezikhululekile kwaye zibeke umonde-ngokomyinge uviwo luhlala kwi-20 imizuzu ukuya kwiiyure enye kunye neyure, kuxhomekeke kwimiqulu yendawo yokufunda kunye neenkcukacha zayo.
Ukuqhuba i-tomography yekhompyutha uza kunikwa ukuba ulale etafileni ekhethekileyo, eya kuqhubela phambili kwi-scanner. Ngaloo ndlela, i-tomograph ihamba malunga netafile ngokuvuthayo, isebenzisa i-x-ray, izitho eziguquguqukayo zentsimbi. Ngokuxhomekeke ekuxininiseni kwezicubu zezinto ezahlukeneyo, le mibala ingabonakaliswa, okanye ifakwe. Ngenxa yoko, ikhomputha ifumana izicucu ezichanekileyo zequmrhu ngalinye ukusuka kumacala angaphakathi nangaphandle kwaye ibuyisela imodeli emithathu yendawo yophando. Oku kuvumela ukugqiba i-metastases encinci kunye ne-pathologies encinci kumsebenzi we-cardiovascular system, izibilini zokuphefumula, ukugaya kunye nezakhiwo ze-musculoskeletal.
I-CT yesifuba ngokuchaseneyo kuyimfuneko ukulandelela ngakumbi umsebenzi weentliziyo, ukuhamba kwegazi ngeempahla kunye nomsebenzi wemiphunga. Ngaphambi kokuba isicatshulwa sokuchasana singeniswe nge-intravenously, okanye ngomlomo, isigulane akufanele sidle iiyure ezingama-4 phambi kwenkqubo. Kwakhona kuyimfuneko yokwenza uvavanyo olupheleleyo lwegazi kunye neemvavanyo ezivakalayo ze-iodine kunye neziphumo zayo.
Inkqubo ngokwayo ikhuselekile, kodwa kubantwana kunye nabasetyhini abakhulelweyo kufuneka ukuba kwenziwe kuphela xa kufuneka ngokukhawuleza.
Ziziphi izifo ezinokufunyanwa nge-CT yesifuba?
Iindidi zezifo ezinokumiselwa ngoncedo lwe-tomography olucatshulwa kakhulu, lubandakanya zonke izitho kunye neenkqubo ezikuloo ndawo ye-sternum. Ezi ziquka:
- i-pathology ye-mediastinum, i-aorta, intliziyo;
- ukuqokelela kwamanzi aphuma kwimvelaphi eyahlukeneyo;
- i-bronchiectasias, i-emphysema, umhlaza wamaphaphu ;
- izifo ezithathelwanayo zenkqubo yokuphefumula;
- iziphazamiso zesakhiwo seethambo zezimbambo, umgudu;
- i-metastases ye-tumors, ihlume zibe yimbumba, umongo we-bone, umgudu.
