I-CT yamaphaphu isesinye sezifundo ezidume kakhulu. Konke ngenxa yokuchithwa kwayo nokungabi nobuhlungu. I-Tomography ikuvumela ukuba ubone izifo ezihlukahlukene. Ngaphezu kwalokho, lokhu kwenza ngisho naseziqenjini zokuqala, lapho izindlela eziningi zokuhlola umzimba zingenamandla.
Ngabe i-CT yemaphaphu iphi?
Lesi sifundo se-ray ray. Kodwa ngokungafani ne-X-ray yendabuko, i-tomography ehlanganisiwe ayiyona eyingozi kakhulu. Yibani, njengomthetho, ukuze kucacise ukuthi kumaphaphu kanye nezitho zomphakathi we-mediastinum kube khona izinguquko. Okusho ukuthi, inqubo kufanele iyenziwe ngemuva kwe-radiography noma i-fluorography kuphela uma imiphumela yezifundo ibangela ukusola.
Ngokujwayelekile CT ithunyelwa ku:
- ukutholakala kwemizimba yangaphandle e-bronchi;
- ukusola ngokuba khona kwezicubu ezinhle noma ezimbi;
- izifo ze-sternum;
- ukuphazamiseka esikhwameni se-pericardial;
- izifo ze-bronchiectasis;
- ukusola kokubunjwa kwe-volumetric ye-mediastinum;
- izinguquko kwisakhiwo samaphaphu;
- izinqubo zokuvuvukala ezithombeni zellimini esifubeni;
- izifo ze-thymus gland.
I-CT scan ibonisa ngani?
I-tomography yekhompyutha inikezwa ukuthola izifo zamaphaphu ezinjenge-embolism engapheli noma isifo sofuba. Ngaphezu kwalokho, lolu cwaningo lubonisa ukuba khona kwezicubu nezinqubo zokuvuvukala emzimbeni. Ngokuvamile, kunqunyelwe iziguli ezinezifo ezisebenzayo ezibangelwa ukutholakala kwezifo zamakhemikhali.
Ukuchithwa kwamaphaphu CT kunolwazi mayelana nesimo samaphaphu, i-pleura, i-bronchi, i-trachea, i-artery yamayeri, i-vena cava ephakeme, i-thoracic aorta. Uma kutholakala isisu, incazelo ephelele ye-tumor nokusabalalisa kwayo kufanele ibe khona esiphethweni.
CT yamaphaphu ngokuphambene
Le nqubo ivame ukubizwa nge-angiography. Lenziwa ngokuyinhloko kuphela ezimweni lapho ukutholakala kwesisu kuqinisekiswa khona. Ukutadisha ngezinto ezihlukileko kunikeza idatha enembile nakakhulu mayelana ne-tumor kuphela, kodwa futhi nesimo sezinto.
I-CT ngokuphambene inquma:
- ukutholakala kwama- atherosclerotic plaques ;
- aneurysms;
- i-pulmonary artery thromboembolism;
- i-pneumonia;
- isifo sofuba ;
- izindawo ezitsheni ezinezimoto eziphazamisekile;
- i-caronoma ye-bronchial.
Nge-pneumonia ku-CT emaphashini, i-foci yokuvuvukala ibonakala. I-Tomography yokuxilongwa kwalesi sifo ayisebenzisi ngaso sonke isikhathi. Kunqunywe kulawo maqiniso lapho ukuhlolwa kwe-X-ray evamile kwemiphumela edingekayo engakaze kuboniswe.
I-CT yamaphaphu?
Ukuze kusetshenziswe inqubo, kusetshenziswe idivayisi ekhethekile, yangaphandle ifana nomgwaqo wesigcawu esikhulu. Ngaphakathi, itafula elihambayo linamathele kulo. Idivayisi ixhunywe kukhompyutha futhi ilawulwa yiyo.
Isimiso se-CT sisekelwe eqinisweni lokuthi ama-tissue ahlukahlukene emzimbeni womuntu aphuthelwa ama-X-ray ngokungalingani. Lokho okuvuthayo, ukusabalalisa ukukhanya, okuncane kakhulu - kuyifake. Izimo zenzeka ngesikhathi ngasinye senqubo. Izingoma zilungisa, futhi emva
Ngaki kaningi ukuhlolwa kwe-CT kungenziwa?
Ngoba le nqubo ihlobene ngokuqondile nemisebe ye-X ray, kaningi ayinakwenziwa. Ngaphambi kokuhlolwa, udokotela kufanele atadishe ikhadi lomguli ngokuningiliziwe futhi athole umthwalo wemisebe awutholile.
Ukwenza i-tomography yekhomputha, ngisho noma umkhawulo wokuchayeka udlulile, kuyadingeka kuphela uma kwenzeka ukuthi ingasindisa impilo, futhi ayikho enye indlela yokuxilonga engafaneleki ngesikhathi esisodwa.
Okuhlukile kokuphuma kwesimo kungabuye kube nokukhanya kwe-CT, okuyinto eyanciphisa kakhulu umthamo we-irradiation eyamukelwe.
