I-CT yomphunga sele ibe yinto yezifundo ezidume kakhulu. Konke ngenxa yokuchaneka kwayo kunye nentlungu. I-Tomography ikuvumela ukuba ubone izifo ezahlukahlukeneyo. Ukongezelela koko, oku kwenzayo nakwiiyure zokuqala, xa ezininzi iindlela zokuhlola umzimba zingenamandla.
Iyiphi i-CT yemiphunga?
Oku kufundiswa kwe-x ray. Kodwa ngokungafani ne-X-ray yendabuko, i-tomography ekhompyutheni ayiyingozi. Mnike, njengomthetho, ukuze kucacise ukuba imiphaphu kunye namalungu omlamastinum kukho naluphi na utshintsho. Oko kukuthi, inkqubo kufuneka iyenziwe emva kwe-radiography okanye i-fluorography kwaye kuphela ukuba iziphumo zezifundo zibangela ukusola.
Ngokuqhelekileyo CT ithunyelwa kwi:
- ubukho bamaziko angaphandle kwi-bronchi;
- krokreka phambi kobuhlungu obuhle okanye obuhlungu;
- izifo ze-sternum;
- iziphazamiso kwi-bagic pericardial;
- izifo ze-bronchiectasis;
- ukukrokra ukubunjwa kwe-volumetric ye-mediastinum;
- utshintsho kwisakhiwo samaphaphu;
- iinkqubo zokuvuvukala kwi-lymph nodes kwisifuba;
- i-patmus ye-thymus gland.
I-CT scan ibonisa ntoni?
I-tomography yekhompyutheni yabelwe ukufumana izifo zamaphaphu ezinjenge-embolism engapheliyo okanye isifo sofuba. Ukongezelela, isifundo sichaza ubukho beentlungu kunye neenkqubo ezivuthayo emzimbeni. Ngokuqhelekileyo, imiselwe izigulane ezinezigulane ezithintekayo ezibangelwa ngumzimba we-inhalation of particles.
Ukuchithwa kwemiphunga ye-CT iqulethe ulwazi malunga nomzimba weemiphunga zamaphaphu, i-pleura, i-bronchi, i-trachea, umthambo we-pulmonary, i-vena cava ephezulu, i-thoracic aorta. Ukuba i-tumor ifunyenwe, inkcazelo epheleleyo yesifo kunye nokusabalalisa kwayo kufuneka ibe khona kwisiphelo.
I-CT yomphunga ngokuphambene
Le nkqubo ibizwa ngokuba yi-angiography. Yenziwa ngokukodwa kuphela kwiimeko apho ubukho be-tumor buqinisekiswa. Uphononongo oluneenkcukacha ezahlukeneyo lunikeza iinkcukacha ezichanileyo malunga ne-tumor kuphela, kodwa nakwiimeko zeempahla.
I-CT ngokuchaseneyo inquma:
- ubukho beepatros atherosclerotic ;
- aneurysms;
- umthambo we-pulmonary thromboembolism;
- pneumonia;
- isifo sofuba ;
- indawo kwiinqanawa ezineendlela eziphazamisayo;
- i-bronchial carcinoma.
Nge-pneumonia kwi-CT kwimiphunga, i-foci ye-inflammation ibonakala. I-Tomography yokuxilongwa kwesi sifo ayisoloko isetyenziswa. Kufuneka kulawo matyala xa uviwo oluqhelekileyo lwe-X-ray lweziphumo ezifunekayo alubonwanga.
I-CT yemiphunga?
Kule nkqubo, kusetyenziswe iifayili ezikhethekileyo, ukubonakala kwangaphandle kufana ne-square square. Ngaphakathi, itafile ehambayo ifakwe kuyo. Ifowuni ixhunyiwe kwikhompyutha kwaye ilawulwa yiyo.
Umgaqo we-CT usekelwe kwimiba eyahlukeneyo emzimbeni womntu ilahlekile i-X-ray engalinganiyo. Lezo zixhasayo, zichithe ukukhanya, zincinci - zithatha. Imiphumo iyenzeka ngexesha ngalinye leenkqubo. Izixhobo zilungisa, kwaye emva
Ngamaxesha amaninzi ukuhlolwa kwe CT kungenziwa?
Ngenxa yokuba le nkqubo ihambelana ngqo ne-ray ray ye-X, kaninzi ayinakwenziwa. Ngaphambi kokubhalwa kweemviwo, ugqirha kufuneka afunde ngekhadi yesigulane ngokubanzi kwaye afumane umthwalo wegazi owamkelayo.
Ukwenza i-computer ye-tomography, nangona umda wokungcola udlulile, kuyimfuneko kuphela kwimeko apho ingasindisa ubomi, kwaye akukho nenye indlela yokuxilonga ayikwazi ukusebenza ngexesha elifanayo.
Uhlobo oluthile lokuphuma kwimiba lunokuthi lube ngumoya we-CT, owenzela kakhulu ukunciphisa umthamo we-irradiation efunyenweyo.
