Ukuqinisekisa ukuxilongwa, imishini ye-CT yesimanje ivame ukusetshenziswa - ikhompyutha ye-tomography. Ngenxa yalokhu, izithombe ezilayishiwe zesakhiwo sangaphakathi sezitho ezinebanga lika-3-5 mm ziyatholakala.
Iyini i-CT yezinso?
Ukuhlolwa kwe-hardware kungasetshenziswa ngesikhathi sokuhlola okujwayelekile. Kodwa kaningi kunconywa ukusola ngezinkinga ezilandelayo:
- ukuhlukunyezwa izinso;
- ukungabikho kokuzalwa kwangasese;
- izinqubo ezithathelwanayo ezinomsebenzi ongasebenzi kahle;
- ukutholakala kwamatshe ;
- i-oncology.
Njenganoma yiluphi uhlobo lwezinkinga ze-hardware, i-CT iyathuthukiswa kancane kancane. Uma izithombe zangaphambili zamukelwe ngendlela yezithombe ezihlukene, manje i-tomograph yokuvunguza ivumela ukuthi ingahlukanisi isendlalelo sesithombe ngendlala. Ngaphezu kwalokho, ukusungulwa kwedivaysi ye-multispiral kwenza kube lula ukuhlola isayithi elithile lesiguli ngemizuzwana embalwa nje.
Ukulungiselela i-CT yezinso
I-CT yezinso noma ngaphandle kokungafani, ayidingi noma yiziphi izinyathelo ezikhethekile zokulungiselela. Isimo kuphela akumele udle amahora amathathu ngokushesha ngaphambi kokuhlolwa.
Uma kwenzeka ukusebenzisa umbala wokugqoka, isiguli kufanele simemezele udokotela uma i-allergenic i-iodine noma izilwane zasolwandle. Lokhu kudingekile mayelana nobungozi bokuziphendulela okubangelwa ukwelashwa okungahle kwenzeke njengomphumela we-CT wezinso ngokuphambene, ngoba i-iodine isetshenziswa kaningi njengezinto ezimibalabala.
I-kidney CT?
Inqubo ngokwayo ilula kakhulu:
- Isiguli kufanele size ukuhlolwa ngezingubo ezingavimbeli ukunyakaza. Uma kungenjalo, kufanele uphazamise.
- Emzimbeni akufanele kube khona izinto zensimbi, kuhlanganise namacici, ukubhoboza - lezi zinto zizophazamisa isithombe.
- Uma usebenzisa ukungafani, into ejojowe nge-injection ekhethiwe ngokuzenzakalelayo. Uma umjovo awukwazi ukuthathwa, umuthi uphathwa ngomlomo.
- Konke okudingekayo kwesiguli ukulala etafuleni elisendlini ye-tomograph bese uhlala ngesikhathi sokuhlolwa.
- Nakuba udokotela ophethe isithwebuli esesigumbini esilandelayo, uhlale eqapha ukuqapha ngokuqapha.
- Kudingekile ukuba ulandele imiyalelo kadokotela ngokucacile, isibonelo, ukubamba umoya ngokuyalela.
Ubude bezinso ezijwayelekile ze-kidney CT zingama-5-10 amaminithi. Uma usebenzisa umehluko, qala ukuthatha izithombe ngaphandle kombala bese ujova umuthi. Ngakho-ke, inqubo iphinda iphindwe kabili futhi isikhathi sokuhlola senyuke sibe imizuzu engu-25.
