Yini i-computed tomography, yenzelwa ini futhi yenziwa kanjani?
-Delile
I-computed tomography, noma i-CT, ukuhlolwa kwesithombe okusebenzisa ama-X-ray ukukhiqiza izithombe zomzimba ezicutshungulwa yikhompyutha, okungaba ngamathambo, izitho noma izicubu. Lokhu kuhlolwa akububangeli ubuhlungu futhi noma ngubani angabenza, kepha-ke, abesifazane abakhulelwe kufanele benze ezinye izivivinyo njengenye indlela yokwenza i-computed tomography, efana ne-ultrasound noma i-resonance kazibuthe, njengoba ukuvezwa ngemisebe kukhulu kutamatography.
I-Tomography ingenziwa ngokusebenzisa noma ngaphandle kokuqhathanisa, okuwuhlobo loketshezi olungagwinywa, lufakwe emthanjeni noma lufakwe ku-rectum ngesikhathi sokuhlolwa ukwenza lula ukubonwa kwezitho ezithile zomzimba.
Intengo ye-computed tomography iyahluka phakathi kuka-R $ 200 kanye no-R $ 700.00, kepha lokhu kuhlolwa kuyatholakala kwa-SUS, ngaphandle kwenkokhiso. I-computed tomography kufanele yenziwe kuphela ngaphansi kokuholwa ngudokotela, ngoba ifaka ukuvezwa yimisebe, engaba yingozi empilweni uma ungenaso isiqondisi esanele.
Umshini we-computed tomography
Yenzelwe ini
I-computed tomography isetshenziselwa ukusiza ukuxilonga izifo zemisipha namathambo, ukukhomba indawo yesimila, ukutheleleka noma ihlwili, ngaphezu kokuthola nokuqapha izifo nokulimala. Izinhlobo eziyinhloko zokuhlolwa kwe-CT yilezi:
- Ukhakhayi lwesigebhezi: Kuboniswe ukuphenywa kwezinhlekelele, izifo, ukopha, i-hydrocephalus noma ama-aneurysms. Funda kabanzi ngalokhu kuhlolwa;
- I-Tomography yesisu ne-pelvis: Kucelwe ukuhlola ukuvela kwamathumba namathumba, ngaphezu kokubheka ukuthi kwenzekani nge-appendicitis, i-lithiasis, ukungasebenzi kahle kwezinso, i-pancreatitis, i-pseudocysts, ukulimala kwesibindi, i-cirrhosis ne-hemangioma.
- I-Tomography yamalungu aphezulu nangaphansi: Isetshenziselwa ukulimala kwemisipha, ukuphuka, izicubu kanye nokutheleleka;
- I-chest tomography: Kuboniswe ukuphenywa kwezifo, izifo zemithambo yegazi, ukulandelwa kwesimila nokuhlolwa kokuvela kwesimila.
Imvamisa, ukuskena kwe-CT kogebhezi, isifuba nesisu kwenziwa ngokungafani ukuze kube nokubonakala okungcono kwezakhiwo futhi kungenzeka ukuhlukanisa kalula izinhlobo ezahlukahlukene zezicubu.
I-computed tomography ngokuvamile akuyona inketho yokuqala yokuhlolwa kokuxilongwa, ngoba imisebe isetshenziselwa ukukhiqiza izithombe. Izikhathi eziningi udokotela ancoma zona, kuya ngendawo yomzimba, ezinye izivivinyo ezifana ne-X-ray, ngokwesibonelo.
Ungasilungiselela kanjani isivivinyo
Ngaphambi kokuba kwenziwe i-tomography, kubalulekile ukuzila ukudla ngokuyalelwa ngudokotela, okungaba amahora amane kuya kwayisithupha, ukuze umehluko ungene kahle. Ngaphezu kwalokho, kubalulekile ukumisa ukusetshenziswa kwe-metformin yesidakamizwa, uma isetshenzisiwe, amahora angama-24 ngaphambi kanye namahora angama-48 ngemuva kokuhlolwa, njengoba kungahle kube nokusabela ngokuqhathanisa.
Ngesikhathi sokuhlolwa umuntu ulele phezu kwetafula bese engena kuhlobo lomhubhe, i-tomograph, imizuzu eyi-15. Lokhu kuhlolwa akulimazi futhi akubangeli ukucindezeleka, njengoba imishini ivulwa.
Izinzuzo nobubi be-CT
I-computed tomography isivivinyo esisetshenziswa kabanzi ukusiza ekutholeni izifo eziningana ngoba kuvumela ukuhlolwa kwezingxenye (izingxenye) zomzimba, ukuhlinzeka ngezithombe ezibukhali nokukhuthaza ukuhlukaniswa kwezicubu ezahlukahlukene. Ngoba kungukuhlolwa okuguquguqukayo, i-CT ibhekwa njengesivivinyo sokuzikhethela ekuphenyweni kwamaqhuqhuva obuchopho noma amaphaphu noma izicubu.
Ububi be-CT iqiniso lokuthi ukuhlolwa kwenziwa ngokukhishwa kwemisebe, i-X-ray, okuthi noma ingekho ngobuningi bayo, ingaba nemiphumela emibi empilweni lapho umuntu ehlale evezwa yilolu hlobo wemisebe. Ngaphezu kwalokho, ngokuya ngenhloso yokuhlolwa, udokotela angancoma ukuthi kungasetshenziswa umehluko, okungaba nezingozi ezithile ngokuya ngomuntu, njengokuphendula komzimba kanye nemiphumela enobuthi emzimbeni. Bona ukuthi iziphi izingozi ezingaba khona zezivivinyo ngokuqhathanisa.
