I-CT (i-computed tomography) ukuhlolwa kwesithombe esiza abahlinzeki bezempilo ukuthi babone izifo nokulimala. Isebenzisa uchungechunge lwama-X-ray namakhompyutha ukuze idale izithombe ezinemininingwane yamathambo nezicubu ezithambile. Ama-CT scan awabuhlungu futhi awahlaseli. Ungaya esibhedlela noma esikhungweni sokuthwebula izithombe ukuze uthole i-CT scan ngenxa yohlobo oluthile lokugula. Lesi sihloko sizokwethula ukuskena kwe-CT ngokuningiliziwe.
Iyini i-CT scan?
Iskena se-CT (computed tomography) siwukuhlolwa kwesithombe. Njenge-X-ray, ingabonisa izakhiwo emzimbeni wakho. Kodwa esikhundleni sokwenza izithombe eziyisicaba ze-2D, ama-CT scan athatha inqwaba kuya kumakhulu ezithombe zomzimba. Ukuze uthole lezi zithombe, i-CT izothatha ama-X-ray njengoba izungeza wena.
Abahlinzeki bezempilo basebenzisa izikena ze-CT ukuze babone ukuthi yini ama-X-ray evamile angakwazi ukuyibonisa. Isibonelo, izakhiwo zomzimba zidlulela kuma-X-ray evamile, futhi izinto eziningi azibonakali. I-CT ibonisa ulwazi oluningiliziwe mayelana nesitho ngasinye ukuze uthole ukubuka okucacile, okunembe kakhudlwana.
Elinye igama le-CT scan i-CAT scan. I-CT imele “i-computed Tomography,” kuyilapho i-CAT imele “i-computed axial tomography.” Kodwa amagama amabili achaza ukuhlolwa kwe-imaging efanayo.
I-CT scan ibonisani?
I-CT scan ithatha izithombe zakho:
Amathambo.
Imisipha.
Izitho.
Imithambo yegazi.
Yini engatholwa ama-CT scan?
Ama-CT scan asiza abahlinzeki bezempilo ukuthi babone ukulimala nezifo ezahlukahlukene, kufaka phakathi:
Izinhlobo ezithile zomdlavuza kanye nezimila eziyingozi (ezingezona umdlavuza).
Ukuphuka (amathambo aphukile).
Isifo senhliziyo.
Amahlule egazi.
Ukuphazamiseka kwamathumbu (appendicitis, diverticulitis, blockages, isifo sikaCrohn).
Amatshe ezinso.
Ukulimala ebuchosheni.
Ukulimala komgogodla.
Ukopha kwangaphakathi.
Ukulungiselela i-ct scan
Nayi eminye imihlahlandlela ejwayelekile:
l Hlela ukufika kusenesikhathi. Udokotela wakho uzokutshela ukuthi uyigcine nini i-aphoyintimenti yakho.
l Ungadli amahora amane ngaphambi kwe-CT scan yakho.
l Phuza uketshezi oluhlanzekile kuphela (njengamanzi, ijusi, noma itiye) emahoreni amabili ngaphambi kokubonana kwakho.
l Gqoka izingubo ezikhululekile futhi ukhiphe noma yibuphi ubucwebe bensimbi noma izingubo (qaphela ukuthi noma yini equkethe insimbi ayivunyelwe!). Umhlengikazi angase anikeze ingubo yasesibhedlela.
Udokotela wakho angase asebenzise okuhlukile ukuze agqamise izindawo ezithile zomzimba wakho esikeni. Ukuze uthole i-CT scan ehlukile, opharetha uzobeka i-IV (i-intravenous catheter) futhi ajove indlela ehlukile (noma idayi) emthanjeni wakho. Bangase futhi bakunikeze into ephuzwayo (njenge-barium swallow) ukuze iphumele ngaphandle kwamathumbu akho. Kokubili kungathuthukisa ukubonakala kwezicubu ezithile, izitho noma imithambo yegazi futhi kusize abahlinzeki bezokunakekelwa kwempilo ukuthi bahlonze izimo ezihlukahlukene zezokwelapha. Uma uchama, okokungafani okufakwe emthanjeni kuvame ukugudluzwa ohlelweni lwakho phakathi kwamahora angama-24.
Okulandelayo ezinye iziphakamiso zokulungiselela ezengeziwe zeskena sokungafani se-CT:
Ukuhlolwa kwegazi: Ungase udinge ukuhlolwa kwegazi ngaphambi kwe-CT scan yakho ehleliwe. Lokhu kuzosiza umhlinzeki wakho wokunakekelwa kwezempilo aqinisekise ukuthi indlela yokuqhathanisa iphephile ukuyisebenzisa.
Imikhawulo yokudla: Uzodinga ukubuka ukudla kwakho amahora amane ngaphambi kwe-CT scan yakho. Ukuphuza uketshezi olucacile kuphela kungasiza ekuvimbeleni isicanucanu ngenkathi uthola imidiya yokuqhathanisa. Ungaba nomhluzi, itiye noma ikhofi elimnyama, ijusi ehlungiwe, i-gelatin engenalutho, neziphuzo ezithambile ezicacile.
Imithi yokungezwani komzimba nezinto ezithile: Uma ungezwani nesilinganiso sokuqhathanisa esisetshenziselwa i-CT (equkethe i-iodine), ungase udinge ukuthatha ama-steroid nama-antihistamine ngobusuku bangaphambi nasekuseni bokuhlinzwa. Qiniseka ukuthi uthintana nomhlinzeki wakho wokunakekelwa kwezempilo futhi umcele ukuthi aku-odele le mithi uma kudingeka. (Izinto zokuqhathanisa ze-MRI ne-CT zihlukile. Ukungezwani ne-ejenti yokuqhathanisa eyodwa akusho ukuthi awuzwani nenye.)
Ukulungiselela Isixazululo: Isixazululo semidiya yokugqama ngomlomo kufanele sidliwe njengoba kushiwo.
Imisebenzi ethile ku-CT scan
Ngesikhathi sokuhlolwa, isiguli ngokuvamile siyolala ngomhlane etafuleni (njengombhede). Uma ukuhlolwa kwesiguli kukudinga, umhlinzeki wezokunakekelwa kwempilo angase ajove udayi ohlukile emthanjeni (emthanjeni wesiguli). Udayi ungabangela iziguli ukuthi zizwe ushibilikile noma zibe nokunambitha okusansimbi emlonyeni wazo.
Uma ukuskena kuqala:
Umbhede uhambe kancane ungene kusithwebuli. Kuleli qophelo, umumo we-donut udinga ukuhlala uthule ngangokunokwenzeka, njengoba ukunyakaza kuzofiphalisa isithombe.
Ezimise okwedonathi nazo zingacelwa ukuthi zibambe umoya isikhashana, ngokuvamile zibe ngaphansi kwamasekhondi angu-15 kuya kwangu-20.
Isithwebuli sithatha isithombe esimise okwedonathi sendawo okudingeka abahlinzeki bezempilo bayibone. Ngokungafani nezikena ze-MRI (izikena ze-magnetic resonance imaging), izikena ze-CT zithule.
Ngemuva kokuthi ukuhlola sekuqediwe, ibhentshi libuyela emuva ngaphandle kwesikena.
CT scan ubude
I-CT scan ngokuvamile ithatha cishe ihora. Isikhathi esiningi ukulungiselela. Ukuskena ngokwako kuthatha ngaphansi kwemizuzu eyi-10 noma eyi-15. Ungaqalisa kabusha imisebenzi evamile ngemva kokuba umhlinzeki wakho wokunakekelwa kwezempilo evumile - ngokuvamile ngemva kokuba sebeqedile ukuskena futhi baqinisekise ukuthi ikhwalithi yesithombe yinhle.
CT scan side effects
I-CT scan ngokwayo ngokuvamile ayibangeli imiphumela emibi. Kodwa abanye abantu baba nemiphumela engemihle evela ejentini yokuqhathanisa. Le miphumela engemihle ingase ihlanganise isicanucanu nokuhlanza, ikhanda elibuhlungu, nesiyezi.

Mayelana ne-LnkMed:
Selokhu yasungulwa,I-LnkMedubelokhu egxile emkhakheni weama-ejenti wokugqama kwengcindezi ephezulu. Ithimba lonjiniyela be-LnkMed liholwa yi-Ph.D. unolwazi olungaphezu kweminyaka eyishumi futhi ubambe iqhaza ngokujulile ocwaningweni nasekuthuthukisweni. Ngaphansi kokuqondisa kwakhe, iCT umjovo wekhanda elilodwa, I-CT double head injector, Umjovo we-ejenti yokuqhathanisa ye-MRI, futhiUmjovo we-angiography wokucindezela okuphezulu kokungafaniaklanywe ngalezi zici: umzimba oqinile futhi ohlangene, isixhumi esibonakalayo esisebenzayo nesihlakaniphile, imisebenzi ephelele, ukuphepha okuphezulu, kanye nomklamo oqinile. Futhi singahlinzeka ngamasirinji namashubhu ahambisana nalezo zinhlobo ezidumile zamajovo e-CT,MRI,DSA Ngesimo sabo sengqondo esiqotho namandla ochwepheshe, bonke abasebenzi be-LnkMed bakumema ngobuqotho ukuthi nize nizohlola izimakethe ezengeziwe ndawonye.
