I-CT scan (computed tomography) iyisivivinyo sokuthwebula izithombe esisiza abahlinzeki bezempilo ukuthola izifo nokulimala. Isebenzisa uchungechunge lwe-X-ray namakhompyutha ukudala izithombe ezinemininingwane zamathambo nezicubu ezithambile. I-CT scan ayinabuhlungu futhi ayihlaseli. Ungaya esibhedlela noma esikhungweni sokuthwebula izithombe ukuze uthole i-CT scan ngenxa yohlobo oluthile lokugula. Lesi sihloko sizokwethula ngokuningiliziwe ku-CT scan.
Kuyini i-CT scan?
Ukuskena kwe-CT (computed tomography) kuwukuhlolwa kwesithombe. Njenge-X-ray, kungabonisa izakhiwo emzimbeni wakho. Kodwa esikhundleni sokudala izithombe ezisicaba ze-2D, ukuskena kwe-CT kuthatha amashumi kuya kwamakhulu ezithombe zomzimba. Ukuze uthole lezi zithombe, i-CT izothatha ama-X-ray njengoba ijikeleza kuwe.
Abahlinzeki bezempilo basebenzisa ama-CT scan ukuze babone ukuthi yiziphi i-X-ray ezivamile ezingenakukwazi ukuzibonisa. Isibonelo, izakhiwo zomzimba ziyahlangana kuma-X-ray avamile, futhi izinto eziningi azibonakali. I-CT ibonisa ulwazi oluningiliziwe mayelana nesitho ngasinye ukuze kube nombono ocacile noqondile.
Elinye igama le-CT scan yi-CAT scan. I-CT imele “i-computed Tomography,” kanti i-CAT imele “i-computed axial tomography.” Kodwa la magama amabili achaza ukuhlolwa okufanayo kwesithombe.
I-CT scan ikhombisani?
I-CT scan ithatha izithombe zakho:
Amathambo.
Imisipha.
Izitho zomzimba.
Imithambo yegazi.
Yini engatholwa yi-CT scan?
Ukuskena kwe-CT kusiza abahlinzeki bezempilo ukuthola ukulimala nezifo ezahlukahlukene, okuhlanganisa:
Izinhlobo ezithile zomdlavuza kanye nezimila ezingenabungozi (ezingenamdlavuza).
Ukuphuka kwamathambo (amathambo aphukile).
Isifo senhliziyo.
Amahlule egazi.
Izinkinga zamathumbu (i-appendicitis, i-diverticulitis, ukuvaleka, isifo sikaCrohn).
Amatshe ezinso.
Ukulimala kobuchopho.
Ukulimala komgogodla.
Ukopha kwangaphakathi.
Ukulungiselela ukuskena kwe-ct
Nazi ezinye iziqondiso ezijwayelekile:
Hlela ukufika kusenesikhathi. Udokotela wakho uzokutshela ukuthi kufanele ugcine nini isikhathi sakho sokubonana.
Ungadli amahora amane ngaphambi kokuhlolwa kwe-CT.
Phuza kuphela uketshezi olucacile (njengamanzi, ujusi, noma itiye) emahoreni amabili ngaphambi kokuqokwa kwakho.
Gqoka izingubo ezikhululekile bese ukhumula noma yibuphi ubucwebe bensimbi noma izingubo (qaphela ukuthi noma yini equkethe insimbi ayivunyelwe!). Umhlengikazi angakunikeza ingubo yasesibhedlela.
Udokotela wakho angasebenzisa izinto ezibonisa umehluko ukuze agqamise izindawo ezithile zomzimba wakho ku-scan. Ukuze uthole i-CT scan eveza umehluko, umhlinzeki uzofaka i-IV (i-catheter efakwa emthanjeni) bese efaka i-contrast medium (noma idayi) emthanjeni wakho. Bangase bakunike nento ongayiphuza (njenge-barium swallow) ukuze iphume emathunjini akho. Kokubili kungathuthukisa ukubonakala kwezicubu ezithile, izitho noma imithambo yegazi futhi kusize abahlinzeki bezempilo ukuthi bahlole izimo ezahlukahlukene zezokwelapha. Uma uchama, izinto ezibonisa umehluko emthanjeni zivame ukukhishwa emzimbeni wakho zingakapheli amahora angama-24.
Okulandelayo ezinye iziphakamiso zokulungiselela i-CT contrast scan:
Ukuhlolwa kwegazi: Ungadinga ukuhlolwa kwegazi ngaphambi kokuskena kwakho kwe-CT okuhleliwe. Lokhu kuzosiza umhlinzeki wakho wezempilo ukuqinisekisa ukuthi i-contrast medium iphephile ukuyisebenzisa.
Imikhawulo yokudla: Kuzodingeka uqaphele ukudla kwakho emahoreni amane ngaphambi kwe-CT scan yakho. Ukuphuza uketshezi olucacile kuphela kungasiza ekuvimbeleni isicanucanu ngenkathi uthola i-contrast media. Ungaphuza umhluzi, itiye noma ikhofi emnyama, ijusi elihlungiwe, i-gelatin engenalutho, kanye neziphuzo ezibandayo ezicacile.
Imithi yokungezwani komzimba: Uma une-allergy ku-contrast medium esetshenziselwa i-CT (equkethe i-iodine), kungadingeka ukuthi uthathe ama-steroid nama-antihistamine ngobusuku bangaphambi nangemva kokuhlinzwa. Qiniseka ukuthi uthintana nomhlinzeki wakho wezempilo bese ubacela ukuthi baku-odele le mithi uma kudingeka. (Ama-contrast agent e-MRI ne-CT ahlukile. Ukuba ne-allergy ku-contrast agent eyodwa akusho ukuthi une-allergy kwenye.)
Ukulungiselela Isixazululo: Isixazululo semidiya yokubonisa umehluko womlomo kufanele sisetshenziswe njengoba nje kuqondiswe.
Imisebenzi ethile ku-CT scan
Ngesikhathi sokuhlolwa, isiguli sivame ukulala ngomhlane etafuleni (njengombhede). Uma ukuhlolwa kwesiguli kudinga lokho, umhlinzeki wezempilo angafaka idayi yokungafani ngemithambo yegazi (emthanjeni wesiguli). Idayi ingabangela iziguli ukuba zizizwe zimanzi noma zibe nokunambitheka kwensimbi emlonyeni wazo.
Uma ukuskena kuqala:
Umbhede wangena kancane kancane kwisikena. Kuleli qophelo, isimo sedonathi sidinga ukuhlala sithule ngangokunokwenzeka, njengoba ukunyakaza kuzofiphaza isithombe.
Ezifana nedonathi zingase zicelwe ukuba zibambe umoya wazo isikhashana, ngokuvamile ngaphansi kwemizuzwana eyi-15 kuya kwengama-20.
Isithwebuli sithatha isithombe esifana nedonathi sendawo okudingeka abahlinzeki bezempilo bayibone. Ngokungafani nezikena ze-MRI (izikena ze-magnetic resonance imaging), izikena ze-CT azithuli.
Ngemva kokuba ukuhlolwa sekuqediwe, ibhentshi lokusebenzela libuyela emuva ngaphandle kwesithwebuli.
Ubude besikhathi sokuskena kwe-CT
Ukuskena kwe-CT kuvame ukuthatha cishe ihora. Isikhathi esiningi kulungiselelwa. Ukuskena ngokwako kuthatha imizuzu engaphansi kweyi-10 noma eyi-15. Ungaqhubeka nemisebenzi evamile ngemva kokuba umhlinzeki wakho wezempilo evumile - ngokuvamile ngemva kokuba sebeqedile ukuskena futhi baqinisekisa ukuthi ikhwalithi yesithombe ilungile.
Imiphumela emibi ye-CT scan
I-CT scan ngokwayo ayibangeli imiphumela emibi. Kodwa abanye abantu bathola imiphumela emibi emincane evela ku-contrast agent. Le miphumela emibi ingafaka isicanucanu nokuhlanza, ikhanda elibuhlungu, kanye nesiyezi.

Mayelana ne-LnkMed:
Kusukela ekusungulweni kwayo,I-LnkMedubelokhu egxile emkhakheni weama-injector ejenti yokungafani anomfutho ophezuluIthimba lobunjiniyela le-LnkMed liholwa yi-Ph.D. elinolwazi olungaphezu kweminyaka eyishumi futhi lihileleke kakhulu ocwaningweni nasekuthuthukisweni. Ngaphansi kwesiqondiso sakhe,Umjovo wekhanda elilodwa le-CT, Umjovo wekhanda eliphindwe kabili we-CT, Umjovo we-MRI contrast agent, futhiI-Angiography high-pressure contrast agent injector injectorzenzelwe lezi zici: umzimba oqinile futhi ohlangene, isikhombimsebenzisi sokusebenza esilula nesihlakaniphile, imisebenzi ephelele, ukuphepha okuphezulu, kanye nomklamo ohlala isikhathi eside. Singaphinde sinikeze amasirinji namashubhu ahambisana nalawo mabhrendi adumile e-CT, MRI, DSA injectors Ngenxa yesimo sabo sengqondo esiqotho kanye namandla ochwepheshe, bonke abasebenzi be-LnkMed bakumema ngobuqotho ukuthi nize nizohlola izimakethe ezengeziwe ndawonye.
