Iskena se-CT
Iskena se-computed tomography (CT) siyindlela yokucabanga esebenzisa ama-x-ray ukwenza izithombe zezingxenye ezihamba emzimbeni.
Ukuhlolwa okuhlobene kufaka phakathi:
- Isisu nesisu se-CT scan
- I-Cranial noma ikhanda le-CT scan
- Umlomo wesibeletho, i-thoracic, ne-lumbosacral spine CT scan
- Iskena se-Orbit CT
- Isikena se-CT esifubeni
Uzocelwa ukuba ulale etafuleni elincane elingena phakathi kwesithwebuli se-CT.
Uma usungaphakathi kwesithwebuli, ugongolo lomshini lwe-x-ray luzungeza eduze kwakho. Izikena zesimanje zokuvunguza zingenza isivivinyo ngaphandle kokuma.
Ikhompyutha idala izithombe ezihlukene zendawo yomzimba, ezibizwa ngokuthi izingcezu. Lezi zithombe zingagcinwa, zibukwe kumonitha, noma zikopishelwe kudiski. Amamodeli amathathu-ntathu endawo yomzimba angakhiwa ngokufaka izingcezu ndawonye.
Kufanele uhlale unganyakazi ngesikhathi sokuhlolwa, ngoba ukunyakaza kubangela izithombe ezifiphalisiwe. Ungatshelwa ukuthi ubambe umoya wakho isikhathi esifushane.
Ukuqedela ukuskena kuvame ukuthatha imizuzu embalwa kuphela. Ama-scanner amasha angenza isithombe somzimba wakho wonke ngaphansi kwemizuzwana engama-30.
Izivivinyo ezithile zidinga udayi okhethekile, obizwa ngokuqhathanisa, ukulethwa emzimbeni wakho ngaphambi kokuqala kokuhlolwa. Umehluko usiza izindawo ezithile ukuthi zibonakale kangcono kuma-x-ray.
Yazisa umhlinzeki wakho wezokunakekelwa kwempilo uma ngabe uke waba nokusabela kokungafani. Ungadinga ukuthi uphuze imithi ngaphambi kokuhlolwa ukuze ugweme okunye ukusabela.
Umehluko unganikezwa ngezindlela eziningana, kuya ngohlobo lwe-CT olwenziwa.
- Ingalethwa ngomthambo (IV) osesandleni sakho noma engalweni.
- Ungahle uphuze umehluko ngaphambi kokuskena kwakho. Uma uphuza umehluko uxhomeke ohlotsheni lokuhlolwa okwenziwayo. Uketshezi olwehlukanisayo lunganambitheka luchalk, yize amanye enongiwe. Umehluko uphuma emzimbeni wakho ngezitulo zakho.
- Imvamisa, umehluko unganikezwa ku-rectum yakho usebenzisa i-enema.
Uma kusetshenziswa umehluko, ungacelwa futhi ukuthi ungadli noma uphuze noma yini amahora amane kuya kwayisithupha ngaphambi kokuhlolwa.
Ngaphambi kokuthola umehluko we-IV, tshela umhlinzeki wakho uma uthatha umuthi wesifo sikashukela i-metformin (Glucophage). Abantu abathatha lo muthi kungadingeka ukuthi bayeke okwesikhashana. Futhi yazisa umhlinzeki wakho uma unezinkinga ngezinso zakho. Umehluko we-IV ungonakalisa ukusebenza kwezinso.
Thola ukuthi ngabe umshini we-CT unomkhawulo wesisindo uma unesisindo esingaphezu kwamakhilogremu angama-135 (135 kilograms). Isisindo esiningi kakhulu singalimaza isithwebuli.
Uzodinga ukususa ubucwebe futhi ugqoke ingubo ngesikhathi kufundwa.
Abanye abantu bangase bangakhululeki ngokulala etafuleni eliqinile.
Umehluko onikezwe nge-IV ungadala umuzwa ovuthayo omncane, ukunambitheka kwensimbi emlonyeni, nokushiswa komzimba okufudumele. Le mizwa ijwayelekile futhi imane ihambe ngemizuzwana embalwa.
I-CT scan idala izithombe ezinemininingwane zomzimba, kufaka phakathi ubuchopho, isifuba, umgogodla nesisu. Isivivinyo singasetshenziselwa uku:
- Thola isifo
- Qondisa udokotela endaweni efanele ngesikhathi se-biopsy
- Thola izixuku nezicubu, kufaka phakathi umdlavuza
- Fundisisa imithambo yegazi
Imiphumela ibhekwa njengejwayelekile uma izitho nezinhlaka ezihloliswayo zibukeka ngendlela ejwayelekile.
Imiphumela engajwayelekile incike engxenyeni yomzimba efundwayo. Khuluma nomhlinzeki wakho ngemibuzo nokukhathazeka.
Izingozi zokuba nezikena ze-CT zifaka:
- Ukusabela okwe-allergen kudayi wokuqhathanisa
- Ukulimala kokusebenza kwezinso kusuka kudayi wokuqhathanisa
- Ukuvezwa yimisebe
Ukuskena kwe-CT kukuvezela imisebe engaphezulu kwama-x-ray avamile. Ukuba nama-x-ray amaningi noma ama-CT scan ngokuhamba kwesikhathi kungakhuphula ingozi yokuba nomdlavuza. Noma kunjalo, ingozi evela kunoma yikuphi ukuskena okukodwa incane. Wena nodokotela wakho kufanele nilinganise le ngozi ngokubaluleka kolwazi oluzotholakala ku-CT scan. Imishini eminingi emisha ye-CT scan inamandla okunciphisa umthamo wemisebe.
Abanye abantu banokungezwani komzimba nokuqhathanisa udayi. Yazisa umhlinzeki wakho uma ngabe uke waba nokungezwani komzimba nodayi wokuqhathanisa ojojowe.
- Uhlobo oluvame kakhulu lokungafani olunikezwe emthanjeni luqukethe iodine. Uma une-iodine yokungezwani komzimba, umehluko ungadala isicanucanu noma ukuhlanza, ukuthimula, ukulunywa noma isifuba.
- Uma kufanele unikezwe umehluko onjalo, udokotela wakho angakunika ama-antihistamine (njengeBenadryl) noma ama-steroids ngaphambi kokuhlolwa.
- Izinso zakho zisiza ukususa iodine emzimbeni. Ungadinga ukuthola uketshezi olwengeziwe ngemuva kokuhlolwa ukusiza ukukhipha iodine emzimbeni wakho uma unesifo sikashukela noma isifo sezinso.
Imvamisa, idayi ingadala ukusabela okweqile okusongela impilo okubizwa nge-anaphylaxis. Uma unenkinga yokuphefumula ngesikhathi sokuhlolwa, tshela opharetha wesithwebuli ngokushesha. Ama-scanner eza ne-intercom nezipikha, ngakho-ke opharetha angakuzwa ngaso sonke isikhathi.
