Isinema CT scan

Iskena sekhompiyutha se-tomography (CT) sesono isivivinyo sokusebenzisa izithombe esisebenzisa ama-x-ray ukwenza izithombe eziningiliziwe zezikhala ezigcwaliswe umoya ngaphakathi kobuso (amasinusi).

Uzocelwa ukuba ulale etafuleni elincane elingena phakathi kwesithwebuli se-CT. Ungahle ulale ngomhlane, noma ulale ubheke phansi ukhombe isilevu.

Uma usungaphakathi kwesithwebuli, ugongolo lomshini lwe-x-ray luzungeza eduze kwakho. Ngeke ubone umsebe we-x-ray ojikelezayo. Izikena zesimanje "ezivunguza" zingenza isivivinyo ngaphandle kokuma.)

Ikhompyutha idala izithombe ezihlukile zendawo yomzimba. Lokhu kubizwa ngokuthi izingcezu. Izithombe zingagcinwa, zibukwe kumonitha, noma ziphrintwe kwifilimu. Amamodeli amathathu-ntathu endawo yomzimba angakhiwa ngokufaka izingcezu ndawonye.

Udinga ukuhlala uthule ngesikhathi sokuhlolwa, ngoba ukunyakaza kubangela izithombe ezifiphalisiwe. Ungatshelwa ukuthi ubambe umoya wakho isikhathi esifushane. Imichilo nemicamelo kungasetshenziswa ukukugcina unganyakazi ngesikhathi senqubo.

Iskena sangempela kufanele sithathe cishe imizuzwana engama-30. Yonke inqubo kufanele ithathe imizuzu eyi-15.

Kokunye ukuhlolwa, uzodinga ukuba nedayi ekhethekile, ebizwa ngokuqhathanisa, ukuze unikezwe emzimbeni ngaphambi kokuhlolwa. Umehluko usiza izindawo ezithile ukuthi zibonakale kangcono kuma-x-ray.

• Umehluko unganikezwa ngomthambo (IV) osesandleni sakho noma engalweni. Uma kusetshenziswa umehluko, ungacelwa futhi ukuthi ungadli noma uphuze noma yini amahora amane kuya kwayisithupha ngaphambi kokuhlolwa.
• Yazisa umhlinzeki wakho wezokunakekelwa kwempilo uma ngabe uke waba nokusabela kokungafani. Ungadinga ukuthatha imithi ngaphambi kokuhlolwa ukuze uthole le nto ngokuphepha.
• Yazisa umhlinzeki wakho uma unezinkinga zezinso. Umahluko kungenzeka ungasetshenziswa uma kunjalo.
• Ngaphambi kokuthola umehluko, tshela umhlinzeki wakho uma uthatha umuthi wesifo sikashukela i-metformin (Glucophage). Ungadinga ukuthi uthathe izinyathelo ezengeziwe ukulungiselela.

Uma unesisindo esingaphezu kwamakhilogremu angama-135 (135 kilograms), thola ukuthi umshini we-CT unomkhawulo wesisindo. Isisindo esiningi kakhulu singadala umonakalo ezingxenyeni zokusebenza zesithwebuli.

Uzocelwa ukuthi ususe ubucwebe futhi ugqoke ingubo yasesibhedlela ngesikhathi sokuskena.

Abanye abantu bangase bangakhululeki ngokulala etafuleni eliqinile.

Umehluko onikezwe nge-IV ungadala:

• Ukuzwa okushisa kancane
• Ukunambitheka kwensimbi emlonyeni
• Ukushiswa komzimba okufudumele

Le mizwa ijwayelekile. Zizohamba phakathi nemizuzwana embalwa.

I-CT idala ngokushesha izithombe ezinemininingwane yezono. Isivivinyo singahlola noma sithole:

• Ukukhubazeka kokuzalwa kuma-sinus
• Ukutheleleka emathanjeni ezono (i-osteomyelitis)
• Ukulimala ebusweni ngenxa yezono ezivela ekuhlukumezeni
• Amasisa nezicubu, kufaka phakathi umdlavuza
• Polyp acinene
• Imbangela yekhala eliphindaphindeka elinegazi (epistaxis)
• Ukutheleleka kweSinus (sinusitis)

Imiphumela evela kulokhu kuhlolwa ingasiza futhi umhlinzeki wakho ukuhlela ukuhlinzwa nge-sinus.

Imiphumela ibhekwa njengejwayelekile uma kungekho nkinga ebonwa ezonweni.

Imiphumela engajwayelekile ingabangelwa:

• Izinkinga zokuzalwa
• Ukuqhekeka kwamathambo
• Umdlavuza
• Ama-polyps ezinsweni
• Ukutheleleka kweSinus (sinusitis)

Izingozi zokuthwebula i-CT zifaka:

• Ukuvezwa yimisebe
• Ukusabela okweqile ekuqhathaniseni udayi

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 kakhulu. Wena nomhlinzeki wakho kufanele nilinganise le ngozi ngezinzuzo zokuthola ukuxilongwa okulungile kwenkinga yezokwelapha.

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. Umuntu onenkinga yokungezwani komzimba ne-iodine angaba nesicanucanu noma ukuhlanza, ukuthimula, ukulunywa noma isifuba uma enikezwa lolu hlobo lokungafani.
• Uma kudingeka umehluko, unganikezwa ama-antihistamine (njengeBenadryl) noma ama-steroids ngaphambi kokuhlolwa.
• Izinso zisiza ukususa i-iodine emzimbeni. Labo abanezifo zezinso noma isifo sikashukela kungadingeka bathole uketshezi oluthe xaxa ngemuva kokuhlolwa ukusiza ukukhipha iodine emzimbeni.

Imvamisa, idayi ingadala ukusabela okweqile okusongela impilo okubizwa nge-anaphylaxis. Uma unenkinga yokuphefumula ngesikhathi sokuhlolwa, yazisa opharetha wesithwebuli azi ngokushesha. Ama-scanner ane-intercom nezipikha, ngakho-ke opharetha angakuzwa ngaso sonke isikhathi.
