Iskena se-Arm CT

Ukuskena ngengalo okuyi-computed tomography (CT) kuyindlela yokucabanga esebenzisa ama-x-ray ukwenza izithombe ezingxenyeni ezihlukene zengalo.

Uzocelwa ukuba ulale etafuleni elincane elingena phakathi kwesithwebuli se-CT.

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

Ikhompyutha idala izithombe ezihlukene zendawo yengalo, ebizwa ngokuthi izingcezu. Lezi zithombe zingagcinwa, zibukwe kumonitha, noma ziphrintwe kwifilimu. Izinhlobo ezinokwakheka kwengalo ezintathu zingadalwa ngokungeza izingcezu ndawonye.

Kufanele uthule ngesikhathi sokuhlolwa. Ukunyakaza kungadala izithombe ezifiphalisiwe. Ungatshelwa ukuthi ubambe umoya wakho isikhathi esifushane.

Ukuskena kufanele kuthathe kuphela imizuzu eyi-10 kuye kwengu-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.
• Ngaphambi kokuthola umehluko, tshela umhlinzeki wakho uma uthatha i-metformin yesidakamizwa sikashukela (Glucophage). Ungahle udinge ukuthatha izinyathelo ezikhethekile uma ukule muthi.

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 kufundwa.

Abanye abantu bangase bangakhululeki ngokulala etafuleni eliqinile.

Umehluko onikezwe nge-IV ungadala ukuzwa okushisayo okuncane, ukunambitheka kwensimbi emlonyeni, nokushiswa komzimba okufudumele. Lokhu kuzizwa kungokwemvelo. Zizohamba phakathi nemizuzwana embalwa.

I-CT yakha ngokushesha izithombe ezinemininingwane zomzimba, kufaka phakathi izingalo. Ukuhlolwa kungasiza ukuthola noma ukuxilonga:

• Ithumba noma ukutheleleka
• Imbangela yobuhlungu noma ezinye izinkinga esihlakaleni, emahlombe noma endololwaneni (imvamisa lapho i-MRI ingenakwenziwa)
• Ithambo eliphukile
• Amasisa nezicubu, kufaka phakathi umdlavuza
• Izinkinga zokuphulukisa noma izicubu ezibomvu ngemuva kokuhlinzwa

I-CT scan nayo ingasetshenziselwa ukuhola udokotela ohlinzayo endaweni efanele ngesikhathi se-biopsy.

Imiphumela ibhekwa njengejwayelekile uma kungabonwa zinkinga ezithombeni.

Imiphumela engajwayelekile ingabangelwa:

• Izinguquko ezizenzakalelayo ngenxa yeminyaka
• Ithumba (ukuqoqwa kobomvu)
• Ukuqina kwegazi engalweni (i-venous thrombosis ejulile)
• Izimila zamathambo
• Umdlavuza
• Ithambo eliphukile noma eliphukile
• Ukulimala kwesandla, isihlakala, noma amalunga endololwana
• UCyst
• Izinkinga zokuphulukisa noma ukukhula kwezicubu ezibomvu ngemuva kokuhlinzwa

Izingozi zokuhlolwa kwe-CT zifaka:

• Ukuvezwa yimisebe
• Ukusabela okweqile ekuqhathaniseni udayi
• Ukukhubazeka kokuzalwa uma kwenziwa ngesikhathi sokukhulelwa

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 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, ungathola 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 ukuze opharetha akwazi ukukuzwa ngaso sonke isikhathi.
