Ukuskena komlenze CT

Ukuskena komlenze okwenziwe ngekhompuyutha (CT) kwenza izithombe ezinqamulelayo zomlenze. Isebenzisa ama-x-ray ukudala izithombe.

Uzolala 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 yomzimba, ezibizwa ngokuthi izingcezu. Lezi zithombe zingagcinwa, zibukwe kumonitha, noma ziphrintwe kwifilimu. Izinhlobo zemilenze emithathu (i-3D) yomlenze zingakhiwa ngokungeza izingcezu ndawonye.

Uzodinga ukulala unganyakazi ngesikhathi sokuhlolwa. Ukunyakaza kungadala izithombe ezifiphalisiwe. Ungadinga ukubamba umoya wakho isikhathi esifushane.

Ukuskena kufanele kuthathe kuphela imizuzu eyi-10 kuye kwengu-15.

Ezinye izivivinyo zisebenzisa udayi okhethekile, obizwa ngokuthi ukungafani, ofakwa emzimbeni wakho ngaphambi kokuqala 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 ugweme le nkinga.
• Ngaphambi kokuthola umehluko, tshela umhlinzeki wakho uma uthatha umuthi wesifo sikashukela i-metformin (Glucophage). Ungadinga ukuthatha izinyathelo ezingeziwe ngaphambi kokuhlolwa uma uthatha lo muthi.

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

Uzogqoka ingubo yasesibhedlela ngesikhathi kufundwa. Uzodinga ukususa konke ubucwebe.

Abanye abantu bangakhululeka belele etafuleni elinzima.

Umehluko onikezwe nge-IV ungadala umuzwa ovuthayo omncane, ukunambitheka kwensimbi emlonyeni, nokushaywa komzimba okufudumele. Le mizwa ijwayelekile futhi iyahamba ngemizuzwana embalwa.

I-CT scan yenza izithombe ezinemininingwane zomzimba ngokushesha okukhulu. Ukuhlolwa kungasiza ukubheka:

• Ithumba noma ukutheleleka
• Ubunzima obuzwakala ngesikhathi sokuhlolwa komzimba
• Imbangela yobuhlungu noma ezinye izinkinga ezinyaweni, eqakaleni, noma emadolweni (imvamisa lapho i-MRI ingenakwenziwa)
• Ithambo eliphukile
• Iphethini yokuhlukana
• 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 umlenze ohlolwayo ubukeka ulungile.

Imiphumela engajwayelekile ingabangelwa:

• Izinguquko ezizenzakalelayo ngenxa yeminyaka
• Ithumba noma ukutheleleka
• Ukuqina kwegazi emlenzeni (i-venous thrombosis)
• Ithambo eliphukile noma eliphukile
• Umdlavuza
• Ukulimala kwamadolo, unyawo, noma iqatha
• Isimila samathambo esingenaso umdlavuza
• 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 yomdlavuza, kepha ingozi evela kunoma yikuphi ukuskena okukodwa incane. Khuluma nomhlinzeki wakho mayelana nale ngozi ngokumelene nezinzuzo zokuhlolwa.

Abanye abantu banokungezwani komzimba nokuqhathanisa udayi. Yazisa umhlinzeki wakho uma ngabe uke waba nalolu hlobo lokuphendula.

• Uhlobo oluvame kakhulu lokungafani olunikezwe emthanjeni luqukethe iodine. Umuntu onenkinga yokungezwani komzimba ne-iodine angaba nesicanucanu noma ukuhlanza, ukuthimula, ukulunywa noma isifuba ngalolu hlobo lokuqhathanisa.
• Uma kufanele ube nalolu hlobo lokuqhathanisa, ungathola ama-antihistamine (njengeBenadryl) noma ama-steroids ngaphambi kokuhlolwa.
• Izinso zisiza ukususa i-iodine emzimbeni. Abantu abanesifo sezinso noma isifo sikashukela bangadinga ukuthola uketshezi oluthe xaxa ngemuva kokuhlolwa ukusiza ukukhipha iodine emzimbeni.

Idayi ingadala impendulo esongela impilo yokungezwani komzimba ebizwa nge-anaphylaxis. Lokhu akuvamile. Tshela opharetha wesithwebuli khona manjalo uma unenkinga yokuphefumula ngesikhathi sokuhlolwa. Ama-scanner eza ne-intercom nezipikha, ngakho-ke opharetha angakuzwa ngaso sonke isikhathi.
