Iskena se-CT

I-computed tomography (CT) scan yamadolo isivivinyo esisebenzisa ama-x-ray ukuthatha izithombe eziningiliziwe zamadolo.

Uzolala etafuleni elincane elingena phakathi kwesithwebuli se-CT.

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

Ikhompyutha yenza izithombe eziningana zendawo yomzimba. Lokhu kubizwa ngokuthi izingcezu. Lezi zithombe zingagcinwa, zibukwe kumonitha, noma ziphrintwe kwifilimu. Amamodeli endawo yomzimba ku-3-D angakhiwa ngokungeza izingcezu ndawonye.

Kufanele uhlale unganyakazi ngesikhathi sokuhlolwa, ngoba ukunyakaza kufiphaza izithombe. Kungadingeka ubambe umoya wakho isikhathi esifushane.

Iskena kufanele sithathe ngaphansi kwemizuzu engama-20.

Ezinye izivivinyo zidinga udayi okhethekile, obizwa ngokungafani, ukuze ujovwe emzimbeni wakho ngaphambi kokuhlolwa. Umehluko usiza izindawo ezithile ukuthi zibonakale kangcono kuma-x-ray.

• Umehluko unganikezwa ngomthambo (IV). 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 uma uthatha lo muthi.

Isisindo esiningi kakhulu singadala umonakalo ezingxenyeni zokusebenza zesithwebuli. Buza ngomkhawulo wesisindo ngaphambi kokuhlolwa uma unesisindo esingaphezu kwamakhilogremu angama-300 (135 kilograms).

Uzodinga ukususa ubucwebe futhi ugqoke ingubo yasesibhedlela ngesikhathi sokuhlolwa kwe-CT.

Abanye abantu bangakhululeka belele etafuleni elinzima.

Umehluko onikezwe nge-IV ungadala:

• Umuzwa ovuthayo omncane
• Ukunambitheka kwensimbi emlonyeni
• Ukushiswa komzimba okufudumele

Le mizwa ijwayelekile futhi imane iphele ngemizuzwana embalwa.

Ukuskena kwe-CT kungadala ngokushesha izithombe ezinemininingwane yamadolo kune-x-ray ejwayelekile. Ukuhlola kungasetshenziselwa ukuthola:

• Ithumba noma ukutheleleka
• Ithambo eliphukile
• Hlola ukuqhekeka nephethini yokuhlukana
• Isizathu sobuhlungu noma ezinye izinkinga emadolweni (ngokuvamile lapho i-MRI ingenakwenziwa)
• 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.

Imiphumela engajwayelekile ingabangelwa:

• Ithumba (ukuqoqwa kobomvu)
• Isifo samathambo
• Ithambo eliphukile
• Izicubu zamathambo noma umdlavuza
• Izinkinga zokuphulukisa noma izicubu ezibomvu ngemuva kokuhlinzwa

Izingozi zokuhlolwa kwe-CT zifaka:

• Ukuvezwa yimisebe
• Ukungezwani komzimba nokuqhathanisa udayi
• Ukukhubazeka kokuzalwa uma kwenziwa ngesikhathi sokukhulelwa

Izikena ze-CT zikhipha imisebe eminingi kunama-x-ray avamile. Ama-x-ray amaningi noma ama-CT scan ngokuhamba kwesikhathi kungandisa ingozi yomdlavuza. Noma kunjalo, ingozi evela kunoma yikuphi ukuskena okukodwa incane. Wena nomhlinzeki wakho kufanele nixoxe ngale ngozi uma kuqhathaniswa nenani lokuxilongwa okunembile kwenkinga.

Yazisa umhlinzeki wakho uma ngabe uke waba nokungezwani komzimba nodayi wokuqhathanisa ojojowe.

• Uhlobo oluvame kakhulu lokungafani luqukethe iodine. Ungaba nesicanucanu noma uhlanze, uthimule, ulume, noma isifuba uma unalesi sifo se-iodine.
• Uma udinga ukuba nalolu hlobo lokuqhathanisa, ungahle udinge ama-antihistamine (afana neBenadryl) noma ama-steroids ngaphambi kokuhlolwa.
• Izinso zisiza ukususa i-iodine emzimbeni. Ungadinga uketshezi olungeziwe ngemuva kokuhlolwa ukusiza ukususa umzimba wakho iodine uma unesifo sezinso noma isifo sikashukela.

Ngokuvamile, idayi ingabangela impendulo engathí sina yokungezwani komzimba ebizwa ngokuthi i-anaphylaxis. Lokhu kungasongela impilo. Yazisa opharetha besithwebuli ngokushesha uma unenkinga yokuphefumula ngesikhathi sokuhlolwa. Ama-scanner ane-intercom nezipikha ukuze opharetha akwazi ukukuzwa ngaso sonke isikhathi.
