Iskena se-CT esiswini

Iskena se-CT esiswini siyindlela yokuthwebula. Lokhu kuhlolwa kusebenzisa ama-x-ray ukudala izithombe ezihlukanisayo zesisu. I-CT imele i-computed tomography.

Uzolala etafuleni elincane elingena phakathi kwesithwebuli se-CT. Imvamisa, uzolala ngomhlane izingalo zakho ziphakanyiswe ngaphezu kwekhanda lakho.

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

Ikhompyutha idala izithombe ezihlukile zendawo yesisu. Lokhu kubizwa ngokuthi izingcezu. Lezi zithombe zingagcinwa, zibukwe kumonitha, noma ziphrintwe kwifilimu. Izinhlobo ezinamacala amathathu wesisu zingenziwa ngokufaka izingcezu ndawonye.

Kufanele uthule ngesikhathi sokuhlolwa, ngoba ukunyakaza kubangela izithombe ezifiphalisiwe. Ungatshelwa ukuthi ubambe umoya wakho isikhathi esifushane.

Ezimweni eziningi, i-CT yesisu yenziwa nge-pelvis CT.

Iskena kufanele sithathe ngaphansi kwemizuzu engama-30.

Udinga ukuba nedayi ekhethekile, ebizwa ngokuqhathanisa, efakwe emzimbeni wakho ngaphambi kokuhlolwa okuthile. Umehluko usiza izindawo ezithile ukuthi zibonakale kangcono kuma-x-ray. Ukuqhathanisa kungalawulwa ngezindlela ezahlukahlukene. Njenge:

• 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.
• Kungadingeka uphuze umehluko ngaphambi kokuhlolwa. Uma uphuza kuzoya ngohlobo lokuhlolwa okwenziwayo. Umehluko unokunambitheka okunechalky, yize amanye enongiwe ngakho anambitha kangcono kancane. Umehluko owuphuzayo uzodlula emzimbeni wakho ungene ezitokisini zakho futhi awunabungozi.

Yazisa umhlinzeki wakho wezokunakekelwa kwempilo uma ngabe uke waba nokusabela kokungafani. Ungahle udinge ukuthatha imithi ngaphambi kokuhlolwa ukuze uthole le nto ngokuphepha.

Ngaphambi kokuthola umehluko, tshela umhlinzeki wakho uma uthatha umuthi wesifo sikashukela i-metformin. Abantu abathatha lo muthi kungadingeka bayeke ukuwuthatha isikhashana ngaphambi kokuhlolwa.

Yazisa umhlinzeki wakho uma unezinkinga zezinso. Umehluko we-IV ungonakalisa ukusebenza kwezinso.

Isisindo esiningi kakhulu singalimaza isithwebuli. Thola ukuthi ngabe umshini we-CT unomkhawulo wesisindo uma unesisindo esingaphezu kwamakhilogremu angama-135.

Uzodinga ukukhumula ubucwebe bakho bese ugqoka ingubo yasesibhedlela ngesikhathi kufundwa.

Ukulala etafuleni elinzima kungahle kungakhululeki kancane.

Uma uqhathanisa nge-vein (IV), ungahle ube:

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

Le mizwa ijwayelekile futhi iyaphela ngemizuzwana embalwa.

Iskena se-CT esiswini senza izithombe eziningiliziwe zezakhiwo ngaphakathi esiswini sakho ngokushesha okukhulu.

Lokhu kuhlolwa kungasetshenziselwa ukubheka:

• Imbangela yegazi emchameni
• Imbangela yobuhlungu besisu noma ukuvuvukala
• Imbangela yemiphumela yokuhlolwa kwegazi engajwayelekile enjengezinkinga zesibindi noma zezinso
• Hernia
• Imbangela yomkhuhlane
• Amasisa nezicubu, kufaka phakathi umdlavuza
• Ukutheleleka noma ukulimala
• Amatshe ezinso
• Isithasiselo

Ukuskena kwe-CT esiswini kungakhombisa amanye umdlavuza, kufaka phakathi:

• Umdlavuza we-renal pelvis noma i-ureter
• Umdlavuza wamakholoni
• I-hepatocellular carcinoma
• I-Lymphoma
• I-Melanoma
• Umdlavuza we-Ovarian
• Umdlavuza wepancreatic
• Pheochromocytoma
• I-Renal cell carcinoma (umdlavuza wezinso)
• Ukusabalala komdlavuza oqale ngaphandle kwesisu

Ukuskena kwe-CT esiswini kungakhombisa izinkinga nge-gallbladder, isibindi noma amanyikwe, kufaka phakathi:

• I-cholecystitis enamandla
• Isifo sesibindi esidakayo
• I-Cholelithiasis
• Ithumba lepancreatic
• I-pseudocyst yePancreatic
• I-Pancreatitis
• Ukuvinjelwa kwamapayipi enyongo

Ukuskena kwe-CT esiswini kungaveza lezi zinkinga zezinso ezilandelayo:

• Ukuvinjelwa kwezinso
• I-Hydronephrosis (ukuvuvukala kwezinso kusuka ekuphumeni komchamo)
• Ukutheleleka kwezinso
• Amatshe ezinso
• Ukulimala kwezinso noma kwe-ureter
• Isifo sezinso sePolycystic

Imiphumela engajwayelekile futhi ingabangelwa:

• I-aneurysm yesisu esiswini
• Amathumba
• Isithasiselo
• Ukuqina kodonga lwamathumbu
• Isifo seCrohn
• I-renal artery stenosis
• I-vein vein thrombosis

Izingozi zokuhlolwa kwe-CT zifaka:

• Ukungezwani komzimba nokuqhathanisa udayi
• Ukuvezwa yimisebe
• Ukulimala kokusebenza kwezinso kusuka kudayi wokuqhathanisa

Ukuskena kwe-CT kukuvezela imisebe engaphezulu kwama-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. Izikena eziningi zesimanje ziyakwazi ukunciphisa ukuvezwa ngemisebe. Khuluma nomhlinzeki wakho ngale ngozi kanye nenzuzo yesivivinyo sokuthola ukuxilongwa okulungile kwenkinga yakho 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. Uma une-iodine yokungezwani komzimba, ungahle ube nesicanucanu noma uhlanze, uthimule, ulume, noma isifuba uma uthola lolu hlobo lokungafani. Uma kufanele unikezwe umehluko onjalo, umhlinzeki wakho angakunika ama-antihistamine (njengeBenadryl) noma ama-steroids ngaphambi kokuhlolwa.

Izinso zakho zisiza ukususa udayi we-IV emzimbeni. Ungadinga uketshezi olungeziwe ngemuva kokuhlolwa ukusiza ukukhipha iodine emzimbeni wakho uma unesifo sezinso noma isifo sikashukela.

Imvamisa, udayi ungadala ukusabela okweqile okusongela impilo. Tshela opharetha wesithwebuli khona manjalo uma unenkinga yokuphefumula ngesikhathi sokuhlolwa. Ama-scanner eza ne-intercom nezipikha, ngakho-ke opharetha angakuzwa ngaso sonke isikhathi.
