Ukuskena kwe-CT esiswini

Iskena se-CT esiswini yindlela yokucinga. Olu vavanyo lusebenzisa i-x-ray ukwenza imifanekiso enqamlezayo yesisu. I-CT imele i-computed tomography.

Uya kulala kwitafile emxinwa ethe tyaba ingena kumbindi wesikena se-CT. Rhoqo, uya kulala ngomqolo iingalo ziphakanyiswe ngaphezu kwentloko.

Nje ukuba ngaphakathi ngaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ujikeleze wena. Izikena zangoku zokuqhuba zinokwenza uviwo ngaphandle kokuma.

Ikhompyuter yenza imifanekiso eyahlukileyo yesisu. Ezi zibizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli ezinemilinganiselo emi-ntathu yesisu zingenziwa ngokubekelela izilayi ngokudibeneyo.

Kuya kufuneka uthe cwaka ngexesha loviwo, kuba intshukumo ibangela imifanekiso emnyama. Unokuxelelwa ukuba ubambe umphefumlo wakho ixesha elifutshane.

Kwiimeko ezininzi, isisu se-CT senziwa nge-pelvis CT.

Iskena kufuneka sithathe ngaphantsi kwemizuzu engama-30.

Kufuneka ube nedayi ekhethekileyo, ebizwa ngokuba ngumahluko, ibekwe emzimbeni wakho phambi koviwo. Umahluko unceda iindawo ezithile ukuba zibonise ngcono kwii-ray. Umahluko unokulawulwa ngeendlela ezahlukeneyo. Njenge:

• Umahluko unokunikwa ngomthambo (IV) osesandleni sakho okanye kwingalo yakho. Ukuba kusetyenziswa umahluko, unokucelwa ukuba ungatyi okanye usele nantoni na iiyure ezi-4 ukuya kwezi-6 phambi kovavanyo.
• Kuya kufuneka ukuba usele umahluko ngaphambi koviwo. Xa usela kuya kuxhomekeka kuhlobo loviwo olwenziwe. Umahluko unencasa ekrelekrele, nangona ezinye zinencasa ngoko ke zingcamla ngcono. Umahluko oselayo uya kuphuma emzimbeni wakho kwisitulo sakho kwaye awunabungozi.

Yazisa umboneleli wakho wezempilo ukuba ngaba ukhe wasabela ngokuchaseneyo. Kuya kufuneka uthathe amayeza ngaphambi kovavanyo ukuze ufumane ngokukhuselekileyo le nto.

Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile metformin. Abantu abathatha eli yeza kusenokufuneka bayeke ukulithatha okwexeshana ngaphambi kovavanyo.

Yazisa umboneleli wakho ukuba unayo nayiphi na ingxaki yezintso. Umahluko we-IV unokuba mandundu ekusebenzeni kwezintso.

Ubunzima obuninzi bunokonakalisa iskena. Fumanisa ukuba umatshini we-CT unomlinganiselo wobunzima ukuba unobunzima obungaphezu kweekhilogram ezingama-135.

Kuya kufuneka ukhulule izacholo zakho kwaye unxibe ilokhwe yasesibhedlele ngexesha lofundo.

Ukulala kwitafile enzima kunokuba kukungonwabisi.

Ukuba unomahluko kumthambo (IV), unokuba:

• Ukutshisa kancinci
• I-Metallic incasa emlonyeni
• Ukufudumeza okufudumeleyo komzimba

Ezi mvakalelo ziqhelekile kwaye ziyahamba kwimizuzwana embalwa.

Iskena se-CT esiswini senza imifanekiso eneenkcukacha zezakhiwo ngaphakathi kwesisu sakho ngokukhawuleza okukhulu.

Olu vavanyo lunokusetyenziselwa ukukhangela:

• Unobangela wegazi kumchamo
• Unobangela wentlungu yesisu okanye ukudumba
• Unobangela weziphumo ezingaqhelekanga zovavanyo lwegazi ezinje ngesibindi okanye iingxaki zezintso
• UHernia
• Unobangela womkhuhlane
• Ubunzima kunye namathumba, kubandakanya umhlaza
• Usulelo okanye ukwenzakala
• Amatye eentso
• Isihlomelo

Iskena se-CT esiswini sinokubonisa ezinye i-cancer, kubandakanya:

• Umhlaza wesinqe sezintso okanye ureter
• Umhlaza wamathumbu
• I-hepatocellular carcinoma
• KwiLymphoma
• Melanoma
• Umhlaza we-Ovarian
• Umhlaza wepancreatic
• Pheochromocytoma
• I-Renal cell carcinoma (umhlaza wezintso)
• Ukusasazeka komhlaza oqale ngaphandle kwesisu

Iskena se-CT esiswini sinokubonisa iingxaki nge-gallbladder, isibindi, okanye ipancreas, kubandakanya:

• Cholecystitis Acute
• Isifo sesibindi esinxilisayo
• Cholelithiasis
• Ithumba lepancreatic
• I-pseudocyst yePancreatic
• Ipancreatitis
• Ukuvalelwa kwemibhobho yenyongo

Iskena se-CT esiswini sinokubonisa ezi ngxaki zilandelayo zezintso:

• Ukuvalwa kwezintso
• I-Hydronephrosis (ukuvuvukala kwezintso kwi-backflow yomchamo)
• Usulelo lwezintso
• Amatye eentso
• Izintso okanye umonakalo we-ureter
• Isifo sezintso sePolycystic

Iziphumo ezingaqhelekanga zinokubangelwa:

• Isisu esine-aortic aneurysm
• Amathumba
• Isihlomelo
• Ukuqina kodonga lwamathumbu
• Isifo seCrohn
• Umthambo we-renal stenosis
• I-vein vein thrombosis

Iingozi ze-CT scan zibandakanya:

• Ukungezwani komzimba kuthelekisa idayi
• Ukubonakaliswa kwimitha
• Umonakalo ekusebenzeni kwezintso kwidayi eyahlukileyo

Ukuskena kwe-CT kukuvezela imitha engaphezulu kwee-ray eziqhelekileyo. Uninzi lwe-x-ray okanye i-CT scans ngokuhamba kwexesha inokunyusa umngcipheko womhlaza. Nangona kunjalo, umngcipheko nakuphi na ukuskena okukodwa kuncinci. Uninzi lwabavavanyi bale mihla bayakwazi ukunciphisa ukubonakaliswa kwemitha. Thetha nomboneleli wakho malunga nalo mngcipheko kunye nesibonelelo sovavanyo lokufumana ukuxilongwa ngokuchanekileyo kwengxaki yakho yonyango.

Abanye abantu banesifo sokungafani nedayi. Yazisa umboneleli wakho ukuba ngaba ukhe wafumana into engahambelaniyo nokwahlula idayi.

Olona hlobo luqhelekileyo lokuthelekisa olunikezwe emthanjeni luqukethe iodine. Ukuba une-iodine ye-allergies, unokuba nesicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye imingxunya xa ufumana olu hlobo lokwahluka. Ukuba kufuneka unikwe umahluko onjalo, umboneleli wakho unokukunika ii-antihistamines (ezinjengeBenadryl) okanye ii-steroids ngaphambi kovavanyo.

Izintso zakho zinceda ukususa idayi ye-IV emzimbeni. Unokufuna ulwelo olongezelelekileyo emva kovavanyo ukunceda ukukhupha iodine emzimbeni wakho ukuba unesifo sezintso okanye isifo seswekile.

Rhoqo, idayi inokubangela ukusabela kubungozi obusongela ubomi. Xelela umqhubi weskena kwangoko ukuba unengxaki yokuphefumla ngexesha lovavanyo. I-Scanners ziza ne-intercom kunye nezithethi, ke umqhubi unokukuva ngamaxesha onke.
