I-CT ehlombe

Iskena sekhompyuter ye-tomography (CT) yamagxa yindlela yokucinga esebenzisa i-x-ray ukwenza imifanekiso enqamlezayo yegxalaba.

Uya kucelwa ukuba ulale kwitafile emxinwa ethe tyaba embindini wesikena se-CT.

Nje ukuba ngaphakathi ngaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ujikeleze wena. Izikena zale mihla "zokujika" zinokuqhuba uviwo zingayekanga.)

Ikhompyuter yenza imifanekiso eyahlukileyo yendawo egxalabeni. Ezi zibizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli ezinemilinganiselo emithathu yommandla wamagxa zinokwenziwa ngokudibanisa izilayi kunye.

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

Iskena kufuneka sithathe kuphela imizuzu eli-10 ukuya kweli-15.

Ezinye iimviwo zifuna idayi ekhethekileyo, ebizwa ngokuba ngumahluko, ukuba ihanjiswe emzimbeni ngaphambi kovavanyo. Umahluko unceda iindawo ezithile ukuba zibonise ngcono kwii-ray.

• Umahluko unokunikwa ngomthambo (IV). Ukuba kusetyenziswa umahluko, unokucelwa ukuba ungatyi okanye usele nantoni na iiyure ezi-4 ukuya kwezi-6 phambi kovavanyo.
• Yazisa umboneleli wakho wezempilo ukuba ngaba ukhe wasabela ngokuchaseneyo. Kuya kufuneka uthathe amayeza ngaphambi kovavanyo ukuze ufumane le nto ngokukhuselekileyo.
• Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile (i-Glucophage) kuba ungadinga ukuthatha amanyathelo okhuseleko.

Ukuba unobunzima obungaphezu kweepawundi ezingama-300 (135 kilograms), fumanisa ukuba umatshini we-CT unomlinganiselo wobunzima. Ubunzima obuninzi bunokubangela umonakalo kwiindawo zokusebenza zesikena.

Uya kucelwa ukuba ususe ubucwebe kwaye unxibe ilokhwe yasesibhedlele ngexesha lofundo.

Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

Umahluko onikezwe nge-IV unokubangela ukutshisa okuncinci, incasa yentsimbi emlonyeni, kunye nokufudumeza komzimba. Ezi mvakalelo ziqhelekile kwaye zihlala zihamba kwimizuzwana embalwa.

I-CT yenza ngokukhawuleza imifanekiso enegxalaba. Uvavanyo lunokunceda ukufumanisa okanye ukufumanisa:

• Ukwahlukana, ukuphuka, okanye ukulimala kwegxalaba
• Vavanya izicwili ezithambileyo ezinjengeetoni zerotator
• Ithumba okanye usulelo
• Unobangela weentlungu okanye ezinye iingxaki kumdibaniso wamagxa xa i-MRI ingenakwenziwa
• Ubunzima kunye namathumba, kubandakanya umhlaza
• Ukuphilisa iingxaki okanye izicwili ezibomvu emva kotyando

Olu vavanyo lunokukunceda ukukhokela ugqirha kwindawo elungileyo ngexesha le-biopsy kwindawo egxalabeni.

Iziphumo zithathwa njengeziqhelekileyo ukuba igxalaba elivavanywayo liqhelekile kwinkangeleko.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Ithumba (ingqokelela yobofu)
• Amathumba amathambo okanye umhlaza
• Igxalaba lisuswe
• Ukuphuka kwamagxa
• Ikhafu yerotator iyalila
• Ukusilela ekuphiliseni okanye ekuphuhliseni izicwili ezibomvu emva kotyando

Iingozi ze-CT scan zibandakanya:

• Ukuvezwa kwimitha
• Ukusabela okungahambelaniyo nokwahlula idayi
• Isiphene sokuzalwa ukuba senziwe ngexesha lokukhulelwa

Iiskrini ze-CT zikubhengeza kwimitha engaphezulu kwee-ray eziqhelekileyo. Ukuba ne-x-ray okanye i-CT scans ekuhambeni kwexesha kunokunyusa umngcipheko womhlaza. Nangona kunjalo, umngcipheko nakuphi na ukuskena okukodwa kuncinci. Wena kunye nomboneleli wakho kufuneka ulinganise lo mngcipheko ngokubhekiselele kwizibonelelo zokufumana ukuxilongwa ngokuchanekileyo kwingxaki 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 umntu one-iodine allergies unikwa olu hlobo lokwahluka, isicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye umngxunya kungenzeka.
• Ukuba ngokuqinisekileyo kufuneka unikwe umahluko, unokufuna ukufumana ii-antihistamines (ezinjengeBenadryl) okanye ii-steroids ngaphambi kovavanyo.
• Izintso zinceda ukususa iodine emzimbeni. Abo banesifo sezintso okanye isifo seswekile banokufuna ukufumana ulwelo olongezelelweyo emva kovavanyo ukunceda ukukhupha iodine emzimbeni.

Ngokuqhelekileyo, idayi inokubangela ukuba ubomi buphendule ngokusongela ubomi obubizwa ngokuba yi-anaphylaxis. Ukuba unengxaki yokuphefumla ngexesha lovavanyo, kuya kufuneka wazise umqhubi weskena kwangoko. I-Scanners ziza ne-intercom kunye nezithethi, ke umqhubi unokukuva ngamaxesha onke.
