Ukuskena umlenze kwi-CT

Iskena sekhompyuter (CT) somlenze senza imifanekiso enqamlezileyo yomlenze. Isebenzisa i-x-ray ukwenza imifanekiso.

Uya kulala kwitafile emxinwa ethe tyaba ingena kumbindi 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 yommandla womzimba, obizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli ezithathu-ntathu (3D) zomlenze zinokwenziwa ngokudibanisa izilayi kunye.

Uya kudinga ukuxoka nangoku uviwo. Ukuhamba kunokubangela imifanekiso ephosakeleyo. Kuya kufuneka ubambe umphefumlo wakho ixesha elifutshane.

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

Ezinye iimviwo zisebenzisa idayi ekhethekileyo, ebizwa ngokuba ngumahluko, efakwa emzimbeni wakho phambi kovavanyo. Umahluko unceda iindawo ezithile ukuba zibonise ngcono kwii-ray.

• 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.
• Yazisa umboneleli wakho wezempilo ukuba ngaba ukhe wasabela ngokuchaseneyo. Kuya kufuneka uthathe amayeza phambi kovavanyo ukunqanda le ngxaki.
• Ngaphambi kokuba wenze umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile i-metformin (iGlucophage). Kuya kufuneka uthathe amanyathelo ongezelelweyo ngaphambi kovavanyo ukuba uthatha eli chiza.

Ubunzima obuninzi bunokubangela umonakalo kwiindawo zokusebenza zesikena. Fumanisa ukuba umatshini we-CT unomlinganiselo wobunzima ukuba unobunzima obungaphezulu kweepawundi ezingama-300 (iikhilogram ezili-135).

Uya kunxiba ilokhwe yasesibhedlele ngexesha lofundo. Kuya kufuneka ukhulule bonke ubucwebe.

Abanye abantu banokungonwabi belele phezu kwetafile elukhuni.

Umahluko onikezwe nge-IV unokubangela ukutsha okutsha, incasa yentsimbi emlonyeni, kunye nokugungxula okufudumeleyo komzimba. Ezi mvakalelo ziqhelekile kwaye ziyahamba ngemizuzwana embalwa.

I-CT scan yenza imifanekiso eneenkcukacha zomzimba ngokukhawuleza okukhulu. Uvavanyo lunokunceda ukujonga:

• Ithumba okanye usulelo
• Ubunzima obuvakalayo ngexesha lovavanyo lomzimba
• Unobangela wentlungu okanye ezinye iingxaki ezinyaweni, emaqatheni, okanye emadolweni (ngesiqhelo xa iMRI ingenakwenziwa)
• Ithambo elaphukileyo
• Umzekelo wezaphuka
• Ubunzima kunye namathumba, kubandakanya umhlaza
• Ukuphilisa iingxaki okanye izicwili ezibomvu emva kotyando

Iskena se-CT sinokusetyenziselwa ukukhokela ugqirha kwindawo elungileyo ngexesha le-biopsy.

Iziphumo zithathwa njengeziqhelekileyo ukuba umlenze ovavanywayo ujongeka ulungile.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Utshintsho olwenzakalayo ngenxa yobudala
• Ithumba okanye usulelo
• Igazi elixineneyo emlenzeni (i-venous thrombosis)
• Ithambo elaphukileyo okanye elaphukileyo
• Umhlaza
• Ukonakala kwedolo, unyawo, okanye iqatha
• Ithumba elingenamhlaza
• Ukuphilisa iingxaki okanye ukukhula kwezihlunu ezibomvu emva kotyando

Umngcipheko wokuvavanywa kwe-CT ubandakanya:

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

Ukuskena kwe-CT kukuvezela imitha engaphezulu kwee-ray eziqhelekileyo. Ukuba ne-x-reyi ezininzi okanye ii-CT scan ngokuhamba kwexesha kunokuphakamisa umngcipheko womhlaza, kodwa umngcipheko nakweyiphi na yokuskena incinci. Thetha nomboneleli wakho malunga nalo mngcipheko ngokuchasene nezibonelelo zovavanyo.

Abanye abantu banesifo sokungafani nedayi. Yazisa umboneleli wakho ukuba ukhe waba nalo olu hlobo lokuphendula.

• Olona hlobo luqhelekileyo lokuthelekisa olunikezwe emthanjeni luqukethe iodine. Umntu one-iodine allergies unokuba nesicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye umngxunya kolu luhlu lokwahluka.
• Ukuba unolu hlobo lokwahluka, unokufumana ii-antihistamines (ezinjengeBenadryl) okanye ii-steroids ngaphambi kovavanyo.
• Izintso zinceda ukususa iodine emzimbeni. Abantu abanesifo sezintso okanye isifo seswekile banokufuna ukufumana ulwelo olongezelelweyo emva kovavanyo ukunceda ukukhupha iodine emzimbeni.

Idayi inokubangela ukuba ubomi busongele impendulo ebizwa ngokuba yi-anaphylaxis. Oku kunqabile. Xelela umqhubi weskena kwangoko ukuba unengxaki yokuphefumla ngexesha lovavanyo. I-Scanners ziza ne-intercom kunye nezithethi, ke umqhubi unokukuva ngamaxesha onke.
