Iskena seKnee

Iskena sekhompyuter (CT) sedolo luvavanyo olusebenzisa ii-ray-ray ukuthatha imifanekiso eneenkcukacha zedolo.

Uya kulala kwitafile emxinwa ethe tyaba ingena kumbindi wesikena se-CT.

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

Ikhompyuter yenza imifanekiso eliqela yendawo yomzimba. Ezi zibizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli zommandla womzimba kwi-3-D zinokwenziwa ngokudibanisa izilayi kunye.

Kuya kufuneka uhlale uzolile ngexesha loviwo, kuba intshukumo iyayifaka imifanekiso. Kuya kufuneka ubambe umphefumlo wakho ixesha elifutshane.

Iskena kufuneka sithathe ngaphantsi kwemizuzu engama-20.

Ezinye iimviwo zifuna idayi ekhethekileyo, ebizwa ngokuba ngumahluko, ukuze ifakwe ngaphakathi komzimba 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 ukunqanda le ngxaki.
• Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile i-metformin (iGlucophage). Kuya kufuneka uthathe amanyathelo ongezelelweyo ukuba uthatha eli yeza.

Ubunzima obuninzi bunokubangela umonakalo kwiindawo zokusebenza zesikena. Buza malunga nomyinge wobunzima ngaphambi kovavanyo ukuba unobunzima obungaphezu kweepawundi ezingama-300 (135 kilograms).

Kuya kufuneka ususe ubucwebe kwaye unxibe ilokhwe yasesibhedlele ngexesha loviwo lwe-CT.

Abanye abantu banokungonwabi belele phezu kwetafile elukhuni.

Umahluko onikezwe nge-IV unokubangela:

• Imvakalelo encinci yokutsha
• I-Metallic incasa emlonyeni
• Ukufudumeza okufudumeleyo komzimba

Ezi mvakalelo ziqhelekile kwaye zihlala zihamba ngemizuzwana embalwa.

Iskena se-CT singenza ngokukhawuleza imifanekiso eneedolo kunee-x-reyi eziqhelekileyo. Uvavanyo lunokusetyenziselwa ukufumanisa:

• Ithumba okanye usulelo
• Ithambo elaphukileyo
• Vavanya ukwaphuka kunye nepateni yokwahlukana
• Unobangela wentlungu okanye ezinye iingxaki emadolweni ngokudibeneyo (ngesiqhelo xa iMRI ingenakwenziwa)
• 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 akukho ngxaki zibonwayo.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Ithumba (ingqokelela yobofu)
• Isifo samathambo
• Ithambo elaphukileyo
• Amathumba amathambo okanye umhlaza
• Ukuphilisa iingxaki okanye izicwili ezibomvu emva kotyando

Iingozi ze-CT scan zibandakanya:

• Ukubonakaliswa kwimitha
• Ukungezwani komzimba kuthelekisa idayi
• Isiphene sokuzalwa ukuba senziwe ngexesha lokukhulelwa

Ukuskena kwe-CT kunika 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. Wena nomboneleli wakho kufuneka nixoxe ngomngcipheko xa kuthelekiswa nexabiso lokuchongwa ngokuchanekileyo kwengxaki.

Yazisa umboneleli wakho ukuba ngaba ukhe wafumana into engahambelaniyo nokwahlula idayi.

• Olona hlobo luqhelekileyo lokuthelekisa luqukethe iodine. Unokuba nesicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye umngxunya ukuba unale iodine allergies.
• Ukuba ufuna olu hlobo lokwahluka, unokufuna ii-antihistamines (ezinjengeBenadryl) okanye ii-steroids ngaphambi kovavanyo.
• Izintso zinceda ukususa iodine emzimbeni. Unokufuna ulwelo olongezelelekileyo emva kovavanyo ukunceda ukususa umzimba wakho kwi-iodine ukuba unesifo sezintso okanye isifo seswekile.

Ngokuqhelekileyo, idayi inokubangela ukuphendula kakubi okubizwa ngokuba yi-anaphylaxis. Oku kungasongela ubomi. Yazisa umvavanyi kwangoko ukuba unengxaki yokuphefumla ngexesha lovavanyo. I-Scanners ine-intercom kunye nezithethi ukuze umqhubi akwazi ukukuva ngalo lonke ixesha.
