I-CT angiography - iingalo kunye nemilenze

I-CT angiography idibanisa i-CT scan kunye nenaliti yedayi. Obu buchule buyakwazi ukwenza imifanekiso yemithambo yegazi engalweni okanye emilenzeni. I-CT imele i-computed tomography.

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

Xa ungaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ujikeleze wena. Izikena zangoku "zokujikeleza" zinokuqhuba uviwo zingayeki.

Ikhompyuter yenza imifanekiso emininzi yendawo yomzimba, ebizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli zommandla womzimba kubukhulu obuthathu zinokwenziwa ngokudibanisa izilayi kunye.

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

Ukuskena kufuneka kuthathe kuphela malunga nemizuzu emi-5.

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) osesandleni sakho okanye kwingalo yakho. Ukuba umahluko usetyenzisiwe, 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.

Umahluko unokubangela iingxaki zeengxaki zezintso kubantu abanezintso ezingasebenzi kakuhle. Thetha nomboneleli wakho ukuba unembali yeengxaki zezintso.

Ubunzima obuninzi bunokubangela umonakalo kwiindawo zokusebenza zesikena. Ukuba unobunzima obungaphezulu kweepawundi ezingama-300 (i-135 kilograms), thetha nogqirha wakho malunga nomyinge wobunzima ngaphambi kovavanyo.

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
• Incasa yentsimbi emlonyeni wakho
• Ukufudumeza okufudumeleyo komzimba wakho

Ezi mvakalelo ziqhelekile kwaye zihlala zihamba ngemizuzwana embalwa.

Unokulufuna olu vavanyo ukuba uneempawu zethambo legazi elincinci okanye elivalekileyo kwiingalo, izandla, imilenze, okanye iinyawo.

Uvavanyo luyakwenziwa ukufumanisa ukuba:

• Ukwandiswa okungaqhelekanga okanye ibhaluni yenxalenye yomthambo (aneurysm)
• Ukopha
• Ukudumba okanye ukudumba kwemithambo yegazi (vasculitis)
• Intlungu yomlenze ngexesha lokuhamba okanye lokuzilolonga (ukucacisa)

Iziphumo zithathwa njengeziqhelekileyo ukuba akukho ngxaki zibonwayo.

Isiphumo esingaqhelekanga siqhele ukwenzeka ngenxa yokunciphisa kunye nokuqina kwemithambo engalweni okanye emilenzeni evela kulwakhiwo lweplaka kwiindonga zemithambo.

IX-reyi ingabonisa ukuvaleka kwiinqanawa ezibangelwa:

• Ukwandiswa okungaqhelekanga okanye ibhaluni yenxalenye yomthambo (aneurysm)
• Amahlwili egazi
• Ezinye izifo zemithambo

Iziphumo ezingaqhelekanga zinokubangelwa:

• Ukudumba kwemithambo yegazi
• Ukwenzakala kwimithambo yegazi
• Isifo seBugerger (thromboangiitis obliterans), isifo esinqabileyo apho imithambo yegazi yezandla neenyawo ivaliwe
  

Iingozi ze-CT scan zibandakanya:

• Ukubonakaliswa kwimitha
• Ukungezwani komzimba kuthelekisa idayi
• Umonakalo kwizintso ezivela kwidayi eyahlukileyo

Ukuskena kwe-CT kunika imitha 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 nomboneleli wakho kufuneka nixoxe ngomngcipheko xa kuthelekiswa nexabiso lokuchongwa ngokuchanekileyo kwengxaki. Uninzi lwabavavanyi bale mihla basebenzisa iindlela zokusebenzisa imitha engaphantsi.

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

• Olona hlobo luqhelekileyo lokuthelekisa luqukethe iodine. Ukuba une-iodine ye-allergies, unokuba nesicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye imingxunya xa ufumana olu hlobo lokwahluka.
• Ukuba ufuna olu hlobo lokwahluka, umboneleli wakho unokukunika 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.
