I-CT angiography - isisu kunye nesinqe

I-CT angiography idibanisa i-CT scan kunye nenaliti yedayi. Obu buchule buyakwazi ukwenza imifanekiso yemithambo yegazi esiswini sakho (isisu) okanye indawo yesinqe. 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 "zokujikeleza" zinokuqhuba uviwo zingayeki.

Ikhompyuter yenza imifanekiso eyahlukileyo yendawo yesisu, ebizwa ngokuba ngamanqatha. 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.

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 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.
• Kuya kufuneka uphinde usele okwahlukileyo ngaphambi koviwo. Xa usela umahluko uya kuxhomekeka kuhlobo loviwo olwenziwe. Umahluko unencasa ekrelekrele, nangona ezinye zineencasa ukuze zingcamle ngcono. Umahluko uya kugqitha emzimbeni wakho ngezitulo zakho.
• 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-metformin (iGlucophage). Abantu abathatha eli yeza kusenokufuneka bayeke ukulithatha okwexeshana ngaphambi kovavanyo.

Umahluko unokuba nzima kwiingxaki zomsebenzi wezintso kwizigulana ezinezintso ezingasebenzi kakuhle. Thetha nomboneleli wakho ukuba unembali yeengxaki zezintso.

Ubunzima obuninzi bunokonakalisa iskena. Ukuba unobunzima obungaphezulu kweepawundi ezingama-300 (i-135 kilograms), thetha nomboneleli wakho malunga nomda wobunzima ngaphambi kovavanyo.

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

Ukulala kwitafile enzima kunokuba kukungonwabisi.

Ukuba unomahluko kumthambo, unokuba:

• Ukutshisa kancinci
• Incasa yentsimbi emlonyeni wakho
• Ukufudumeza okufudumeleyo komzimba wakho

Ezi mvakalelo ziqhelekile kwaye ziyahamba kwimizuzwana embalwa.

I-CT angiography scan ngokukhawuleza yenza imifanekiso eneenkcukacha zemithambo yegazi ngaphakathi kwesisu sakho okanye isinqe.

Olu vavanyo lunokusetyenziselwa ukukhangela:

• Ukwandiswa okungaqhelekanga okanye ibhaluni yenxalenye yomthambo (aneurysm)
• Umthombo wokopha oqala emathunjini okanye kwenye indawo esiswini okanye esinqeni
• Ubunzima kunye nezidumba esiswini okanye esinqeni, kubandakanya umhlaza, xa kufuneka uncede ukucwangcisa unyango
• Unobangela weentlungu esiswini ekucingelwa ukuba zibangelwa kukunciphisa okanye ukuvaleka kwemithambo enye okanye nangaphezulu ebonelela ngamathumbu amancinci kunye amakhulu
• Iintlungu emilenzeni ekucingelwa ukuba zibangelwa kukuncipha kwemithambo yegazi ebonelela ngemilenze neenyawo
• Uxinzelelo lwegazi oluphezulu ngenxa yokuxinana kwemithambo ehambisa igazi kwizintso

Uvavanyo lusenokusetyenziswa ngaphambili:

• Utyando kwimithambo yegazi yesibindi
• Ukutshintshwa kwezintso

Iziphumo zithathwa njengeziqhelekileyo ukuba akukho ngxaki zibonwayo.

Iziphumo ezingaqhelekanga zingabonisa:

• Umthombo wokopha ngaphakathi kwesisu okanye isinqe
• Ukucuthwa komthambo obonelela ngezintso
• Ukunciphisa imithambo ebonelela ngamathumbu
• Ukunciphisa imithambo ebonelela ngemilenze
• Ukubhaliswa okanye ukudumba kwemithambo (aneurysm), kubandakanya i-aorta
• Ukuqhawula eludongeni lwe-aorta

Iingozi ze-CT scan zibandakanya:

• Ukungezwani komzimba kuthelekisa idayi
• Ukubonakaliswa kwimitha
• Ukonakala 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. Thetha nomboneleli wakho wezempilo malunga nalo mngcipheko kunye nesibonelelo sovavanyo lokufumana ukuxilongwa ngokuchanekileyo kwengxaki yakho yonyango. Uninzi lwabavavanyi bale mihla basebenzisa iindlela zokusebenzisa imitha engaphantsi.

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 iodine emzimbeni. Unokufuna ulwelo olongezelelekileyo emva kovavanyo ukunceda ukukhupha iodine emzimbeni wakho ukuba unesifo sezintso okanye isifo seswekile.

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