I-CT angiography-intloko nentamo

I-CT angiography (i-CTA) idibanisa i-CT scan kunye nenaliti yedayi. I-CT imele i-computed tomography. Obu buchule buyakwazi ukwenza imifanekiso yemithambo yegazi entloko nasentanyeni.

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

Ngelixa ungaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ngeenxa zonke kuwe.

Ikhompyuter yenza imifanekiso emininzi eyahlukeneyo yendawo yomzimba, ebizwa ngokuba zizilayi. Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu. Iimodeli ezinemilinganiselo emithathu yentloko nentamo zinokwenziwa ngokudibanisa izilayi ngokudibeneyo.

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

Ukugqitywa kokugqitywa ngokuqhelekileyo kuthatha imizuzwana embalwa. Izikena ezintsha zinokufanekisela umzimba wakho uphela, intloko neenzwane, kwimizuzwana engaphantsi kwama-30.

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

• 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. Kusenokufuneka ukuba uthathe amayeza phambi kovavanyo ukuze uwafumane ngokukhuselekileyo.
• Ngaphambi kokufumana umahluko, xelela umboneleli wakho ukuba uthatha iyeza leswekile i-metformin (iGlucophage). Kuya kufuneka uthathe amanyathelo okhuseleko.

Umahluko unokubangela iingxaki zeengxaki zezintso kubantu abanezintso 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.

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

Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

Ukuba unomahluko kumthambo, unokuba:

• Imvakalelo encinci yokutsha
• Incasa yentsimbi emlonyeni wakho
• Ukufudumeza okufudumeleyo komzimba wakho

Oku kuqhelekile kwaye kuhlala kuhamba kwimizuzwana embalwa.

I-CTA yentloko inokwenziwa ukujonga unobangela woku:

• Utshintsho kwindlela ocinga ngayo okanye ekuziphatheni
• Kunzima ukubiza amagama
• Isiyezi okanye i-vertigo
• Umbono kabini okanye ukulahleka kombono
• Ukufa isiqaqa
• Intloko ebuhlungu, xa uneminye imiqondiso okanye iimpawu ezithile
• Ukuva ilahleko (kwabanye abantu)
• Ukuba ndindisholo okanye ukurhawuzelela, amaxesha amaninzi ebusweni okanye entlonzeni
• Ukuginya iingxaki
• Ukubetha
• Ukuhlaselwa kweschemic okwethutyana (TIA)
• Ubuthathaka kwilungu elinye lomzimba wakho

I-CTA yentamo inokwenziwa kwakhona:

• Emva koxinzelelo entanyeni ukujonga ukonakala kwimithambo yegazi
• Ukucwangcisela ngaphambi kotyando lweartery carotid
• Ukucwangcisa utyando lobuchopho
• Ngokukrokrela i-vasculitis (ukudumba kweendonga zemithambo yegazi)
• Ukurhanelwa kwemithambo yegazi engaqhelekanga kwingqondo

Iziphumo zithathwa njengeziqhelekileyo ukuba akukho ngxaki zibonwayo.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Imithambo yegazi engaqhelekanga (malteriovenous malformation).
• Ukopha ebuchotsheni (umzekelo, i-hematoma yangaphantsi okanye indawo yokopha).
• Ithumba lobuchopho okanye olunye ukukhula (ubunzima).
• Ukubetha.
• Imithambo emxinwa okanye evaliweyo yecarotid. (Imithambo ye-carotid ibonelela ngegazi eliphambili kwingqondo yakho. Zibekwe kwicala ngalinye lentamo yakho.)
• Umthambo omncinci okanye ovaliweyo wentambo entanyeni. (Imithambo ye-vertebral ibonelela ngokuhamba kwegazi ngasemva kwengqondo.)
• Inyembezi eludongeni lweartery (dissection).
• Indawo ebuthathaka eludongeni lomthambo wegazi obangela ukuba umthambo wegazi uphume okanye ibhaluni iphume (aneurysm).

Umngcipheko wokuvavanywa kwe-CT ubandakanya:

• Ukuvezwa kwimitha
• Ukusabela okungahambelaniyo nedayi eyahlukileyo
• Umonakalo kwizintso kwidayi

Izikena ze-CT zisebenzisa 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 kunye nomboneleli wakho kufuneka ulinganise lo mngcipheko ngokubhekiselele kwizibonelelo zokufumana ukuxilongwa ngokuchanekileyo kwingxaki 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 ngokuqinisekileyo kufuneka unikwe umahluko, umboneleli wakho unokukunika 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.

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.

Ukuvavanywa kwe-CT kunganciphisa okanye kuthintele isidingo senkqubo yokungenelela yokufumanisa iingxaki kukhakhayi. Le yenye yeendlela ezikhuselekileyo zokufunda intloko nentamo.

Olunye uvavanyo olunokwenziwa endaweni ye-CT scan entloko lubandakanya:

• I-MRI yentloko
• Ukuskena i-Positron emission tomography (PET) yentloko
