Ukuskena kwentliziyo kwe-CT

Iskena sekhompyuter se-tomography (CT) sentliziyo yindlela yokucinga esebenzisa i-x-reyi ukwenza imifanekiso eneenkcukacha zentliziyo kunye nemithambo yegazi.

• Olu vavanyo lubizwa ngokuba yi-coronary calcium scan xa lwenziwe ukubona ukuba unayo i-calcium ekwimithambo yentliziyo yakho.
• Ibizwa ngokuba yi-CT angiography ukuba kuyenziwa ukujonga imithambo ezisa igazi entliziyweni yakho. Olu vavanyo luvavanya ukuba kukho ukuncipha okanye ukubhloka kwezo methambo.
• Uvavanyo ngamanye amaxesha lwenziwa ngokudityaniswa nokuskena i-aorta okanye imithambo yemiphunga ukujonga iingxaki kwezo zakhiwo.

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

• Uya kulala ngomqolo kunye nentloko kunye neenyawo ngaphandle kwesikena esiphelweni.
• Amabala amancinci, abizwa ngokuba zii-electrode abekwa esifubeni sakho kwaye aqhagamshelwe kumatshini orekhoda umsebenzi wombane wentliziyo yakho. Unokunikwa iyeza lokunciphisa ukubetha kwentliziyo yakho.
• Nje ukuba ngaphakathi ngaphakathi kwiskena, umqadi we-x-ray umatshini ujikeleza ujikeleze wena.

Ikhompyuter yenza imifanekiso eyahlukileyo yommandla womzimba, obizwa ngokuba zizilayi.

• Le mifanekiso inokugcinwa, ijongwe esweni, okanye iprintwe kwifilimu.
• I-3D (ntathu-ntathu) iimodeli zentliziyo zinokwenziwa.

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

Iskena siphela kufuneka sithathe kuphela malunga nemizuzu eli-10.

Ezinye iimviwo zifuna idayi ekhethekileyo, ebizwa ngokuba ngumahluko, ukuba ihanjiswe emzimbeni ngaphambi 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.

Ngaphambi kokufumana umahluko:

• Yazisa umboneleli wakho wezempilo ukuba ukhe wasabela ngokuchaseneyo okanye nawaphi na amayeza. Kuya kufuneka uthathe amayeza ngaphambi kovavanyo ukuze ufumane le nto ngokukhuselekileyo.
• Xelela umboneleli wakho ngawo onke amayeza akho, kuba unokucelwa ukuba ubambe amanye, njengeyeza leswekile i-metformin (iGlucophage), phambi kovavanyo.
• Yazisa umboneleli wakho ukuba uneengxaki zezintso. Izinto ezichaseneyo zinokubangela ukuba umsebenzi wezintso ube mandundu.

Ukuba unobunzima obungaphezu kweepawundi ezingama-300 (135 kilograms), fumanisa ukuba umatshini we-CT unomlinganiselo wobunzima. Ubunzima obuninzi bunokubangela umonakalo kwiindawo zokusebenza zesikena.

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

Abanye abantu banokungonwabi ngokulala etafileni elukhuni.

Umahluko onikezwe nge-IV unokubangela:

• Ukutshisa kancinci
• I-Metallic incasa emlonyeni
• Ukufudumeza okufudumeleyo komzimba

Ezi mvakalelo ziqhelekile kwaye zihlala zihamba ngemizuzwana embalwa.

I-CT yakha ngokukhawuleza imifanekiso eneenkcukacha zentliziyo kunye nemithambo yayo. Uvavanyo lunokufumanisa okanye lubhaqe:

• Ukwakhiwa kweplaque kwimithambo yegazi ukumisela umngcipheko wesifo sentliziyo
• Isifo sentliziyo esibelekweni (iingxaki zentliziyo ezikhoyo ekuzalweni)
• Iingxaki ngezivalo zentliziyo
• Ukuvaleka kwemithambo ebonelela ngentliziyo
• Amathumba okanye ubunzima bentliziyo
• Umsebenzi wokumpompa kwentliziyo

Iziphumo zithathwa njengeziqhelekileyo ukuba intliziyo kunye nemithambo evavanyiweyo iqhelekile ngenkangeleko.

"Amanqaku akho e-calcium" asekwe kwinani lecalcium efumaneka kwimithambo yentliziyo yakho.

• Uvavanyo luqhelekile (lubi) ukuba amanqaku akho e-calcium ayi-0. Oku kuthetha ukuba ithuba lokuhlaselwa sisifo sentliziyo kwiminyaka eliqela elandelayo liphantsi kakhulu.
• Ukuba amanqaku e-calcium asezantsi kakhulu, akunakulindeleka ukuba ubenesifo semithambo.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Unyango
• Isifo sentliziyo
• Imithambo yegazi
• Iingxaki zevalvu zentliziyo
• Ukudumba kokugquma okungqonge intliziyo (pericarditis)
• Ukunciphisa enye okanye ngaphezulu kwemithambo yegazi (i-coronary artery stenosis)
• Izidumba okanye olunye uhlobo lwentliziyo okanye indawo eziyingqongileyo

Ukuba amanqaku akho e-calcium aphezulu:

• Kuthetha ukuba unokwakhiwa kwecalcium kwiindonga zemithambo yakho yemithambo. Oku kuhlala kungumqondiso we-atherosclerosis, okanye ukuqina kwemithambo.
• Ukunyuka kwamanqaku akho, kokukhona le ngxaki inokuba mandundu.
• Thetha nomboneleli wakho malunga notshintsho lwendlela onokuyenza ukunciphisa umngcipheko wesifo sentliziyo.

Umngcipheko wokuvavanywa kwe-CT ubandakanya:

• Ukuvezwa kwimitha
• Ukusabela okungahambelaniyo nokwahlula idayi

Iiskrini ze-CT zikubhengeza kwimitha 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.

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 umntu one-iodine allergies unikwa olu hlobo lokwahluka, isicaphucaphu okanye ukugabha, ukuthimla, ukurhawuzelela, okanye umngxunya kungenzeka.
• Ukuba ngokuqinisekileyo kufuneka unikwe umahluko onjalo, kusenokufuneka uthathe ii-steroids (ezinje nge-prednisone) okanye ii-antihistamines (ezinje nge-diphenhydramine) ngaphambi kovavanyo. Kuya kufuneka uthathe i-histamine blocker (enjenge-ranitidine).
• Izintso zinceda ukususa iodine emzimbeni. Abo banesifo 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. Ukuba unengxaki yokuphefumla ngexesha lovavanyo, kuya kufuneka wazise umqhubi weskena kwangoko. I-Scanners ziza ne-intercom kunye nezithethi, ke umqhubi unokukuva ngamaxesha onke.
