Ake sifunde konke mayelana ne-cardiac CT scan ngendlela elula.

Wake waya kudokotela ngoba uzwa ubuhlungu esifubeni noma ukuphelelwa umoya futhi bakutshele ukuthi wenze i-CT scan yenhliziyo yakho? Kungenzeka ukuthi wesaba kancane futhi wazibuza ukuthi kuyini, kwenziwa kanjani, nokuthi kuzobuhlungu yini. Ungakhathazeki, namuhla sizoxoxa nge-CT scan yenhliziyo yakho, noma i-Cardiac CT scan, ngendlela elula kakhulu. Lokhu ukuhlolwa okunikeza udokotela wakho ulwazi oluningi olubalulekile mayelana nempilo yenhliziyo yakho, futhi akuyona into okufanele uyesabe.

Kuyini ukuhlolwa kwenhliziyo nge-CT?

Kalula nje, lokhu ukuhlolwa kwe-X-ray okukhethekile okuthatha isithombe senhliziyo yakho esinobukhulu obuthathu (3D). Kufana nokuthatha izithombe eziningi ezicacile zenhliziyo yakho, imithambo yegazi emikhulu exhuma kuyo, nezinto ezizungezile konke ngesikhathi esisodwa.

Lokhu kuhilela ukuthumela imisebe eminingana ye-X-ray emzimbeni wakho kusuka kuma-engeli ahlukene nokuhlanganisa idatha nekhompyutha ukudala isithombe se-3D esicacile kakhulu nesinemininingwane. Ngezinye izikhathi, ukuze lezi zithombe zicace nakakhulu, uketshezi olukhethekile olubizwa ngokuthi idayi yokungafani lufakwa emthanjeni osengalweni yakho. Lolu ketshezi lwenza imithambo yegazi yakho nezingxenye zenhliziyo yakho zivelele kangcono ekuskeni. Le ndlela ingaveza izithombe ezicacile kakhulu, ezisezingeni eliphezulu, ngisho nezenhliziyo yakho eshayayo.

Yini ngempela le scan engayithola?

Izithombe ezitholwe ngemuva kwalokhu kuskena zizovumela udokotela wakho ukuthi abone izinto eziningi ngenhliziyo yakho. Eziyinhloko yilezi:

• Imithambo yegazi yenhliziyo, enikeza igazi enhliziyweni yakho: Le mithambo yegazi ingahlolwa ukuthi ayinayo yini i-plaque, ukuvaleka, noma ukuncipha.
• Amakamelo enhliziyo, imisipha namavalvu: Ubukhulu bamakamelo enhliziyo, ukusebenza kwemisipha, nokuthi amavalvu asebenza kahle yini kungabonakala.
• Imithambo yamaphaphu: Ungabona imithambo ethwala igazi lisuka emaphashini liye enhliziyweni.
• I-Thracic aorta: Lona umthambo wegazi oyinhloko oqala enhliziyweni futhi ungasetshenziswa ukuhlola izinkinga, njenge-aneurysms noma ukudabuka odongeni lwayo (ukuhlukana).
• I-Pericardium: Ulwelwesi oluncane oluzungeze inhliziyo lungahlolwa ukuze kubonakale ukuthi kukhona yini ukunqwabelana koketshezi noma ukuthi lujiyile (i-calcification).

Kukuziphi izimo udokotela angakutshela ukuthi wenze lokhu kuskena?

Udokotela angase atuse lokhu kuskena lapho edinga ukufunda ulwazi olujulile nolucacile mayelana nenhliziyo olungatholakali kwezinye izivivinyo. Isibonelo:

• Thola imbangela eqondile yobuhlungu besifuba sakho noma ukuphelelwa umoya .
• Hlola ukuthi imithambo yegazi yenhliziyo yakho ine-calcium noma amafutha (i-plaque) , inciphile noma ivalekile.
• EyakhoHlola ukuthi ama-valve enhliziyo asebenza kanjani.
• Hlola noma yiziphi izinkinga nge -aorta , njenge- aneurysms noma ukuqhekeka kwemithambo yegazi .
• Hlela kusengaphambili ukuhlinzwa kwenhliziyo okuvulekile noma ukuhlinzwa kwerobhothi.
• Yakha izindlela zokwelapha zesimanje, njengezinqubo ze-transcatheter valve .
• Hlela kusengaphambili ukwelashwa kwenhliziyo engajwayelekile (i-arrhythmia ablation) .
• Hlola ukuthi ngabe kukhona yini izinkinga eziye zenzeka ngemva kokuhlinzwa noma ukwelashwa okukhulunywe ngakho ngenhla.
• Thola ukuthi unenkinga yenhliziyo ozalwa nayo .
• Hlola isimila noma inqwaba enhliziyweni noma eduze kwaso bese uhlonza uhlobo lwaso.
• Hlola ukuthi uketshezi luqongelela noma ukuthi i-calcium ifakwa yini ku -pericardium , isikhwama esizungeze inhliziyo.

Uyini umehluko phakathi kwe-Cardiac CT ne-Cardiac MRI?

Abantu abaningi badida lezi zivivinyo ezimbili. Nakuba zombili zithatha izithombe ezicacile zenhliziyo, kukhona umehluko phakathi kwazo. Ake sibheke ukuthi ziyini.

Kufanele uzilungiselele kanjani ngaphambi kokuskena?

Ukuze uthole imiphumela emihle kakhulu kulokhu kuskena, udinga ukulungiselela kancane ngosuku olwandulelayo. Isibhedlela sizokunikeza imiyalelo ngalokhu, kodwa ake sixoxe ngezinto ezijwayelekile okudingeka uzazi.

Izinto okufanele uziqaphele lapho udla futhi uphuza

• Ngosuku lokuskena, ungadli lutho amahora amane kuya kwayisithupha ngaphambi kokuskena. Kodwa-ke, ungaphuza amanzi.
• Ungaphuzi lutho oluqukethe i-caffeine ngosuku olwandulelayo nangosuku lokuskena. Lokhu kusho ukugwema ikhofi, itiye, iziphuzo zamandla, kanye neziphuzo ezibandayo ezine-caffeine ngokuphelele. I-caffeine ingakhuphula izinga lokushaya kwenhliziyo yakho, okwenza kube nzima ukuthola isithombe esicacile.
• Futhi , uma usebenzisa izikhuthazi (amandla noma amaphilisi okunciphisa umzimba) , ungawaphuzi ngosuku olwandulela noma ngosuku lokuskena.

Izinto okufanele uzikhumbule ngemithi

• Uma une-claustrophobia, ungesabi. Tshela udokotela wakho ngakho kusenesikhathi. Angakunikeza umuthi wokudambisa ukuze akusize uphumule .
• Kubaluleke kakhulu ukwazisa udokotela wakho ngayo yonke imithi oyithathayo (kufaka phakathi leyo oyithatha ngaphandle kwencwadi kadokotela).
• Uma uthatha imithi efana ne -sildenafil (Viagra® noma i-Revatio®) , ungayithathi ngosuku olwandulela noma ngosuku lokuskena. Lokhu kungenxa yokuthi ingase ihlangane neminye imithi enikezwe ngesikhathi sokuskena. Uma ungaqiniseki, buza udokotela wakho.
• Uma unesifo sikashukela , buza udokotela wakho ukuthi ungayithatha kanjani imithi yakho ngosuku lokuskena. Uma uzizwa sengathi izinga likashukela egazini lakho liphansi, yazisa abasebenzi ngokushesha.

Yini ongayilindela ngosuku lokuskena?

Ngaphambi kokuskena, abasebenzi bazokubuza imibuzo embalwa. Kubalulekile ukuthi uyiphendule ngokunembile.

• Ukhulelwe ?
• Une-allergies ku-iodine noma ukudla kwasolwandle.Ingabe ikhona?
• Ingabe uthatha ukwelashwa ngemisebe ?
• Uma uneminyaka engaphezu kwengu-60 noma unezinkinga zezinso , kungadingeka ukuthi uhlolwe igazi ukuze kuhlolwe ukusebenza kwezinso zakho ngaphambi kokuba unikezwe idayi yokuhlukanisa.

Ungazilungiselela kanjani ukuskena

1. Okokuqala, udinga ukususa bonke ubucwebe bakho bese ugqoka ingubo ekhethekile enikezwe yisibhedlela.

2. Uma udinga ukunciphisa ijubane lokushaya kwenhliziyo yakho kancane ukuze uthole isithombe esicacile, ungasinika umuthi.

3. Uma kuzonikezwa idayi yokuhlukanisa, umhlengikazi uzofaka ithubhu elincane (umugqa we-IV) emthanjeni osengalweni yakho.

4. Uzobe usubekwa embhedeni okhethekile phakathi komshini we-CT.

5. Izindawo ezintathu zesifuba sakho zizohlanzwa bese kufakwa izitikha ezintathu ezincane (ama-electrode). Ungase futhi ususwe izinwele. Lawa ma-electrode azoxhunywa emshinini we-EKG oqopha umsebenzi kagesi wenhliziyo yakho.

6. Kuzodingeka ugcine izingalo zakho zingaphezu kwekhanda lakho sonke isikhathi lapho kwenziwa ukuskena. Ikhanda lakho nemilenze yakho kuzoba ngaphandle komshini.

Kwenzekani ngesikhathi sokuskena?

Yonke inqubo, okuhlanganisa nesikhathi sokulungiselela, ingathatha cishe imizuzu engama-30-60, kodwa ukuskena kwangempela kuthatha imizuzu engaphansi kweyi-10.

• Uzozwa umbhede olele kuwo ungena kancane kancane emshinini ofana nedonathi.
• Uma udayi wokungafani unikezwa nge-IV, kuvamile ukuzwa ukufudumala okuncane kanye nokunambitheka kwensimbi emlonyeni wakho njengoba kuhamba emzimbeni wakho. Lokhu kuzophela ngemizuzwana embalwa.
• Ukuze uthole izithombe ezicacile, kubaluleke kakhulu ukuthi uhlale uthule . Uma abasebenzi bekutshela ukuthi ubambe umoya wakho isikhashana , yenza kanjalo.

Ngemva kokuskena, ungaya ekhaya, udle, futhi wenze imisebenzi yakho evamile. Kodwa-ke, uma unikezwe umuthi wokudambisa, uzodinga umuntu ozokuhambisa ekhaya ngemoto. Udokotela wakho uzokuchazela imiphumela yokuskena ngosuku olufanayo noma ezinsukwini ezimbalwa.

Ingabe zikhona izingozi ngalesi sikeni?

I-CT scan iyisivivinyo esinobungozi obuphansi kakhulu, kodwa abanye abantu bangase babe nokusabela okuncane kudayi wokungafani noma ezinye izinto ezisetshenziswayo.

• Imiphumela engaba khona ye-Contrast Dye:Abanye abantu bangase babe nokusabela kokungezwani komzimba kulokhu. Lokhu kungafaka ukulunywa, isicanucanu, ukuthimula, kanye nokuqunjelwa. Lokhu kuvame ukuphela ngaphandle kokwelashwa. Akuvamile kakhulu, ukusabela okukhulu kokungezwani komzimba (ukusabela kwe-anaphylactic) okubangela ubunzima bokuphefumula kungenzeka. Lokhu kungaba yingozi empilweni futhi kudinga ukwelashwa ngokushesha. Uma unesifo sikashukela noma isifo sezinso, ungase ucelwe ukuthi uphuze uketshezi olwengeziwe ngemva kokuskena ukuze usize ukukhipha i-iodine emzimbeni wakho. Uma ungumama oncelisayo, kungcono ukukhipha ubisi lwebele ngaphambi kokuskena bese uncelisa ingane yakho usuku olulodwa noma ezimbili ngemva kokuskena, njengoba udayi osetshenziswa ekuskeneni ungadlulela obisini lwakho lwebele.
• Ukukhishwa kwemisebe: Ama-CT scan asebenzisa ama-X-ray. Ukuchayeka isikhathi eside kule misebe kungandisa kancane ingozi yakho yokuba nomdlavuza. Kodwa-ke, ukuze uphephe, inani lemisebe ekhishwa phakathi nalolu vivinyo ligcinwa lincane. Ngenxa yokuthi ama-X-ray angaba yingozi kumntwana osesiswini, lokhu kuhlolwa akukhuthazwa kwabesifazane abakhulelwe.

Iyini imiphumela futhi isho ukuthini?

Udokotela wakho uzokuchazela ukuthi yini esembikweni owutholayo ngemva kokuskena. Ngokuvamile, kunezinhlobo ezimbili zemiphumela.

Okokugcina, ungesabi i-Cardiac CT scan, noma umshini ngokwawo. Lokhu kuhlolwa okunikeza ulwazi olubalulekile ngesimo senhliziyo yakho ngaphandle kokwenza noma yikuphi ukusikwa emzimbeni wakho. Ukuze uthole imiphumela emihle kakhulu, landela imiyalelo enikezwe udokotela wakho kanye nabasebenzi basesibhedlela ngqo.
