• Jonga ukuba akukho manzi aqokeleleneyo okanye i-calcium edityanisiweyo kwi -pericardium , ingxowa ejikeleze intliziyo.

Yintoni umahluko phakathi kweCardiac CT kunye neCardiac MRI?

Abantu abaninzi bayabhideka kwezi mvavanyo zimbini. Nangona zombini zithatha imifanekiso ecacileyo yentliziyo, kukho umahluko phakathi kwezi zimbini. Makhe sijonge ukuba ziyintoni na.

Ufanele uzilungiselele njani ngaphambi kokuba uskene?

Ukuze ufumane iziphumo ezilungileyo kolu vavanyo, kufuneka ulungiselele kancinci ngosuku olungaphambi kolu vavanyo. Isibhedlele siza kukunika imiyalelo ngalo mba, kodwa makhe sixoxe ngezinto eziqhelekileyo ekufuneka uzazi.

Izinto ekufuneka uzilumkele xa usitya kwaye usela

• Ngomhla wokuhlolwa, musa ukutya nantoni na iiyure ezine ukuya kwezintandathu ngaphambi kokuhlolwa. Nangona kunjalo, ungasela amanzi.
• Musa ukusela nantoni na ene-caffeine ngosuku olungaphambi nangosuku lokuskena. Oku kuthetha ukuba ungayisebenzisi ngokupheleleyo ikofu, iti, iziselo ezinika amandla, kunye neziselo ezibandayo ezine-caffeine. I-caffeine inokunyusa izinga lentliziyo yakho, nto leyo eyenza kube nzima ukufumana umfanekiso ocacileyo.
• Kwakhona , ukuba usebenzisa izinto ezivuselelayo (iipilisi zamandla okanye zokunciphisa umzimba) , musa ukuzithatha ngosuku olungaphambi okanye ngosuku lokuskena.

Izinto ekufuneka uzikhumbule malunga namayeza

• Ukuba une-claustrophobia, musa ukoyika. Xelela ugqirha wakho ngayo kwangethuba. Angakunika iyeza lokuthomalalisa elinokukunceda uphumle .
• Kubaluleke kakhulu ukwazisa ugqirha wakho malunga nawo onke amayeza owasebenzisayo (kuquka lawo uwasebenzisa ngaphandle kwemvume kagqirha).
• Ukuba usebenzisa amayeza afana ne -sildenafil (Viagra® okanye iRevatio®) , musa ukuwasebenzisa ngosuku olungaphambi okanye ngosuku lokuskena. Oku kungenxa yokuba asenokudibana namanye amayeza anikwe ngexesha lokuskena. Ukuba awuqinisekanga, buza ugqirha wakho.
• Ukuba unesifo seswekile , buza ugqirha wakho malunga nendlela yokusela amayeza akho ngomhla wokuhlolwa. Ukuba uvakalelwa kukuba iswekile yakho egazini iphantsi, yazisa abasebenzi ngoko nangoko.

Yintoni onokuyilindela ngomhla wokuskena?

Ngaphambi kokuba kuskeniwe, abasebenzi baza kukubuza imibuzo embalwa. Kubalulekile ukuba uyiphendule ngokuchanekileyo.

• Ukhulelwe ?
• Une-allergies kwi-iodine okanye kwizilwanyana zaselwandle.Ngaba ikho na?
• Ngaba uthatha unyango lwe-radiation ?
• Ukuba ungaphezulu kweminyaka engama-60 okanye unengxaki yezintso , kunokufuneka ukuba uhlolwe igazi ukuze kuhlolwe ukusebenza kwezintso zakho ngaphambi kokuba unikwe idayi yokwahlulahlula.

Indlela yokuzilungiselela iskeni

1. Okokuqala, kufuneka ukhuphe zonke izinto zakho zobucwebe uze unxibe ilokhwe ekhethekileyo ebonelelwe yisibhedlele.

2. Ukuba ufuna ukunciphisa isantya sentliziyo yakho ukuze ufumane umfanekiso ocacileyo, ungayinika iyeza.

3. Ukuba uza kunikwa idayi yokwahlulahlula, umongikazi uza kufaka ityhubhu encinci (umgca we-IV) kumthambo osengalweni yakho.

4. Emva koko uya kulaliswa ebhedini ekhethekileyo phakathi komatshini we-CT.

5. Iindawo ezintathu zesifuba sakho ziya kucocwa kwaye kuya kufakwa izitikha ezintathu ezincinci (ii-electrode). Ungasuswa neenwele ezithile. Ezi electrode ziya kuqhagamshelwa kumatshini we-EKG orekhoda umsebenzi wombane wentliziyo yakho.

6. Kuya kufuneka ugcine iingalo zakho zingaphezulu kwentloko yakho ngalo lonke ixesha kusenziwa iskeni. Intloko nemilenze yakho ziya kuba ngaphandle komatshini.

Kwenzeka ntoni ngexesha leskeni?

Yonke le nkqubo, kuquka nexesha lokulungiselela, ingathatha malunga nemizuzu engama-30-60, kodwa ukuskena ngokoqobo kuthatha ngaphantsi kwemizuzu eli-10.

• Uza kuziva ibhedi olele kuyo ingena kancinci kancinci kumatshini omile okwedonati.
• Xa idayi yomahluko inikwa nge-IV, kuyinto eqhelekileyo ukuziva ubushushu obuncinci kunye nencasa yesinyithi emlonyeni wakho njengoko ihamba emzimbeni wakho. Oku kuya kuphela kwimizuzwana embalwa.
• Ukuze ufumane imifanekiso ecacileyo, kubaluleke kakhulu ukuba uhlale ungashukumi . Ukuba abasebenzi bakuxelela ukuba ubambe umphefumlo wakho okomzuzwana , yenza njalo.
