Ngaba ugqirha wakho ukuxelele ukuba wenze i-'Cardiac PET Scan' ukuze ujonge intliziyo yakho? Usenokoyika kancinci xa usiva igama. "Luthini olu vavanyo ludumileyo? Ngaba lunzima? Ngaba lubuhlungu?" Usenokuba uzibuza. Kodwa ungakhathazeki. Ngamafutshane, olu luvavanyo oluphambili kakhulu olunokuhlola impilo yentliziyo yakho ngendlela eneenkcukacha kakhulu nechanekileyo. Masithethe ngalo ngokulula.

Yintoni kanye kanye iCardiac PET Scan?

Khawucinge ukuba bekukho indlela yokujonga ngaphakathi entliziyweni yakho ukuze ubone indlela ezisebenza ngayo iiseli, ukuba zifumana igazi elaneleyo na, nokuba kukho umonakalo na. Yiloo nto eyenziwa lolu vavanyo lwePET (Positron Emission Tomography).

Nantsi into eyenzekayo: I-tracer encinci kakhulu nekhuselekileyo ye-radioactive ifakwa emzimbeni wakho. Ayisiyodayi okanye i-agent yokwahlulahlula. Ihamba ngegazi lakho iye kwiiseli zentliziyo. Emva koko, i-PET scanner enekhamera ekhethekileyo ibona amandla akhutshwa yi-tracer ize yenze imifanekiso yekhompyutha yentliziyo yakho enamacala amathathu (3D).

Eyona ndlela ikhethekileyo kukuba iyakwazi ukubona iingxaki zentliziyo kwangethuba kunezinye iintlobo ze-scan. Ngamanye amaxesha i-PET scan yenziwa kunye ne-CT (Computed Tomography) scan. Emva koko, zombini ezi ntlobo ze-scan zingenziwa kumatshini omnye, zinike umfanekiso ocacileyo wentliziyo.

Kuphantsi kweziphi iimeko apho ugqirha angacebisa olu vavanyo?

Olu vavanyo lumiselwa kuphela xa ugqirha wakho efuna ukwazi into ethile ngentliziyo yakho. Umzekelo:

Jonga ukuba kukho ukunqongophala okukhulu kwegazi kwiindawo ezithile zentliziyo: Ngamanye amaxesha imithambo yegazi ehambisa igazi kwimisipha yentliziyo inokuvaleka. Oku kuya kunceda ukubona ukuba oku kunjalo na.
Jonga ukuba unesifo semithambo yegazi yentliziyo.
Fumanisa ukuba kukho na isifo semisipha yentliziyo.
Fumanisa ukuba kukho isifo sentliziyo okanye imeko ethile yezonyango efana neCardiac Sarcoidosis.
Linganisa ukuba ungakanani umonakalo owenziwe entliziyweni emva kokuhlaselwa yintliziyo.
Jonga indlela ephumelele ngayo isicwangciso sonyango.
Gqiba ukuba uza kuzuza na kwinkqubo ethile.
Jonga impilo yentliziyo yakho ngaphambi kotyando.

Ndingayilungiselela njani le scan?

Ukuze ufumane iziphumo ezichanekileyo kolu vavanyo, kubaluleke kakhulu ukulandela imiyalelo kagqirha wakho ngokuchanekileyo. Makhe sijonge indlela yokulungiselela ngokubanzi.

Icandelo eliza kulungiswa	Izinto ekufuneka zilandelwe
Ukutya neziselo	Musa ukutya okanye ukusela nantoni na ngaphandle kwamanzi kangangeeyure ezi-4 ngaphambi kovavanyo. Musa ukutya nantoni na ene-caffeine iiyure ezingama-24 ngaphambi kovavanyo. (Umzekelo: ikofu, iti, i-cola, itshokolethi, amaqunube). Ziphephe nezo zibhalwe "decaf" okanye "ezingenayo i-caffeine" kuba zisenazo ii-caffeine ezincinci. Ukuba ufuna iCardiac Sarcoidosis okanye usulelo, uza kuxelelwa ukuba utye ukutya okunamafutha amaninzi, okune-carbohydrate ephantsi kangangeeyure ezingama-24-48. Nangona kunjalo, oku akusoloko kuyimfuneko.
Ukuzilolonga nokutshaya	Musa ukwenza naluphi na uhlobo lomthambo onzima iiyure ezingama-24 ngaphambi kovavanyo. Musa ukutshaya ngomhla wovavanyo. I-Nicotine inokuchaphazela iziphumo.
Amayeza	Phatha uluhlu lwamayeza onke (kuquka neevithamini) owasebenzisayo. Yeka ukuthatha iipilisi zokunciphisa umzimba ezine-caffeine kunye neepilisi zokunciphisa umzimba iiyure ezingama-24 ngaphambi kwexesha. Ukuba une-asthma: Uza kucelwa ukuba uyeke ukusebenzisa amayeza afana ne-theophylline kwiiyure ezingama-48 kwangaphambili. Qiniseka ukuba uzisa i-inhaler yakho. Ukuba unesifo seswekile: Ukuba uthatha i-insulin, buza ugqirha wakho malunga nendlela yokuthatha idosi yakho yemihla ngemihla. Basenokukuxelela ukuba uthathe isiqingatha sedosi yakho kusasa uze utye ukutya okulula iiyure ezi-4 ngaphambi. Ukuba uthatha iipilisi, banokukuxelela ukuba ungazithathi ngaphambi kovavanyo. Zisa amayeza akho uze uwathathe emva kovavanyo. Kukwangumbono olungileyo ukuzisa i-glucose monitor. Amayeza entliziyo: Musa ukuyeka ukusebenzisa amayeza ngaphandle kokuba ugqirha wakho ekuxelele ukuba wenjenjalo. Amanye amayeza (umz., iNitroglycerin, iDipyridamole) aya kuba nemiyalelo yendlela yokuyeka.

Kwenzeka ntoni ngexesha leskeni?

Lonke uvavanyo lungathatha phakathi kweyure enye ukuya kwezintathu, kodwa ungaphakathi kwiskena malunga nemizuzu engama-30 kuphela.

Ngaphambi kokuba uvavanyo luqale, uza kunikwa ilokhwe yesibhedlele oza kuyinxiba kwaye uxinzelelo lwakho lwegazi luza kuhlolwa. Emva koko, ezi zinto zilandelayo ziya kwenzeka ngokulandelelana kwazo:

1. Ukudibanisa i-EKG: Ukuze kujongwe ukusebenza kombane kwentliziyo yakho, ii-electrode ezininzi, ezifana nezitikha ezingenabuhlungu, zifakwa esifubeni sakho. Ezi zihlala zisendaweni yazo yonke uvavanyo.

2. Ukufaka i-cannula efakwa kwimithambo yegazi (IV): I-cannula encinci ifakwa kumthambo osengalweni yakho ukuze ikunike iyeza kunye nezinto ezisebenzisa i-radioactive.

3. Ukulala kwiskena: Uza kuphoswa ebhedini phakathi komatshini omkhulu ofana nedonathi enesithuba esingenanto embindini. Kubalulekile ukuba ungashukumi ngeli xesha.

4. Iskeni sokuqala (Iskeni Yokuphumla): Inani elincinci lezinto ezinemisebe lifakwa kwi-cannula, kwaye ukuhamba kwegazi entliziyweni yakho kuyaskeniwa ngelixa uphumle.

5. Ukuzilolonga Intliziyo: Okulandelayo, kunikwa amayeza akhethekileyo nge-cannula ukwenza intliziyo yakho ivakale ngathi uyazilolonga. Usenokuziva ushushu, ubanda, okanye unentloko ebuhlungu kancinci ngeli xesha. Oku kuqhelekile.

6. Ukuskena okwesibini (Stress Scan): Ngelixa intliziyo ikwimeko "esebenzayo", kufakwa inani elincinci lezinto ezinemisebe kwakhona kwaye kuskenwe.

Okokugqibela, ugqirha uthelekisa ezi scan zimbini (ukuphumla kunye noxinzelelo) ukuze afikelele kwisigqibo malunga nemeko yentliziyo.

Ukuba ufumana naluphi na uvakalelo olungathandekiyo ngexesha lovavanyo, olufana nentlungu yesifuba, ingalo, okanye umhlathi, ubunzima bokuphefumla, okanye isiyezi, yazisa abasebenzi ngoko nangoko.

Kwenzeka ntoni emva kovavanyo? Kwaye ngaba kukho naziphi na iingozi?

Xa uvavanyo luphelile, i-cannula engalweni yakho iya kususwa. Ungagoduka unxibe impahla eqhelekileyo. Nangona kunjalo, ukuba unikwe iyeza lokuthomalalisa, awuyi kukwazi ukuqhuba. Kukhuselekile ukuhamba nomnye umntu.

Kubaluleke kakhulu: Sela amanzi amaninzi iiyure ezingama-24 emva kovavanyo. Oku kuya kunceda ukuba izinto ezinemisebe ezifakwe emzimbeni wakho zisuswe ngokukhawuleza emzimbeni wakho ngomchamo wakho.

Iziphumo ebezingalindelekanga kunye neengozi	Inkcazo
Iziphumo ebezingalindelekanga ezincinci	Umphezulu wolusu apho i-cannula ifakwe khona unokuba bomvu kancinci kwaye kunokubakho iintlungu ezingephi okwethutyana. Umngcipheko wokuba umntu angabi namdla kwizinto ezisebenzisa i-radioactive uphantsi kakhulu . Ubungakanani be-radiation esetyenziswayo buphantsi kakhulu kwaye bukhuselekile.
Iingozi ezikhethekileyo	Ukuba ukhulelwe okanye uncancisa , qiniseka ukuba uxelele ugqirha wakho, njengoko le radiation inokuba yingozi kumntwana ongakazalwa okanye kumntwana oncancisayo. Iziphumo zabantu abanesifo seswekile zisenokungachaneki kangako. Ukuba une-claustrophobia, ungaziva ungakhululekanga ngexesha lokuskena. Ukuba uxelelwe oku kwangaphambili, unganikwa iyeza lokuthomalalisa. Abantu abane-body mass index (BMI) abangaphezu kwama-30 banokufuna i-scanner ekhethekileyo.
