Yintoni ukuskena kwentliziyo kwePET?

I-positron emission tomography (PET) yokuskena kwentliziyo luvavanyo lokucinga olusebenzisa idayi ekhethekileyo ukuvumela ugqirha wakho ukuba ajonge iingxaki ngentliziyo yakho.

Idayi iqulethe i-radioacac tracers, egxila kwiindawo zentliziyo ezinokuthi zenzakale okanye zigule. Usebenzisa iskena se-PET, ugqirha wakho unokuzibona ezi ndawo zixhalabisayo.

Ukuskena kwentliziyo kwe-PET ngokwesiqhelo yinkqubo yezigulana ezingalaliswayo, oko kuthetha ukuba akuyi kuhlala esibhedlele ubusuku bonke. Oku kuqhelekile yinkqubo yosuku olunye.

Kutheni kwenziwa ukuskena kwentliziyo kwe-PET

Ugqirha wakho unoku-odola ukuskena kwentliziyo kwe-PET ukuba unempawu zeengxaki zentliziyo. Iimpawu zengxaki yentliziyo zibandakanya:

• ukubetha kwentliziyo ngokungaqhelekanga (arrhythmia)
• intlungu esifubeni sakho
• ukuqina esifubeni sakho
• ingxaki yokuphefumla
• ubuthathaka
• ukubila kakhulu

Ugqirha wakho unokuyalela ukuskena kwentliziyo kwe-PET ukuba ezinye iimvavanyo zentliziyo, ezinje nge-echocardiogram (ECG) okanye uvavanyo loxinzelelo lwentliziyo, musa ukunika ugqirha wakho ulwazi olwaneleyo. Ukuskena kwentliziyo kwe-PET kunokusetyenziselwa ukulandelela ukusebenza kakuhle kwonyango lwezifo zentliziyo.

Umngcipheko wokuvavanywa kwentliziyo kwePET

Ngelixa i-scan isebenzisa i-radioactive tracers, ukubonakaliswa kwakho kukuncinci. Ngokwe-American College of Radiology Imaging Network, inqanaba lokuvezwa liphantsi kakhulu ukuba lingachaphazela iinkqubo eziqhelekileyo zomzimba wakho kwaye alithathwa njengomngcipheko omkhulu.

Eminye imingcipheko yokuvavanywa kwentliziyo ye-PET ibandakanya:

• iimvakalelo ezingathandekiyo ukuba ungo-claustrophobic
• Intlungu encinci evela kwinaliti
• ukukhathazeka kwesihlunu ekubekeni kwitafile enzima yovavanyo

Ezi zibonelelo zovavanyo zibudlula kude ubungozi obuncinci.

Nangona kunjalo, imitha inokuba yingozi kwimveku okanye usana olusandul 'ukuzalwa. Ukuba ukrokrela ukuba ukhulelwe, okanye unesi, ugqirha wakho unokucebisa olunye uhlobo lovavanyo.

Uyilungiselela njani ukuskena kwentliziyo ye-PET

Ugqirha wakho uya kukubonelela ngemiyalelo epheleleyo malunga nokulungiselela ukuskena kwentliziyo yakho kwi-PET scan. Tshela ugqirha wakho malunga nawaphi na amayeza onokuthi uwathathe, nokuba ngaba ngugqirha, ekhawuntareni, okanye kwizongezo zesondlo.

Unokuyalelwa ukuba ungatyi nantoni na ukuya kuthi ga kwiiyure ezisibhozo ngaphambi kwenkqubo yakho. Kodwa ke uya kukwazi ukusela amanzi.

Ukuba ukhulelwe, kholelwa ukuba unokukhulelwa, okanye unesi, xelela ugqirha wakho. Olu vavanyo lunokungakhuseleki kumntwana wakho ongekazalwa okanye oncancisayo.

Kuya kufuneka uxelele ugqirha wakho malunga nayo nayiphi na imeko yonyango onayo. Umzekelo, ukuba unesifo seswekile, unokufuna imiyalelo ekhethekileyo yovavanyo, njengoko ukuzila ukutya kwangaphambili kunokuba nefuthe kumanqanaba eswekile yegazi.

Ngokukhawuleza ngaphambi kovavanyo, unokucelwa ukuba utshintshe ube yingubo yesibhedlele kwaye ususe bonke ubucwebe bakho.

Yenziwa njani ukuskena kwentliziyo kwePET

Okokuqala, uya kuhlala esihlalweni. Ingcali iya kuthi emva koko ifake i-IV engalweni yakho. Ngale IV, idayi ekhethekileyo enee-radioacac tracers iya kutofelwa kwimithambo yakho. Umzimba wakho udinga ixesha lokufunxa iitracers, ke uya kulinda malunga neyure. Ngeli xesha, itekhnoloji iya kuthi incamathisele ii-electrode ze-electrocardiogram (ECG) esifubeni sakho ukuze izinga lokubetha kwentliziyo yakho libe nakho ukubekwa esweni.

Okulandelayo, uya kungena scan. Oku kubandakanya ukulala etafileni emxinwa eqhotyoshelwe kumatshini wePET. Itheyibhile iya kuthwaleka ngokuthe chu kwaye ngokutyibilikayo kumatshini. Kuya kufuneka uphinde uxoke nangoku kunokwenzeka ngexesha lokuskena. Ngamaxesha athile, igcisa liya kukuxelela ukuba uhlale ungashukumi. Oku kuvumela ukuba kuthathwe imifanekiso ecacileyo.

Emva kokuba imifanekiso echanekileyo igcinwe kwikhompyuter, uya kuba nakho ukutyibilika ngaphandle komatshini. Ingcali iya kuthi emva koko isuse ii-electrode, kwaye uvavanyo lugqityiwe.

Emva kokuvavanywa kwentliziyo kwePET

Ngumbono olungileyo ukusela ulwelo oluninzi emva kovavanyo ukunceda ukukhupha iitracers ngaphandle kwenkqubo yakho. Ngokubanzi, zonke iitreacer zikhutshwa ngokwendalo emzimbeni wakho emva kweentsuku ezimbini.

Ingcali eqeqeshwe ekufundeni i-PET scan iya kuyitolika imifanekiso yakho kwaye yabelane ngolwazi olo nogqirha wakho. Ugqirha wakho uya kuthi emva koko ahambisane neziphumo kunye nawe kwisithuba sokulandela.

Yintoni enokufunyanwa kukuskena kwentliziyo kwe-PET

Iskena se-PET sentliziyo sinika ugqirha wakho umfanekiso ocacileyo wentliziyo yakho. Oku kuvumela ukuba babone ukuba zeziphi iindawo zentliziyo ezifumana ukwehla kokuhamba kwegazi kwaye zeziphi iindawo ezonakalisiweyo okanye eziqulathe izicwili ezibomvu.

Isifo semithambo yegazi (CAD)

Usebenzisa imifanekiso, ugqirha wakho unokufumanisa isifo se-coronary disease (CAD). Oku kuthetha ukuba imithambo ephethe igazi kunye neoksijini entliziyweni yakho iye yanzima, yancipha, okanye yavalwa. Banokuthi emva koko ba-odole i-angioplasty okanye ukufakwa kwesenti ukwandisa umthambo kunye nokunciphisa nakuphi na ukunciphisa.

I-angioplasty ibandakanya ukubeka i-catheter encinci (ityhubhu ethambileyo) ngebhaluni kwincam yayo ngesitya segazi de ifike kumthambo omncinci, ovaliweyo. Nje ukuba i-catheter ikwindawo oyifunayo, ugqirha wakho uya kuyifaka ibhaluni. Le bhaluni iya kucinezela i-plaque (unobangela wokuvaleka) ngokuchasene nodonga lwemithambo. Igazi linokuhamba ngokutyibilikayo ngomthambo.

Kwiimeko ezinzulu ze-CAD, kuya kwenziwa utyando lwe-coronary bypass. Olu tyando lubandakanya ukufaka incindi yomthambo emlenzeni wakho okanye umthambo osuka esifubeni sakho okanye esihlahleni ukuya kwimithambo yegazi engaphezulu nangaphantsi kwendawo emxinwa okanye evaliweyo. Lo mthambo okanye umthambo usandula ukudityaniswa uya kuvumela igazi ukuba "lidlule" kumthambo owonakeleyo.

Ukumelwa yintliziyo

Ukungaphumeleli kwentliziyo kufunyaniswa xa intliziyo ingasakwazi ukubonelela ngegazi eloneleyo kuwo wonke umzimba wakho. Ityala elibi le-coronary artery disease lidla ngokuba ngunobangela.

Ukungaphumeleli kwentliziyo kunokubangelwa:

• isifo sentliziyo
• isifo sentliziyo esibelekwe
• ukuhlaselwa yintliziyo
• isifo sentliziyo
• Iingqungquthela zentliziyo engaqhelekanga (arrhythmias)
• izifo ezifana ne-emphysema, i-thyroid okanye i-anemia

Kwimeko yokusilela kwentliziyo, ugqirha wakho unokumisela amayeza okanye utyando. Banoku-odola i-angioplasty, utyando lwe-coronary bypass, okanye utyando lwentliziyo lwevalvu. Ugqirha wakho unokufuna ukufaka i-pacemaker okanye i-defibrillator, ezizizixhobo ezigcina ukubetha kwentliziyo rhoqo.

Kuxhomekeka kwiziphumo zakho, ugqirha wakho angathetha nawe malunga nokuqhubeka kokuvavanywa kunye nonyango.
