Kuyini ukuskena kwenhliziyo kwe-PET?

Ukuskena kwenhliziyo kwe-positron emission tomography (PET) kuyisivivinyo sokucabanga esisebenzisa udayi okhethekile ukuvumela udokotela wakho ukuthi abuke izinkinga ngenhliziyo yakho.

Idayi iqukethe ama-tracers e-radioactive, agxila ezindaweni zenhliziyo ezingalimala noma zigule. Usebenzisa isithwebuli se-PET, udokotela wakho angazibona lezi zindawo ezikhathazayo.

Ukuskena kwenhliziyo kwe-PET imvamisa kuyindlela yokwelashwa ngaphandle, okusho ukuthi ngeke kudingeke uhlale esibhedlela ubusuku bonke. Lokhu kuyinqubo yosuku olufanayo.

Kungani kwenziwa i-PET scan yenhliziyo

Udokotela wakho anga-oda ukuskena kwenhliziyo kwe-PET uma uhlangabezana nezimpawu zenkinga yenhliziyo. Izimpawu zenkinga yenhliziyo zifaka:

• ukushaya kwenhliziyo okungajwayelekile (arrhythmia)
• ubuhlungu esifubeni sakho
• ukuqina esifubeni sakho
• inkinga yokuphefumula
• ubuthakathaka
• ukujuluka okukhulu

Udokotela wakho angaphinde a-ode ukuskena kwenhliziyo kwe-PET uma ezinye izivivinyo zenhliziyo, njenge-echocardiogram (ECG) noma ukuhlolwa kwengcindezi yenhliziyo, zinganikezi udokotela wakho ulwazi olwanele. Ukuskena kwe-PET kwenhliziyo kungasetshenziswa ukulandelela ukusebenza kahle kwezindlela zokwelashwa kwezifo zenhliziyo.

Izingozi zokuskena kwenhliziyo kwe-PET

Ngenkathi i-scan isebenzisa ama-tracers e-radioactive, ukuvezwa kwakho kuncane. Ngokwe-American College of Radiology Imaging Network, izinga lokuchayeka liphansi kakhulu ukuthi lingathinta izinqubo ezijwayelekile zomzimba wakho futhi alithathwa njengengozi enkulu.

Ezinye izingozi zokuskena kwenhliziyo kwe-PET zifaka:

• imizwa engakhululekile uma uyi-claustrophobic
• ubuhlungu obuncane obuvela enalithini
• ukukhathazeka kwemisipha ekubekeni etafuleni lokuhlola elinzima

Izinzuzo zalesi sivivinyo zidlula kude ubungozi obuncane.

Noma kunjalo, imisebe ingaba yingozi kumntwana noma ingane esanda kuzalwa. Uma usola ukuthi kungenzeka ukhulelwe, noma unesi, udokotela wakho angancoma enye indlela yokuhlolwa.

Ungakulungiselela kanjani ukuskena kwenhliziyo kwe-PET

Udokotela wakho uzokunikeza imiyalo ephelele mayelana nokulungiselela ukuskena kwenhliziyo yakho kwe-PET. Tshela udokotela wakho nganoma imiphi imithi okungenzeka uyayiphuza, noma ngabe udokotela, i-over-the-counter, noma izithako zokudla okunempilo.

Ungayalwa ukuthi ungadli lutho kuze kufike emahoreni ayisishiyagalombili ngaphambi kwenqubo yakho. Kodwa-ke uzokwazi ukuphuza amanzi.

Uma ukhulelwe, kholelwa ukuthi kungenzeka ukhulelwe, noma ungumhlengikazi, tshela udokotela wakho. Lokhu kuhlolwa kungaphepha enganeni yakho engakazalwa noma encelisayo.

Kufanele futhi utshele udokotela wakho nganoma yiziphi izimo zezokwelapha onazo. Isibonelo, uma unesifo sikashukela, ungadinga imiyalo ekhethekile yokuhlolwa, ngoba ukuzila ukudla ngaphambi kwesikhathi kungathinta amazinga kashukela egazini lakho.

Masinyane ngaphambi kokuhlolwa, ungacelwa ukuthi ushintshe ugqoke isibhedlela futhi ususe bonke ubucwebe bakho.

Kwenziwa kanjani ukuskena kwe-PET kwenhliziyo

Okokuqala, uzohlala esihlalweni. Uchwepheshe uzobe esefaka i-IV engalweni yakho. Ngalolu IV, kuzofakwa udayi okhethekile onezicucu ezikhipha imisebe emithanjeni yakho. Umzimba wakho udinga isikhathi sokumunca amathrekhi, ngakho-ke uzolinda cishe ihora. Ngalesi sikhathi, uchwepheshe uzonamathisela ama-electrode we-electrocardiogram (ECG) esifubeni sakho ukuze izinga lokushaya kwenhliziyo yakho nalo libhekwe.

Okulandelayo, uzohlolwa. Lokhu kufaka ukulala etafuleni elincanyana elixhunywe emshinini we-PET. Itafula lizoshibilika kancane futhi ngokushelela emshinini. Kuzodingeka uqambe amanga ngangokunokwenzeka ngesikhathi sokuskena. Ngezikhathi ezithile, uchwepheshe uzokutshela ukuthi uhlale unganyakazi. Lokhu kuvumela ukuthi kuthathwe izithombe ezicace bha.

Ngemuva kokuthi izithombe ezifanele zigcinwe kwikhompyutha, uzokwazi ukuphuma emshinini. Uchwepheshe uzobe esusa ama-electrode, bese ukuhlolwa kuqediwe.

Ngemuva kokuhlolwa kwe-PET kwenhliziyo

Kungumqondo omuhle ukuphuza uketshezi oluningi ngemuva kokuhlolwa ukusiza ukukhipha izingcingo kuhlelo lwakho. Ngokuvamile, wonke ama-tracers akhishwa ngokwemvelo emzimbeni wakho ngemuva kwezinsuku ezimbili.

Uchwepheshe oqeqeshwe ekufundeni izikena ze-PET uzohumusha izithombe zakho bese wabelana ngolwazi lwakho nodokotela wakho. Udokotela wakho uzobe esehamba nawe ngemiphumela ekuqokweni okulandelayo.

Yeka ukutholwa kwenhliziyo kwe-PET

Iskena se-PET senhliziyo sinikeza udokotela wakho isithombe esiningiliziwe senhliziyo yakho. Lokhu kubenza bakwazi ukubona ukuthi yiziphi izindawo zenhliziyo ezibhekene nokuncipha kwegazi nokuthi yiziphi izindawo ezilimele noma eziqukethe izicubu ezibomvu.

Isifo semithambo yegazi (CAD)

Usebenzisa izithombe, udokotela wakho angathola isifo se-coronary artery disease (CAD). Lokhu kusho ukuthi imithambo ehambisa igazi ne-oksijini enhliziyweni yakho seyenze lukhuni, yancipha noma yavimba. Bangabe-ke be-oda i-angioplasty noma ukufakwa kwama-stents ukukhulisa umthambo futhi kunciphise noma yikuphi ukuncipha.

I-angioplasty ihilela ukubeka ipayipi elincane (ishubhu elithambile) ngebhaluni esicutshini salo ngomthambo wegazi lize lifinyelele emthanjeni omncane, ovinjiwe. Uma i-catheter isendaweni oyifunayo, udokotela wakho uzofaka ibhaluni. Leli bhaluni lizocindezela uqweqwe (imbangela yokuvalwa) lubhekane nodonga lwemithambo. Igazi bese ligobhoza ngokushelela emthanjeni.

Ezimweni ezibucayi ze-CAD, kuzohlinzwa i-coronary bypass. Lokhu kuhlinzwa kubandakanya ukufaka ingxenye yomthambo emlenzeni wakho noma umthambo osuka esifubeni sakho noma esihlakaleni uye emthanjeni we-coronary ngenhla nangaphansi kwendawo encishisiwe noma evinjiwe. Lo mthambo noma umthambo osanda kufakwa uzobe uvumela igazi ukuthi “lidlule” umthambo owonakele.

Ukwehluleka kwenhliziyo

Ukwehluleka kwenhliziyo kutholakala lapho inhliziyo ingasakwazi ukunikeza igazi elanele kuwo wonke umzimba wakho. Isimo esinzima sesifo semithambo yenhliziyo ngokuvamile siyimbangela.

Ukwehluleka kwenhliziyo nakho kungabangelwa:

• isifo senhliziyo
• isifo senhliziyo esizalwa naso
• isifo senhliziyo
• isifo senhliziyo senhliziyo
• isigqi senhliziyo esingajwayelekile (arrhythmias)
• izifo ezifana ne-emphysema, i-thyroid engasebenzi ngokweqile noma engasebenzi kahle, noma i-anemia

Endabeni yokwehluleka kwenhliziyo, udokotela wakho angakunika imishanguzo noma ahlinze uku-oda. Bangase ba-ode i-angioplasty, i-coronary bypass surgery, noma ukuhlinzwa kwe-valve yenhliziyo. Udokotela wakho angafuna futhi ukufaka i-pacemaker noma i-defibrillator, okuyizinto ezigcina ukushaya kwenhliziyo okuvamile.

Ngokuya ngemiphumela yakho, udokotela wakho angakhuluma nawe ngokuqhubeka nokuhlolwa nokwelashwa.
