Udokotela wakho kungenzeka ukuthi uncome ukuskena kwe-PET, futhi kungokwemvelo ukuzizwa ukhathazekile kancane uma uzwa igama elithi "scan." Sicela uqiniseke ukuthi akukho okufanele ukwesabe. Lobu ubuchwepheshe obuthuthukisiwe bokuxilonga obusivumela ukuthi siqonde ngokucacile ukuthi umzimba wakho usebenza kanjani nokuthi izimo ezithile zempilo zithuthuka kanjani. Ake sixoxe ngokuthi lokhu kuskena kuyini, kusebenza kanjani, nokuthi kungani kuyithuluzi eliphephile nelibalulekile lokunakekelwa kwakho eNirogi Lanka.
Yini ngempela eyenziwa yi-PET scan?
Kalula nje, i-PET scan iyisivivinyo esikhethekile esihlola ukuthi izitho zakho nezicubu zakho zisebenza kanjani. Ngokungafani ne-X-ray, i-CT, noma i-MRI—eqopha ngokuyinhloko izithombe zesakhiwo sangaphakathi lomzimba wakho—i-PET scan yembula ukuthi amangqamuzana akho asebenza kanjani ezingeni lamakhemikhali.
Ngaphambi kwenqubo, uzonikezwa i -radiotracer (inani elincane lento ekhipha imisebe). Ungavumeli igama elithi "radioactive" likukhathaze; liyithuluzi lokuxilonga eliphephile nelihlala isikhathi esifushane. I-PET scanner ithola ukuthi le nto ihamba kanjani emzimbeni wakho nokuthi iqoqana kuphi. Uma i-tracer iqoqana ezindaweni ezithile ngamanani aphezulu, ingabonisa udokotela wakho ukuthi kukhona isimo sempilo esingaphansi.
Isithwebuli se-PET ngokwaso sibukeka njengedonathi enkulu enetafula elingena liphume. Uzolala kuleli tafula ngesikhathi sokuskena. Ngokungafani neminye imishini ye-MRI, isithwebuli se-PET asiyona ithubhu evalekile ngokuphelele, okusiza iziguli eziningi zizizwe zingavalekile noma zingakhathazeki kakhulu.
Kusetshenziswa nini ama-PET scan?
Odokotela basebenzisa ama-PET scan ukuze bathole izifo, bahlele ukuhlinzwa, noma bahlole ukuthi ukwelashwa kusebenza kahle kangakanani. Asetshenziswa kakhulu ku-oncology (ukunakekelwa komdlavuza), i-cardiology, kanye ne-neurology.
Ngomdlavuza
Amaseli akho adinga amandla ukuze asebenze. Amaseli omdlavuza avame ukusebenza kakhulu futhi asebenzisa amandla amaningi kunamaseli anempilo. I-PET scan ingabona lokhu kusetshenziswa kwamandla aphezulu, okubangela ukuthi izindawo ezinamaseli omdlavuza zibonakale njengezindawo ezikhanyayo ezithombeni ze-scan. Ngokuvamile, i-PET scan ingabona izinkinga zempilo ngaphambi kokuba zivele kwezinye izinhlobo zezithombe.
Ngaphezu kwalokho, isetshenziswa:
- Thola ukuthi umdlavuza ususakazekele kwezinye izingxenye zomzimba.
- Hlola ukuthi ukwelashwa kwakho komdlavuza kusebenza kahle yini njengamanje.
- Qaphela noma yiziphi izimpawu zokubuyela emuva ngemva kokuphela kokwelashwa.
Ngesifo Senhliziyo
Ukuskena kwe-PET kungabonisa ukuthi inhliziyo yakho isebenza kahle kangakanani. Uma i-tracer ingena egazini lakho, ukuskena kukhombisa ukuthi igazi ligeleza kanjani liye ezingxenyeni ezahlukene zemisipha yenhliziyo. Uma indawo ithola ukugeleza kwegazi okulinganiselwe, kungase kubonise ukuvaleka noma umonakalo ovela ekuhlaselweni yinhliziyo kwangaphambilini.
Ngezimo Zobuchopho
Ukuskena kwe-PET kuyasiza ekuxilongeni izimo ezahlukahlukene zezinzwa, njenge:
- Isifo sika-Alzheimer
- Isifo sikaParkinson
- Isifo sikaHuntington
- Ukuquleka
- Ukushaya kwenhliziyo
- Izimila zobuchopho
Uyini umehluko phakathi kwe-PET, i-CT, ne-MRI?
Kuvamile ukudideka ngezinhlobo ezahlukene zokuskena. Nansi incazelo elula:
| Uhlobo Lokuskena | Indlela esebenza ngayo | Lokho okuboniswayo |
|---|---|---|
| Ukuskena kwezilwane ezifuywayo | Isebenzisa i-radioactive tracer ukukala umsebenzi weseli. | Kubonisa ukuthi izitho nezicubu zisebenza kanjani ezingeni lamaseli. |
| I-CT Scan | Isebenzisa ama-X-ray ukudala izithombe ezihlukanisa izingxenye. | Ibonisa isakhiwo nesimo samathambo, imithambo yegazi, kanye nezicubu ezithambile. |
| Iskeni se-MRI | Isebenzisa omaginethi abanamandla namagagasi omsakazo. | Inikeza izithombe zesakhiwo ezinemininingwane eminingi zezicubu ezithambile, umgogodla, kanye nobuchopho. |
Cabanga nge-CT kanye ne -MRI njengokuthatha isithombe esisezingeni eliphezulu se-anatomy yakho yangaphakathi, kuyilapho i-PET scan ifana kakhulu nevidiyo ekhombisa ukuthi lezo zitho zisebenza kanjani ngesikhathi sangempela.
Ngenxa yalokhu, odokotela bavame ukusebenzisa imishini exubile njenge-PET/CT noma i-PET/MRI, ehlanganisa izithombe zesakhiwo kanye nezisebenzayo ukuze inikeze ukuxilongwa okunembile kakhulu ngangokunokwenzeka.
Ukulungiselela ukuskena kwakho
Ukuqinisekisa ukuthi imiphumela yakho inembile, kunezinyathelo ezimbalwa ezibalulekile okufanele uzithathe ukuze ulungiselele ukuskena kwakho kwe-PET.
Yazisa udokotela wakho mayelana nalokhu:
- Ukungezwani komzimba: Ikakhulukazi ukusabela kumadayi ahlukile, i-iodine , noma ukudla kwasolwandle.
- Izimo Zezokwelapha: Sicela udalule ukuthi unesifo sikashukela (noma usebenzisa iphampu ye-insulin ).
- Imithi Yamanje: Nikeza uhlu lwazo zonke izidakamizwa, amavithamini, kanye nezithasiselo zemithi ozithathayo.
Izinto ezibalulekile okufanele uzicabangele:
- Uma uncelisa: Kungase kudingeke ukuthi ukhiphe ubisi bese ululahla isikhathi esithile kuze kube yilapho i-tracer isiphelile emzimbeni wakho. Sicela ubuze udokotela wakho isikhathi esinconywayo.
- Uma ukhulelwe noma usola ukuthi kungenzeka ukuthi: Lokhu kubaluleke kakhulu . Izinto ezisebenzisa imisebe ezisetshenziswe kulesi sikeni zingaba yingozi enganeni yakho. Sicela wazise udokotela wakho ngokushesha ukuze baxoxe ngezindlela eziphephile noma bahlehlise inqubo uma kudingeka.
Qaphela: Uma ubhekene nesimo esiphuthumayo sezokwelapha, sicela ushayele u-911 noma uvakashele umnyango wezimo eziphuthumayo oseduze nawe ngokushesha.
Umhlahlandlela wokulungiselela ukuskena ngaphambi kwesikhathi:
- Gwema noma yikuphi ukuvivinya umzimba okunzima okungenani amahora angama-24 ngaphambi kokuqokwa kwakho.
- Sicela uzile ukudla (ungadli noma uphuze ngaphandle kwamanzi) amahora ambalwa ngaphambi kokuhlolwa njengoba kuyalelwe.
- Susa zonke izinto zokuhloba zensimbi , okuhlanganisa amacici, imigexo, namasongo, ngaphambi kokuhlinzwa.
Ongakulindela ngesikhathi sokuskena kwakho kwe-PET
Nakuba kungase kube nokwehluka okuncane kuye ngokuthi umtholampilo kanye nesizathu esithile sokuskena kwakho, inqubo ejwayelekile eNirogi Lanka imi kanje:
1. Uzocelwa ukuthi ugqoke ingubo yasesibhedlela.
2. Uzothola ithuba lokusebenzisa indlu yangasese ngaphambi kokuba kuqale ukuskena.
3. Udokotela uzokunika 'i-tracer' emzimbeni wakho—lokhu kungaba ngomjovo, isiphuzo, noma igesi ephefumulwayo.
4. Kuzodingeka uphumule buthule imizuzu engama-30 kuya kwengama-60 ukuze umzimba wakho umunce ngokugcwele i-tracer.
5. Uzobe usubekwa embhedeni wesikena. Kubalulekile ukuthi uhlale uthule ngokuphelele, ungakhulumi noma unganyakazi , phakathi nokuskena. Lesi sigaba sivame ukuthatha eminye imizuzu engama-30 kuya kwengama-60.
Ungase uzwe umsindo wokubhonga noma wokuchofoza ovela emshinini; lokhu kuvamile. Ukuhlolwa akubuhlungu, yize ezinye iziguli zingase zizwe zingakhululekile ngenxa yokulala endaweni eyodwa isikhathi eside.
Ngemva kokuskena, phuza amanzi amaningi ukusiza umzimba wakho ukhiphe i-tracer. Ngenxa yokuthi umzimba wakho uzogcina inani elincane le-radioactivity amahora ambalwa, udokotela wakho angase akucebise ukuthi unciphise ukuxhumana eduze nabesifazane abakhulelwe, izinsana nezingane ezincane phakathi nalesi sikhathi esifushane.
Izingozi nemiphumela emibi
Ukuskena kwe-PET ngokuvamile kuyinqubo ephephile nejwayelekile. Kodwa-ke, kungase kube nezingozi ezincane noma ukungakhululeki:
- Uma unesifo sokwesaba izikhala ezivalekile, sicela usazise; udokotela wakho angakunikeza umuthi wokudambisa omnene ukukusiza uhlale uzolile.
- Uma unesifo sikashukela futhi ushukela wakho wegazi ungalawulwa kahle, kungase kuthinte ukunemba kwemiphumela yakho.
- Ungase uzwe ubuhlungu obuncane noma ukubomvu endaweni yokujova.
- Ukusabela kokungezwani komzimba ne-tracer akuvamile kakhulu futhi ngokuvamile kuncane.
- Isikhumbuzo esibalulekile: Ukuskena kwe-PET akwenziwa uma ukhulelwe noma uncelisa.
Ukuqonda imiphumela yakho
Uma ukuskena kwe-PET sekuqediwe, izindawo ezinomsebenzi omkhulu wamaseli zizovela njengezindawo ezikhanyayo ezithombeni. Nakuba lokhu kungabonisa isifo, kubaluleke kakhulu ukukhumbula ukuthi indawo ekhanyayo (umphumela omuhle) akusho ngokuzenzakalelayo ukuthi unomdlavuza.
Lezi zindawo zingabangelwa ukutheleleka, ukuvuvukala, noma ukukhula okungenabungozi. Ngaphezu kwalokho, ukuhlinzwa kwamuva, ukwelashwa ngamakhemikhali, noma ukwelashwa ngemisebe kungathinta okutholakele kuskeni. Sicela ungakhathazeki ngaphambi kwesikhathi. Udokotela wakho uzohlobanisa le miphumela namanye amarekhodi akho ezokwelapha kanye nomlando wezokwelapha ukuze anikeze isithombe esiphelele futhi uzochaza noma yiziphi izinyathelo ezilandelayo ezidingekayo.
Izinto Ezibalulekile Okufanele Uzicabangele
- I-PET scan ayibonisi nje izithombe zezitho zakho; ikhombisa ukuthi zisebenza kanjani . Kubalulekile ekuxilongeni umdlavuza, izimo zenhliziyo, kanye nezinkinga zezinzwa.
- Ukuskena ngokuvamile kuphephile, kodwa kufanele wazise udokotela wakho uma ukhulelwe, uncelisa, unesifo sikashukela, noma unesifo sokungezwani komzimba esaziwayo .
- Landela ngokuqinile yonke imiyalelo yangaphambi kokuskena (ukuzila ukudla, imikhawulo yomsebenzi womzimba, njll.).
- Indawo ekhanyayo esikeni akusho njalo umdlavuza. Ungesabi— bonana nodokotela wakho ukuze uthole incazelo enembile.
- Ngemva kokuskena, hlala unamanzi emzimbeni futhi ulandele zonke izeluleko zezokwelapha ngemuva kwenqubo.
Ukuskena kwe-PET, i-Positron Emission Tomography, umdlavuza, isifo senhliziyo, izinkinga zobuchopho, ukuhlolwa kwezokwelapha, ukuskena kwe-CT, ukuskena kwe-MRI, ukuskena kwe-PET
