Ukuskena kwe-Lung PET
I-Positron emission tomography (PET) inqubo eyinkimbinkimbi yezithombe zezokwelapha. Isebenzisa i-tracer enemisebe ukukhomba umehluko ezicutshini ezingeni lamangqamuzana. Ukuskena umzimba wonke kwe-PET kungabona umehluko ekusebenzeni komzimba, njengokugeleza kwegazi, ukusetshenziswa komoya-mpilo, kanye nokutholwa kwama-molecule kashukela (glucose). Lokhu kuvumela udokotela wakho ukuthi abone ukuthi izitho ezithile zisebenza kanjani.
Ngezinkinga zamaphaphu, udokotela angabe esebheka ngqo indawo yamaphaphu ngenkathi ehumusha izithombe ezithwetshulwa yi-PET.
Iskena se-lung PET ngokuvamile sihlanganiswa ne-lung CT scan ukuthola izimo ezinjengomdlavuza wamaphaphu. Ikhompiyutha ihlanganisa imininingwane evela kuzikena ezimbili ukuze inikeze isithombe esinobukhulu obuthathu, esigcizelela noma yiziphi izindawo zomsebenzi osheshayo we-metabolic. Le nqubo yaziwa njengokuhlanganiswa kwesithombe. Izikena zivumela udokotela wakho ukuthi ahlukanise phakathi kwezixuku ezinobungozi (ezingabangeli umdlavuza) neziyingozi (ezinomdlavuza).
Kwenziwa kanjani ukuskena kwe-lung PET?
Ukuskena i-lung PET scan, ufakwa emthanjeni ngenani elincane le-glucose eliqukethe into elandelanayo ngemisebe ye-radio cishe ihora ngaphambi kokuskena. Ngokuvamile kusetshenziswa isotopu ye-element fluorine. Inaliti ingaluma okwesikhashana, kepha uma kungenjalo inqubo ayinabuhlungu.
Uma ususemgudwini wegazi, into elandelanayo iyanqwabelana ezithweni zakho nasezicutshini zakho bese iqala ukukhipha amandla ngendlela yemisebe ye-gamma. Iskena se-PET siyayithola le misebe bese sakha izithombe ezinemininingwane ngayo.Izithombe zingasiza udokotela wakho ukuthi ahlole ukwakheka nokusebenza kwesitho noma indawo ethize ehlolwayo.
Ngesikhathi sokuhlolwa, udinga ukulala phansi etafuleni elincane. Leli thebula ligudla ngaphakathi kwesithwebuli esimise okomhubhe. Uyakwazi ukukhuluma nochwepheshe ngenkathi ukuskena kwenzeka, kepha kubalulekile ukuthi ulale unganyakazi ngenkathi kuthwetshulwa. Ukunyakaza okuningi kungaholela ezithombeni ezifiphele.
Ukuskena kuthatha imizuzu engama-20 kuye kwengama-30.
Ukulungiselela kanjani
Udokotela wakho uzokucela ukuthi ungadli noma uphuze noma yini ngaphandle kwamanzi amahora amaningi ngaphambi kokuskena. Kubaluleke kakhulu ukulandela le miyalo. Ukuskena i-PET kuvame ukuncika ekuqapheleni umehluko omncane wokuthi amaseli agaya kanjani ushukela. Ukudla umthamo noma ukuphuza isiphuzo esinoshukela kungaphazamisa imiphumela.
Lapho ufika, ungacelwa ukuthi ushintshe ugqoke isibhedlela, noma uvunyelwe ukugqoka ezakho izingubo. Uzodinga ukususa noma yiziphi izinto zensimbi emzimbeni wakho, kufaka phakathi ubucwebe.
Tshela udokotela wakho uma uthatha imishanguzo noma izithasiselo. Eminye imishanguzo, njengaleyo yokwelapha isifo sikashukela, ingaphazamisa imiphumela ye-PET scan.
Uma ungakhululekile ezindaweni ezivalekile, udokotela wakho angakunika imithi ezokusiza uphumule. Lesi sidakamizwa kungenzeka sidale ukozela.
Iskena se-PET sisebenzisa inani elincane le-tracer enemisebe. I-tracer enemisebe izosebenza emzimbeni wakho kungakapheli amahora noma izinsuku ezimbalwa. Ekugcineni izophuma emzimbeni wakho ngomchamo nasesitulweni.
Yize ukuvezwa kwemisebe evela kuskena se-PET kukuncane, kufanele wazise udokotela wakho ngaphambi kokwenza noma iyiphi inqubo esebenzisa imisebe uma ukhulelwe noma uncelisa.
Iskena se-Lung PET nesiteji
Ukuskena kwamaphaphu kwe-PET nakho kusetshenziselwa ukufaka umdlavuza wamaphaphu. Izicubu ezinesilinganiso semetabolism ephakeme (ukusetshenziswa kwamandla okuphezulu), njengezicubu zomdlavuza wamaphaphu, zimunca okuningi okulandela umkhondo kunezinye izicubu. Lezi zindawo zivelele kuskena se-PET. Udokotela wakho angasebenzisa imifanekiso enezinhlangothi ezintathu ukuthola izicubu zomdlavuza ezikhulayo.
Izicubu zomdlavuza eziqinile zinikezwa isigaba esiphakathi kuka-0 no-4. Ukulinganisa kusho ukuthi umdlavuza othile usuthuthuke kangakanani. Isibonelo, umdlavuza wesigaba sesi-4 uthuthuke kakhulu, usabalale waqhubekela phambili, futhi imvamisa kunzima kakhulu ukwelashwa kunomdlavuza wesigaba 0 noma 1.
Isiteji sisetshenziselwa ukubikezela ukubonwa. Isibonelo, umuntu othola ukwelashwa lapho etholakala esigabeni 0 noma 1 somdlavuza wamaphaphu kungenzeka aphile isikhathi eside kunomuntu onomdlavuza wesigaba 4.
Udokotela wakho angasebenzisa izithombe ezivela kusikena se-lung PET ukuthola indlela yokwelashwa engcono kakhulu.
