Ingabe udokotela wakho ukutshelile ukuthi wenze i-PET scan? Noma uke wezwa leli gama ndawana thize? Ngemva kokuzwa lokhu, kungenzeka ukuthi uzizwe wesaba futhi unelukuluku. Igama elithi 'PET' yigama elinikezwa isilwane, futhi kungenzeka ukuthi uke wazibuza ukuthi lolu hlobo lwe-PET scan luyini. Ungesabi lutho. Namuhla, sizoxoxa ngokuthi lolu hlobo lwe-PET scan luyini, ukuthi lwenziwa kanjani, nokuthi lusetshenziselwa ini ngendlela elula kakhulu, ngolimi ongaluqonda.
Kalula nje, kuyini i-PET scan?
Igama eliphelele le-PET scan yi -Positron Emission Tomography scan . Kodwa akekho kithi osebenzisa lelo gama elide, libizwa ngokuthi i-PET scan ngamafuphi.
Lokhu futhi kuyindlela ekhethekile yokuhlola ngaphakathi emizimbeni yethu. Kodwa kuhlukile kancane kwezinye izinhlobo zokuskena. Kusinika isithombe sendlela izitho zethu nezicubu ezisebenza ngayo .
Kulolu vivinyo, inani elincane lamakhemikhali aphephile kakhulu, anemisebe lifakwa emzimbeni wakho ngomthambo. Lokhu sikubiza ngokuthi i-radiotracer . Ngemuva kwalokho, kusetshenziswa i-PET scan ukuze kubhekwe ukuthi la makhemikhali ahamba kanjani emzimbeni wakho wonke.
Cabanga ngale ndlela. Amaseli agulayo emizimbeni yethu, ikakhulukazi amaseli omdlavuza, "alambile" kakhulu kunamaseli anempilo. Ukuguqulwa kwawo kwe-metabolism kuyashesha kakhulu. Ngakho-ke lo mshini wokulandelela i-radiotracer esiwunikezayo (ngokuvamile unamathela kushukela), lawo maseli "alambile" agulayo awumunca ngokushesha nangaphezu kwamaseli anempilo. Kufana nezingane ezincane ezidla ushokoledi.
Khona-ke, uma uyibheka ngesithwebuli, izindawo lapho i-radiotracer iqoqene khona kakhulu, zibukeka sengathi “izibani zivuliwe.” Odokotela babiza lezi ngokuthi “izindawo ezishisayo.” Ngokubheka lezo zindawo ezikhanyayo, ungakwazi ukubona ngqo ukuthi kunenkinga kuphi emzimbeni.
Uyini umehluko phakathi kwe-PET scan, i-CT kanye ne-MRI?
Abantu abaningi bayadideka ngalezi zinhlobo ezintathu zokuskena. Zontathu zithatha izithombe zangaphakathi lomzimba. Kodwa indlela lezo zithombe ezithathwa ngayo kanye nolwazi esiluthola kulezo zithombe kuhluke ngokuphelele. Ake sizame ukuqonda lokhu kalula.
| Uhlobo lokuskena | Indlela esebenza ngayo | Yini esiboniswa yona? (Kalula nje) |
|---|---|---|
| I-CT Scan (i-Computed Tomography) | Kusetshenziswa imisebe ye-X. | Ukwakheka komzimba. Kufana nomdwebo wesakhiwo. Kubonisa ukuthi izitho zikuphi, ukuma kwazo, kanye nosayizi wazo. |
| Ukuskena kwe-MRI (Umfanekiso Wokuqabulana Kwamagnetic) | Kusetshenziswa omaginethi abanamandla kanye namagagasi omsakazo. | Inikeza izithombe ezicacile nezinemininingwane zesakhiwo somzimba, ikakhulukazi izicubu ezithambile. |
| Ukuskena kwe-PET (i-Positron Emission Tomography) | Kusetshenziswa into enemisebe (i-Radiotracer). | Umsebenzi womzimba. Kubonisa ukuthi izibani zivuliwe yini ngaphakathi kwesakhiwo, ukuthi abantu bayasebenza yini, nokuthi yiliphi igumbi elisebenza kakhulu. |
Okubaluleke kakhulu, i-PET scan ingathola izinguquko ekusebenzeni kwamaseli esitho ngaphambi kokuba i-CT kanye ne-MRI scan zibonise izinguquko esimweni saso. Lokhu kusho ukuthi i-PET scan inekhono elimangalisayo lokubona isifo kusenesikhathi .
Ngokuvamile, odokotela bazo-oda i -PET-CT scan ukuze bathole izinzuzo zazo zombili izinhlobo zokuskena. Lokhu kusho ukuthi i-PET scan kanye ne-CT scan kwenziwa ngesikhathi esifanayo, emshinini ofanayo. Ngemuva kwalokho singabona kokubili isakhiwo (kusukela ku-CT) kanye nomsebenzi (kusukela ku-PET) womzimba esithombeni esisodwa. Lokhu kusiza kakhulu ekwenzeni ukuxilongwa okunembile kakhulu.
Yiziphi izinhlobo zezifo ezibhekwa yi-PET scan?
I-PET scan ingalinganisa izinqubo ezibalulekile emzimbeni wethu, njengokugeleza kwegazi, ukusetshenziswa komoya-mpilo, kanye nokuguqulwa kwe-glucose ibe yi-metabolism. Ngakho-ke, isetshenziselwa ukuxilonga izimo zezokwelapha ezahlukahlukene.
1. Ngomdlavuza:
Ama-PET scan asetshenziswa kakhulu ekwelapheni umdlavuza.
- Ukuthola umdlavuza:Uma kukhona ukusolakala kokuthi amangqamuzana omdlavuza akhula ndawana thize emzimbeni, i-PET scan iwusizo kakhulu ekuqinisekiseni lokho. Isibonelo, umdlavuza webele, umdlavuza wamaphaphu, umdlavuza we-thyroid, njll.
- Bheka ukuthi umdlavuza ususakazeke yini: Uma umdlavuza usutholakale, ukuhlolwa okukodwa komzimba wonke kungasetshenziswa ukuhlola ukuthi ususakazeke yini (ususakazeke) kwezinye izingxenye zomzimba.
- Bheka ukuthi uyasabela yini ekwelashweni: Ngesikhathi sokwelashwa komdlavuza (isib. i-chemotherapy), kwenziwa ukuhlolwa kwe-PET ukuze kubonakale ukuthi ukwelashwa kuyabulala yini amangqamuzana omdlavuza futhi kunciphisa isimila.
- Hlola ukuthi umdlavuza ubuyile yini: Lokhu kusetshenziselwa nokuqinisekisa ukuthi kukhona yini okusolakala ukuthi umdlavuza ubuyile ngemva kokuba ukwelashwa sekuqediwe.
- Thola umbono wesimo esibikezelayo: Odokotela bangabikezela nokuthi lesi sifo sizoba njani ngokubheka umsebenzi womdlavuza.
2. Ngezinkinga Zenhliziyo:
- Ngemva kokuhlaselwa yinhliziyo, bheka ukuthi umonakalo ongakanani owenzekile emisipheni yenhliziyo.
- Thola ukuthi ukugeleza kwegazi ezingxenyeni ezithile zenhliziyo kunciphile yini nokuthi lezo zingxenye zingazuza yini ngokuhlinzwa kwe -angioplasty noma i-coronary artery bypass .
3. Ngezinkinga Zobuchopho:
- Bona umsebenzi wezimila zobuchopho.
- Ukuthola indawo eqondile ebuchosheni lapho ukuxhuzula kuqala khona kumuntu onesifo sokuxhuzula .
- Thola izinguquko ekusebenzeni kobuchopho ezifweni ezifana ne -dementia kanye nesifo i-Alzheimer's .
Ngingakulungiselela kanjani ukuhlolwa kwe-PET?
Ukuskena kwe-PET kuyindlela yokulaliswa esibhedlela. Lokho kusho ukuthi ungaya ekhaya ngalolo suku. Udokotela wakho uzokunikeza imiyalelo eqondile oyidingayo. Kodwa ngokuvamile, kufanele uqaphele ngalezi zinto.
| Okufanele ngikwenze | Incazelo kanye nesizathu |
|---|---|
| Yazisa ngemithi yakho | Tshela udokotela wakho ngayo yonke imithi, amavithamini, izithasiselo zokudla, kanye nokungezwani komzimba okuthathayo. |
| Ukukhulelwa noma ukuncelisa | Uma ucabanga ukuthi ukhulelwe noma uncelisa, kufanele utshele udokotela wakho nakanjani . |
| Ukuzila ukudla | Ngokuvamile, akufanele udle lutho amahora ayisithupha ngaphambi kokuhlolwa. Ungaphuza amanzi kuphela. Uma unesifo sikashukela, udokotela wakho angase ashintshe lesi seluleko. |
| Gwema i-caffeine. | Uma uzohlolwa inhliziyo, gwema izinto ezifana netiye, ikhofi, kanye noshokoledi amahora angama-24 ngaphambi kokuhlolwa. |
| Izingubo kanye nobucwebe | Gqoka izingubo ezikhululekile nezikhululekile. Susa izinto zensimbi ezifana namacici, imigexo, amasongo, izibuko, kanye namazinyo okufakelwa bese uzishiya ekhaya. |
| Ukwesaba izindawo ezivaliwe | Uma uzizwa ungakhululekile noma wesaba lapho ungena ku-scanner (claustrophobia), tshela udokotela kusenesikhathi. Ungase unikezwe umuthi omncane ukuze uphumule. |
Kwenzekani ngesikhathi sokuskena?
Uma uya ngosuku lokuskena, uzoba nalolu hlobo lwesipiliyoni.
1. Umjovo: Okokuqala, umhlengikazi uzofaka i-radiotracer esikhulume ngayo (ngokuvamile uhlobo olubizwa ngokuthi i-fluorodeoxyglucose (FDG) ) emthanjeni osengalweni yakho. Ngeke uzwe mehluko uma ifakwa.
2. Cishe ihora lokuphumula: Ngemva kwalokho, uzocelwa ukuba uhlale esihlalweni ekamelweni elithule cishe ihora. Lesi sikhathi siyadingeka ukuze umuthi ojoviwe uhambe emzimbeni wonke futhi umunceke ezithweni nasezicutshini ezidingekayo. Kubaluleke kakhulu ukuhlala uzolile phakathi nalesi sikhathi, unganyakazi noma ukhulume kakhulu. Ngoba uma unyakaza kakhulu, i-radiotracer ingamuncwa kakhulu emisipheni, okungathinta imiphumela yeskeni.
3. Kuskena:Ngemva kwehora, uzoyiswa ekamelweni lokuskena. Uzocelwa ukuba ulale etafuleni lokuhlola elixhunywe emshinini wokuskena.
4. Ukuskena: Umbhede ungena kancane kancane kuskena. Umshini ubukeka njengedonathi enkulu. Ucelwa ukuthi uhlale unganyakazi ngaphakathi. Ukunyakaza kungafiphaza izithombe. Ungase uzwe imisindo yokuchofoza nokubhuza emshinini ngenkathi kuskenwa. Yonke inqubo ithatha cishe imizuzu engama-30.
5. Ngemva kokuskena: Ngemva kokuskena sekuqediwe, kuzodingeka ulinde isikhashana ngenkathi uchwepheshe ehlola ukuthi izithombe zicacile yini. Uma konke kulungile, ungaya ekhaya.
Ukuhlolwa konke, okuhlanganisa umjovo, ukuphumula, kanye nokuskena, kuthatha cishe amahora amabili .
Ingabe kukhona izingozi noma imiphumela emibi kulokhu?
Abantu abaningi bayesaba uma bezwa igama elithi 'radioactive', kodwa empeleni i-PET scan iyisivivinyo esiphephile kakhulu.
Inani lezinto ezisebenzisa imisebe esetshenziswa kulokhu lincane kakhulu. Lifana nenani lemisebe esivezwa kuyo ngokwemvelo lapho sihamba ohambweni olude lwendiza. Futhi, lo muthi awuhlali isikhathi eside emzimbeni. Ukhishwa emzimbeni ngomchamo emahoreni ambalwa. Yingakho kunconywa ukuphuza amanzi amaningi ngemva kokuskena ukuze kusize ngalokhu.
Kodwa-ke, kunezimo ezimbalwa ezingavamile lapho ingozi ingavela khona:
- Omama abakhulelwe nabancelisayo: Ukuskena kwe-PET akwenziwa kulezi zimo ngoba imisebe ingaba yingozi embungwini futhi ingadluliselwa enganeni ngobisi lwebele.
- Ukungezwani komzimba: Abanye abantu bangase babe nokungezwani komzimba ne-radiotracer noma idayi yokuqhathanisa esetshenziswa ku-PET-CT scan. Lokhu akuvamile kakhulu. Uma lokhu kwenzeka, ithimba lezokwelapha likulungele ukukwelapha ngokushesha.
- Isifo Sikashukela: Abantu abanesifo sikashukela bangase babe nezinguquko endleleni umzimba omunca ngayo i-radiotracer equkethe ushukela. Lokhu kungathinta imiphumela. Ngakho-ke, uma unesifo sikashukela, udokotela wakho uzokweluleka ngokuthi ungashintsha kanjani ukudla kwakho kanye nemithi ngaphambi kokuhlolwa.
Imiphumela yokuskena ivame ukutholakala zingakapheli amahora angama-24 . Udokotela we-radiologist, oqeqeshwe ngokukhethekile ukufunda izithombe ze-PET scan, uzobuyekeza izithombe, adale umbiko, bese ewuthumela kudokotela wakho. Udokotela uzobe esekuchazela umbiko.
Umlayezo Wokuya Nawe Ekhaya
- I-PET scan ikhombisa ukusebenza kwezitho nezicubu emzimbeni.I-CT noma i-MRI scan ikhombisa isakhiwo sazo.
- Lokhu kuwusizo kakhulu ekutholeni umdlavuza, izifo zenhliziyo, kanye nezifo zobuchopho zisencane kakhulu.
- Lokhu kuhlolwa kuphephile kakhulu . Inani lemisebe esetshenziswayo liphansi kakhulu, futhi lisuswa ngokushesha emzimbeni.
- Landela imiyalelo kadokotela ngokucophelela ngaphambi kokuhlolwa (ikakhulukazi ukuzila ukudla) .
- Uma unemibuzo noma ukukhathazeka mayelana nokuhlolwa, khuluma nodokotela wakho ngakho ngokukhululekile . Uzokuchazela konke.
