Udokotela wakho kungenzeka ukuthi ukweluleke ukuthi wenze i-PET scan. Abanye abantu bayesaba kancane igama elithi 'scan' uma besho lokho. Kodwa empeleni akukho okufanele ukwesabe. Lobu ubuchwepheshe obuthuthukisiwe kakhulu obusisiza sibone kahle ukuthi kwenzekani emizimbeni yethu nokuthi izifo ziqhubeka kanjani. Ake sixoxe ngokuthi kuyini, kwenziwa kanjani, nokuthi kufanele yini sikwesabe.
Yini ngempela eyenziwa yi-PET scan?
Kalula nje, i-PET scan iyisivivinyo esikhethekile esibheka ukuthi izitho nezicubu zomzimba wethu zisebenza kanjani. Ihlukile kwi-X-ray, i-CT noma i-MRI scan, ngoba ezinye iziskeni zibonisa izithombe zangaphakathi komzimba kuphela. Kodwa-ke, i-PET scan ingabona nokuthi amaseli ethu asebenza kahle kangakanani. Ngaphambi kokwenza lokhu kuhlolwa, udokotela uzofaka
into enemisebe (ebizwa ngokuthi i-'radiotracer' noma i-'tracer') emzimbeni wakho. Lokhu kufana nomuthi okhethekile. Ungesabi, ngeke kulimaze umzimba. Ngemuva kwalokho umshini we-PET scan ungathola ukuthi le nto ihamba kanjani emzimbeni nokuthi iqongelela kuphi. Uma le nto iqongelela endaweni ethile, kungaba uphawu lwesifo. Cabanga ngalo mshini we-PET scan njenge-donut enkulu. Umbhede uhamba phakathi kwawo. Uthunyelwa ukuyohlolwa ulele embhedeni. Lo mshini awuvaliwe ngokuphelele njengomshini we-MRI, ngakho abantu abaningi abazizwa bevalelekile.
Yiziphi izindlela zokusebenzisa i-PET scan?
Odokotela basebenzisa i-PET scan ngokuyinhloko ukuze bathole izifo, balungiselele ukuhlinzwa, futhi babone ukuthi ukwelashwa kusebenza kahle kangakanani. Ivame ukusetshenziswa kakhulu kumdlavuza, izifo zenhliziyo, kanye nezifo zobuchopho.
Ngomdlavuza
Amaseli omzimba wethu adinga amandla ukuze asebenze. Amaseli omdlavuza awuhlobo lweseli elisebenzisa amandla amaningi kunamaseli avamile. I-PET scan ingabona lokhu kusetshenziswa kwamandla aphezulu. Bese kuthi, esithombeni sokuskena, izindawo lapho amaseli omdlavuza ebonakala khona
njengamabala akhanyayo . I-PET scan ivame ukubona umdlavuza ngaphambi kokuba ezinye izivivinyo zikwazi. Futhi,
- Bheka ukuthi umdlavuza ususakazekele kwezinye izingxenye zomzimba.
- Thola ukuthi ukwelashwa kwamanje kuyasebenza yini.
- Hlola ukuthi umdlavuza ubuyile yini ngemva kokwelashwa.
Ngesifo Senhliziyo
Ukuskena kwe-PET kungabonisa ukuthi inhliziyo yakho isebenza kahle kangakanani. Uma i-'tracer' eshiwo ngenhla ifakwa emzimbeni wakho, iya enhliziyweni yakho negazi lakho. Ukuskena kukhombisa ukuthi lingakanani igazi elifika ezingxenyeni ezahlukene zenhliziyo yakho. Uma ingxenye ingatholi igazi elanele, kungabonisa inkinga, njengokuvimba komthambo wenhliziyo. Kusetshenziswa futhi ukubheka umonakalo enhliziyweni ngemva kokuhlaselwa yinhliziyo.
Ngezimo Zobuchopho
Ukuskena kwe-PET kungasiza futhi ekuxilongeni izimo ezahlukahlukene ezihlobene nobuchopho. Isibonelo:
Uyini umehluko phakathi kwe-PET, CT, kanye ne-MRI scans?
Kunokudideka okukhulu phakathi kwabantu mayelana nalezi zinhlobo ezintathu zokuskena. Ake siqonde lo mehluko etafuleni elilula.
| Uhlobo lokuskena | Indlela esebenza ngayo | Kubonisani? |
|---|
| Ukuskena kwezilwane ezifuywayo | Umsebenzi weseli ulinganiswa kusetshenziswa into enemisebe (i-tracer). | Kubonisa indlela izitho nezicubu ezisebenza ngayo . Umsebenzi wamaseli anesifo ungabonakala. |
| I-CT Scan | Ama-X-ray asetshenziselwa ukuthatha izithombe zomzimba ezihlukanisa izingxenye zomzimba. | Ibonisa isakhiwo nesimo samathambo, imithambo yegazi, kanye nezicubu ezithambile. |
| Iskeni se-MRI | Izithombe zithathwa kusetshenziswa omaginethi abanamandla kanye namagagasi omsakazo. | Ibonisa isakhiwo esicacile nesinemininingwane sezinto ezifana nezitho zomzimba, izicubu zomzimba kanye nomgogodla. |
Kalula nje, i-CT ne- MRIKufana nokuthatha 'isithombe' sengaphakathi lomzimba. Kodwa i-PET scan ifana nokuthatha ividiyo yokuthi leso sitho 'sisebenza' kanjani.
Ngenxa yalesi sizathu, abanye odokotela basebenzisa ama-hybrid scan abizwa ngokuthi i-PET/CT noma i-PET/MRI. Lawa ma-scans angabheka kokubili isakhiwo kanye nomsebenzi womzimba ngokuskena okukodwa, ngakho imiphumela inembe kakhudlwana.
Ulungiselela kanjani ngaphambi kokuskena?
Kunezinto ezimbalwa okudingeka uzilungiselele ngaphambi kokuhlolwa kwe-PET. Ukulandela lezi zinyathelo kubaluleke kakhulu ukuze uthole imiphumela enembile.
Okokuqala, tshela udokotela wakho lezi zinto:
- Ukungezwani komzimba : Qiniseka ukuthi usitshela uma unesifo sokungezwani komzimba, ikakhulukazi uma uqhathanisa umbala, i-iodine , noma ukudla kwasolwandle.
- Ezinye izimo zezokwelapha: Uma unesifo sikashukela , sicela usazise ngaso.
- Imithi oyithathayo: Tshela udokotela wakho ngayo yonke imithi, amavithamini, kanye nemikhiqizo yamakhambi oyithathayo.
Uma ungowesifazane, qaphela kakhulu ngalokhu:
- Uma ungumama oncelisayo: Ngeke ukwazi ukuncelisa ingane yakho kuze kube yilapho i-tracer isiphelile ngokuphelele emzimbeni wakho. Ngakho-ke, kuzodingeka ukhiphe ubisi lwakho bese ulususa. Khuluma nodokotela wakho ukuze uthole ukuthi kufanele ugweme ukuncelisa isikhathi esingakanani.
- Uma ukhulelwe noma usola ukuthi ukhulelwe: Lokhu kubaluleke kakhulu . Izinto ezisebenzisa imisebe ezisetshenziswa ekuhlolweni zingalimaza ingane. Ngakho-ke yazisa udokotela wakho ngalokhu bese ukhuluma ngenketho engcono kakhulu.
Izinto okufanele uzilandele ngosuku olungaphambi kokuskena:
- Ungazivocavoci umzimba onzima amahora angama-24 ngaphambi kokuhlolwa.
- Ungadli noma uphuze lutho ngaphandle kwamanzi amahora ambalwa ngaphambi kokuhlolwa.
- Susa zonke izinto zokuhloba zensimbi emzimbeni wakho, njengezindandatho, imigexo, namasongo.
Indlela i-PET scan eyenziwa ngayo
Nakuba kunezinguquko ezincane kuye ngokuthi kwenziwa kuphi nokuthi kungani kwenziwa ukuskena, ngokuvamile kuba kanje: 1. Uzocelwa ukuthi ugqoke ingubo yasesibhedlela. 2. Uzonikezwa ithuba lokuya endlini yangasese ngaphambi kokuskena. 3. Ngemuva kwalokho kuzofakwa i-tracer emzimbeni wakho. Lokhu kunganikezwa njengomjovo, njengephilisi, noma njengegesi oyiphefumulayo. 4. Kuzodingeka ulinde
imizuzu engama-30 kuya kwengama-60 ukuze i-tracer ingene emzimbeni wakho ngokuphelele. 5. Uzobe usulala embhedeni wesikena.
Unganyakazi noma ukhulume ngesikhathi sokuskena.Kuzodingeka uhlale uthule kakhulu. Lokhu kungathatha cishe imizuzu engama-30-60. Ungase uzwe umsindo wokubhonga nokuchofoza ovela emshinini ngenkathi kwenziwa iskeni. Lokhu ukuhlolwa okungenabuhlungu. Kodwa-ke, abanye abantu bangase babe nobuhlungu emizimbeni yabo uma behlala endaweni efanayo isikhathi eside.
Ngemva kokuskena, phuza amanzi amaningi ukuze usize i-tracer iphume emzimbeni wakho ngokushesha. Futhi, njengoba umzimba wakho uzoba ne-radioactivity encane amahora ambalwa, udokotela weluleka abesifazane abakhulelwe, izingane ezincane, kanye nezinsana ukuba bagweme ukusondela kakhulu phakathi naleso sikhathi.
Ingabe zikhona izingozi noma imiphumela emibi?
Ukuskena kwe-PET ngokuvamile kuyindlela yokuhlola ephephile kakhulu, kodwa kunezingozi ezithile kanye nokungakhululeki okungase kwenzeke.
- Abantu abane- claustrophobia (ukwesaba izikhala ezivalekile) bangase bakuthole kunzima ukuba ngaphakathi komshini. Kodwa-ke, udokotela wakho angakunika umuthi wokukugcina uzolile ngezikhathi ezinjalo.
- Uma umuntu onesifo sikashukela engalawuli amazinga kashukela egazini lakhe, imiphumela yokuhlolwa ingase ingabi yinembile.
- Kungase kube nobuhlungu noma ukubomvu lapho kufakwe khona i-tracer.
- Akuvamile kakhulu ukuthi kube nokusabela kokungezwani komzimba ku-tracer, kodwa ngokuvamile kuba kuncane.
- Futhi, ukuhlolwa kwe-PET ngeke kwenziwe kumama okhulelwe noma oncelisayo.
Ake sazi ngemiphumela.
Uma imiphumela ye-PET scan ibuya, izindawo ezinomsebenzi omkhulu wamaseli zibonakala njengezindawo ezikhanyayo. Lokhu kungaba uphawu lwesifo.
Kodwa-ke, kubalulekile ukuqaphela ukuthi umphumela omuhle ku-PET scan awusho njalo ukuthi kukhona umdlavuza. Kungaba futhi ukutheleleka, ukuvuvukala, noma iqhubu elingelona umdlavuza. Futhi, uma usanda kuhlinzwa, ukwelashwa ngamakhemikhali, noma ngemisebe, lokho kungathinta imiphumela. Ngakho-ke, ungakhathazeki kakhulu ukuthola isithombe esiphelele salokho okushiwo imiphumela uma uyithola. Udokotela wakho uzoqhathanisa imiphumela neminye imibiko yokuhlolwa, a-ode ukuhlolwa okwengeziwe uma kudingeka, futhi akuchazele konke.
Umlayezo Wokuya Nawe Ekhaya
- I-PET scan ayibheki nje kuphela izitho zomzimba, ibheka nendlela ezisebenza ngayo . Lokhu kubaluleke kakhulu ekuxilongeni umdlavuza, izifo zenhliziyo, kanye nezifo zobuchopho.
- Ngokuvamile lokhu kuyindlela yokuhlola ephephile, kodwa qiniseka ukuthi utshela udokotela wakho uma ukhulelwe, uncelisa, unesifo sikashukela, noma unezinye izifo ezibangelwa ukungezwani komzimba .
- Landela imiyalelo enikezwe ngaphambi kokuhlolwa ngqo (njengokuzila ukudla nokungawuvivinyi umzimba).
- Ukuthi nje kuvela indawo ekhanyayo esikeni akusho ukuthi umdlavuza. Ungakhathazeki ngakho, khuluma nodokotela wakho ukuze uthole ulwazi olufanele.
- Ngemva kokuhlolwa, phuza amanzi amaningi bese ulandela imiyalelo kadokotela.
