Ngaba ugqirha wakho ukuxelele ukuba wenze i-PET scan? Okanye ukhe waliva eli gama ndaweni ithile? Emva kokuva oku, usenokuba uzive usoyika kwaye unomdla. Igama elithi 'PET' ligama elinikwa isilwanyana, kwaye usenokuba uzibuze ukuba loluphi uhlobo lwe-scan olu. Musa ukoyika nantoni na. Namhlanje, siza kuthetha ngokuba yintoni le PET scan, yenziwa njani, kwaye isetyenziselwa ntoni ngendlela elula kakhulu, ngolwimi onokuluqonda.
Ngamafutshane, yintoni i-PET scan?
Igama elipheleleyo le-PET scan yi- Positron Emission Tomography scan . Kodwa akukho namnye kuthi osebenzisa elo gama lide, libizwa ngokuba yi-PET scan ngamafutshane.
Olu luvavanyo olukhethekileyo olusetyenziswa ukujonga ngaphakathi emizimbeni yethu. Kodwa lwahlukile kancinci kwezinye iintlobo zeeskeni. Lusinika umfanekiso wendlela amalungu ethu kunye nezicubu zethu ezisebenza ngayo .
Kolu vavanyo, kufakwa ikhemikhali encinci ekhuselekileyo nene-radioactive emzimbeni wakho ngemithambo yegazi. Oku sikubiza ngokuba yi-radiotracer . Emva koko, kusetyenziswa i-PET scan ukujonga indlela le khemikhali ehamba ngayo emzimbeni wakho.
Cinga ngale ndlela. Iiseli ezinesifo emizimbeni yethu, ingakumbi iiseli zomhlaza, "zilambile" kakhulu kuneeseli eziphilileyo. Umetabolism yazo ikhawuleza kakhulu. Ngoko ke le radiotracer esiyinikayo (idla ngokunamathela kwiswekile), ezo seli "zilambileyo" ziyifumana ngokukhawuleza nangaphezu kweeseli eziphilileyo. Kufana nabantwana abancinci abatya itshokholethi.
Emva koko, xa uyijonga ngeskena, iindawo apho i-radiotracer iqokelele khona kakhulu, zibonakala ngathi “izibane zivuliwe.” Oogqirha bakwabiza ezi “indawo ezishushu.” Ngokujonga ezo ndawo zikhanyayo, unokuchonga ngqo apho kukho ingxaki emzimbeni.
Yintoni umahluko phakathi kwe-PET scan, i-CT kunye ne-MRI?
Abantu abaninzi bayadideka malunga nezi ntlobo zintathu zeskeni. Zontathu zithatha imifanekiso yangaphakathi yomzimba. Kodwa indlela ezithathwa ngayo ezo mifanekiso kunye nolwazi esilufumanayo kwezo mifanekiso zahlukile ngokupheleleyo. Masizame ukukuqonda oku ngokulula.
| Uhlobo lokuskena | Ingaba isebenza kanjani | Siboniswa ntoni? (Kalula nje) |
|---|---|---|
| I-CT Scan (i-Computed Tomography) | Kusetyenziswa ii-X-reyi. | Ulwakhiwo lomzimba. Lufana nomzobo wesakhiwo. Lubonisa apho amalungu akhoyo, imilo yawo, kunye nobukhulu bawo. |
| Iskeni se-MRI (Umfanekiso weMagnetic Resonance) | Kusetyenziswa iimagnethi ezinamandla kunye namaza erediyo. | Inika imifanekiso ecacileyo neneenkcukacha ngesakhiwo somzimba, ingakumbi izicubu ezithambileyo. |
| Iskeni yePET (iPositron Emission Tomography) | Kusetyenziswa into enemisebe (iRadiotracer). | Umsebenzi womzimba. Ibonisa ukuba izibane zivuliwe na ngaphakathi kwisakhiwo, ukuba abantu bayasebenza na, kwaye leliphi igumbi elisebenza kakhulu. |
Okubaluleke kakhulu, i-PET scan inokubona utshintsho kumsebenzi weseli welungu ngaphambi kokuba i-CT kunye ne-MRI scans zibonise utshintsho kwimo yalo. Oku kuthetha ukuba i-PET scans inamandla amangalisayo okubona isifo kwasekuqaleni .
Rhoqo, oogqirha baya ku-odola i -PET-CT scan ukuze bafumane iingenelo zazo zombini ezi ntlobo ze-scan. Oku kuthetha ukuba i-PET scan kunye ne-CT scan zenziwa ngaxeshanye, kumatshini omnye. Emva koko singabona zombini ulwakhiwo (kwi-CT) kunye nomsebenzi (kwi-PET) womzimba kumfanekiso omnye. Oku kunceda kakhulu ekwenzeni uxilongo oluchanekileyo.
Zeziphi izifo ezijongwa yi-PET scan?
I-PET scan inokulinganisa iinkqubo ezibalulekileyo emzimbeni wethu, ezinje ngokuhamba kwegazi, ukusetyenziswa kweoksijini, kunye ne-metabolism yeglucose. Ke ngoko, isetyenziselwa ukuxilonga iimeko ezahlukeneyo zonyango.
1. Ngomhlaza:
Ii-PET scans zisetyenziswa kakhulu kumhlaza.
- Ukufumanisa umhlaza:Ukuba kukho ukurhanelwa kokuba kukho iiseli zomhlaza ezikhula ndaweni ithile emzimbeni, i-PET scan iluncedo kakhulu ukuqinisekisa oko. Umzekelo, umhlaza webele, umhlaza wemiphunga, umhlaza we-thyroid, njl.
- Jonga ukuba umhlaza usasazekile na: Wakuba ufunyenwe umhlaza, iskeni esinye somzimba wonke singasetyenziselwa ukujonga ukuba usasazekile na (usasazekile) kwezinye iindawo zomzimba.
- Jonga ukuba uyasabela na kunyango: Ngexesha lonyango lomhlaza (umz. i-chemotherapy), kwenziwa ii-PET scans ukuze kubonwe ukuba unyango lubulala iiseli zomhlaza kwaye lunciphisa ithumba.
- Jonga ukuba umhlaza ubuyile na: Oku kukwasetyenziselwa ukuqinisekisa ukuba kukho nakuphi na ukurhaneleka kokuba umhlaza ubuyile emva kokuba unyango lugqityiwe.
- Fumana umbono wesifo: Oogqirha banokuqikelela ukuba esi sifo siza kuba njani ngokujonga indlela esisebenza ngayo umhlaza.
2. Ngeengxaki zentliziyo:
- Emva kokuhlaselwa yintliziyo, jonga ukuba ingakanani na umonakalo owenziweyo kwimisipha yentliziyo.
- Qinisekisa ukuba ukuhamba kwegazi kwiindawo ezithile zentliziyo kunciphile na kwaye ingaba ezo ndawo zingancedakala na ngotyando lwe-angioplasty okanye lwe-coronary artery bypass .
3. Ngeengxaki zobuchopho:
- Jonga umsebenzi weethumba zobuchopho.
- Ukufumana indawo echanekileyo engqondweni apho ukuxhuzula kuqala khona kumntu onesifo sokuxhuzula .
- Chonga utshintsho ekusebenzeni kwengqondo kwizifo ezifana ne -dementia kunye nesifo se-Alzheimer .
Ndingayilungiselela njani i-PET scan?
I-PET scan yinkqubo yokunyanga ngaphandle kwesibhedlele. Oko kuthetha ukuba ungaya ekhaya ngaloo mini inye. Ugqirha wakho uza kukunika imiyalelo echanekileyo oyifunayo. Kodwa ngokubanzi, kufuneka uzilumkele ezi zinto.
| Kwenziwe ntoni | Inkcazo kunye nesizathu |
|---|---|
| Yazisa ngamayeza akho | Xelela ugqirha wakho ngazo zonke amayeza, iivithamini, izongezo, kunye nee-allergies ozisebenzisayo. |
| Ukukhulelwa okanye ukuncancisa | Ukuba ucinga ukuba ukhulelwe okanye uyancancisa, ngokuqinisekileyo kufuneka uxelele ugqirha wakho. |
| Ukuzila ukutya | Ngokwesiqhelo, akufanele utye nto iiyure ezi-6 ngaphambi kovavanyo. Ungasela amanzi kuphela. Ukuba unesifo seswekile, ugqirha wakho angatshintsha eli cebiso. |
| Ziphephe i-caffeine. | Ukuba uza kwenza uvavanyo lwentliziyo, ziphephe izinto ezifana neti, ikofu, kunye netshokholethi iiyure ezingama-24 ngaphambi kovavanyo. |
| Impahla kunye nobucwebe | Nxiba impahla ekhululekileyo nekhululekileyo. Susa izinto zesinyithi ezifana namacici, imigexo, izacholo, iiglasi, kunye namazinyo okufakelwa uze uzishiye ekhaya. |
| Uloyiko lweendawo ezivaliweyo | Ukuba uziva ungakhululekanga okanye uyoyika xa usiya kwiskena (claustrophobia), xelela ugqirha kwangaphambili. Usenokunikwa iyeza elincinci ukuze uphumle. |
Kwenzeka ntoni ngexesha leskeni?
Xa usiya ngomhla wokuskena, uya kuba namava alolu hlobo.
1. Inaliti: Okokuqala, umongikazi uza kufaka inaliti ye-radiotracer esithethe ngayo (edla ngokuba yi -fluorodeoxyglucose (FDG) ) emthanjeni osengalweni yakho. Awuyi kuva mahluko xa ifakwa.
2. Malunga neyure yokuphumla: Emva koko, uza kucelwa ukuba uhlale esitulweni kwigumbi elithuleyo kangangeyure. Eli xesha liyadingeka ukuze iyeza elifakwe kwi-injection lihambe emzimbeni wonke kwaye lifunxwe kumalungu nakwizicubu ezifunekayo. Kubaluleke kakhulu ukuhlala uzolile ngeli xesha, ungashukumi okanye uthethe kakhulu. Kuba ukuba ushukuma kakhulu, i-radiotracer inokufunxwa ngakumbi kwizihlunu, nto leyo enokuchaphazela iziphumo ze-scan.
3. Kwiskena:Emva kweyure, uza kusiwa kwigumbi lokuskena. Uza kucelwa ukuba ulale etafileni yovavanyo eqhagamshelwe kumatshini wokuskena.
4. Ukuskena: Ibhedi ingena kancinci kancinci kwiskena. Umatshini ujongeka njengedonathi enkulu. Ucelwa ukuba uhlale ungashukumi ngaphakathi. Ukuhambahamba kunokwenza imifanekiso ingabonakali. Usenokuva izandi zokucofa nokubhuza kumatshini ngelixa iskena sisenziwa. Yonke le nkqubo ithatha malunga nemizuzu engama-30.
5. Emva kokuskena: Emva kokuba ukuskena kugqityiwe, kuya kufuneka ulinde ixesha elithile ngelixa ingcali ihlola ukuba imifanekiso icacile na. Ukuba yonke into ilungile, ungagoduka.
Lonke uvavanyo, kuquka ukujova, ukuphumla, kunye nokuskena, kuthatha malunga neeyure ezimbini .
Ngaba kukho naziphi na iingozi okanye iziphumo ebezingalindelekanga koku?
Abantu abaninzi bayoyika xa besiva igama elithi 'radioactive', kodwa i-PET scan ngokwenene luvavanyo olukhuselekileyo.
Ubungakanani bezinto ezisebenzisa i-radioactive ezisetyenziswa koku buncinci kakhulu. Bufana nobungakanani be-radiation esidibana nayo ngokwemvelo xa sihamba uhambo olude ngenqwelo moya. Kwakhona, eli yeza alihlali emzimbeni ixesha elide. Likhutshwa emzimbeni ngomchamo kwiiyure ezimbalwa. Yiyo loo nto kucetyiswa ukuba usele amanzi amaninzi emva kokuhlolwa ukuze kuncedwe koku.
Nangona kunjalo, kukho iimeko ezimbalwa ezingaqhelekanga apho kunokuvela khona umngcipheko:
- Oomama abakhulelweyo nabancancisayo: Ii-PET scan azenziwanga kwezi meko kuba imitha inokuba yingozi kumntwana ongekazalwa kwaye inokudluliselwa kumntwana ngobisi lwebele.
- Ii-Allergies: Abanye abantu banokuba ne-allergy kwi-radiotracer okanye idayi yokwahlulahlula esetyenziswa kwi-PET-CT scan. Oku kunqabile kakhulu. Ukuba oku kuyenzeka, iqela lezonyango likulungele ukukunyanga ngoko nangoko.
- Isifo seswekile: Abantu abanesifo seswekile banokuba notshintsho kwindlela umzimba ofunxa ngayo i-radiotracer equlethe iswekile. Oku kunokuchaphazela iziphumo. Ke ngoko, ukuba unesifo seswekile, ugqirha wakho uya kukucebisa ngendlela yokutshintsha ukutya kwakho kunye namayeza ngaphambi kovavanyo.
Iziphumo zeskeni zihlala zifumaneka kwiiyure ezingama-24 . Ingcali ye-radiology, eqeqeshwe ngokukodwa ukufunda imifanekiso ye-PET scan, iya kuhlola imifanekiso, yenze ingxelo, ize iyithumele kugqirha wakho. Ugqirha uya kukuchazela ingxelo.
Umyalezo Wokuya Ekhaya
