I-Positron Ukuphuma kwe-Tomography, okanye ukuhlolwa kwe-PET, kukuvavanya uvavanyo lokubonisa ukubonisa umlinganiselo wezenzo zamaseli kwaye kunceda ukufumanisa iiseli zomhlaza. Uhlobo oluqhelekileyo lwe-PET lokutshekisha olusetyenziswa namhlanje yi-FDG-PET, kwaye lidla ngokusetyenziswa kunye ne-CT, apho imeko ibizwa ngokuba yi-FDG-PET / CT.
Inqaku langoku libhekisela kulolu hlobo lokuskena.
I-PET ihlola ithimba lakho lononophelo lwezempilo ukuze lichanele iindlela zokunyanga ezingcono kwaye uphonononge impendulo yonyango oluye lafumana.
Inqaku, ezinye iintlobo ze-PET zicatshulwa zisetyenziswa. Ngokomzekelo, i-scan ye-DOTATOC ye-PET-CT i-Gallium-68 isetyenziselwa iintlobo ezithile zeengqomzana eziqhelekileyo, ezibizwa ngokuba yi-neuroendocrine tumors. Kuyafaneleka ukuba uqaphele ukuba akuzona zonke i-cancer eziboniswayo kunye ne-FDG-PET-CT.
Zininzi iintlobo eziqhelekileyo ze-lymphoma zingabonwa ngokusetyenziswa kwe-FDG-PET / CT.
I-PET isebenza njani?
Ngethuba lokutshintshwa kwe-FDG-PET, ishukela elityhutyhileyo, okanye i-radiotracer, lwenziwa emzimbeni wakho. Oku kufuthi kwenziwe nge-injection injection, kodwa kwezinye iimeko, unokucelwa ukuba uphuze okanye uphawule i-radiotracer. Iswekile iya kuqokelela kwiifomthi zakho kwaye ibonise amanqanaba omsebenzi weeseli. Ukukhishwa kweemveliso ezivela kwi-tracer kuthathwa ngokusetyenziswa kwezixhobo zokucinga, ukubonelela ngomsebenzi wendlela yokusebenza.
Ekubeni ezinye iintlobo zeeseli zomhlaza zinomlinganiselo ophezulu weetekisi kuneeseli eziqhelekileyo kwaye ngoko zithatha ezinye iishukela zomshukela okhuseleko, oogqirha banokuzichonga ngexabiso le-radiotracer abayithathayo. Kukho iintlobo zeeseli zomhlaza ezinokuthotywa kweeshukela ezingabonakali kwi-SDG-PET yokuhlola.
Ngokwenene, i-FDG-PET iskena iyakwazi ukufumana iiseli zomhlaza esekelwe kwi-sugar sugar.
Yintoni iPET / CT Scan?
I-Tomography yeComputer , okanye i-CT, inako ukubonelela ngolwazi olunzulu malunga nezakhiwo ngaphakathi komzimba wakho. Le mihla, amaziko amanonophelo empilo asebenzisa intsebenziswano ye-PET ne-CT yokufumana imifanekiso echanekileyo nechanekileyo. Ukudibanisa le mvavanyo kunamanani amaninzi:
- Ukutshekisha kwe-PET kubonakalisa iiseli ezingaqhelekanga emzimbeni wakho, kunye ne-CT scan ithetha indawo yawo ngqo
- Ukutshekisha kwe-PET kunokukunceda ukuba i-mass scan ebonwe kwi-CT iqulethe iiseli zomhlaza okanye cha
- I-CT scan ingancedisa ukuba iiseli ezibonisa umsebenzi ophezulu we-PET ukukhangela ii-cells eziqhelekileyo, okanye ukuba zithengi zintsholongwane ezisebenzisa nje ishukela njenge-muscle-like muscle okanye white cells cells
Ukulungiselela Iimviwo Zakho
Ukuze ochwepheshe bakwazi ukufumana imifanekiso echanekileyo, baya kunika ulwazi olunzulu malunga nokulungiselela iPT scan yakho. Ngokuqhelekileyo le miyalelo iya kubonisa ukuba kufuneka uceba uku:
- Ngokukhawuleza (asinanto yokutya) kwiiyure ezingama-4-6 phambi kovavanyo lwakho ukuqinisekisa ukuba iiseli zakho zilambile ngokwaneleyo ukuba zenze i-radiotracer yeshukela. Oku kubandakanya ukungabi nekhofi okanye itiye, i-chewing gum okanye i-candy.
- Phuza kakhulu amanzi amaninzi aqhubela phambili uvavanyo lwakho.
- Thatha amayeza enhlungu xa uwafuna phambi kovavanyo. Uya kufuneka ulale ixesha elide ngexesha lokukhangela kwakho, ngoko uya kufuna ukuqiniseka ukuba nayiphi na into engeyiyo ingxaki ilawulwa ngokwaneleyo ngaphambili.
- Thatha nawaphi na amayeza njengesiqhelo ngosuku lovavanyo lwakho, ngaphandle kwesilwanyana sesifo sikashukela okanye iicrups.
- Ukushiya nayiphi na into yentsimbi efana nezobucwebe, okanye izixhobo zentambo ezisusayo, ekhaya. Ngexesha lokuvavanywa, unokucelwa ukuba ususe ama-glass okanye izixhobo zokuvalelwa ukususela ekubeni isinyithi singaphazamisa imifanekiso.
Kumele uxelele isebe lempilo yonyama ukuba:
- Uye waba ne-biopsy, inkqubo yokuhlinzwa, okanye unyango lwe-radiation kwiintsuku ezili-10 phambi kokuqashwa kwakho kwe-scan
- Ukuphuhlisa intsholongwane nayiphi na uhlobo ngaphambi kokuqeshwa kwakho
- Shintsha ingqondo yakho kwaye unqume ukuba ungaba novavanyo
- Ngaba i-claustrophobic okanye iyathusa kwiindawo ezincinci. Unokudinga imithi yokuxhalabisa okanye yokuxhalabisa ukuze uphucule ngokukhawuleza.
- Ngaba unobungozi okanye ukuphendula kwangaphambili ukuhlula idayi.
- Ngaba unokukhulelwa okanye ukuba uncelisa
- Isifo sikashukela
Yintoni eyenzekayo ngexesha loviwo?
Xa ufika kwi-scan ye-PET, imbali yakho kunye nolwazi luya kuhlaziywa, kwaye uya kuba nethuba lokubuza nayiphi na imibuzo eyongezelelweyo onokuyenza. Unokucelwa ukuba usayine ifomu yokuvuma ngaphambi kokuhlolwa. I-intravenous (IV) ingaqaliswa, ingakumbi ukuba unesicingo se-CT kunye ne-PET scan.
Amazinga egazi le-glucose akho angakhangela ngeli xesha. Ukuba ngaba kunjalo, uya kuba nompopho womunwe, kwaye i-sugar sugars yakho iya kuhlolwa ngokusebenzisa umshini ogcinwe ngesandla obizwa ngokuba yi- glucometer . Ukuba amanqanaba akho aphezulu kakhulu, unokufuna ukuphinda uhlalutye uvavanyo lwakho.
Kule ngongoma, uya kukhululeka kwindawo epholileyo, efudumeleyo, kunye ne-radiotracer iya kulawulwa kuwe. Kungathatha ixesha lokuba i-radiotracer ihambe emzimbeni wakho kwaye iqokelele kwiifisi zakho, ngoko uya kucelwa ukuba ulale okanye uhlale ngokuthula ngeli xesha. Ngokuxhomekeka kwimihlaba yomzimba wakho, kunye nezikhokelo ezilandelwa liziko lakho lononophelo lwempilo, unokucelwa ukuba ungafundi, ulalele umculo, okanye ukhulume ukuze uphephe konke ukuhamba.
Xa ixesha lifika, uya kulala etafileni ehambayo ehambisa i-slayer-like likener. Uzakufuna ukube usaphila ngexesha lokuskena; ngokuqhelekileyo kuthatha imizuzu engama-20 ukuya kwimizuzu engama-60 yovavanyo lwe-PET kunye ne-CT.
Abachwephesha baya kuqinisekisa ukuba banemifanekiso ababeyifunayo, kwaye ukuba kunjalo, baya kususa indawo yakho ye-IV kwaye uya kukhululeka ukushiya ukulandela uvavanyo. Ukuba uthathe isondlo ngaphambi kokuskena, kungenakugqithiswa, ngoko kuya kufuneka ube nomnye umntu ekuqhubela ekhaya.
Konke, kufuneka ulindele ukuba ube kwisebe lokucinga ngehora eli-2, ukususela ekuqaleni ukuya ekupheleni.
Emva koviwo
Emva kokuba uvavanyo lwePET luphelile, uya kuba nokutya nokusela. Enyanisweni, ukusela amaninzi amanzi ukucetyiswa ukukunceda ukucima i-radiotracer kwindlela yakho. Isixa semirhumo oya kufumana ngexesha lokutshekisha kwe-PET kufana ne-CT okanye ye- bone scan .
Lo mzabalazo uza kulahlekelwa ngumsebenzi wakho emzimbeni wakho kwaye unokugqithiswa kwisigxina sakho kunye / okanye umchamo kwiiyure ezilandelayo ukulandelwa kwe-PET yakho. Ezinye iimithombo zincoma ukuhlala kude neentsana okanye abafazi abakhulelweyo ngeeyure ezimbalwa emva kokuba ushiye. I-radiotracer kufuneka iphume ngokupheleleyo kwinkqubo yakho emva komhla okanye njalo.
Iingcali zonyango lwenyukliya ziza kuhlolisisa imifanekiso evela kwi-scan yakho, kwaye ithumele ukutolika kwayo kumgqirha wakho othethayo. Buza ukuba unokuqhagamshelana nogqirha wakho kwiziphumo, okanye ukuba baya kuqhagamshelana nawe.
Ukuqulunqa
I-PET i-scans iyakwazi ukufumana iiseli ezingaqhelekanga nje ngendlela abayifumayo kunye ne-metabolize ushukela. Ingakumbi xa zisetyenziselwa ukudibanisa ne-CT scan, i-PET scan ingakhangela iinkcukacha ezichanekileyo malunga neekliniki ezifana ne-lymphoma kunye ne-myeloma, kwaye uncede oogqirha bacwangcise baze bahlole unyango.
Ngaphambi kokukhangela kwe-PET yakho, qiniseka ukuba unikezwe, kwaye uyaqonda, yonke imiyalelo enikwe yona ukukunceda ukulungiselela.
