Umhlaza Indlela yakutshanje diagnostic. I engcolisayo Itomography. Pet scan

I ifezekiswe ngekhompyutha Itomography, okanye PET CT - isifundo ngamalungu angaphakathi abantu radioisotope kokuxilongwa. Pet scan ukwabizwa ngokuba photon-ezimbini amadlozi Itomography, ngenxa yokuba le ndlela isekelwe ekufumanekeni isibini gamma-ray.

Benaso i indlela phambili moshilongo yokuqala umhlaza, igazi kunye nezifo luvo. Xa Oncology Pet isetyenziselwa uxilongo yamathumba yingozi, Ukudlulela khangela ekude kunye nokuhlola unyango.

I mhlobo Itomography luphawulwa ukuchaneka eliphezulu uphando, sesichengeni sosasazeko lwemitha ubuncinane ukuya umzimba, ithuba lokujongisisa zonke ngokwamalungu kutyelelo olunye. Uphononongo kukodwa elula ngokupheleleyo.

Pet, ngokungafaniyo naziphi na ezinye iindlela zophando, wafundela ukuba amalungu yokwakheka nezihlunu, kunye neenkqubo amachiza kwenzeka kuzo. Xa Oncology zitshintshiwe iinkqubo yemichiza, oku kubonwa njengento ukutshintsha umbala kunye okhaliswa inkqubo, yahlukile kwisiqhelo.

Ngenxa yoko, ngenxa yokuba PET bona inkqubo Umhlaza ukuqalwa ixesha elide phambi kokuba thumba kwakhiwa. Ultrasound, CT, MRI uyakwazi ukubona ingxaki kuphela xa nethumba sele wabonakala yaye bafikelela ubukhulu ethile (ukuba izixhobo MRI mihla milimitha hayi ngaphantsi kwe-1-2).

Kwakhona Pet kuya kunceda ukuqinisekisa linobuhlungu okanye nabungozi nethumba, nto leyo ibaluleke kakhulu xa kungekho kungenzeka ukufumana izinto biopsy.

Pet ibona igazi kuqukuqela ancedisana nokusetyenziswa inyama glucose neoksijini. emzimbeni wakhe ifakwe isixa esithile iziyobisi radioactive (iswekile radioactive). Le imisebe glucose radioactive abhalwe vuavanyisi eyodwa sifaka zonke iinkcukacha kwi-computer. Iinkqubo computer kwaye obonisa oko.

Iiseli ne nethe okwandileyo kudla iswekile yegazi eninzi. Yiyo le eyahlukileyo iiseli yomhlaza eziqhelekileyo. Umthombo radioactive okungakumbi kuthinjwa izihlunu, kokukhona baya kubona umfanekiso ngenxa. amacandelo Loo maKristu abizwa ngokuba 'ashushu ". Kwelinye icala, ukuba incinane imveliso kwikhompyutha - umfanekiso nokuvula umbane eziluzizi ifunyenwe zebali ezo zibizwa ngokuba "iqhosha lokulayita".

Yokucolwa e yamathumba angendawo iphezulu kakhulu kunaleyo kwizihlunu esempilweni. Ngoko ke, yamathumba amabi ukuvelisa luphuhle, picture "ashushu".

Wona glucose radioactive ibola ngaphantsi kwe ngemini kwaye lupheliswe ngokupheleleyo emzimbeni.

Ngenxa yokuba PET ukufunda ivale umzimba wonke uphela, Unako ukwenza isicwangciso sokusebenza kakhulu esibanzi. Oku kuza kususa zonke izihlunu zizifo, ukuba kunokwenzeka kwimeko nganye. Yiyiphi ke ziyakwehlisa ngokubonakalayo amathuba okuba ukuhluleka ngakumbi.

Ukusebenzisa Pet ngokuchanileyo walungela somhlaza, yabona, nokuba iindawo nkovu nibethwe phambi kokuba baqala ukwandisa. Oku kwenza kube lula ukuba isicelo uthomalaliso anti-umhlaza kakhulu ngempumelelo ngakumbi.

Ekupheleni ichemotherapy kunye nonyango radiation PET ukujonga ukusebenza kwale unyango.

Pet scan lobutyhila metastases xa ezinye iindlela zokuxilonga zingenako okwangoku ukwenza njalo.

Ngokomzekelo, isifundo bokukhanya ngoncedo lwe X-ray kwimeko isizathu kukhuhlwe kuphela urhano lobukho metastases. Qinisekisa phambi kwabo ungakwazi noba traumatic izihlunu okuhlatywa okanye PET, kodwa scan PET liya kugqiba ubungakanani Ukudlulela yaye uyakuqonda ukunwenwa ziiseli zomhlaza kwi zigaba zokuqala zesi sifo.

Ngokungafaniyo scintigraphy, naye usebenzisa umfanekiso radioisotopes xa entlandlo-ntathu yokufunda PET yenza ukuba uhlolo echanileyo ngakumbi umfanekiso sifo.

Uphononongo kukodwa malunga elibizwa: isigulane ulala phantsi esofeni, nto leyo zityhalelwa kulo matshini. Iyunithi ngokwayo ikhangeleka tube elifutshane. Le nkqubo ihlala phakathi sisiqingatha seyure. Ngaphambi koko, isigulana ifumana inhalation okanye butofelwe elungiselelwe ngokukodwa ichiza eqhumayo.

Izimo for bit Itomography i engcolisayo. Pet scan contraindicated ngayo abasetyhini abakhulelweyo kunye phindeke, kwakunye nezo izigulane ezingakwaziyo ukuzola, kungekho nayiphi na intshukumo, hlalani ebhedini ixesha efunekayo uphando.

I mhlobo Itomography - uphando imali eninzi kakhulu. Kubiza engange 50 000. ERashiya, izixhobo ukuba isifundo esinjalo kuphela kwizixeko ezikhulu.

Kakade ke, loo nto ayenzi ingqiqo ukuqhuba PET ukuvavanya njenge iimviwo zifo umntu esempilweni. Akwanelanga ukuba uhlalutyo rhoqo zabamakishi ithumba.

Ukuba ngemvelo metastasizes ithumba kade, nayo kule meko sinakho avalele ngokwethu oncomarkers okanye ezinye iimvavanyo kwaye rhoqo axilongwe kwi somdlavuza.

Ukuba Ithumba isusiwe kwi zigaba mva futhi kuyaphela iyakhula ngokukhawuleza, ngoko iyavakala ukuqhuba isifundo PET. Nangona iindleko ezibonakala eziphezulu kuphononongo isigulane amamkela ngenxa yonke mfanekiso ezazisenzeka utshintsho emzimbeni wakhe. Ngokusekelwe kule, ugqirha unakho ukukhetha indlela kakuhle yaye ngaloo ndlela ibiza ngaphantsi zonyango.

amayeza Pet scan ngamaxabiso ngoku, kwiimeko ezininzi, kuthengwa ngokwayo kwaye igcina iindleko iziyobisi mkhulu kakhulu isifundo iindleko ngokwayo. Ukongeza, iinkqubo ithumba kukufundisisa PET iza kuzifumanekele kwaye kwathintela elide phambi kokuba axilonge kwezinye iindlela ezisemgangathweni. Ngenxa yoko, bakufikise umzimba isigulana ngaphantsi yingozi kakhulu.

Kwaye kwimeko iintlobo ezahlukeneyo lymphoma, PET uphando kwi inokuthenjwa nje ayikwazi indawo. Ezinye iindlela zophando apha zingaphantsi kakhulu PET sifo, kokubini ichanekile kwaye iphelele, kwaye izinga Ubhaqo Ukudlulela.
