Chifukwa cha kusintha kwa chidziwitso cha thanzi la anthu komanso kugwiritsa ntchito kwambiri njira yochepetsera chiopsezo cha matenda a mtima (CT) poyesa thupi lonse, timitsempha ta m'mapapo timayamba kupezeka panthawi yoyezetsa thupi. Komabe, kusiyana kwake ndikuti kwa anthu ena, madokotala amalangizabe odwala kuti ayesedwe bwino ndi njira yowonjezerera chiopsezo cha matenda a mtima (CT). Sikuti izi zokha, PET-CT yalowa pang'onopang'ono m'munda wa masomphenya a aliyense m'chipatala. Kodi kusiyana kwake ndi kotani? Kodi mungasankhe bwanji?
Chomwe chimatchedwa CT yowonjezera ndi kubaya mankhwala otsutsana ndi ayodini kuchokera m'mitsempha kupita m'mitsempha yamagazi kenako ndikuchita CT scan. Izi zimatha kuzindikira zilonda zomwe sizingapezeke mu CT scan wamba. Zingathenso kudziwa kuchuluka kwa magazi a zilonda ndikuwonjezera kuchuluka kwa matenda ndi njira zochiritsira.
Ndiye ndi matenda amtundu wanji omwe amafunikira CT yowonjezera? Ndipotu, CT scan yowonjezera ndi yofunika kwambiri pa tinthu tolimba tomwe tili pamwamba pa 10 mm kapena tinthu tating'onoting'ono tomwe tili pamwamba pa hilar kapena mediastinal masses.
Ndiye kodi PET-CT ndi chiyani? Mwachidule, PET-CT ndi kuphatikiza kwa PET ndi CT. CT ndi ukadaulo wa tomography wa pakompyuta. Kufufuza kumeneku tsopano kumadziwika bwino ndi banja lililonse. Munthu akangogona pansi, makinawo amaunika, ndipo amatha kudziwa momwe mtima, chiwindi, ndulu, mapapo ndi impso zimaonekera.
Dzina la sayansi la PET ndi positron emission tomography. Asanachite PET-CT, aliyense ayenera kubaya jekeseni yapadera yotchedwa 18F-FDGA, yomwe dzina lake lonse ndi "chlorodeoxyglucose". Mosiyana ndi shuga wamba, ngakhale kuti imatha kulowa m'maselo kudzera mu zonyamula shuga, imasungidwa m'maselo chifukwa singathe kutenga nawo mbali pazotsatira.
Cholinga cha PET scan ndikuwunika momwe maselo osiyanasiyana amagwiritsira ntchito shuga, chifukwa shuga ndiye gwero lofunika kwambiri la mphamvu ya kagayidwe kachakudya m'thupi la munthu. Shuga ikadyedwa kwambiri, mphamvu ya kagayidwe kachakudya imakula. Chimodzi mwazinthu zofunika kwambiri za zotupa zoyipa ndikuti kuchuluka kwa kagayidwe kachakudya kumakhala kwakukulu kwambiri kuposa kwa minofu yabwinobwino. Mwachidule, zotupa zoyipa "zimadya shuga wambiri" ndipo zimapezeka mosavuta ndi PET-CT. Chifukwa chake, tikulimbikitsidwa kuchita PET-CT ya thupi lonse chifukwa ndi yotsika mtengo kwambiri. Ntchito yayikulu ya PET-CT ndikuzindikira ngati chotupacho chafalikira, ndipo kukhudzidwa kwake kumatha kufika 90% kapena kuposerapo.
Kwa odwala omwe ali ndi ziphuphu m'mapapo, ngati dokotala akuona kuti ziphuphuzo ndi zowopsa kwambiri, akulangizidwa kuti wodwalayo apimidwe ndi PET-CT. Chotupacho chikapezeka kuti chafalikira, chikugwirizana mwachindunji ndi chithandizo cha wodwalayo, kotero kufunika kwa PET-CT sikunganyalanyazidwe. Ndipo ndi fanizo. Ichi ndi chimodzi mwa zifukwa zazikulu za PET-CT. Palinso mtundu wina wa wodwala yemwe amafunikiranso PET-CT: pamene n'kovuta kuweruza ziphuphu zosavulaza komanso zoyipa kapena zilonda zomwe zimakhala m'malo, PET-CT ndi njira yofunika kwambiri yodziwira matenda. Chifukwa zilonda zoopsa "zimadya shuga wambiri."
Mwachidule, PET-CT imatha kudziwa ngati pali chotupa ndipo ngati chotupacho chafalikira m'thupi lonse, pomwe CT yowonjezera nthawi zambiri imagwiritsidwa ntchito pozindikira ndi kuchiza zotupa zazikulu za m'mapapo ndi zotupa za m'mimba. Koma mosasamala kanthu za mtundu wanji wa kafukufuku, cholinga chake ndikuthandiza madokotala kupanga zisankho zabwino kuti apereke mapulani abwino ochizira odwala.

Monga tonse tikudziwira, chitukuko cha makampani opanga zithunzi zachipatala sichingasiyanitsidwe ndi chitukuko cha zida zamankhwala zingapo - majekeseni osiyanitsa ndi zinthu zina zothandizira - zomwe zimagwiritsidwa ntchito kwambiri m'munda uno. Ku China, komwe kumadziwika ndi makampani opanga zinthu, kuli opanga ambiri otchuka kunyumba ndi kunja chifukwa chopanga zida zojambula zithunzi zachipatala, kuphatikizapoLnkMedKuyambira pomwe idakhazikitsidwa, LnkMed yakhala ikuyang'ana kwambiri pa ntchito yopangira majekeseni otsutsana ndi mpweya woipa kwambiri. Gulu la mainjiniya la LnkMed limatsogozedwa ndi PhD yokhala ndi zaka zoposa khumi zokumana nazo ndipo ikuchita kafukufuku ndi chitukuko mozama. Motsogozedwa ndi iye,Injector ya mutu umodzi ya CT,Injector ya mutu wa CT iwiri,Injector ya MRI contrastndiInjector yotsutsana ndi kuthamanga kwa magazi (Angiography)Zapangidwa ndi zinthu izi: thupi lolimba komanso laling'ono, mawonekedwe osavuta komanso anzeru ogwirira ntchito, ntchito zake zonse, chitetezo champhamvu, komanso kapangidwe kolimba. Tikhozanso kupereka ma syringe ndi ma chubu omwe amagwirizana ndi mitundu yotchuka ya ma injector a CT, MRI, DSA Ndi malingaliro awo oona mtima komanso mphamvu zawo zaukadaulo, antchito onse a LnkMed akukupemphani kuti mubwere kudzafufuza misika yambiri pamodzi.
