PET / CT - wotani kafukufuku?

Kale ambiri a inu mukudziwa, akulankhula za PET / CT, umene ndi watsopano, yolondola kwambiri njira matenda oyambirira a khansa, matenda a ubongo ndi pathologies mtima. Iye, mosiyana CT kapena Kujambula sangosonyeza chithunzi cha makhalidwe anatomical wodwalayo, ndipo analanda ndondomeko ya ntchito kwa ziwalo zina ndi zimakhala. Kodi chimodzimodzi wochititsidwa PET mapanga sikani ndi mmene muyenera kukonzekera izo, ife kuphimba m'nkhani ino.

Kodi matenda amapezeka ntchito PET / CT?

Positron umuna tomography ndi phunziro zovuta umene mwina Kupeza Vuto zotupa amene sabala mawonetseredwe matenda ndi khansa metastasis mu siteji koyamba. Komanso, limakupatsani kulamulira matenda, zotsatira ndi mphamvu ya mankhwala.

Mu cardiology, PET / CT diagnostics ntchito milandu ya matenda a mitima ndi isanafike inatsekeratu mtsempha wamagazi kulambalala kumezetsanitsa. Mu ubongo ndi izo amapezeka ofoola ziwalo ndi mu maganizo - matenda a Alzheimer pa siteji oyambirira, pamene mawonetseredwe kunja inayamba matenda silinakwaniritsidwe anati. Mwa njira, ndi kafukufuku limathandiza kusiyanitsa matenda a Alzheimer ku pathologies ena chifukwa mu senile maganizo (matenda Parkinson kapena Huntington a).

Mothandizidwa ndi PET imawunikidwa ubongo kugwira ntchito pambuyo sitiroko ndi khunyu amapezeka ndi khunyu.

PET / CT: Reviews za ubwino njira ya matenda

Pamaso zina zamakono njira diagnostics zambiri ubwino wa PET. Choyamba, njira imeneyi - molondola kwambiri kwa anthu onse alipo, ndi Komanso akhoza m'malo Kafukufuku angapo chikhalidwe. Komanso, PET chimayambitsa kupweteka alibe mavuto mbali pa thupi ndi angazindikire ndondomeko matenda pa siteji oyambirira.

Kupezeka madokotala za ndemanga PET / CT kulola ife kuti kulankhula za njira imeneyi monga njira kupeza mfundo zodalirika gawo limene zooneka diso structural kusintha limba alibe kulibe. Ndipo izi, ngati inu mukudziwa, limachititsa kuyamba chithandizo pa magawo oyambirira a matenda, imene kwambiri kumawonjezera mphamvu ya mankhwala.

Mfundo mayeso PET

Dziwani, akulankhula za PET / CT zimaonetsa kuti kafukufuku limakupatsani kulemba magazi ziwalo ndipo zimakhala, komanso mowa wa shuga lomaliza.

Mu thupi la nkhaniyi chikuyendetsedwera yaing'ono, vuto lililonse kwa anthu, kuchuluka kwa mankhwala nyukiliya yomwe ikuchitika ndi magazi zimakhala. cheza osauka kubwera kwa izo, PET chili ndi imafalikira kuti kompyuta. Apo pakubwera processing mauthenga ndi chilengedwe cha fano. Ndi zambiri za mankhwala nyukiliya zili minofu, m'pamenenso iwo kuyang'ana pa chithunzi - otchedwa "otentha" malo, ndi malo thunthu ndi ang'ono, kuyang'ana kuzimiririka - ndi "ozizira" malo.

Akutukuka maselo a khansa pacimake kufunika shuga m'menemo umayenda kagayidwe yogwira kuti amakhala ndi zithunzi pambuyo PET / CT yowala ( "otentha") fano. Choncho, matenda PET angathe kuonedwa kokha kuyamba kukula nthenda ya maselo a khansa, ndipo ngakhale kusintha kukula Mapa.

Njira PET / CT

Malinga ndi zimene anayendera ntchito, adokotala akhoza kusowa kapena njira zina matenda anafotokoza ndi radiopharmaceuticals osiyana:

• Pet ndi 11C-choline;
• PET ndi 18F-fluorodeoxyglucose;
• Pet ndi 11C-methionine;
• Pet ndi 13N-ammonia.

Mwachitsanzo, kwa matenda a zilonda glioma (ubongo zotupa) anafuna kwa PET / CT ndi methionine, moti kupenda mlingo wa chotupa chija.

Kudzapeza zinali odalirika, dzana kuphunzira wodwala ndi bwino kuti achotse ku chakudya zakudya zonse mapuloteni munali: nyama, nsomba, mkaka ndi soya. Mukhoza kudya zamasamba ndi zipatso. Mu chipatala kuti abwere kusala kudya, ndi kuloledwa kumwa madzi zedi malire (koma osati fizzy kapena lokoma).

Nthawi zina, matenda ikuchitika ndi choline

Chaka chikhalidwe thupi kansa ya prostate komanso zotupa a chiwindi ndi ubongo zambiri anagwira PET / CT ndi choline.

mankhwala kumatanthauza yomanga maselo makoma, kotero oyamba a radionuclide mu timatha kuona m'maganizo mwanu pamaso pa metastases ngakhale ang'ono amene kuonekera zithunzi mu mtundu mfundo wowala.

Maphunziro awa kunachitika mu magawo 2 - nthawi yomweyo pambuyo ka radiopharmaceutical ndi pambuyo mphindi 40. Chindodo zachitika pa chopanda kanthu m'mimba ndi popanda madzi (m'mawa izo kwathunthu lilibe).

masabata 1-2 pamaso kumupima wodwala tikulimbikitsidwa amachotsedwa zakudya za:

• mazira;
• nandolo;
• soya, khobwe, nyemba;
• chiwindi (ndi zina);
• sipinachi;
• kabichi;
• mtedza;
• Mapila;
• lalanje madzi ndi mavitamini iliyonse (makamaka B gulu).

Monga kafukufukuyu wochititsidwa

Mu zipinda kumene PET / CT bwinobwino mtima linafunsidwa kwa zimitsani a m'manja ndi kupereka kupita ku chipinda wodikira kumene mtima mkati mphindi 20 ayenera kupuma kukhadzikika. M'pofunika kuwongolera zithunzi.

Kenako examinee jekeseni radiopharmaceutical ndi kudikira theka lina ola limodzi, mpaka nkhaniyi ndi anagawira mu zimakhala thupi. Mwa njira, ngati pa nthawi ino pali kufunika kupita ku chimbudzi, simungathe zawozo. Komanso, odwala akulimbikitsidwa kupita sikana PET izo zikuwoneka ngati makina X-ray. kumatenga mphindi 45 kafukufuku ndondomeko yokha (ubongo chindodo Komabe, maora ndi 1.5).

Ngati kofunikira pa ndondomeko kwa wodwala kufikako wina ku ndodo zachipatala. Pankhani ya phunziro mtima mtima angapereke maphunziro olimbitsa thupi omwe lizidzachita mbali ya magazi ndi kugwira ntchito kwa thupi ili.

Zochizira chuma ayenera maola angapo kwa masiku 2. Izi zidalira pa mtundu ndi kuvuta kafukufukuyu.

Kodi lonse thupi Kupenda

PET / CT ndondomeko thupi lonse kawiri kawiri zimachitika pansi mafupa a chiuno ndi. Funso kapena nthawi yomweyo kuwagwira Chigaza, akhala maganizo. Iwo samati mu malls ambiri. Ngati Kafukufuku zofunika anatomically m'malo ovuta anachitika aiming kuyang'ana Mosiyana wothandizila (ayodini Kukonzekera).

Kuyang'ana pa chiyambi, kawirikawiri ndi malo m'chiuno, kupewa kusintha fano limene limapezeka chifukwa cha kudzazidwa mwapang'onopang'ono chikhodzodzo. Wachina chilichonse ndi scanned mphindi zosachepera 4 (umuna Jambulani) kuphatikiza wina 2 Mphindi (HIV Jambulani).

PET jambulani thupi lonse amalola kuti wathunthu dongosolo ntchito ngati n'kotheka, kuchotsa zonse minofu akhudzidwa.

Contraindications kwa PET / CT

Tikumbukenso, kunena za PET / CT, amene ayesedwa mu zina ndalama ndi contraindicated, kuyambira deta zinthu molakwika. Mwachitsanzo, izi zikuchitika mu oyambirira postoperative nthawi pambuyo biopsy lotseguka (mu milandu kuyembekezera osachepera masabata 4 pambuyo opaleshoni). PET amadziwikanso contraindicated pambuyo mankhwala amphamvu posachedwapa kapena mankhwala cheza. Zikatero, analimbikitsa miyezi itatu yopuma.

njira yotupa mu thupi: abscesses, matenda sarkidoz - awapatse zotsatira zabodza HIV pamene kuyang'ana. Zikatero, muyenera kukhala osamala zomwe zikusonyeza PET / CT.

Nthawi zina ena (monga claustrophobia kapena ngati wodwalayo ali ndi vuto la supine udindo) protocol chindodo imasiyana malingana alili.

Kodi Ndiyenera kukumbukira pokonzekera PET / CT

Kuti PET / CT diagnostics sudzapereka inu kusamva, ndipo zotsatira zake zinali khalidwe zabwino, muyenera kutsatira ochepa malamulo ambiri pa mtundu wa ndondomeko:

• Kuchititsa PET / CT ayenera kuvala mwachikondi ndi wabwino.
• Zovala ndi thupi ayenera mulibe zitsulo ndi zodzikongoletsera.
• Popeza mukhoza kutenga 1 lita imodzi ya mowa ndi unsweetened madzi enaake.
• Akazi ayenera kuika mu dokotala kudziwika mimba wogwila kapena zotheka, komanso kuyamwitsa, chifukwa chindodo ndi monenetsa zomangidwa zimenezi.
• Onetsetsani kuti mwatchula pamaso pa thupi lawo siligwirizana.
• Kwa odwala ndi shuga, amafuna kukonzekera mwapadera kwa PET / CT.
• Mu zochitika komwe kafukufukuyu amachitika mafupa a chiuno ayenera kugwiritsira mu mkodzo m'chikhodzodzo catheter.
• Kwa kumupima wodwala ayenera mapulani simungathe kusintha udindo.
• Ngati malangizo ena siyikuperekedwa, nthawi yomweyo pambuyo chindodo kafukufuku akanatha kubwerera kwa moyo wabwinobwino, ndi imathandizira pa Kupha radiopharmaceuticals, m'pofunika kumwa madzi ambiri ngati kuli kotheka.

Kuphindula zotsatira za PET / CT: mapeto Izi zingatanthauze?

Pambuyo kuyang'ana ikuchitika mwa dzanja la wodwala apatsidwa. Pomwepo kofunika kuti achenjeze aliyense amene amagwira ntchito kafukufuku ameneyu, kuyesa kudzimvera kuwachitira - Ndi udindo wa yekha dokotala kupezeka (ogwira ntchito kuchipatala, kuchititsa PET, salola amavomereza aliyense).

Kupanda ukatswiri kungachititse kuti molakwa za zotsatira. Iwo Kungakhale kovuta kuposa kwenikweni, kapena, Tikawonetsetsa, musati amafuna alowererepo zachipatala. PET / CT zotsatira angathe kutanthauziridwa molondola yekha ndi dokotala, amene wakutuma iwe kuti kafukufuku ameneyu. Ndipo ngati wasankha yekha, ndiye, ziribe kanthu chimene chidzagwa mapeto kuchokera maganizo anu, ndi bwino kusonyeza mbiri katswiri wake kwa matenda zolondola ndi chithandizo choyenera ntchito.
