Nguva uye nei PET Scans Inoshandiswa kuRung Cancer?
Tsanangudzo: PET Scan (Positron Emission Tomography)
PET scan is radiological test used to evaluate and stage stage cancer and is often used with CT scan.
Ko PET Scan yakasiyana Sei nedzimwe miedzo?
Apo CT inotarisa uye MRI inotarisa maitiro emumuviri (mapfupa, nhengo nezvimwe mishonga,) PET inoona kutarisa kuti muviri unoshanda sei (sei izvo nhengo idzi uye matukisi ari kushanda.) Kunyange zvazvo CT uye MRI inoonekwa semagadzirirwo emagariro ekufungidzira, PET inofungidzirwa maitiro ekufungidzira.
Zvikonzero zvePET Scan
Pane zvikonzero zvakawanda nei chiremba wako angakurudzira PET scan. Zvimwe zvezvi zvinosanganisira:
- Kuongorora chirwere.
- Kuona kana chirwere chepapu chisingawaniki chinoratidzika kuva chekenza kana kuti chinowanzoonekwa sechivara chechivara kana chisina kenza. Mune zvimwe zviitiko, PET scan inogona kusiyanisa musiyano pakati pechirwere chinopisa uye chinopisa pasina chidimbu chemapapu.
- Kupedzisa chirwere chekenza nekusarudza kuti kurega kenza yakapararira sei. PET scan ndiyo yakaoma kupfuura CT pakuona mastasisita muchechi asiri duku chemapapu emapapu uye inobatsira pakusiyanisa pakati pepakati pekidiki uye duku . Kuongorora kwepET kunobatsirawo pakuongorora lymph nodes iyo yakanaka kune kenza. Somuenzaniso, PET scan dzimwe nguva inogona kuongorora lymph nodes mu mediastinum pasina chido chekuita mediastinoscopy (nzira yekuvhiya inoshandiswa kuongorora nzvimbo ino.)
- Kugadzirira zvirongwa zvakanakisisa zvekurapa kwemumwe mukenza wemapapu.
- Kuona kuti kurapa kuri kushanda sei.
- Kutarisa kwekudzoka kwemukenza wemapapu . Semuenzaniso, zvinogona kunge zvakaoma paC CT kuti uone kana nzvimbo iri mumapapu inenge iine mavara mashoma zvichibva pakurapa kwemaawa kana kuti panzvimbo iyo, kudzokorora kwechirwere.
- Kubatsira kutsanangura kufungidzira. Mishonga ine zvishoma zvishoma zvekuvhara glucose zvingave zvisinganyanyi kurwisa uye kuva nehuwandu hwakanaka kune avo vane huwandu hwakawanda.
Nemukenza wemapapu, chirwere chePET chinowanzoitwa nevarwere vane kenza yemapapu yekutanga iyo chirwere chinogona kuitwa nechinangwa chokurapa chirwere chacho. Kune vanhu vane kenza yemukenza yakapararira kupfuura imwe yero, chirwere hachisi chakanakisisa. Mune rumwe ruzivo rwakaratidzwa kuti mune 1 muvanhu vashanu vaiva nekenza yakaonekwa seyakagadziriswa, PET scan yakakwanisa kuongorora kupararira kwekenza yakanga isingazivikanwe kuitira kuti chirwere chisina kufanira chakanga chisina kuitika.
PET Scan Process
Ne PET scan, kamudiki kanonzi sugaractive shuga (fluorodeoxyglucose kana FDG) inopindwa muropa. Kukura masero anoshandisa shuga. Kukurumidza kukura masero akadai sekenza masero anotora shuga uye inogona kuonekwa pane 3-dimensional imaging.
Pamberi pekuongorora kwePET, vanhu vanowanzorayirirwa kuti vasadya kana kunwa (kunyanya kudya kudya kwemashuga) kwechinguva uye kuderedza maitiro kwemaawa makumi maviri nemaviri. Inonzi radioactive sugar (fluorodeoxyglucose kana FDG) inoshandiswa, uye murwere anorindira kweawa kuti muviri uwane shuga. Zvadaro shanduro inoitwa inotora maminitsi 30 kusvika ku60.
Zvinogona kuva zvinotyisa kufunga pamusoro pezvinhu zvakasvibiswa zvinoshandiswa mukati momuviri wako, asi chaizvoizvo, kungoita zvishoma zvishoma kwehuwandu hwemhepo huripo hunoitika.
Iyi mihara inopera nokukurumidza mushure mejojo, asi vamwe veo oncologist vanokurudzira kuti vanhu varambe vari kure nevadzimai vane pamuviri uye vana vaduku pazuva rekuedzwa kunoitwa.
Kukanganisa kwePET Scans - Nhema Nemaonero uye Nhema
Sezvakaita mimwe miedzo yakaitwa nekenza, zvinogona kuva zvose zvisiri zvenhema uye zvipo zvenhema paPET scan. Kuipa kwenhema kunowanikwa apo pane kusakanganisika kuripo, asi hazviwanikwe paPET scan. Chinhu chine nhema chinowanikwa apo PET scan inoratidza kuti chimwe chinhu chirwere, asi muchokwadi, hazvisi chinhu chinokosha, chakadai sechivara chechivara. Mamiriro akafanana anokonzera pfungwa dzenhema muPET anoongorora kanzera yemapapu dzinosanganisira post-obstructive pneumonia (a pneumonia inowanikwa mumapapu eropa kune uko gumbo rinodzivirira mhepo) uye silicosis.
Mafungiro enhema anowanzoonekwa munzvimbo dzine kuporesa kuri kuitika, zvakadai senzvimbo iyo chirwere chakaitwa.
Nenzira yakawanda, PET kuongorora kwekenza yemapapu ine unhu hwepamusoro uye yakaderera. Kunzwisisika kwakanyanya kunoreva kuti kuedza kwakanaka kwazvo pakusarudza zvisinganzwisisiki, uye kunogona kusiyanisa nzvimbo dzakashata uye dzakaipa zviduku se 1 cm muhupamhi. Izvo zvakaderera zvinoreva kuti kuwana hakurevi kureva chirwere uye izvo zvinotarisa zvakadai sehutachiona kana kuvhiringidzika kunogona kukonzera kusagadziriswa kwepfungwa.
Mienzaniso: Kunyange zvazvo Jill's CT scan yakakundikana kuziva chirwere chemapapu mune mamwe masukisi kunze kwemapapu ake, pET yake scan yakaratidza kuti chirwere chepapu rake chakanga chapararira uye kuti kurapwa kwaisazova kwakanakisisa kurapa kwake.
