Radionuclide teknolojia ikozvino inoshandiswa zvakashandiswa mumishonga yenyukireya uye mazuva ano kuongororwa maitiro. Imwe yenzira dzakanakisisa dzekudzidzisa tsvina yemhepo ndeipi positron emission tomography. Kubudirira kwekuongororwa kwakadai ndiko kukwanisa kuvaka katatu-dimensional model of biological processes uye nhengo dzomukati.
Chii chinokonzera-positron tomography?
Icho chinonyanya kukosha ichocho chiri muzvinhu zve positrons (particles ane chekuita zvakanaka). Vane maitiro akasiyana-siyana ekugadzirisa simba muhutano ne-high-energy rayation.
Pamberi pe positron emission tomography kana PET, chinhu chinokonzerwa nemasasa chinoshandiswa mukati-kati, zvinowanzova fluorine-18, asi dzimwe nguva carbon-11, oksijeni-15 uye nitrogen-13 inoshandiswa. Kwenguva yakati munhu anoda kugara mune imwe nzvimbo yezororo, kuitira kuti positron-emitting isotopes inoparidzwa mumuviri. Mushure meizvi, murwere anogadzirirwa mune chimwe chinhu chakakosha, chakafanana neMRI, umo muviri wake unotarisana nemirairo yakaipa zvachose. Kana paine kushungurudzika mune zvigadzirwa zvemagetsi kana kune dzimwe nyika dzisingawaniki, nzvimbo dzinotambudza dzinowedzera huwandu hwemashoko, izvo zvakanyorwa nemakombiyuta emichina. Zviratidzo zvinotaridzika zvinoputika, uye utachiona hwakasiyana kubva kune nhengo dzakanaka muvara.
Where is positron emission tomography used?
Chaizvoizvo, inotsanangurwa teknolojia inoshandiswa pakuongororwa kwekenza. PET inogona kuona kenza pamatambo makuru kana zero, apo pachinenge pasisina zviratidzo. Zvechokwadi, tomography inoshandiswa kuongorora tumarara:
- cervical;
- chiedza ;
- prostate gland;
- mudumbu.
Iyo nzira inopa kuongororwa kweeoplasms muchiyero kubva pa 1 mm, uyewo kuongororwa kwezvirongwa zvemasastasis. Zvakakosha kuziva kuti tomography inobatsira kuona kuti ingabudirira sei chemotherapy. Nzira yacho yakaitwa mushure mokurapa kwemishonga inoratidza kuderera kwebasa rekenza masero, kukura kwavo nekufambira mberi.
Mukuwedzera, PET inoshandiswa mumoyo wepoddiology yekurekora chirwere chemoyo chinonzi coronary, kushungurudzika kwemhepo, kupera kwemakironi emakoroni, zvinokonzerwa nehutano hwemwoyo nekudzivirira, stenosis. Iyo inyanzvi inowedzera kutaridzika kwemuviri wepfungwa mumatatu ekuongororwa mumakumi makumi matanhatu.
Uyewo positron emission kombiyuta tomography yeuropi inoshanda zvakashandiswa. Kuongororwa nenzira yePET inobvumira kuona:
- focal neoplasms;
- kenza;
- dementia;
- kuora mwoyo;
- Chirwere cheAlzheimer;
- kuora mwoyo kunetseka;
- vascular pathologies;
- migumisiro yekurohwa , ischemic attack.
Sezvo chirwere chinoratidzira, kana iwe ukaita positron kubudisa tomography munguva, iwe unogona kukura yakakodzera uye yakakodzera kurapwa regimen, iyo inowanzosiyana zvakasiyana
Kunyanya kukosha kushandiswa kwePET muurorology. Chirwere cheAlzheimer mukutanga kwayo chinogona kugadziriswa kuchipatara, uye chirwere chinorwara chinorwara chichabatsira zvikuru kupedza kupararira kwehutachiona. Kutanga kwokutanga kwehutano kunopa kuderedzwa kwehuwandu hwekufa kwehupi hwehupi uye kuguma kwekushanda kweimwe nzvimbo dzayo.
