PET scan, inonziwo positron emission computed tomography, bvunzo yekufungidzira inoshandiswa zvakanyanya kuongorora kenza kare, kutarisa kukura kwethumba uye kana paine metastasis. PET scan inokwanisa kuratidza mashandiro anoita mutumbi, kuburikidza nekushandisa chinhu chine radioactive, chinonzi tracer, icho, kana chakayamirwa nemuviri, chinoburitsa mwaranzi inotorwa nemidziyo uye yochinjwa kuita mufananidzo.

Iyo bvunzo haikonzeri kurwadziwa, zvisinei inogona kukonzeresa kusagadzikana kana munhu wacho ari claustrophobic, sezvazvinoitwa mune yakavharwa michina. Kunze kwekushandiswa zvakanyanya mu oncology, PET scan inobatsirawo mukuongororwa kwezvirwere zvetsinga, senge Alzheimer's uye pfari.

PET scan bvunzo inowanikwa muzvirongwa zvehutano uye SUS iyo inongoitirwa kuongororwa, kuongororwa uye kuongororwa kwecancer yemapapu, lymphomas, cancer cancer, rectal cancer uye immunoproliferative hosha, senge yakawanda myeloma, iri chirwere umo masero eropa anotanga. kuwedzera uye kuunganidza mumongo wemapfupa. Tsvaga kuti ndezvipi zviratidzo uye maitiro ekuziva akawanda myeloma.

Chii ichochi

PET scan ndeyeyedzo yekuongorora iyo yakasiyana nedzimwe bvunzo dzekufungidzira, senge computed tomography uye magnetic resonance imaging, semuenzaniso. Izvi zvinodaro nekuti zvinobvumidza kuona matambudziko padanho remaseru kuburikidza nekubuda kwemwaranzi, ndiko kuti, inokwanisa kutarisa mashandiro emagetsi emasero, ichiratidza cancer kare, semuenzaniso.

Pamusoro pekushandisa kwayo mukuzivikanwa kwekenza, PET scan inogona kushandiswa ku:

• Tsvaga matambudziko emitsipa, senge pfari uye dementias;
• Tarisa matambudziko emwoyo;
• Chengetedza kushanduka kwekenza;
• Chengetedza kupindura kurapi;
• Ziva metastatic maitiro.

PET scan zvakare inokwanisa kuona kuongororwa uye kutsanangura kufungidzira, ndiko kuti, mikana yekuvandudza kana kuwedzera kuipa kwemurwere.

Chiyero chinoitwa nekutaurisa kwemuromo, kuburikidza nezvinwiwa, kana akananga mukati mutsinga yetracer, iyo inowanzove glucose yakaratidzirwa neine radioactive chinhu. Nekuda kwekuti tracer iri glucose, bvunzo iyi haipe njodzi pahutano, sezvo iri nyore kubviswa nemuviri. Iyo yekuteedzera inofanirwa kupihwa yekutsanya kwemaawa mana kusvika matanhatu, zvinoenderana nemazano ekurapa, uye PET scan inoitwa mushure meawa rimwe chete, kubvumira nguva yekuti chinhu chine radioactive chinyurwe nemuviri, uye chinogara kweinenge awa.

PET scan inoita kuverenga kwemuviri, kutora iyo yakaburitsa mwaranzi uye kugadzira mifananidzo. Mukuferefetwa kwemabhuru maitiro, semuenzaniso, kudyiwa kweshuga nemaseru kwakakura kwazvo, nekuti glucose ndiyo sosi yesimba rinodikanwa kupatsanura masero. Nekudaro, iwo mufananidzo wakaumbwa unenge uine nzvimbo dzakakora apo paine kudyiwa kukuru kweshuga uye, nekudaro, kubuda kukuru kwemwaranzi, iyo inogona kuratidza bundu.

Mushure mekuongorora zvakakosha kuti munhu anwe mvura yakawanda kuitira kuti tracer ibviswe zviri nyore. Uye zvakare, zvinogona kuve kuti pane zvinyoro nyoro zviratidzo, senge kutsvuka, uko kwakateedzera tracer.

Muedzo hauna zvinopesana uye unogona kuitwa kunyangwe kune vanhu vane chirwere cheshuga kana matambudziko eitsvo. Nekudaro, vakadzi vane nhumbu kana vanoyamwisa havana kurairwa kuti vaite iyi bvunzo yekuongorora, sechinhu chine mwaranzi chinogona kukanganisa mwana chinoshandiswa.
