Ichangobva kenza chirwere nzira. Positron achine tomography. PET Ongororo

Positron anobuda computed tomography, kana PET CT - kudzidza dzevanhu zvomukati nokuda radioisotope kuongorora chirwere. PET Ongororo anonziwo maviri-photon anobuda tomography, nokuti kuti nzira iyi inobva kuziva miedzo wegamma-ray peya.

PET chinhu yepamusoro nzira kuti mangwanani chirwere kenza, cardiac uye chetsinga zvirwere. In oncology PET rinoshandiswa kuti chirwere ose akaipa namamota, metastasis kure kutsvaka uye kuongorora kurapwa.

Positron achine tomography kunoratidzwa yakakwirira rakarurama tsvakurudzo, pasipasi nemwaranzi kuona mutumbi, mukana kuongorora zvose nhengo ari chete kushanya. Kudzidza pacharo ndiro chose nyarara.

PET, kufanana nezvimwe tsvakurudzo nzira, kudzidza haana anatomical nhengo uye munyama, uye makemikari pezvakaitwa zvichiitika kwavari. Kana oncology kwemakemikari pezvakaitwa vanochinjwa, izvi zvinogona kuonekwa sechinhu nokuchinja ruvara uye kusimba acho, zvakasiyana vasingambooni chakaipa nazvo.

Saka, nekuti PET ona Cancer muitiro unogona akatanga refu asati aumba bundu. Ultrassom, CT, MRI anogona kuzviona dambudziko chete kana bundu yakatotanga azviratidza uye ukasvika imwe saizi (nokuti ano MRI midziyo haidereri pane 1-2 millimeters).

PET ruchatibatsira kuona akaipa kana benign bundu, riri kunyanya kukosha kana pasina mukana kuwana biopsy zvinhu.

PET anoona ropa kuyerera kuti munyama uye zvinyama kudyiwa shuga uye okisijeni. muviri murwere akaiswa imwe mari radioactive zvinodhaka (radioactive shuga). The nemwaranzi kubva radioactive shuga chakanyorwa scanner chaiyo iyo transmits mashoko ose ari kombiyuta. The pezvakaitwa kombiyuta uye visualizes nayo.

Masero vane rakawedzera muviri upise zvakawanda shuga. Hazvina ichi chakasiyana kenza kubva dzose. The zvakawanda radioactive bhuku unobatwa zvinyama, havazombonyanyi kucherekedza zvichiguma mufananidzo. zvikamu yakadaro inonzi "kupisa". Asiwo, duku rakanga rakundwa chigadzirwa - mufananidzo nokuda kwenhamo inotengwa kwokurangana vakadaro vanonzi "inotonhora".

Muviri mu nyanyisa mapundu zviri kupfuura mune utano munyama. Naizvozvo, nyanyisa mapundu kugadzirazve yakajeka, "kupisa" mufananidzo.

Pacharo radioactive shuga decays isingasviki zuva uye panobviswa chose pachitunha.

Nokuda kuti PET kudzidza anofukidza muviri wose wose, zvingaite yakakwana operative urongwa. Izvi Ichabvisa zvose hosha zvinyama, kana zvichibvira mune chimwe nechimwe. Izvo ndichazoendawo kuderedza mukana kwohumwe wava kusvutazve.

Uchishandisa PET anogona zvakarurama zvakagadzirira kenza, ona, kana akatema node nodes vasati vakatanga kuwedzera. Izvi zvinoita kuti tikwanise kushandisa Anti-kenza kurapa zvikuru zvinobudirira.

Panoperera mishonga uye mwaranzi kurapa PET kuona kubudirira kurapwa.

PET Ongororo zvicharatidza metastases apo dzimwe chirwere nzira hausati kuita kudaro.

Somuenzaniso, kudzidza chiedza achibatsirwa X-ray iri nyaya shading chikonzero chete nokufungirana kuvapo metastases. Zadzisai kuvapo kwavo chinogona dzechimwe ponji rinenge kana PET, asi PET Ongororo achasarudza kukura metastasis uye anoziva kupararira masero kenza pakutanga nzendo chirwere.

Kusiyana scintigraphy, uyewo nokushandisa radioisotopes mufananidzo apo-dimensional matatu PET yokudzidza kuti inogonesa kupima yakarurama mufananidzo chirwere.

Kudzidza pacharo pamusoro wavanoti: murwere orara pamubhedha, izvo kusingachakosheswi muchina. The chikwata pacharo sokunge pfupi chubhu. The nzira rinovapo pakati hafu yeawa. Tisati kuti, murwere anogamuchira inhalation kana nomutsinga zvikuru akagadzira radioactive zvinodhaka.

Contraindications nokuti positron achine tomography wedzeredzei. PET tarisei contraindicated vakadzi vane pamuviri uye lactating, uyewo avo varwere vasingakwanisi kudzikamisa, pasina kufamba, gara pamubhedha nguva inodiwa yokutsvakurudza.

Positron achine tomography - kuongorora inodhura kwazvo. Tinorasikirwa 50 000 rubles. MuRussia, kuti midziyo yokudzidza zvakadai ndizvo chete mumaguta makuru.

Chokwadi, hazvina musoro kuti kuitisa PET atarise kuzvidzivirira bvunzo hwakanaka munhu. Zviri zvakakwana kuti nguva kuongorora kuti bundu zvezvinangwa.

Kana pachisikirwo anonoke bundu metastasizes, uyewo muchiitiko ichi tinogona ndigoisa isu oncomarkers kana zvimwe miedzo uye kugara kuongororwa dzokurapa pane oncologist.

Kana bundu chabviswa mu akazotevera matanho uye kunoita kuti metastasize mhanyisa, zvino musoro kuitisa PET kudzidza. Nepo raiita serine Mari kudzidza murwere anogamuchira somugumisiro pamufananidzo yose kuitika mumuviri wake kuchinja. Kubva musi uyu, chiremba anogona kusarudza nzira yokurapa zvakawanda munyoro uye zvishoma saka zvinodhura.

mishonga PET atarise pane mamiriro mitengo, kakawanda kacho, inofa kuti pacharo uye anoponesa mari zvinodhaka zvakawanda kupfuura mutengo kudzidza pachayo. Uyezve, bundu pezvakaitwa nokuda PET kudzidza kuonekwa uye kudziviswa vasati inogona chirwere nedzimwe tichienzanisa nzira. Somugumisiro, havana kuti mutumbi murwere ndoda inokuvadza.

Zvino nyaya dzakasiyana siyana rwekenza yelymphoma, PET kudzidza pamusoro rakavimbika havambofi kutsiviwa. Other tsvakurudzo nzira pano vari yekudyidzana muduku kuna PET chirwere, zvose zvakarurama uye kukwana, uye metastasis vasabatwa unodiwa.
