Atsopano khansa matenda njira. Positron umuna tomography. PET jambulani

Positron umuna yopangidwa tomography, kapena PET CT - kuphunzira ziwalo anthu ndi matenda radioisotope. PET jambulani amatchedwanso ziwiri fotoni umuna tomography, chifukwa chakuti njira zachokera kudziwika awiri Popanga madzi a gamma-ray.

PET ndi njira zotsogola kwa matenda oyambirira a khansa, mtima ndi matenda a ubongo. Mu Oncology PET ntchito matenda a zotupa zilonda, metastasis kufufuza kutali ndi kuwunika mankhwala.

tomography Positron umuna amakhala ndi lolondola mkulu wa kafukufuku, cheza osachepera kukhudzana ndi thupi, mwai kulingalira za ziwalo zonse mu ulendo umodzi. Maphunzirowa pa okha ndi sabweretsa chisoni kotheratu.

PET, mosiyana ndi njira ina kafukufuku, amaphunzira osati ziwalo anatomical ndipo zimakhala ndi mankhwala zako kunachitika iwo. Pamene Oncology mankhwala zako tisandulika, izi zikhoza kuoneka ngati kusintha mtundu ndi mphamvu ya ndondomekoyi, osiyana mwakale.

Choncho, chifukwa PET onani ndondomeko Cancer akhoza anayamba kale chotupa anapanga. Ultrasound, CT, Kujambula angazindikire vuto kokha pamene chotupa kale anawonekera anafika kukula ena (kwa Kujambula zida zamakono si zosakwana 1-2 millimeters).

PET kumathandizanso kudziwa zilonda kapena chosaopsa chotupacho, umene uli wofunika makamaka pamene palibe kuthekera kupeza biopsy zakuthupi.

PET detects magazi kuti zimakhala ndi mowa minofu ya shuga ndi oxygen. thupi wodwalayo ali anaikapo wina kuchuluka kwa mankhwala nyukiliya (nyukiliya shuga). The poizoni amene shuga nyukiliya analemba sikana wapadera umene transmits mfundo zonse kompyuta. Njira kompyuta ndi visualizes izo.

Maselo ndi bwino kagayidwe zimawononga shuga zambiri. Ndi mosiyana maselo a khansa ku yachibadwa. The magwero nyukiliya akumugwira minofu, m'pamenenso iwo kuyang'ana pa chithunzi chifukwa. Ndime amatchedwa "chamoto". Tikawonetsetsa ang'onoang'ono mankhwala analanda - fano dimmer analandira ziwembu amenewa amatchedwa "ozizira".

Kagayidwe mu zotupa zilonda ndi apamwamba kwambiri kuposa zimakhala wathanzi. Choncho, zotupa zilonda kubala zioneke bwino, "otentha" chithunzi.

Lokha nyukiliya shuga limawola n'kusanduka pasanathe tsiku ndipo kwathunthu inathetsedwa ndi thupi.

Chifukwa chakuti kuphunzira PET chimakwirira thupi lonse wonse, akhoza kupanga mabuku ambiri dongosolo ntchito. Izi adzachotsa zonse za minofu matenda, ngati nkotheka lililonse. Womwe adzakhala kwambiri kuchepetsa kufala kwa chofookacho zina.

Kugwiritsa PET molondola anakhazikitsa maziko a khansa, onani, ngati anakantha lymph mfundo pamaso iwo anayamba kuculuka. Izi zimathandiza kuti ntchito odana ndi khansa mankhwala kwambiri bwino.

Kumapeto kwa mankhwala amphamvu ndi mankhwala cheza PET kudziwa mphamvu ya mankhwala.

PET jambulani ati awulule metastases pamene njira zina matenda simunayambe kutero.

Mwachitsanzo, kuphunzira kuwala mothandizidwa ndi X-ray ndi zinachitikira shading chifukwa chabe kukayikitsa pamaso pa metastases. Tsimikizani pamaso pawo zikhonza puncture minofu zoopsa kapena PET, koma jambulani PET adzaona kukula kwa metastasis ndipo ankadziwa kufala kwa maselo a khansa mu magawo oyambirira a matenda.

Mosiyana scintigraphy, komanso ntchito radioisotopes chithunzi pamene PET kuphunzira atatu azithunzi omwe tikunena kuti chimathandiza ziyenera molondola chithunzi cha matenda.

Maphunzirowa pa okha ndi za ankawona kuti: wodwala akagona pabedi, amene anakankhira mu makina. Unit yokha amaoneka ngati yochepa chubu. ndondomeko kumatenga pakati pa theka la ola. Zisanachitike, wodwala amalandira inhalation kapena m'nsinga mwapadera anakonza mankhwala nyukiliya.

Contraindications kwa positron umuna tomography pang'ono. PET Jambulani contraindicated mu akazi apakati ndi lactating, komanso odwala amene akulephera kuti ndikhadzikike, popanda gulu lililonse, khalani mu bedi nthawi chofunika kafukufuku.

Positron umuna tomography - kufufuza ndi odula kwambiri. Ndipafupifupi 50 000 rubles. Mu Russia, ndi zida zoterozo kuphunzira kokha m'mizinda ikuluikulu.

Ndithudi, izo zimapangitsa neza kuchita PET aone ngati mayeso njira munthu wathanzi. Ndi zokwanira kuti pafunika kumasanthula kwa zolembera chotupa.

Ngati muli ndi chikhalidwe pang'onopang'ono metastasizes chotupa Inunso tikhoza akunjate tokha oncomarkers kapena mayesero ena ndi zonse zachipatala Kupenda pa oncologist.

Ngati chotupa chachotsedwa mu magawo pambuyo amamuchititsa metastasize mofulumira, ndiye n'zomveka kuti phunziro la PET. Ngakhale mtengo mwakuwoneka mkulu wa phunziro wodwala alandira chifukwa cha chithunzi chonse akusinthira kusintha thupi lake. Kuchokera pa ichi, adokotala akhoza kusankha njira modekha ndipo motero zotsikirako mtengo wa mankhwala.

kwa mankhwala PET aone pa mitengo panopa, nthawi zambiri, kulipira kokha ndi kumupulumutsa mtengo wa mankhwala ndi wamkulu kuposa kuphunzira mtengo yokha. Komanso, chotupa njira kuphunzira PET adzakhala wapezeka ndi kuteteza kale iwo akhoza anapezeka ndi njira zina muyezo. Motero, chifukwa thupi la wodwalayo kuli zoipa.

Tikanena zosiyanasiyana lymphoma, PET kuphunzira pa yokhulupirika sitingapeze m'malo. kafukufuku njira zina za kwambiri wolephera matenda PET, onse molondola ndi chokwanira, ndipo metastasis mlingo kudziwika.
