Ubongo PET scan

Uropi positron emission tomography (PET) scan ndeyekufungidzira kuyedza kwehuropi. Inoshandisa radioactive chinhu chinonzi tracer kutsvaga chirwere kana kukuvara muuropi.

PET scan inoratidza mashandiro ari kuita huropi nematishu ayo. Mimwe miedzo yekufungidzira, yakadai semagineti resonance imaging (MRI) uye computed tomography (CT) zviyero zvinongoratidzira chimiro chehuropi.

PET scan inoda shoma radioactive zvinhu (tracer). Iyi tracer inopihwa kuburikidza netsinga (IV), kazhinji iri mukati megokora rako. Kana, iwe unofema mune radioactive zvinhu segesi.

Iyo inoteedzera inofamba kuburikidza neropa rako uye inounganidza mune nhengo uye matukisi. Anoteedzera anobatsira mupi wako wezvehutano kuti aone dzimwe nzvimbo kana zvirwere zvakajeka.

Iwe unomirira padhuze sezvo tracer inosvirwa nemuviri wako. Izvi zvinowanzotora inenge 1 awa.

Ipapo, unovata patafura yakatetepa, iyo inotsvedza kupinda mune yakakura tunnel-yakaita scanner. Iyo PET scanner inoona zviratidzo kubva kunoteedzera. Komputa inochinja mhedzisiro kuva 3-D mifananidzo. Mifananidzo yacho inoratidzwa pane yekutarisa kuti mupi wako averenge.

Unofanira kunyepera kunyarara panguva yekuyedzwa kuitira kuti muchina ubudise mifananidzo yakajeka yehuropi hwako. Iwe unogona kukumbirwa kuverenga kana kutumidza mavara kana yako ndangariro iri kuyedzwa.

Muedzo unotora pakati pemaminitsi makumi matatu nemaawa maviri.

Iwe unogona kubvunzwa kuti usadya chero chinhu kwemaawa mana kusvika matanhatu usati scan. Uchakwanisa kunwa mvura.

Udza mupiki wako kana:

• Iwe unotya nzvimbo dzepedyo (une claustrophobia). Unogona kupihwa mushonga wekukubatsira kuti unzwe kurara uye usanyanya kunetseka
• Iwe uri nepamuviri kana kufunga kuti ungangove nepamuviri.
• Iwe une chero ma allergies ejekiseni dhayi (musiyano).
• Iwe watora insulin yeshuga. Iwe unozoda gadziriro yakasarudzika.

Nguva dzose udza mupi wako nezve mishonga yauri kutora, kusanganisira iyo yakatengwa pasina mushonga. Dzimwe nguva, mishonga inokanganisa bvunzo.

Iwe unogona kunzwa kubaya kwakapinza apo tsono ine tracer yakaiswa mutsinga yako.

PET scan haikonzeri kurwadziwa. Tafura yacho inogona kunge yakaoma kana kutonhora, asi unogona kukumbira gumbeze kana mutsago.

Intercom iri mumba inokutendera kuti utaure nemumwe munhu chero nguva.

Iko hakuna nguva yekudzoreredza, kunze kwekunge iwe ukapihwa mushonga wekuzorora.

Mushure mekuyedzwa, inwa mvura zhinji kuti ubudise chinoteedzera kunze kwemuviri wako.

PET scan inogona kuratidza saizi, chimiro, uye mashandiro ehuropi, saka chiremba wako anogona kuona kuti iri kushanda nemazvo sezvainofanirwa kuita. Inonyanya kushandiswa kana mimwe bvunzo, senge MRI scan kana CT scan, isingape ruzivo rwakakwana.

Bvunzo iyi inogona kushandiswa ku:

• Ongorora gomarara
• Gadzirira kuvhiyiwa pfari
• Batsira kuongorora dementia kana mimwe bvunzo nemiedzo isingapi ruzivo rwakakwana
• Udza musiyano uripo pakati pechirwere chePasinson nezvimwe zvinetso zvekufamba

Akawanda maPET scans anogona kutorwa kuti uone kuti uri kupindura zvakadii kurapwa kwekenza kana chimwe chirwere.

Iko hakuna matambudziko anoonekwa muhukuru, chimiro, kana mashandiro ehuropi. Iko hakuna nzvimbo uko iyo tracer yakaunganidza zvisina kujairika.

Mhedzisiro isina kujairika inogona kunge iri nekuda kwe:

• Alzheimer chirwere kana kuora mwoyo
• Brain bundu kana kupararira kwegomarara kubva kune imwe nzvimbo yemuviri kuenda kuuropi
• Pfari, uye inogona kuziva panotangira kubatwa nepfungwa dzako
• Matambudziko ekufambisa (akadai sePasinson chirwere)

Huwandu hwemwaranzi hunoshandiswa muPET scan hwakaderera. Iyo inenge yakaenzana chiyero chemwaranzi senge mune akawanda maCT scans. Zvakare, mwaranzi haigare kwenguva refu mumuviri wako.

Vakadzi vane nhumbu kana vari kuyamwisa vanofanirwa kuzivisa mupi wavo ruzivo vasati vaita bvunzo iyi.Vacheche nevacheche vari kukura mudumbu vanonyanya kufunga nezvekukanganiswa nemwaranzi nekuti nhengo dzavo dzichiri kukura.

Izvo zvinogoneka, kunyangwe zvisingaite, kuve neanogadzirisa maitiro kune iyo radioactive chinhu. Vamwe vanhu vane marwadzo, kutsvuka, kana kuzvimba panzvimbo yejekiseni.

Izvo zvinokwanisika kuve nemhedzisiro mhedzisiro pane PET scan. Ropa shuga kana insulin mazinga anogona kukanganisa mhedzisiro yekuedzwa kune vanhu vane chirwere cheshuga.

PET scans inogona kuitwa pamwe neCT scan. Iyi yekubatanidza scan inonzi PET / CT.
