PET scan yekenza yemazamu

A positron emission tomography (PET) scan muyedzo wekufungidzira unoshandisa radioactive chinhu (inonzi tracer) kutsvaga zvinogona kupararira zvecancer yemazamu. Iyi tracer inogona kubatsira kuziva nzvimbo dzegomarara idzo MRI kana CT scan inogona kusaratidza.

PET scan inoda shoma radioactive zvinhu (tracer). Iyi tracer inopihwa kuburikidza netsinga (IV), kazhinji iri mukati megokora rako, kana mune tsinga diki iri muruoko rwako. Anoteverera anofamba kuburikidza neropa rako uye anounganidza munhengo uye nyama uye anopa chiratidzo chinobatsira radiologist kuona dzimwe nzvimbo kana chirwere zvakajeka.

Iwe unozofanira kumirira padhuze sezvo muviri wako unotora unoteedzera. Izvi zvinowanzotora inenge 1 awa.

Ipapo, iwe ucharara pamusoro petafura yakatetepa, iyo inotsvedza kupinda mune yakakura tunnel-yakaita scanner. Iyo PET scanner inoona zviratidzo zvinopihwa kubva kune iyo tracer. Komputa inoshandura zvabuda kuita mifananidzo ye3D. Mifananidzo yacho inoratidzwa pane yekutarisa kuti chiremba wako adudzire.

Unofanira kunyepera kunyarara panguva yekuedzwa. Kufamba kwakawandisa kunogona kukanganisa mifananidzo uye kukonzera zvikanganiso.

Muedzo unotora maminetsi makumi mapfumbamwe.

Mazhinji maPET scans anoitwa pamwe neCT scan. Iyi yekubatanidza scan inonzi PET / CT.

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

Udza mupi wako wezvehutano kana:

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

Nguva dzose udza mupi wako nezve mishonga yauri kutora, kusanganisira iyo yakatengwa pasina mushonga. Dzimwe nguva, mishonga inogona kukanganisa mhedzisiro yekuedzwa.

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

PET scan haikonzeri kurwadziwa. Imba netafura zvinogona 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.

PET scan inowanzo shandiswa kana kumwe kuyedzwa, senge MRI scan kana CT scan, USAPA ruzivo rwakakwana kana vanachiremba vari kutsvaga izvo zvinogona kupararira zvecancer yemazamu kune lymph node kana kupfuura.

Kana iwe uine kenza yemazamu, chiremba wako anogona kuraira iyi scan:

• Nguva pfupi mushure mekuongororwa kwako kuti uone kana gomarara rapararira
• Mushure mekurapwa kana paine kunetsekana kuti gomarara radzoka
• Panguva yekurapwa kuti uone kana gomarara riri kupindura kurapwa

PET scan haina kushandiswa kuongorora, kana kuongorora, kenza yemazamu.

Mhedzisiro mhedzisiro zvinoreva kuti hapana nzvimbo dziri kunze kwezamu umo radiotracer yakaunganidzwa zvisina kujairika. Mhedzisiro iyi inogona kureva kuti gomarara repazamu harina kupararira kune dzimwe nhengo dzemuviri.

Nzvimbo diki kwazvo dzekenza yemazamu dzinogona kusaratidza pane PET scan.

Mhedzisiro isina kujairika inogona kureva kuti gomarara repazamu rinogona kunge rakapararira kunze kwezamu.

Ropa shuga kana insulin mwero inogona kukanganisa mhedzisiro yekuedzwa kune vanhu vane chirwere cheshuga.

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

Vakadzi vane pamuviri kana kuyamwisa vanofanira kuzivisa chiremba wavo vasati vaita bvunzo iyi. Vacheche nevacheche vari kukura mudumbu vanonyanya kufunga nezvekukanganiswa nemwaranzi nekuti nhengo dzavo dzichiri kukura.

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

Mushure mokunge scan ichiitwa, unogona kukumbirwa kunwa mvura yakawanda uye kugara kure nevana vari pasi pemakore gumi nematatu kana chero munhu ane nhumbu kwemaawa makumi maviri nemana.

Kana iwe uchiyamwisa, udza chiremba wako. Chiremba wako anogona kukurudzira kuti iwe usamwisa mwana kwemaawa makumi maviri nemana mushure mekuongororwa.
