Mapapu PET scan

Yemapapu positron emission tomography (PET) scan muyedzo wekufungidzira. Iyo inoshandisa radioactive chinhu (inonzi tracer) kutsvaga chirwere mumapapu senge kenza yemapapu.

Kusiyana nemagineti resonance imaging (MRI) uye macomputer tomography (CT) scan, iyo inoratidza chimiro chemapapu, PET scan inoratidza mashandiro anoita mapapu nematishu awo.

PET scan inoda shoma yekuteedzera. Iyo yekuteedzera inopihwa kuburikidza netsinga (IV), kazhinji iri mukati megokora rako. Iyo inofamba kuburikidza neropa rako uye inounganidza mune nhengo uye zvinyama. Iyo inoteedzera inobatsira chiremba (radiologist) kuona dzimwe nzvimbo kana zvirwere zvakajeka.

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

Ipapo, iwe ucharara pamusoro petafura 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 chiremba wako averenge.

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

Muedzo unotora maminetsi makumi mapfumbamwe.

PET scans inoitwa pamwe neCT scan. Izvi zvinodaro nekuti ruzivo rwakasanganiswa kubva pasikana yega yega runopa kunzwisisa kwakazara kwedambudziko rehutano. 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 dzakamanikana (une claustrophobia). Iwe unogona kupihwa mushonga wekukubatsira iwe kuzorora uye kunzwa kushoma kunetseka.
• Iwe uri nepamuviri kana kufunga kuti ungangove nepamuviri.
• Iwe une chero ma allergies ejekiseni dhayi (musiyano).
• Iwe unotora insulin yeshuga. Iwe unozoda gadziriro yakasarudzika.

Udza mupiki wako nezve mishonga yauri kutora. Izvi zvinosanganisira izvo zvakatengwa zvisina mushonga. Mimwe mishonga inogona kukanganisa mhedzisiro yekuedzwa.

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.

Bvunzo iyi inogona kuitwa ku:

• Batsira kutarisa kenza yemapapu, kana imwe bvunzo yekufungidzira isingape yakajeka mufananidzo
• Ona kana gomarara remapapu rapararira kune dzimwe nzvimbo dzemapapu kana muviri, kana uchifunga nezvekurapa kwakanyanya
• Batsira kuona kana kukura mumapapu (kunoonekwa paCT scan) kune gomarara kana kwete
• Sarudza kuti kurapa kenza kuri kushanda sei

Mhedzisiro mhedzisiro zvinoreva kuti scan haina kuratidza chero matambudziko muhukuru, chimiro, kana mashandiro emapapu.

Mhedzisiro isina kujairika inogona kunge iri nekuda kwe:

• Kenza yemapapu kana gomarara reimwe nzvimbo yemuviri yakapararira kumapapu
• Utachiona
• Kuzvimba kwemapapu nekuda kwezvimwe zvikonzero

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