Mwoyo PET scan

Yemoyo positron emission tomography (PET) scan muyedzo wekufungidzira unoshandisa radioactive chinhu chinonzi tracer kutsvaga chirwere kana kushomeka kweropa kuyerera mumoyo.

Kusiyana nemagineti resonance imaging (MRI) uye computed tomography (CT), iyo inoratidza chimiro cheropa kuyerera ichienda uye kubva kune nhengo, PET scan inopa rumwe ruzivo nezve mashandiro emitezo nematumbu.

Mwoyo PET scan inogona kuona kana nzvimbo dzemutsipa wako wemwoyo dziri kugamuchira ropa rakaringana, kana paine kukuvara kwemoyo kana zvinyama zvitsvuku mumoyo, kana kana paine kuwanda kwezvinhu zvisina kujairika mumhasuru yemoyo.

PET scan inoda shoma radioactive zvinhu (tracer).

• Iyi tracer inopihwa kuburikidza netsinga (IV), kazhinji kazhinji mukati megokora rako.
• Iyo inofamba kuburikidza neropa rako uye inounganidza mune nhengo uye zvinyama, kusanganisira moyo wako.
• Iyo inoteedzera inobatsira iyo radiologist kuona dzimwe nzvimbo kana zvirwere zvakajeka.

Iwe unozofanira kumirira padhuze sezvo tracer inosvirwa nemuviri wako. Izvi zvinotora ingangoita 1 awa kazhinji.

Ipapo, iwe ucharara pamusoro petafura yakatetepa, iyo inotsvedza kupinda mune yakakura tunnel-yakaita scanner.

• Electrodes ye electrocardiogram (ECG) ichaiswa pachipfuva chako. Iyo PET scanner inoona zviratidzo kubva kunoteedzera.
• Komputa inochinja mhedzisiro kuva 3-D mifananidzo.
• Mifananidzo yacho inoratidzwa pane yekutarisa kuti radiologist iverenge.

Unofanira kunyepera kunyarara panguva yePET scan kuti muchina ubudise mifananidzo yakajeka yemoyo wako.

Dzimwe nguva, iyo bvunzo inoitwa pamwe pamwe nekunetseka kuyedzwa (kurovedza muviri kana pharmacologic kushushikana).

Muedzo unotora maminetsi makumi mapfumbamwe.

Iwe unogona kubvunzwa kuti usadya chero chinhu kwemaawa mana kusvika matanhatu usati scan. Uchakwanisa kunwa mvura. Dzimwe nguva unogona kupihwa chikafu chakakosha usati waedzwa.

Udza mupi wako wezvehutano 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 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. 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.

Moyo PET scan inogona kuratidza saizi, chimiro, chinzvimbo, uye kumwe kushanda kwemoyo.

Iyo inowanzo shandiswa kana kumwe kuyedzwa, senge echocardiogram (ECG) uye nemoyo kushushikana bvunzo hakupi ruzivo rwakakwana.

Muedzo uyu unogona kushandiswa kuongorora matambudziko emoyo uye kuratidza nzvimbo mune kusarongeka kweropa kuyerera kumoyo.

Akawanda maPET scans anogona kutorwa mukufamba kwenguva kuti uone kuti uri kupindura sei pakurapwa kwechirwere chemwoyo.

Kana bvunzo yako yaisanganisira kurovedza muviri, bvunzo yakajairwa kazhinji inoreva kuti iwe wakakwanisa kurovedza muviri kwenguva yakareba kana yakareba kupfuura vanhu vazhinji vezera rako nebonde. Iwewo hauna zviratidzo kana shanduko mukumanikidza kweropa kana ECG yako yakakonzera kunetsekana.

Iko hakuna matambudziko anoonekwa muhukuru, chimiro, kana mashandiro emoyo. Iko hakuna nzvimbo uko iyo radiotracer yakaunganidzwa zvisina kujairika.

Mhedzisiro isina kujairika inogona kunge iri nekuda kwe:

• Coronary tsinga chirwere
• Kutadza kwemoyo kana cardiomyopathy

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.

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

Mazhinji emaketi ePET ave kuitwa pamwe neCT scan. Iyi yekubatanidza scan inonzi PET / CT.
