Chii chinonzi moyo PET scan?

Iyo positron emission tomography (PET) scan yemoyo bvunzo yekufungidzira iyo inoshandisa dhayi yakasarudzika kubvumira chiremba wako kuti aone matambudziko nemoyo wako.

Iyo dhayi ine ma radioactive tracers, ayo anotarisana nenzvimbo dzemoyo dzinogona kukuvara kana kurwara. Uchishandisa PET scanner, chiremba wako anogona kuona idzi nzvimbo dzekunetseka.

Mwoyo PET scan inowanzo kuve yekurapa nzira, zvichireva kuti haufanire kugara muchipatara husiku hwese. Izvi zvinowanzoitika zvakafanana-zuva maitiro.

Nei moyo PET scan yaitwa

Chiremba wako anogona kuraira moyo PET scan kana uri kusangana nezviratidzo zvekunetseka kwemoyo. Zviratidzo zvekutambudzika kwemoyo zvinosanganisira:

• kusagadzikana kwemwoyo (arrhythmia)
• kurwadziwa mubhokisi rako
• kuomesa mubhokisi rako
• kunetseka kufema
• kushaya simba
• kudikitira zvakanyanya

Chiremba wako anogona zvakare kuraira moyo PET scan kana kumwe kuyedzwa kwemoyo, senge echocardiogram (ECG) kana bvunzo yemoyo, usape chiremba wako ruzivo rwakakwana. Mwoyo PET scan inogona zvakare kushandiswa kuteedzera kushanda kwehutano hwemwoyo kurapwa.

Njodzi dzemoyo PET scan

Kunyange iyo scan ichishandisa radioactive tracers, kuratidzwa kwako kushoma. Sekureva kweAmerican College yeRadiology Imaging Network, iyo yekuburitsa mwero yakanyanya kuderera kuti ikanganise maitiro akajairika emuviri wako uye haionekwe senjodzi huru.

Dzimwe njodzi dzemoyo PET scan dzinosanganisira:

• kusagadzikana manzwiro kana iwe uri claustrophobic
• kurwadziwa zvishoma kubva kubaya retsono
• mhasuru kusuruvara kubva pakuisa patafura yakaoma bvunzo

Aya mabhenefiti ebhenefiti anokunda zvakanyanya njodzi shoma.

Nekudaro, radiation inogona kukuvadza kune fetus kana mwana achangozvarwa. Kana iwe uchifungidzira kuti unogona kunge uine pamuviri, kana uri kuyamwisa, chiremba wako anogona kukurudzira imwe nzira yekuyedza.

Maitiro ekugadzirira kune moyo PET scan

Chiremba wako achakupa mirairo izere nezvekugadzirira moyo wako PET scan. Udza chiremba wako nezve chero mishonga yaunogona kutora, kunyangwe iri mishonga, pamusoro-pe-kontrakiti, kana kunyange zvinovaka muviri zvekuwedzera.

Iwe unogona kurairwa kuti usadya chero chinhu kwemaawa masere usati waita. Iwe unozogona, zvakadaro, kugona kunwa mvura.

Kana iwe uri nepamuviri, tenda kuti unogona kunge uine pamuviri, kana uri mukoti, udza chiremba wako. Bvunzo iyi inogona kunge isina kuchengetedzeka kumwana wako asati azvarwa kana anoyamwa.

Iwe unofanirwa zvakare kuudza chiremba wako nezve chero mamiriro ehutano aunawo. Semuenzaniso, kana uine chirwere cheshuga, ungangoda mirairo yakakosha yekuyedza, sezvo kutsanya pamberi kunogona kukanganisa mashuga eropa rako.

Pakarepo pamberi pekuyedzwa, unogona kubvunzwa kuti uchinje chipfeko chechipatara uye kubvisa zvishongo zvako zvese.

Maitiro emoyo PET scan anoitwa

Kutanga, iwe uchagara pachigaro. Nyanzvi inozoisa IV mumaoko ako. Kubudikidza neiyi IV, dhayi yakakosha ine ma radioactive tracers inojowa mutsinga dzako. Muviri wako unoda nguva yekumwa matare, saka unomirira ingangoita awa. Pakati peino nguva, nyanzvi inobatanidza maelekitirodhi eiyo electrocardiogram (ECG) pachipfuva chako kuitira kuti kurova kwemoyo wako kutariswe.

Tevere, iwe unozotarisana neiyo scan. Izvi zvinosanganisira kurara patafura yakatetepa yakasungirirwa kumuchina wePET. Tafura yacho ichatsvedza zvishoma nezvishoma uye zvakatsetseka mumuchina. Iwe uchafanirwa kunyepa zvakadzama sezvinobvira panguva yekuyera. Pane dzimwe nguva, nyanzvi inokuudza kuti urambe usingafambi. Izvi zvinobvumira iyo yakajeka mifananidzo kutorwa.

Mushure mekunge mifananidzo chaiyo yachengetwa mukombuta, iwe unozogona kutsvedza kubuda muchina. Nyanzvi inozobvisa ma electrode, uye bvunzo rapera.

Mushure memoyo PET scan

Ipfungwa yakanaka kunwa zvinwiwa zvakawanda mushure mekuyedzwa kubatsira kuburitsa ma tracers kubva muhurongwa hwako. Kazhinji, matracers ese akasununguka kubviswa mumuviri wako mushure memazuva maviri.

Nyanzvi yakadzidziswa kuverenga PET scans inodudzira mifananidzo yako uye nekugovana ruzivo nachiremba wako. Chiremba wako anozoenda pamusoro pemhedzisiro newe panguva yekutevera.

Iko moyo PET scan inogona kuwana

Mwoyo PET scan inopa chiremba wako mufananidzo wakadzama wemwoyo wako. Izvi zvinovatendera kuti vaone kuti ndedzipi nzvimbo dzemoyo dziri kusangana nekuderera kweropa uye ndedzipi nzvimbo dzakakuvara kana dzine zvinyama zvitsvuku.

Coronary arteri chirwere (CAD)

Uchishandisa iyo mifananidzo, chiremba wako anogona kuongorora coronary artery chirwere (CAD). Izvi zvinoreva kuti tsinga dzinoendesa ropa neoksijeni kumoyo wako dzave dzakaomarara, dzakapetwa, kana kuvharika. Ivo vanogona ipapo kuraira angioplasty kana kuiswa kwe stents kuwedzera arteri uye kubvisa chero kuderera.

Angioplasty inosanganisira kuisa catheter yakatetepa (chubhu nyoro) ine chibharumu pamucheto wayo kuburikidza nemudziyo weropa kudzamara yasvika kune yakatetepa, yakavharika tsinga. Kamwe iyo catheter iri munzvimbo yaunoda, chiremba wako anozadza bharumu. Iri bharumu richapurudzira chikwangwani (chinokonzera iko kuvharika) kurwisa artery madziro. Ropa rinogona kubva richiyerera zvakanaka kuburikidza netsinga.

Mune zvimwe zvakakomba zviitiko zveCAD, coronary bypass kuvhiyiwa kunozorayirwa. Kuvhiya uku kunosanganisira kubatanidza chikamu chetsinga kubva pagumbo rako kana tsinga kubva muchipfuva chako kana chiuno kusvika kune aronari kumusoro uye pasi penzvimbo yakatetepa kana yakavharika. Tsinga ichangobva kubatanidzwa kana tsinga inozobvumira ropa "kudarika" tsinga yakakuvadzwa.

Kutadza kwemoyo

Kukundikana kwemoyo kunoonekwa kana moyo usisakwanise kupa ropa rakaringana kune wese muviri wako. Chiitiko chakakomba checoronary artery chirwere chinowanzo kuve chikonzero.

Kukundikana kwemoyo kunogona kukonzerwa ne:

• cardiomyopathy
• kuberekwa chirwere chemoyo
• kumira kurova kwemoyo
• chirwere chevhavha yemoyo
• zvisina kujairika moyo mutinhimira (arrhythmias)
• zvirwere zvakadai semphysema, yakanyanyisa kushanda kana kusashanda kwetachiona, kana kupererwa neropa

Muchiitiko chekutadza kwemoyo, chiremba wako anogona kupa mishonga kana kuraira kuvhiya. Vanogona kuraira angioplasty, coronary bypass kuvhiyiwa, kana kuvhiyiwa moyo vharuvhu. Chiremba wako anogona zvakare kuda kuisa pacemaker kana defibrillator, zvinova zvishandiso zvinochengetedza kurova kwemoyo nguva dzose.

Zvichienderana nezvako mhedzisiro, chiremba wako anogona kutaura newe nezvekuenderera mberi nekuedzwa uye kurapwa.
