Tiyeni tiphunzire za MUGA Scan, yomwe imafufuza momwe mtima umagwirira ntchito.

Ganizirani mtima wanu ngati pompu yamadzi. Ntchito yake yayikulu ndikupompa magazi m'thupi lonse. Chifukwa chake, mayeso apadera omwe amayesa momwe mtima ukugwirira ntchito, ndiko kuti, momwe mtima ukugwirira ntchito bwino, amatchedwa MUGA scan. Dzinali likhoza kukhala latsopano kwa inu. Chifukwa chake lero, tiyeni tikambirane za izi mosavuta, mwanjira yomwe mungamvetse.

Kodi MUGA scan ndi chiyani?

Mwachidule, MUGA scan ndi mayeso apadera owunikira, kapena kuyeza molondola, momwe mtima wanu ukupopera magazi. Zimaphatikizapo kubaya pang'ono kwambiri mankhwala owopsa otchedwa ``radionuclide'' mumtsempha wanu umodzi. Kenako, pogwiritsa ntchito kamera yapadera, zithunzi za mtima wanu zimatengedwa pamene chinthuchi chikuyenda mumtima mwanu ndi magazi anu.

Mayeso awa angakupatseni chithunzi chomveka bwino cha momwe minofu ya mtima wanu imagwirira ntchito komanso kupumula mukapuma komanso panthawi yochita masewera olimbitsa thupi. Mayina ena a mayesowa ndi `radionuclide ventriculography (RNVG)` ndi `equilibrium radionuclide angiocardiography (ERNA)`.

Kodi scan iyi ikusonyeza chiyani kwenikweni?

Chinthu chachikulu chomwe chimayesedwa ndi gawo lanu la Ejection Fraction (EF) . Tsopano mwina mukudabwa kuti EF imatanthauza chiyani.

Tangoganizirani mtima wanu ukudzaza ndi magazi, kenako umafinya (kufinya) ndikupopera magaziwo m'thupi. Chomwe timachitcha EF ndi kuchuluka kwa magazi onse omwe ali mumtima omwe amapopedwa panthawi iliyonse yopuma.

Mwachitsanzo, ngati EF yanu ndi 70%, zikutanthauza kuti mtima wanu ukadzaza ndi magazi ndikupopa kamodzi, umapopa 70% ya kuchuluka kwa magazi onse kupita ku thupi. EF ya munthu wathanzi ndi yabwinobwino pakati pa 50% ndi 75%.

Kodi MUGA scan imafunika liti?

Dokotala wanu angakulangizeni mayesowa ngati muli ndi zizindikiro za kulephera kwa mtima. Kulephera kwa mtima ndi pamene mtima sungathe kupompa magazi bwino. Gome ili pansipa likuwonetsa zina mwa zizindikiro zomwe zingachitike panthawiyi.

Komanso, dokotala wanu angakupatseni mayesowa musanayambe kapena mutalandira chithandizo cha khansa. Izi zili choncho chifukwa mankhwala ena a khansa amatha kuwononga mtima. Ena mwa mankhwalawa ndi awa:

• Kusamutsa mafuta a m'mafupa
• Mankhwala a Chemotherapy
• Chithandizo cha Immunotherapy
• Chithandizo cha radiation pachifuwa

Kodi kusiyana pakati pa MUGA scan ndi Echo test ndi kotani?

Mayeso onsewa amapereka chidziwitso chokhudza momwe mtima umagwirira ntchito, koma njira zake ndi zosiyana.

• Echocardiogram: Kuyeza kumeneku kumagwiritsa ntchito mafunde a phokoso, mofanana ndi ultrasound scan ya mwana wa mayi wapakati. Dokotala amajambula zithunzi pamene akusuntha chipangizo chapadera (transducer) pachifuwa panu.
• MUGA scan: Iyi ndi mayeso ojambulira zinthu za nyukiliya. Imagwiritsa ntchito chowunikira cha radioactive.

Kodi muyenera kukonzekera bwanji musanayese mayeso?

Dokotala wanu adzakupatsani malangizo enieni musanayesedwe. Ndikofunikira kwambiri kutsatira malangizo amenewo molondola. Kawirikawiri, awa ndi awa:

• Pewani kudya kapena kumwa kwa maola pafupifupi asanu ndi limodzi musanayesedwe.
• Pewani kumwa caffeine (khofi, tiyi, zakumwa zoziziritsa kukhosi) kwa maola angapo musanayesedwe, chifukwa caffeine ikhoza kukweza kugunda kwa mtima wanu ndikukhudza zotsatira za mayeso.
• Uzani dokotala wanu za mankhwala onse omwe mukumwa . Mankhwala ena a mtima (monga nitrates kapena digoxin) angafunike kuyimitsidwa tsiku limodzi kapena awiri mayeso asanachitike.

Kodi chimachitika ndi chiyani panthawi ya mayeso?

Ntchito yonseyi ingatenge ola limodzi mpaka atatu. Panthawiyi, mudzagona patebulo loyezera ndipo kamera yapadera idzayikidwa pachifuwa panu. Kenako, katswiri adzatsatira izi:

1. Ma electrode angapo (zomata ngati zomwe zimagwiritsidwa ntchito pa ECG) adzaikidwa pachifuwa panu. Izi zidzayesa momwe magetsi a mtima wanu amagwirira ntchito.

2. Mankhwala owopsa omwe atchulidwa kale ``(radiotracer)`` amalowetsedwa mu imodzi mwa mitsempha yanu.

3. Kamera imajambula zithunzi za mtima wanu kuchokera mbali zosiyanasiyana.

Nthawi zina, mudzapemphedwa kuchita masewera olimbitsa thupi pamene zithunzi zikujambulidwa. Mwachitsanzo , kuyenda pa treadmill . Izi zimachitika kuti muwone momwe mtima wanu umayankhira kupsinjika.

Kodi chimachitika ndi chiyani pambuyo pa mayeso?

Nkhani yabwino ndi yakuti mutha kuyambiranso ntchito zanu zachizolowezi, kuphatikizapo kuyendetsa galimoto, mayeso akangotha. Koma kumbukirani chinthu chimodzi: Imwani madzi ambiri, kuphatikizapo madzi , kwa tsiku limodzi kapena awiri mutatha mayeso. Izi zithandiza kuti zinthu zotulutsa ma radiation zichoke m'thupi lanu mwachangu.

Kodi pali chiopsezo chilichonse pa izi?

Kujambula MUGA ndi njira yotetezeka kwambiri kwa anthu ambiri. Kuchuluka kwa zinthu zowononga ma radiation zomwe zimalowetsedwa m'thupi ndi kochepa kwambiri, kotero sikoopsa. Ndipo nthawi zambiri zimachotsedwa kwathunthu m'thupi mkati mwa maola 24.

Komabe, ngati muli ndi pakati, mukuganiza kuti muli ndi pakati, kapena mukuyamwitsa, muyenera kuuza dokotala wanu za izi , chifukwa mayesowa nthawi zambiri salimbikitsidwa pazochitika zotere.

Zinthu zoti mufunse dokotala wanu

Ngati muli ndi mafunso ena okhudza mayesowa, musaope kufunsa dokotala wanu. Mutha kufunsa zinthu monga:

• Nchifukwa chiyani ndikufunika MUGA scan?
• Kodi mayesowa amatenga nthawi yayitali bwanji?
• Kodi pali chilichonse chomwe ndiyenera kuchita kuti ndikonzekere mayesowa?
• Kodi ubwino wa mayesowa ndi wotani?
• Kodi lipoti la kafukufuku likuti chiyani?
• Kodi ndichite chiyani pambuyo pa mayeso awa?
