La mtima scankapena myocardial scintigraphy, ndi kujambula chithunzi zomwe zimakupatsani mwayi wowonera khalidwe la ulimi wothirira mtima by Mitsempha yamtima.

Magazi akamayenda bwino m’mitsempha imeneyi, monga ngati atatsekeka kapena kupapatiza, minofu ya mtima (myocardium) siilandira mpweya wokwanira. Izi zimabweretsa zovuta zingapo zomwe zingakhale zoopsa: kupweteka pachifuwa, kupuma movutikira, kapena kugunda kwamtima (ichi ndikulephera kwa mtima).

Scintigraphy ndi njira yojambula yomwe imaphatikizapo kupereka kwa wodwalayo tracer ya radioactive, yomwe imafalikira m'thupi kapena ziwalo kuti zifufuzidwe. Choncho, ndi wodwala amene "amatulutsa" ma radiation omwe adzatengedwe ndi chipangizo (mosiyana ndi radiography, kumene ma radiation amachokera ndi chipangizo). The scintigraphy imapangitsa kuti zitheke kuwona momwe ziwalo zikuyendera (osati ma morphology awo okha).

Mayesowa amagwiritsidwa ntchito pozindikira matenda a mitsempha yamagazi.

M'nkhaniyi, ndizofanana kuchita masewera olimbitsa thupi (echocardiography).

Imathandizanso kuti:

• perekani malangizo kwa dokotala za mmene mtima ukugwirira ntchito, mmene umapopa kapena kutulutsa magazi
• kukayezetsa mtima pambuyo pa a m'mnyewa wamtima infarction kuti muwonetsetse madera aischemia(omwe achotsedwa mpweya) kapena kufunafuna malowa ngati pali kukayikiraangina orKulephera kwa Mtima
• kuunika kuopsa kwa mavuto amtima amtsogolo, mwachitsanzo asanachite opaleshoni, makamaka kwa anthu omwe ali ndi chiopsezo (shuga, matenda oopsa, kusuta, etc.) ndi omwe sangathe kuchita masewera olimbitsa thupi EKG

Dziwani kuti mitundu ingapo ya ma scintigraphies amtima imatha kuchitidwa pakuwunika kwamtima:

• myocardial perfusion scintigraphy
• Isotope ventriculography kapena synchronized angiocardioscintigraphy (MUGA), yomwe imapereka zambiri zokhudzana ndi kutulutsa mtima ndi kupopera.

La myocardial perfusion scintigraphy zimachitika pambuyo kuyesetsa. Zowonadi, kusakwanira kwa magazi pakachitika zovuta pamlingo wa coronaries kumawoneka makamaka panthawi yoyeserera.

Ndi contraindicated kwa amayi apakati kapena akuyamwitsa. Kusala kudya sikofunikira, koma mutha kulangizidwa kuti musamadye zolimbikitsa (khofi, tiyi, ndi zina zotero) patsiku la mayeso.

Nthawi zambiri, mudzafunsidwa kuyesa njinga kapena treadmill poyamba, moyang'aniridwa ndi katswiri wamtima. Ngati mayesowa akutsutsana, dokotala wanu adzakubayani mankhwala omwe amalimbikitsa mtima ngati mukuchita masewera olimbitsa thupi (dipyridamole, adenosine, dobutamine).

Mkati kapena mwamsanga pambuyo pa kuyezetsa, mankhwala ofooka a radioactive (radiotracer) amabayidwa mumtsempha wapamphumi, womwe umamangiriza ku mlingo wa mtima.

Mukangochita khama, ndiye panthawi yochira 15 mpaka mphindi 30 mutatha jekeseni wa radiotracer, mudzafunsidwa kuti mugone patebulo loyesa, pansi pa kamera yapadera (kamera ya scintillation) yomwe imakupatsani mwayi wowonera ma radiation opangidwa ndi moyo.

Malingana ndi zotsatira zoyamba zomwe tapeza, tikhoza kutenga zithunzi zatsopano 3 mpaka maola 4 pambuyo poyesa koyamba, popuma.

The scintigraphy imapangitsa kuti zitheke kuwulula zolakwika m'magazi amtima, komanso kuwunika momwe zimagwirira ntchito, makamaka panthawi yoyeserera.

Kutengera ndi zotsatira, dokotala wamtima adzapereka chithandizo choyenera ndikutsata kuti achepetse kuopsa kwa mtima.

Mayeso ena akhoza kuyitanidwa.
