MRI ya Mtima

Kujambula kwa maginito amtima ndi njira yojambulira yomwe imagwiritsa ntchito maginito amphamvu ndi mafunde amawu kuti apange zithunzi za mtima. Sigwiritsa ntchito radiation (x-ray).

Zithunzi zamtundu umodzi zamaginito (MRI) zimatchedwa magawo. Zithunzizo zimatha kusungidwa pakompyuta kapena kusindikizidwa pafilimu. Kuyesa kumodzi kumatulutsa zithunzi zambiri kapena nthawi zina mazana.

Mayesowa amatha kuchitidwa ngati chifuwa cha MRI.

Mutha kupemphedwa kuvala chovala chaku chipatala kapena chovala chopanda zomangira zachitsulo (monga thukuta ndi t-sheti). Mitundu ina yazitsulo imatha kuyambitsa zithunzi zolakwika kapena kukopeka ndi maginito amphamvu.

Mudzagona pa tebulo laling'ono, lomwe limalowa mu chubu chachikulu ngati ngalande.

Mayeso ena amafuna utoto wapadera (kusiyanitsa). Utoto umaperekedwa nthawi zambiri musanayezedwe kudzera mumitsempha (IV) yomwe ili m'manja mwanu. Utoto umathandiza radiologist kuwona madera ena bwino lomwe. Izi ndizosiyana ndi utoto womwe umagwiritsidwa ntchito pa CT scan.

Pa MRI, munthu amene amagwiritsa ntchito makinawo amakuwonerani kuchokera kuchipinda china. Mayeso nthawi zambiri amatenga mphindi 30 mpaka 60 koma amatenga nthawi yayitali.

Mutha kupemphedwa kuti musadye kapena kumwa chilichonse kwa maola 4 kapena 6 musanajambulitse.

Uzani wothandizira zaumoyo wanu ngati mukuwopa malo oyandikira (khalani ndi claustrophobia). Mutha kupatsidwa mankhwala okuthandizani kuti mukhale ogona komanso osakhala ndi nkhawa, kapena omwe akukuthandizani atha kunena za MRI "yotseguka", pomwe makinawo sali pafupi ndi thupi.

Asanayesedwe, uzani omwe akukuthandizani ngati muli ndi:

• Zithunzi za ubongo
• Mitundu ina yamavavu amtima wopangira
• Mtetezi wamtima kapena pacemaker
• Zodzala zamakutu zamkati (cochlear)
• Matenda a impso kapena dialysis (mwina simungathe kusiyanitsa)
• Zowayika posachedwa
• Mitundu ina yamatenda am'mimba
• Ankagwira ntchito ndi chitsulo m'mbuyomu (mungafunike kuyesa kuti muwone ngati zidutswa zazitsulo zili m'maso mwanu)

Chifukwa MRI imakhala ndi maginito amphamvu, zinthu zachitsulo siziloledwa kulowa mchipindacho ndi sikani ya MRI:

• Zolembera, zotchinga matumba, ndi magalasi amaso zitha kuwuluka mchipinda chonse.
• Zinthu monga zodzikongoletsera, mawotchi, ma kirediti kadi, ndi zothandizira kumva zimatha kuwonongeka.
• Pini, zikhomo zopangira tsitsi, zipi zachitsulo, ndi zinthu zina zachitsulo zofananira zimatha kupotoza zithunzizi.
• Ntchito yochotsa mano iyenera kutulutsidwa pang'ono isanakwane.

Kuyezetsa mtima kwa MRI sikumapweteka. Anthu ena amatha kuda nkhawa akakhala mkati mwa sikani. Ngati zikukuvutani kugona kapena mukuda nkhawa kwambiri, mutha kupatsidwa mankhwala kuti musangalale. Kuyenda kwambiri kumatha kusokoneza zithunzi za MRI ndikupanga zolakwika.

Gome likhoza kukhala lolimba kapena lozizira, koma mutha kufunsa bulangeti kapena pilo. Makinawo amapanga phokoso lalikulu ndikumveketsa mukatsegulidwa. Mutha kupatsidwa mapulagi amve kuti athandizire kuchepetsa phokoso.

Intercom mu scanner imakupatsani mwayi wolankhula ndi munthu amene akuyeserera mayeso nthawi iliyonse. Makina ena a MRI ali ndi ma televizioni ndi mahedifoni apadera othandizira kupititsa nthawiyo.

Palibe nthawi yobwezeretsa, pokhapokha sedation ikakhala yofunikira. .

MRI imapereka zithunzi zambiri za mtima ndi mitsempha yamagazi kuchokera pamawonekedwe ambiri. Nthawi zambiri, imagwiritsidwa ntchito pakafunika kudziwa zambiri mutakhala ndi echocardiogram kapena mtima CT scan. MRI ndiyolondola kwambiri kuposa CT scan kapena mayeso ena pazinthu zina, koma siyolondola kwa ena.

Mtima MRI ungagwiritsidwe ntchito poyesa kapena kuzindikira:

• Kuwonongeka kwa minofu yamtima mutadwala mtima
• Zolephera zakubadwa za mtima
• Zotupa za mtima ndi zophuka
• Kuchepetsa kapena mavuto ena ndi minofu yamtima
• Zizindikiro za kulephera kwa mtima

Zotsatira zachilendo zitha kukhala chifukwa cha zinthu zambiri, kuphatikiza:

• Matenda a valavu yamtima
• Chamadzimadzi thumba ngati chophimba kuzungulira mtima (pericardial effusion)
• Chotupa cha mitsempha yamagazi kapena mozungulira mtima
• Atrial myxoma kapena kukula kwina kapena chotupa mumtima
• Matenda amtima obadwa nawo (vuto la mtima lomwe mudabadwa nalo)
• Kuwonongeka kapena kufa kwa minofu ya mtima, kuwonedwa atadwala mtima
• Kutupa kwa mtima waminyewa
• Kulowetsedwa kwa minofu ya mtima ndi zinthu zachilendo
• Kuchepa kwa minofu yamtima, yomwe imatha kuyambitsidwa ndi sarcoidosis kapena amyloidosis

Palibe radiation yomwe imakhudzidwa ndi MRI. Maginito ndi mawailesi omwe amagwiritsidwa ntchito panthawi yojambulira sanawonetsedwe kuti angayambitse zovuta zina.

Thupi lanu siligwirizana ndi utoto womwe umagwiritsidwa ntchito poyesa. Mtundu wosiyana kwambiri (utoto) womwe umagwiritsidwa ntchito ndi gadolinium. Ndi otetezeka kwambiri. Yemwe amagwiritsa ntchito makinawo amayang'anira kugunda kwa mtima wanu ndi kupuma kwanu pakufunika. Zovuta zambiri zimatha kuchitika kwa anthu omwe ali ndi mavuto a impso.

Anthu avulazidwa pamakina a MRI pomwe samachotsa zinthu zachitsulo zovala zawo kapenanso pamene zinthu zachitsulo zimasiyidwa mchipinda ndi ena.

MRI sikulimbikitsidwa nthawi zambiri kuvulala koopsa. Zonyamula ndi zida zothandizira moyo sizingaloŵe bwinobwino sikani.

Ma MRIs atha kukhala okwera mtengo, amatenga nthawi yayitali kuti achite, ndipo amazindikira kuyenda.
