Kodi kusanthula mtima kwa PET ndi chiyani?

Kujambula kwa mtima kwa positron emission tomography (PET) ndiyeso yojambula yomwe imagwiritsa ntchito utoto wapadera kuti dokotala wanu awone zovuta ndi mtima wanu.

Utoto umakhala ndi ma tracer tracers, omwe amakhala m'malo amtima omwe angavulazidwe kapena kudwala. Pogwiritsa ntchito makina a PET, dokotala wanu amatha kuwona izi.

Kujambula mtima kwa PET nthawi zambiri kumakhala kuchipatala, kutanthauza kuti simudzakhala kuchipatala usiku wonse. Izi ndizomwe zimachitika tsiku limodzi.

Chifukwa chomwe kuyesa mtima kwa PET kwachitika

Dokotala wanu akhoza kuyitanitsa mtima wa PET ngati mukukumana ndi zofooka zamtima. Zizindikiro za vuto la mtima ndizo:

• kugunda kwamtima kosafunikira (arrhythmia)
• kupweteka pachifuwa
• zolimba m'chifuwa chanu
• kuvuta kupuma
• kufooka
• thukuta kwambiri

Dokotala wanu amathanso kuyitanitsa mtima wa PET ngati mayeso ena amtima, monga echocardiogram (ECG) kapena kupsinjika kwa mtima, samamupatsa dokotala chidziwitso chokwanira. Kujambula mtima kwa PET kungagwiritsidwenso ntchito kuwunika momwe chithandizo chamankhwala amtima chimathandizira.

Kuopsa kwakusanthula mtima kwa PET

Ngakhale sikani imagwiritsa ntchito ma tracer tracers, kuwonekera kwanu sikokwanira. Malinga ndi American College of Radiology Imaging Network, kuchuluka kwazowonekera ndikotsika kwambiri kuti kusakhudze momwe thupi lanu limayendera ndipo sikuwoneka ngati chiwopsezo chachikulu.

Zowopsa zina zakuyesa mtima kwa PET ndi izi:

• malingaliro osasangalatsa ngati ndinu claustrophobic
• kupweteka pang'ono kuchokera pobaya singano
• kupweteka kwa minofu poyikapo patebulo lolimba

Phindu la mayeserowa limaposa chiopsezo chochepa kwambiri.

Komabe, ma radiation atha kukhala owopsa kwa mwana wosabadwa kapena wakhanda. Ngati mukukayikira kuti muli ndi pakati, kapena mukuyamwitsa, adokotala angakulimbikitseni mtundu wina woyesedwa.

Momwe mungakonzekerere mtima wa PET

Dokotala wanu adzakupatsani malangizo athunthu okonzekera mtima wanu PET. Uzani dokotala wanu za mankhwala omwe mungamwe, kaya ndi mankhwala, owerengetsa, kapenanso zowonjezera zakudya.

Mutha kulangizidwa kuti musadye chilichonse kwa maola asanu ndi atatu musanachite. Mudzatha kumwa madzi.

Ngati muli ndi pakati, khulupirirani kuti mutha kukhala ndi pakati, kapena mukuyamwitsa, uzani dokotala wanu. Mayesowa atha kukhala osatetezeka kwa mwana wanu wosabadwa kapena woyamwa.

Muyeneranso kuuza dokotala za matenda aliwonse omwe muli nawo. Mwachitsanzo, ngati muli ndi matenda ashuga, mungafunike malangizo apadera kuti mukayesedwe, chifukwa kusala kudya pasadakhale kungakhudze kuchuluka kwa shuga wamagazi.

Musanayesedwe, mutha kupemphedwa kuti musinthe zovala zanu zachipatala ndikuchotsa zodzikongoletsera zanu zonse.

Momwe kuwunika kwa mtima kwa PET kumachitikira

Choyamba, mudzakhala pampando. Katswiri amapangira IV m'manja mwanu. Kudzera mu IV iyi, utoto wapadera wokhala ndi ma tracer tracers udzajambulidwa m'mitsempha yanu. Thupi lanu limafunikira nthawi kuti mumange ma tracers, chifukwa chake mudikirira pafupifupi ola limodzi. Panthawiyi, katswiri adzalumikiza maelekitirodi a electrocardiogram (ECG) pachifuwa panu kuti mtima wanu uwone.

Kenako, mudzakhala ndi jambulani. Izi zimaphatikizapo kugona patebulo lopapatiza lomwe limalumikizidwa ndi makina a PET. Gome lidzayenda pang'onopang'ono komanso mosalala mumakina. Muyenera kunama mwakachetechete momwe mungathere poyang'ana. Nthawi zina, katswiri amakupemphani kuti musasunthike. Izi zimalola zithunzi zomveka bwino kuti zizitengedwa.

Zithunzi zolondola zitasungidwa mu kompyuta, mudzatha kutuluka pamakina. Katswiriyo amachotsa maelekitirodi, ndipo mayeso adzatha.

Pambuyo pofufuza mtima wa PET

Ndibwino kumwa zakumwa zambiri pambuyo poyesedwa kuti zithandizire kutulutsa ma tracers m'dongosolo lanu. Nthawi zambiri, ma tracers onse amatuluka mthupi mwanu pakatha masiku awiri.

Katswiri wophunzitsidwa kuwerenga zowunikira za PET amatanthauzira zithunzi zanu ndikugawana zambiri ndi adotolo. Dokotala wanu adzakambiraninso zotsatira zanu pamsonkhano wotsatira.

Zomwe PET scan ingapeze

Kujambula mtima kwa PET kumamupatsa dokotala chithunzi chatsatanetsatane cha mtima wanu. Izi zimawathandiza kuti awone madera amtima omwe akukumana ndi kuchepa kwa magazi ndi madera ati omwe awonongeka kapena ali ndi minofu yofiira.

Matenda a Coronary (CAD)

Pogwiritsa ntchito zithunzizi, dokotala wanu amatha kudziwa matenda amitsempha yamagazi (CAD). Izi zikutanthauza kuti mitsempha yomwe imanyamula magazi ndi mpweya pamtima panu yaumitsidwa, kuchepa, kapena kutsekedwa. Akhozanso kuyitanitsa angioplasty kapena kuyika kwa stents kukulitsa mtsempha wamagazi ndikuchepetsa kuchepa kulikonse.

Angioplasty imaphatikizapo kuyika katheteti kakang'ono (chubu lofewa) chokhala ndi buluni kumapeto kwake kudzera mumitsempha yamagazi mpaka ikafika pamitsempha yochepetsetsa. Catheter ikakhala pamalo omwe mukufuna, dokotala wanu adzakhuta buluni. Izi zibaluni zidzakanikiza chikwangwani (chomwe chimayambitsa kutsekeka) motsutsana ndi khoma lamitsempha. Magazi amatha kuyenda bwinobwino kudzera mumtsempha.

M'milandu yoopsa kwambiri ya CAD, opareshoni yodutsitsa mitembo idzalamulidwa. Kuchita opaleshonoku kumaphatikizapo kuphatikiza gawo la mtsempha kuchokera mwendo wanu kapena mtsempha kuchokera pachifuwa kapena dzanja lanu kupita kumtunda wamagazi pamwambapa ndi pansi pa malo ochepera kapena otsekedwa. Mitsempha kapena mitsempha yatsopanoyi imalola magazi "kudutsa" mtsempha wowonongeka.

Mtima kulephera

Kulephera kwa mtima kumapezeka ngati mtima sungathenso kupereka magazi okwanira mthupi lanu lonse. Vuto lalikulu la matenda amitsempha yamtumbo nthawi zambiri limayambitsa.

Kulephera kwa mtima kumayambitsanso:

• matenda a mtima
• matenda obadwa nawo amtima
• matenda amtima
• matenda a valavu ya mtima
• mitima yachilendo (arrhythmias)
• matenda monga emphysema, chithokomiro chopitilira muyeso kapena chosagwira ntchito, kapena kuchepa magazi m'thupi

Pankhani ya kulephera kwa mtima, dokotala wanu amatha kukupatsani mankhwala kapena kuchititsa opaleshoni. Amatha kuyitanitsa angioplasty, opaleshoni yodutsitsa, kapena opaleshoni yamagetsi yamtima. Dokotala wanu angafunenso kuyika pacemaker kapena defibrillator, zomwe ndi zida zomwe zimapangitsa kugunda kwamtima nthawi zonse.

Kutengera ndi zomwe mwapeza, dokotala akhoza kuyankhula nanu za kuyezetsa ndi chithandizo china.
