Kusanthula mtima kwa PET

Kujambula kwa mtima positron emission tomography (PET) ndiyeso yojambula yomwe imagwiritsa ntchito mankhwala a radioactive otchedwa tracer kufunafuna matenda kapena kusayenda bwino kwa magazi mumtima.

Mosiyana ndi kujambula kwa maginito (MRI) ndi computed tomography (CT), komwe kumawululira momwe magazi amayendera kupita ndi kuchokera ku ziwalo, PET scan imapereka chidziwitso chambiri cha momwe ziwalo ndi ziwalo zimagwirira ntchito.

Kujambula kwa mtima kwa PET kumatha kudziwa ngati magawo am'mimba mwanu akulandila magazi okwanira, ngati pali kuwonongeka kwa mtima kapena zilonda zam'mimba mumtima, kapena ngati pali zinthu zambiri zosalongosoka mu mnofu wamtima.

Kujambula kwa PET kumafunikira zochepa zamagetsi (tracer).

• Izi zimaperekedwa kudzera mumitsempha (IV), nthawi zambiri mkati mwa chigongono.
• Imadutsa m'magazi anu ndikusonkhanitsa m'ziwalo ndi minofu, kuphatikiza mtima wanu.
• Tracer imathandizira radiologist kuwona madera kapena matenda ena momveka bwino.

Muyenera kudikirira pafupi ndi momwe tracer imakhudzidwira ndi thupi lanu. Izi zimatenga pafupifupi ola limodzi nthawi zambiri.

Kenako, mudzagona pa tebulo laling'ono, lomwe limalowa mu sikani yayikulu yofanana ndi ngalande.

• Maelekitirodi a electrocardiogram (ECG) adzaikidwa pachifuwa panu. Chojambulira cha PET chimazindikira zikwangwani kuchokera pa chosaka.
• Kompyutala imasintha zotsatira kukhala zithunzi za 3-D.
• Zithunzizo zimawonetsedwa pa polojekiti kuti radiologist iwerenge.

Muyenera kunama pomwe mukuyesa PET kuti makina athe kupanga zithunzi zomveka za mtima wanu.

Nthawi zina, kuyezetsa kumachitika limodzi ndi kuyesa kupsinjika (zolimbitsa thupi kapena kupsinjika kwa pharmacologic).

Kuyesaku kumatenga pafupifupi mphindi 90.

Mutha kupemphedwa kuti musadye chilichonse kwa maola 4 kapena 6 musanajambulitse. Mutha kumwa madzi. Nthawi zina mungapatsidwe chakudya chapadera musanayezedwe.

Uzani wothandizira zaumoyo wanu ngati:

• Mukuopa malo oyandikira (khalani ndi claustrophobia). Mutha kupatsidwa mankhwala okuthandizani kuti mukhale ogona komanso osakhala ndi nkhawa.
• Muli ndi pakati kapena mukuganiza kuti mutha kukhala ndi pakati.
• Muli ndi chifuwa chilichonse chojambulidwa ndi utoto (chosiyanitsa).
• Mumatenga insulin ya matenda ashuga. Muyenera kukonzekera mwapadera.

Nthawi zonse muuzeni omwe akukuthandizani zamankhwala omwe mukumwa, kuphatikiza omwe amagulidwa popanda mankhwala. Nthawi zina, mankhwala amatha kusokoneza zotsatira za mayeso.

Mungamve kuluma kwakuthwa pamene singano yomwe ili ndi chonyamulira iikidwa mumtambo wanu.

Kujambula kwa PET sikumapweteka. Gome likhoza kukhala lolimba kapena lozizira, koma mutha kupempha bulangeti kapena pilo.

Intakomu m'chipindamo imakupatsani mwayi wolankhula ndi munthu nthawi iliyonse.

Palibe nthawi yochira, pokhapokha mutapatsidwa mankhwala oti musangalale.

Kusanthula mtima kwa PET kumatha kuwulula kukula, mawonekedwe, kapangidwe kake, ndi magwiridwe antchito amtima.

Amagwiritsidwa ntchito nthawi zambiri mayeso ena, monga echocardiogram (ECG) ndi mayesero a mtima samapereka chidziwitso chokwanira.

Kuyesaku kungagwiritsidwe ntchito kuzindikira mavuto amtima ndikuwonetsa madera omwe magazi amayenda bwino.

Zithunzi zingapo za PET zitha kutengedwa pakapita nthawi kuti mudziwe momwe mukuyankhira kuchipatala cha matenda amtima.

Ngati mayeso anu anali okhudzana ndi masewera olimbitsa thupi, mayesero abwinobwino amatanthauza kuti mumatha kuchita masewera olimbitsa thupi kwa nthawi yayitali kapena yayitali kuposa anthu azaka zanu komanso kugonana. Simunakhale ndi zisonyezo kapena kusintha kwa kuthamanga kwa magazi kapena ECG yanu yomwe idakudetsani nkhawa.

Palibe zovuta zomwe zimapezeka pakukula, mawonekedwe, kapena kagwiritsidwe ntchito ka mtima. Palibe madera omwe radiotracer yasonkhanitsa modabwitsa.

Zotsatira zachilendo zitha kukhala chifukwa cha:

• Mitsempha ya Coronary
• Kulephera kwa mtima kapena mtima

Kuchuluka kwa radiation yomwe imagwiritsidwa ntchito pakuwunika PET ndikotsika. Imafanana ndi ma radiation ofanana ndi ma CT scan ambiri. Komanso, cheza sichikhala motalika kwambiri mthupi lanu.

Amayi omwe ali ndi pakati kapena akuyamwitsa ayenera kuuza owapatsa chithandizo asanayesedwe. Makanda ndi makanda omwe akukula m'mimba amasamala kwambiri zotsatira za radiation chifukwa ziwalo zawo zikukulabe.

N'zotheka, ngakhale kuti nkokayikitsa kwambiri, kukhala ndi vuto linalake ku zinthu zowononga mphamvuzo. Anthu ena amamva kuwawa, kufiira, kapena kutupa pamalo obayira.

Ndizotheka kukhala ndi zotsatira zabodza pakuyesa kwa PET. Shuga wamagazi kapena milingo ya insulin imatha kukhudza zotsatira za mayeso kwa anthu omwe ali ndi matenda ashuga.

Makina ambiri a PET tsopano akuchitidwa limodzi ndi CT scan. Kuphatikiza uku kumatchedwa PET / CT.
