Kujambula PET kwa ubongo

Kujambula kwa ubongo positron emission tomography (PET) ndiyeso yojambula yaubongo. Amagwiritsa ntchito mankhwala a radioactive otchedwa tracer kuyang'ana matenda kapena kuvulala muubongo.

Kujambula kwa PET kumawonetsa momwe ubongo ndi ziwalo zake zimagwirira ntchito. Mayeso ena ojambula, monga maginito opanga maginito (MRI) ndi ma computed tomography (CT) amangowonetsa mawonekedwe aubongo.

Kujambula kwa PET kumafunikira zochepa zamagetsi (tracer). Izi zimaperekedwa kudzera mumitsempha (IV), nthawi zambiri mkati mwa chigongono. Kapena, mumapuma zinthu zowulutsa ma radio ngati mpweya.

Wosunthayo amayenda m'magazi anu ndikusonkhanitsa m'ziwalo ndi minofu. Tracer imathandizira wothandizira zaumoyo wanu kuti awone madera kapena matenda ena momveka bwino.

Mumadikirira pafupi pomwe chombocho chimakodwa ndi thupi lanu. Izi zimatenga pafupifupi ola limodzi.

Kenako, mwagona patebulo lochepetsetsa, lomwe limalowa mu sikani yayikulu yooneka ngati ngalande. Chojambulira cha PET chimazindikira zikwangwani kuchokera pa chosaka. Kompyutala imasintha zotsatira kukhala zithunzi za 3-D. Zithunzizo zimawonetsedwa pa polojekiti kuti wothandizirayo awerenge.

Muyenera kugona pomwe mukuyesedwa kuti makina athe kupanga zithunzi zomveka bwino za ubongo wanu. Mutha kupemphedwa kuti muwerenge kapena kulemba mayina ngati kukumbukira kwanu kukuyesedwa.

Kuyesaku kumatenga pakati pa mphindi 30 ndi maola awiri.

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

Uzani wothandizira 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).
• Mwatenga insulin ya matenda ashuga. Muyenera kukonzekera mwapadera.

Nthawi zonse muuzeni omwe akukuthandizani zamankhwala omwe mukumwa, kuphatikiza omwe amagulidwa popanda mankhwala. Nthawi zina, mankhwala amasokoneza 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.

Pambuyo pa mayeso, imwani madzi ambiri kuti mutulutse chopukutira m'thupi lanu.

Kujambula kwa PET kumatha kuwonetsa kukula, mawonekedwe, ndi magwiridwe antchito aubongo, kuti adokotala athe kuwonetsetsa kuti ikugwira ntchito moyenera. Amagwiritsidwa ntchito nthawi zambiri mayeso ena, monga MRI scan kapena CT scan, osapereka chidziwitso chokwanira.

Mayesowa angagwiritsidwe ntchito:

• Dziwani za khansa
• Konzekerani opaleshoni ya khunyu
• Thandizani kupeza matenda amisala ngati mayeso ena ndi mayeso sizikupatsani chidziwitso chokwanira
• Fotokozani kusiyana pakati pa matenda a Parkinson ndi zovuta zina zoyenda

Zithunzi zingapo za PET zitha kutengedwa kuti mudziwe momwe mukuyankhira kuchipatala cha matenda a khansa kapena matenda ena.

Palibe zovuta zomwe zimapezeka pakukula, mawonekedwe, kapena magwiridwe antchito aubongo. Palibe malo omwe tracer adasonkhanitsa modabwitsa.

Zotsatira zachilendo zitha kukhala chifukwa cha:

• Matenda a Alzheimer kapena dementia
• Chotupa chaubongo kapena kufalikira kwa khansa kuchokera mthupi lina kupita kuubongo
• Khunyu, ndipo amatha kudziwa komwe khunyu limayambira muubongo wanu
• Matenda oyenda (monga matenda a Parkinson)

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

Kujambula kwa PET kumatha kuchitika limodzi ndi CT scan. Kuphatikiza uku kumatchedwa PET / CT.
