Kujambula PET

Kujambula kwa positron emission tomography ndi mtundu wamayeso ojambula. Imagwiritsa ntchito chinthu chowononga radio chomwe chimatchedwa tracer kuyang'ana matenda mthupi.

Chojambula cha positron emission tomography (PET) chikuwonetsa momwe ziwalo ndi ziwalo zimagwirira ntchito.

• Izi ndizosiyana ndimayeso a MRI ndi CT. Mayesowa akuwonetsa kapangidwe ka, ndi magazi kutuluka ndi kutuluka m'ziwalo.
• Makina omwe amaphatikiza zithunzi za PET ndi CT, zotchedwa PET / CT, amagwiritsidwa ntchito kwambiri.

Pulogalamu ya PET imagwiritsa ntchito kanyumba kakang'ono ka radioactive. Tracer imaperekedwa kudzera mumitsempha (IV). Singano nthawi zambiri imayikidwa mkati mwa chigongono chanu. Wosunthayo amayenda m'magazi anu ndikusonkhanitsa m'ziwalo ndi minofu. Izi zimathandizira kuti radiologist iwonenso madera ena momveka bwino.

Muyenera kudikirira pamene wopondaponda amatengeka ndi thupi lanu. Izi zimatenga pafupifupi ola limodzi.

Kenako, mudzagona pa tebulo laling'ono lomwe limalowa mu sikani yayikulu yooneka ngati ngalande. PET imazindikira zikwangwani kuchokera kwa woponda. Kompyuta imasintha zizindikirazo kukhala zithunzi za 3D. Zithunzizo zimawonetsedwa pompani kuti wothandizira zaumoyo wanu awerenge.

Muyenera kugona chikhalire pamene mukuyesedwa. Kuyenda kwambiri kumatha kusokoneza zithunzi ndikupanga zolakwika.

Kutenga mayeso kumatenga nthawi yayitali bwanji kutengera gawo liti la thupi lomwe limajambulidwa.

Mutha kupemphedwa kuti musadye chilichonse kwa maola 4 kapena 6 musanajambulitse. Mutha kumwa madzi koma osamwa zakumwa zina kuphatikiza khofi. Ngati muli ndi matenda ashuga, omwe akukuthandizani adzakuwuzani kuti musamamwe mankhwala ashuga musanayezedwe. Mankhwalawa asokoneza zotsatira zake.

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).

Nthawi zonse muuzeni omwe akukuthandizani za mankhwala omwe mukumwa. Adziwitseni omwe akukuthandizani za mankhwala omwe mwagula popanda mankhwala. Nthawi zina, mankhwala amatha kusokoneza zotsatira za mayeso.

Mungamve kuluma kwakuthwa pamene singano yokhala ndi choponderacho imayikidwa mumthambo 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.

Kugwiritsa ntchito kwambiri PET scan ndi khansa, zikachitika:

• Kuwona kufalikira kwa khansa. Izi zimathandiza kusankha njira yabwino kwambiri yothandizira.
• Kuti muwone momwe khansa yanu ikuyankhira, mwina mukamalandira chithandizo kapena mukamaliza mankhwala.

Mayesowa amathanso kugwiritsidwa ntchito:

• Onani momwe ubongo umagwirira ntchito
• Dziwani gwero la khunyu muubongo
• Onetsani madera omwe magazi amayenda bwino
• Dziwani ngati kuchuluka m'mapapu anu ndi khansa kapena yopanda vuto

Zotsatira zabwinobwino zikutanthauza kuti kunalibe zovuta zomwe zimawoneka kukula, mawonekedwe, kapena malo a chiwalo. Palibe malo omwe tracer adasonkhanitsa modabwitsa.

Zotsatira zachilendo zimadalira gawo la thupi lomwe likuwerengedwa. Zotsatira zachilendo zitha kukhala chifukwa cha:

• Khansa
• Matenda
• Vuto ndi ntchito ya ziwalo

Kuchuluka kwa radiation yomwe imagwiritsidwa ntchito pakuyesa PET ndikofanana ndi momwe imagwiritsidwira ntchito pama CT scan ambiri. Zithunzi izi zimagwiritsa ntchito zida zazifupi, chifukwa ma radiation achoka mthupi lanu pafupifupi maola 2 mpaka 10. Kukhala ndi ma x-ray ambiri, CT kapena PET kuwunika pakapita nthawi kumatha kuwonjezera chiopsezo cha khansa. Komabe, chiwopsezo chojambulidwa kamodzi ndichaching'ono. Inu ndi dokotala muyenera kuyeza izi kuti musapindule ndi kupeza matenda oyenera.

Uzani omwe akukuthandizani musanayesedwe ngati muli ndi pakati kapena mukuyamwitsa. Makanda ndi makanda omwe akukula m'mimba amasamala kwambiri ma radiation chifukwa ziwalo zawo zikukulabe.

Nthawi zambiri, anthu amatha kusokonezeka ndi zomwe amatsatira. 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. Izi zimathandiza kupeza komwe kuli chotupacho.
