PET kusanthula khansa ya m'mawere

Kujambula kwa positron emission tomography (PET) ndiyeso yojambula yomwe imagwiritsa ntchito mankhwala a radioactive (otchedwa tracer) kuti ayang'anire kufalikira kwa khansa ya m'mawere. Izi zimatha kuzindikira madera a khansa omwe MRI kapena CT scan singawonetse.

Kujambula kwa PET kumafunikira zochepa zamagetsi (tracer). Chopondachi chimaperekedwa kudzera mu mtsempha (IV), nthawi zambiri mkati mwa chigongono, kapena mumitsempha yaying'ono mdzanja lanu. Tracer amayenda m'magazi anu ndikusonkhanitsa m'ziwalo ndi zotupa ndikupereka chizindikiro chomwe chimathandizira akatswiriwa kuti awone madera kapena matenda ena momveka bwino.

Muyenera kudikirira pafupi pomwe thupi lanu limatenga cholowacho. Izi zimatenga pafupifupi ola limodzi.

Kenako, mudzagona pa tebulo laling'ono, lomwe limalowa mu sikani yayikulu yofanana ndi ngalande. Chojambulira cha PET chimazindikira zikwangwani zomwe zimaperekedwa kuchokera ku tracer. Kompyutayi imasintha zotsatira kukhala zithunzi za 3D. Zithunzizo zimawonetsedwa pompopompo kuti dokotala wanu amamasulire.

Muyenera kunama mukayesedwa. Kuyenda kwambiri kumatha kusokoneza zithunzi ndikupanga zolakwika.

Kuyesaku kumatenga pafupifupi mphindi 90.

Zithunzi zambiri za PET zimachitika limodzi ndi CT scan. Kuphatikiza uku kumatchedwa PET / CT.

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

Uzani wothandizira zaumoyo wanu ngati:

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

Nthawi zonse muuzeni omwe akukuthandizani za mankhwala 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. Chipinda ndi tebulo kumatha kukhala kozizira, koma mutha kupempha bulangeti kapena pilo.

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

Palibe nthawi yochira, pokhapokha mutapatsidwa mankhwala oti musangalale.

PET scan imagwiritsidwa ntchito nthawi zambiri mayeso ena, monga MRI scan kapena CT scan, OSAPEREKA zambiri zokwanira kapena madokotala akufuna kufalikira kwa khansa ya m'mawere ku ma lymph node kapena kupitirira apo.

Ngati muli ndi khansa ya m'mawere, dokotala wanu atha kuyitanitsa izi:

• Mukangopeza matenda anu kuti muwone ngati khansara yafalikira
• Mukalandira chithandizo ngati pali nkhawa kuti khansayo yabwerera
• Mukamalandira chithandizo kuti muwone ngati khansa ikulabadira chithandizo

PET scan sichigwiritsidwa ntchito poyesa, kapena kuzindikira, khansa ya m'mawere.

Zotsatira zabwinobwino zimatanthawuza kuti palibe malo kunja kwa bere momwe radiotracer yasonkhanitsidwa modabwitsa. Zotsatira izi zikutanthauza kuti khansa ya m'mawere sinafalikire mbali zina za thupi.

Madera ang'onoang'ono kwambiri a khansa ya m'mawere sangakhale pa PET scan.

Zotsatira zosazolowereka zitha kutanthauza kuti khansa ya m'mawere ikhoza kufalikira kunja kwa bere.

Shuga wamagazi kapena mulingo wa insulini zimatha kukhudza zotsatira za mayeso kwa anthu omwe ali ndi matenda ashuga.

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.

Azimayi omwe ali ndi pakati kapena akuyamwitsa ayenera kuuza adokotala asanakayezetse. 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.

Kusanthula kukachitika, mutha kupemphedwa kumwa madzi ambiri ndikukhala kutali ndi ana osakwana zaka 13 kapena aliyense woyembekezera kwa maola 24.

Ngati mukuyamwitsa, uzani dokotala wanu. Dokotala wanu angakulimbikitseni kuti musamamwe mkaka kwa maola 24 mutatha kuwerengera.
