Nānā PET: he aha ia, he aha ia a pehea e hana ai

• No ke aha ia
• Pehea e hana ai

ʻO ka scan PET, i kapa ʻia hoʻi ʻo tomitron emission compute tomography, kahi hōʻike kiʻi i hoʻohana ākea e ʻike pono i ka maʻi ʻaʻai, nānā i ka hoʻomohala ʻana o ka tumo a inā he metastasis. Hiki i ka PET scan ke hōʻike i ka hana o ke kino, ma o ka lawelawe ʻana i kahi mea radioactive, i kapa ʻia he tracer, a i ka wā e omo ʻia ai e ka meaola, hoʻopuka i ka radiation i hopu ʻia e nā lakohana a hoʻololi ʻia i kiʻi.

ʻAʻole hoʻonā ka hōʻike i ka ʻeha, akā hiki iā ia ke hōʻoluʻolu inā he claustrophobic ke kanaka, e like me ka mea i hana ʻia i kahi pono paʻa. Ma waho aʻe o ka noi ākea ʻana i ka oncology, pono pū ka PET scan i ke kuhi ʻia o nā maʻi neurological, e like me Alzheimer a me epilepsy.

ʻO ka PET scan kahi hōʻike e loaʻa ai i nā hoʻolālā olakino a me SUS e hana wale ʻia no ka hoʻokolokolo ʻana, ka hōʻoia ʻana a me ka nānā ʻana i ka maʻi ʻaʻai māmā, lymphomas, maʻi ʻaʻai kolona, ​​maʻi ʻaʻai kūpono a me nā maʻi immunoproliferative, e like me myeloma maha, kahi maʻi kahi e hoʻomaka ai nā hunaola koko. hoʻonui a hōʻiliʻili i ka iwi iwi. E ʻike he aha nā ʻōuli a pehea e ʻike ai i ka nui o ka myeloma.

No ke aha ia

ʻO ka PET scan kahi hōʻike diagnostic ʻokoʻa ʻokoʻa i nā hoʻokolohua kiʻi ʻē aʻe, e like me ka tomography i helu ʻia a me nā kiʻi resonance ʻumeʻume, e laʻa me. ʻO kēia no ka mea e ʻae i ka ʻike ʻana i nā pilikia ma ka pae o ke kelepona ma o ka hoʻokuʻu ʻia ʻana o ka radiation, ʻo ia, hiki iā ia ke nānā i ka hana metabolic o nā hunaola, e ʻike koke nei i ka maʻi ʻaʻai.

Ma waho aʻe o kāna noi i ka ʻike ʻana i ka maʻi ʻaʻai, hiki ke hoʻohana ʻia ka scan PET i:

• ʻIke i nā pilikia neurological, e like me ka epilepsy a me nā dementias;
• E hōʻoia no nā pilikia o ka puʻuwai;
• Nānā i ka ulu ʻana o ka maʻi ʻaʻai;
• Nānā i ka pane i ka therapy;
• E ʻike i nā kaʻina metastatic.

Hiki i ka PET scan ke hoʻoholo i ke kuhi a wehewehe i ka wānana, ʻo ia hoʻi, nā manawa o ka hoʻomaikaʻi a hōʻino paha o ka mea maʻi.

Pehea e hana ai

Hana ʻia ka hoʻāʻo me ka lawelawe waha, ma o nā wai, a i ʻole pololei i loko o ka aa o ka tracer, kahi glucose maʻamau i kahakaha ʻia me kahi mea radioactive. Ma muli o ka tracer he glucose, ʻaʻole kū kēia hōʻike i kahi pilikia olakino, no ka mea ua hoʻopau maʻalahi ʻia e ke kino. Pono e lawelawe i ka tracer me ka hoʻokē ʻai no 4 a 6 mau hola, e like me ka ʻōlelo aʻoaʻo olakino, a hoʻopau ʻia ka scan PET ma hope o 1 hola, e ʻae ai i ka manawa no ka mea radioactive e lawe ʻia e ke kino, a hala ma kahi o 1 hola.

Hana ʻo PET scan i ka heluhelu ʻana i ke kino, ka hopu ʻana i ka radiation i hoʻoili ʻia a hana i nā kiʻi. I ka hoʻokolokolo ʻana i nā hana tumo, ʻo kahi laʻana, ʻo ka ʻai ʻana o ka glucose e nā hunaola he nui loa, ʻoiai ʻo ka glucose ke kumu o ka ikehu e pono ai no ka hoʻokaʻawale ʻana o ka cell. No laila, e loaʻa i nā kiʻi i nā kiko kikoʻī kahi e ʻoi aku ai ka nui o ka hoʻohana ʻia ʻana o ka glucose a, a no laila, ʻoi aku ka nui o ka hoʻokuʻu ʻana o ka radiation, i hiki ke hoʻokina i ka tumo.

Ma hope o ka hoʻāʻo he mea nui ia e inu nui ka wai i ke kanaka i mea e hoʻopau maʻalahi ʻia ai ka tracer. Hoʻohui ʻia, aia paha he mau hōʻailona allergy mālie, e like me ka ʻulaʻula, kahi i pahu ʻia ai ka tracer.

ʻAʻohe cont contications ka hōʻike a hiki ke hoʻokō ʻia ma nā poʻe i loaʻa i ka maʻi diabetes a me nā puʻuwai. Eia nō naʻe, ʻaʻole aʻoaʻo ʻia nā wahine hāpai a hānai paha e hana i kēia hoʻokolohua diagnostic, ma ke ʻano he mea radioactive hiki ke hoʻopili i ka pēpē.
