MIBG scintiscan

MIBG scintiscan yog ib hom kev ntsuam xyuas kev ntsuas. Nws siv cov tshuaj kua hluav taws xob (hu ua tracer). Lub scanner pom los yog lees paub qhov muaj pheochromocytoma thiab neuroblastoma. Cov no yog hom qog uas cuam tshuam cov hlab ntaws.

Ib qho xov tooj cua (MIBG, iodine-131-meta-iodobenzylguanidine, lossis iodine-123-meta-iodobenzylguanidine) raug txhaj rau txoj leeg ntshav. Cov compound no txuas rau cov qog ua haujlwm tshwj xeeb.

Koj yuav muaj cov scan ntawd tom qab hnub ntawd lossis hnub tom qab. Rau feem ntawm txoj kev ntsuas no, koj dag saum ib lub rooj hauv qab caj npab ntawm lub scanner. Koj lub plab yog luam theej. Koj yuav tau rov qab kuaj dua rau 1 mus rau 3 hnub. Txhua tus scan yuav siv 1 txog 2 teev.

Ua ntej lossis thaum qhov ntsuas, koj tuaj yeem muab tshuaj sib tov rau iodine. Qhov no txwv tsis pub koj cov qog ua pa mus ntawm lub radioisotope ntau dhau.

Koj yuav tsum kos npe rau daim foos tso cai. Yuav kom koj hnav lub tsho tshaj sab hauv tsev kho mob lossis khaub ncaws xoob haum zoo. Koj yuav tsum tau tshem tawm cov hniav nyiaj hniav kub lossis cov khoom siv hlau ua ntej txhua tus ntxaij. Ntau yam tshuaj cuam tshuam nrog kev sim.

Kev ntsuam xyuas no yog ua los pab ntsuas pheochromocytoma. Nws tau ua thaum ntsuas CT ntawm lub plab lossis kuaj hauv plab MRI tsis muab cov lus teb meej. Nws kuj tseem siv los pab txhawm rau tshuaj neuroblastoma thiab tuaj yeem siv rau cov qog nqaij hlav carcinoid.

Tsis muaj dab tsi tshwm sim ntawm lub qog.

Cov txiaj ntsig tsis zoo yuav qhia tau tias:

• Pheochromocytoma
• Ntau tus kab mob endocrine neoplasia (MEN) II
• Carcinoid qog
• Neuroblastoma

Muaj qee qhov hluav taws xob tshwm sim los ntawm radioisotope. Cov hluav taws xob tawg ntawm cov xov tooj cua no yog siab dua li ntawm lwm qhov. Koj yuav tau ceev faj ntxiv rau ob peb hnub tom qab ntsuas. Koj tus kws khomob yuav qhia rau koj tias yuav ua li cas.

Qhov kev ntsuas no yuav tsum TSIS ua rau cov poj niam cev xeeb tub. Qhov hluav taws xob tuaj yeem ua rau muaj kev phom sij rau tus menyuam hauv plab.
