Cov Tsiaj ib feem ntawm qhov kev ntsuas pom no tso siab rau kev sib sau ntawm cov xov tooj cua muaj suab thaj sib xws, FDG . Hauv cov qog nqaij hlav cancer, muaj kev tsim cov piam thaj ntau dhau thiab yog li ntawd, nce ntxiv FDG nqus. Cov qog ua qog kuj tau nce tus nqi metabolic thiab, vim li ntawd, yog FDG xav.
Tsis tas li, puas mob tshwm rau ntawm PET scan?
Nws yog ib qho tseem ceeb kom nco ntsoov tias a PET scan tsis muaj peev xwm sib txawv ntawm kev ua vim qog thiab ua haujlwm vim tsis yog cov txheej txheem qog noj ntshav, xws li mob lossis kis mob. Lub tshuab ua ke cov duab los ntawm Tsiaj thiab CT ua ke los txiav txim siab ua haujlwm ( Tsiaj ) thiab cov ntaub ntawv txheej txheem (CT).
Kuj Paub, dab tsi FDG kev nqus tau qhia? Kev sib raug zoo ntawm FDG kev txais tos nyob rau hauv Tsiaj kev tshuaj xyuas thiab kev coj noj coj ua hauv kev mob qog noj ntshav hauv lub mis. BACKGROUND: Positron emission tomography ( Tsiaj ) yog ib qho qauv siv tsis tau siv rau hauv kev kuaj mob thiab theem ntawm mob qog noj ntshav lub mis. Txawm li cas los xij, ntau yam tuaj yeem cuam tshuam rau fluoro-deoxyglucose ( FDG ) nqus los ntawm cov qog.
Kuj paub yog, vim li cas thiaj siv FDG hauv PET scans?
Piv txwv li, hauv PET scans ntawm lub hlwb, lub tshuab hluav taws xob atom tau siv rau cov piam thaj (ntshav qab zib) los tsim cov radionuclide hu ua cov tshuaj fluorodeoxyglucose ( FDG ), vim tias lub hlwb siv cov piam thaj rau nws cov metabolism. FDG yog dav siv hauv PET scanning.
Dab tsi tuaj yeem muab qhov tsis raug zoo ntawm PET scan?
Cov qog nqaij hlav zoo uas ua rau mob hnyav FDG ntau ntxiv Tsiaj /Kev kuaj CT tau piav qhia, thiab cov no yuav tsum raug lees paub ntawm qhov muaj peev xwm ua rau a cuav tsis zoo kev kuaj mob. Cov qog no suav nrog: fibrous mesothelioma, schwannoma, txhoj puab heev neurofibromas thiab enchondromas (Shreve li al, 1999).

Tsis zoo li MRIs, PET scans siv positron. Ib tus neeg taug qab tau txhaj tshuaj rau hauv koj lub cev uas tso cai rau tus kws kho hluav taws xob pom thaj chaw uas tau tshuaj xyuas. Ib qho MRI scan tuaj yeem siv thaum koj lub cev hloov lossis cov hlab ntshav raug nug, qhov PET scan yuav siv los pom koj lub cev ua haujlwm

Tus tsiaj ntawv sawv cev rau tomitron emission tomography. Tus tsiaj ntawv PET siv tshuaj maj mam siv tshuaj maj mam nthuav tawm thaj tsam ntawm koj lub cev uas cov cell ua haujlwm ntau dua li ib txwm muaj. Nws tau siv los pab txheeb xyuas qee yam mob xws li mob qog noj ntshav. Nws kuj tseem tuaj yeem pab nrhiav seb qhov twg thiab seb mob qog noj ntshav tau kis mus li cas
