Spatial daws teeb meem Qhov kev daws teeb meem ntawm CTyog qhov zoo tshaj qhov kev daws teeb meem ntawm magnetic resonance imaging (MRI), uas feem ntau yog 1-2 hli rau feem ntau cov kab ke thiab ntau tshaj qhov tsim nyog rau feem ntau. Kev siv tshuaj kho mob ntawm CT.
MRI puas muaj kev daws teeb meem siab?
Nws muaj peev xwm ua tiav peb-dimensional (3-D) muaj peev xwm, zoo heev cov ntaub so ntswg sib piv thiab siab spatial daws teeb meem. Tsis tas li ntawd, MRI tso cai rau kev ua haujlwm, diffusion thiab perfusion imaging.
Tus qauv twg muaj qhov kev daws teeb meem qis tshaj plaws?
Spatial daws teeb meem ntawm Ultrasound thiab Sib Nqus Resonance yog qhov nyuaj dua vim lub physics ntawm cov qauv duab no. Ntawm tag nrho cov qauv saum toj no Nuclear Tshuaj muaj qhov kev daws teeb meem qis tshaj plaws nrog PET / CT muaj qhov daws teeb meem ntawm 2 hli.
Thaum twg CT zoo dua MRI?
Ob qho MRIs thiab CT scans tuaj yeem saib cov qauv hauv lub cev. Txawm li cas los xij, CT scan nrawm duathiab tuaj yeem muab cov duab ntawm cov nqaij mos, lub cev nqaij daim tawv, thiab cov pob txha pob txha. MRI yog qhov ua tau zoo ntawm kev ntes cov duab uas pab kws kho mob txiav txim siab seb puas muaj cov ntaub so ntswg txawv txav hauv lub cev. MRIs tau nthuav dav ntxiv hauv lawv cov duab.
Qhov kev ua duab zoo tshaj plaws yog dab tsi?
Rau cov ntawv thov no, tshwj xeeb tshaj yog rau thaj chaw loj ntawm kev pom, volumetric MRI lossis CT yog qhov tsim nyog tshaj plaws imaging modality.
