Fofo Fa'afoma'i Fa'aaniukilia
O le a le ata fa'afoma'i?
O ata fa'afoma'i faaniukilia (e ta'ua fo'i o le radionuclide scanning) ose meafaigaluega fa'apitoa e su'esu'e ai aua e le gata ina fa'aalia ai le anatomy (fa'atulagaga) o se okeni po'o se vaega o le tino, ae fa'apea fo'i le galuega a le okeni.O lenei fa'aopoopoga "fa'amatalaga fa'atino" e mafai ai e vaila'au faaniukilia ona su'esu'eina fa'ama'i ma tulaga fa'afoma'i eseese i se taimi vave atu nai lo isi su'ega fa'afoma'i fa'afoma'i e maua ai fa'amatalaga fa'aanatomi (fa'atulagaina) e uiga i se okeni po'o se vaega o le tino.O vailaʻau faaniukilia e mafai ona taua i le vave suʻesuʻeina, togafitiga, ma le puipuia o le tele o tulaga faʻafomaʻi ma faʻaauau pea ona tupu aʻe o se meafaigaluega faʻafomaʻi malosi.
MO LE TELE FA'AVAE FA'AMALELEI o lo'o tu'uina atu fa'ata'ita'iga fa'ata'ita'iga fa'afoma'i ua avea ma vaega o latou olaga i aso ta'itasi mo fa'ata'ita'iga fa'a-leitio lautele (ie, CT, MR, X-ray, PET, SPECT, etc.).Ae ui i lea, o polofesa i nei faʻalapotopotoga, mai fomaʻi, tekinolosi, ma pule, i le aufaigaluega PACS / IT, ua latou lagona foi le tiga o le leai o ni fofo PACS talafeagai mo le tele o auala eseese.O faʻataʻitaʻiga sili ona le faʻaaogaina e le PACS o faʻataʻitaʻiga faʻataʻitaʻiga faʻanatura, e aofia ai le PET-CT, SPECT-CT, fatu faʻamalositino, ma vailaʻau faaniukilia lautele.
E ui lava e laʻititi le faʻataʻitaʻiga mole mole faaniukilia pe a mafaufau i le aofaʻi o suʻega e faia i le tausaga, o lona taua e le tatau ona faʻatauvaʻa, i le falemaʻi ma le tupe.Ua fa'amaonia le PET-CT o le fa'ata'ita'iga fa'apitoa pe a o'o mai ile su'esu'ega ole kanesa.O le fatu faaniukilia o le auala lea e filifili ai mo fatu e le fa'asalaina.Ole vaila'au faaniukilia lautele e maua ai le tele o fa'ata'ita'iga fa'atino e leai se isi auala e mafai ona fa'atusalia.I mea tau tupe, PET-CT ma le fatu faaniukilia o loʻo i ai pea i totonu o faiga sili ona toe totogiina i faʻataʻitaʻiga faʻataʻitaʻiga.
O le a le mea e ese ai le faʻataʻitaʻiga faʻafomaʻi faʻafomaʻi faʻafomaʻi mai faʻataʻitaʻiga masani o le radiology o le ata muamua o galuega a le tino, ae o ata mulimuli o loʻo faʻatusalia le tino o le tino.O le mafuaʻaga lea e taʻua ai faʻataʻitaʻiga mole faaniukilia i nisi taimi o le metabolic imaging.Ina ia mafai ona suʻesuʻeina galuega a le tino mai ata na maua, e manaʻomia le vaʻai faʻapitoa ma auʻiliʻili meafaigaluega.O nei mea faigaluega o mea tonu ia o loʻo misi mai le tele o le PACS i aso nei.
I lenei tulaga, E tele ma sili atu kamupani faʻatekonolosi faʻafomaʻi faʻafomaʻi e manaʻo e atiaʻe le PET, SPECT.
