Nhanganyaya yeCT, Enhanced Computed Tomography (CECT) uye PET-CT

Nekuvandudzika kweruzivo rwehutano hwevanhu uye kushandiswa kwakapararira kweCT ine dose shoma mukuongororwa kwemuviri, maronda emumapapu akawanda anowanikwa panguva yekuongororwa kwemuviri. Zvisinei, musiyano ndewekuti kune vamwe vanhu, vanachiremba vachiri kukurudzira varwere kuti vaite bvunzo yeCT inovandudza. Kwete izvozvo chete, PET-CT yave kupinda zvishoma nezvishoma mumunda wekuona kwemunhu wese mukurapa. Musiyano uripi pakati pavo? Ungasarudza sei?

Zvinonzi CT yakawedzerwa ndeyekubaya mushonga une iodine une contrast agent kubva mutsinga uchienda mutsinga yeropa wobva waita CT scan. Izvi zvinogona kuona maronda asingawanikwe muCT scans dzakajairika. Zvinogonawo kuona ropa riripo uye kuwedzera huwandu hwekuongorora chirwere uye sarudzo dzekurapa.

Saka rudzii rwemaronda anoda kuwedzerwa kweCT? Kutaura zvazviri, kuwedzerwa kweCT scan kunobatsira zvikuru kune maronda akasimba anopfuura 10 mm kana kuti makuru hilar kana mediastinal masses.

Saka chii chinonzi PET-CT? Zvichitaurwa zviri nyore, PET-CT musanganiswa wePET neCT. CT ndiyo tekinoroji yekombiyuta yetomography. Kuongorora uku kwava kuzivikanwa nemhuri dzese. Munhu paanongorara pasi, muchina unoiongorora, uye vanogona kuziva kuti mwoyo, chiropa, chirebvu, mapapu neitsvo zvakaita sei.

Zita resainzi rePET rinonzi positron emission tomography. Munhu wese asati aita PET-CT, anofanira kubaya jekiseni remhando ye18F-FDGA, rine zita rakazara rekuti "chlorodeoxyglucose". Kusiyana neglucose yakajairika, kunyange zvazvo ichigona kupinda mumasero kuburikidza nemidziyo inotakura glucose, inochengetwa mumasero nekuti haigone kutora chikamu muzviitiko zvinotevera.

Chinangwa chePET scan ndechekuongorora kugona kwemasero akasiyana kushandisa glucose, nekuti glucose ndiyo sosi inonyanya kukosha yesimba remetabolism yemunhu. Kana glucose ikadyiwa zvakanyanya, kugona kwayo metabolic kunowedzera simba. Chimwe chezvinhu zvakakosha zvemamota ane kenza ndechekuti metabolic level yakakwira zvakanyanya kupfuura yenyama dzakajairwa. Zvichitaurwa zviri nyore, mamota ane kenza "anodya glucose yakawanda" uye anowanikwa nyore nyore nePET-CT. Saka, zvinokurudzirwa kuita PET-CT yemuviri wese nekuti inodhura zvishoma. Basa guru rePET-CT nderekuona kana bundu racho rapararira, uye kunzwa kwaro kunogona kusvika 90% kana kupfuura.

Kune varwere vane mapundu emapapu, kana chiremba akaona kuti mapundu acho ane kenza yakanyanya, zvinokurudzirwa kuti murwere aongororwe nePET-CT. Kana bundu racho raonekwa kuti rapararira, rinoenderana zvakananga nekurapwa kwemurwere, saka kukosha kwePET-CT hakugone kupfuudzwa zvakanyanya. Uye ifananidzo. Ichi ndicho chimwe chezvikonzero zvikuru zvePET-CT. Kune rumwe rudzi rwemurwere runodawo PET-CT: kana zvakaoma kutonga mapundu asina njodzi uye ane kenza kana mapundu anogara munzvimbo, PET-CT inzira yakakosha yekuongorora. Nekuti mapundu "anodya shuga yakawanda."

Zvose pamwe chete, PET-CT inogona kuona kana paine bundu uye kana bundu racho rakapararira mumuviri wese, nepo CT yakawedzerwa ichishandiswa mukuongorora nekurapa bundu guru remapapu uye bundu repakati pemapapu. Asi zvisinei nerudzi rwekuongorora, chinangwa ndechekubatsira vanachiremba kuita sarudzo dziri nani kuitira kuti vape zvirongwa zviri nani zvekurapa varwere.

Sezvatinoziva tese, kukura kweindasitiri yemifananidzo yezvokurapa hakuparadzaniswi nekugadzirwa kwemidziyo yekurapa yakatevedzana - majekiseni ekudzivirira emhando dzakasiyana-siyana uye zvinodyiwa zvinotsigira - zvinoshandiswa zvakanyanya mundima iyi. MuChina, iyo inozivikanwa neindasitiri yayo yekugadzira, kune vagadziri vazhinji vanozivikanwa mudzimba nekune dzimwe nyika nekugadzira michina yemifananidzo yekurapa, kusanganisiraLnkMedKubva payakavambwa, LnkMed yanga ichinyanya kutarisana nekushandisa majekiseni ekudzivirira kupisa kwemhepo ane simba guru.
