Ubuchwepheshe obusha bomjovo we CT, I-MRIfuthiI-Angiographyamasistimu asiza ukunciphisa umthamo futhi aqophe ngokuzenzakalelayo umehluko osetshenziselwa irekhodi lesiguli.
Muva nje, izibhedlela eziningi zinciphisa ngempumelelo izindleko ngokusebenzisa izijovo zokuqhathanisa eziklanywe ngobuchwepheshe obuthuthukisiwe ekunciphiseni udoti ohlukile kanye nokuqoqwa kwedatha okuzenzakalelayo ngomthamo isiguli esiwutholayo.
Okokuqala, ake sithathe amaminithi ambalwa ukuze sifunde ngemidiya yokuqhathanisa.
Iyini imidiya yokuqhathanisa?
Imidiya yokuqhathanisa iyinto ejovwa emzimbeni ukuze kuthuthukiswe umehluko phakathi kwezicubu zomzimba ezithombeni. Indlela efanelekile yokuqhathanisa kufanele ifinyelele ukugxila okuphezulu kakhulu ezicutshini ngaphandle kokukhiqiza noma yimiphi imiphumela emibi.
Izinhlobo ze-Contrast Media
Iodine, iminerali ekhishwe ngokuyinhloko enhlabathini, edwaleni nasemithonjeni yamanzi, ivamise ukusetshenziswa emithonjeni yezindaba ehlukile kukho kokubili i-CT ne-X-ray imaging. Imidiya yokuqhathanisa efakwayo yiyona esetshenziswa kakhulu, kanti i-CT idinga amanani amakhulu kakhulu. Onke ama-ejenti wokuqhathanisa asetshenziswa njengamanje ekhompuyutha (CT) asekelwe eringini ye-benzene ene-triiodinated. Nakuba i-athomu ye-iodine ibophezelekile ekukhanyeni kwe-radiopacity yemidiya ehlukile, inkampani ye-organic carrier inesibopho kwezinye izici zayo, ezifana ne-osmolality, tonicity, hydrophilicity, kanye ne-viscosity. Umthwali wezinto eziphilayo unesibopho semiphumela eminingi emibi futhi uthole ukunakwa okuningi kubacwaningi. Ezinye iziguli zisabela enanini elincane lemidiya yokuqhathanisa, kodwa imiphumela eminingi emibi ilamula umthwalo omkhulu we-osmotic. Ngakho-ke, emashumini ambalwa eminyaka adlule abacwaningi bagxile ekuthuthukiseni imidiya ehlukile enciphisa umthwalo we-osmotic ngemva kokuphathwa kwe-ejenti yokuqhathanisa.
Yini ama-injection emidiya yokuqhathanisa?
Izijovo zokuqhathanisa ziyizisetshenziswa zezokwelapha ezisetshenziselwa ukujova imidiya ehlukile emzimbeni ukuze kuthuthukiswe ukubonakala kwezicubu zezinqubo zokuthwebula zezokwelapha.(Thatha i-CT double head high pressure injector njengesibonelo, bona isithombe esingezansi:)
Ukuthi ubuchwepheshe obusha kakhulu bunjaniumjovo wengcindezi ephezuluukusiza ukunciphisa imfucuza yemidiya yokuqhathanisa ngesikhathi sokujova?
1.Izinhlelo Zomjovo Ezizenzakalelayo
Amasistimu omjovo azenzakalelayo angalawula ngokunembile inani lokuqhathanisa elisetshenzisiwe, elinikeza amathuba amasha eminyango ye-radiology efuna ukwenza lula futhi ibhale phansi ukusetshenziswa kwayo kwemidiya yokuqhathanisa. Ngokuthuthuka kwezobuchwepheshe, iama-injection aphezuluziguqukile zisuka kuzijovo ezilula ezenziwa ngezandla zaya kumasistimu azenzakalelayo angagcini nje ngokulawula ngokunembile inani le-ejenti yemidiya yokuqhathanisa esetshenziswayo, kodwa futhi enze kube lula ukuqoqwa kwedatha okuzenzakalelayo kanye nemithamo yomuntu siqu yesiguli ngasinye.
I-LnkMedisungule ama-injection athile okuqhathanisa ezinqubo zokufakwa emthanjeni ku-Computed Tomography (CT) kanye ne-Magnetic Resonance Imaging (I-MRI) kanye nezinqubo ze-intrarterial ekungeneleleni kwenhliziyo kanye ne-peripheral. Zonke lezi zinhlobo ezine zama-injection zivumela umjovo ozenzakalelayo. Kukhona futhi eminye imisebenzi ezenzakalelayo eklanyelwe ukwenza lula ukuhamba komsebenzi kwabantu bokunakekelwa kwempilo kanye nokuthuthukisa ukuphepha, njengokugcwalisa okuzenzakalelayo kanye nokufakwa kuqala, i-othomathikhi yokufaka i-plunger nokuhoxisa lapho unamathisela futhi ukhipha imijovo. Ukunemba kwevolumu kungaba phansi ku-0.1mL, kunika amandla umthamo onembe kakhulu womjovo ophakathi nendawo.
2. Izijovo ezingenamjovo
Izijovo zamandla ezingenawo umjovo ziye zavela njengesixazululo sokunciphisa imfucuza yemidiya ehlukile. Lolu khetho lunikeza izikhungo ithuba lokusebenzisa imidiya yokuqhathanisa kahle ngangokunokwenzeka. NgoMashi 2014, iGuerbet yethula i-FlowSens, uhlelo lwayo lomjovo ongenalo isirinji olwakhiwe umjovo wesikhwama esithambile kanye nezinto ezilahlwayo ezihlobene, kusetshenziswa i-hydraulic, injector engenawo isirinji ukuletha imidiya ehlukile; "Smart" entsha kaBracco Enika amandla izijovo ezingenasiring ziyakwazi ukusebenzisa ithonsi ngalinye. kokuqhathanisa kulayishwe ohlelweni ukuze uthole umnotho omkhulu. Kuze kube manje, idizayini yazo ifakazele ukuthi izijovo zamandla ezingenayo isirinji bezisebenziseka kalula futhi zisebenza kahle kunomjovo wamandla wesirinji ekabili, enodoti omningi nge-CT ngayinye ethuthukisiwe ebonwa kokugcina. Umjovo ongenamjovo uphinde wavumela ukonga kwezindleko okungaba ngu-$8 ngesiguli ngasinye uma kubhekwa izindleko eziphansi nokusebenza okuthuthukisiwe kwamadivayisi.
Njengomphakeli,I-LnkMedyenza ukonga izindleko kumakhasimende ayo kube yinto ehamba phambili. Sizibophezele ekuklameni imikhiqizo esebenza kahle kakhulu, ephephile futhi eyonga kakhulu ngokusungula izinto ezintsha zobuchwepheshe ukuze songe izindleko zamakhasimende ethu.
