Itekhnoloji entsha yesitofu ye CT, I-MRIkwayeI-AngiographyIinkqubo zinceda ukunciphisa umthamo kwaye zirekhode ngokuzenzekelayo umahluko osetyenziselwa irekhodi yesigulane.
Kutshanje, izibhedlele ezininzi zicuthe ngempumelelo iindleko ngokusebenzisa ii-injection zokuthelekisa eziyilwe ngobuchwephesha obuphucukileyo ekunciphiseni inkunkuma eyahlukileyo kunye nokuqokelelwa kwedatha okuzenzekelayo kwidosi isigulana esiyifumanayo.
Okokuqala, masithathe imizuzu emininzi ukufunda malunga nemidiya yokuchasana.
Yintoni imidiya yokuchasana?
Imidiya yothelekiso yinto etofelwe emzimbeni ukukhulisa umahluko phakathi kwezicubu zomzimba kwimifanekiso. Umlinganiselo ofanelekileyo wokuchasana kufuneka ufezekise ugxininiso oluphezulu kakhulu kwizicubu ngaphandle kokuvelisa nayiphi na imiphumo emibi.
Iindidi zeMedia yokuThetha
Iodine, iminerali ekhutshwe kuqala emhlabeni, etyeni nakwibrine, iqhele ukusetyenziswa kumajelo osasazo ohlukileyo kuzo zombini i-CT kunye ne-X-reyi imaging. Imidiya yokuchasana efakwayo zezona arhente zixhaphakileyo, kwaye iCT ifuna ezona xabiso likhulu. Zonke ii-agent zokuthelekisa ezisetyenziswayo ngoku zisekelwe kwiringi ye-benzene ene-triiodinated. Ngelixa iathom ye-iodine inoxanduva lokusasazeka kwemithombo yeendaba echaseneyo, umthwali wezinto eziphilayo unoxanduva kwezinye iipropathi zayo, ezinje nge-osmolality, tonicity, hydrophilicity, kunye ne-viscosity. I-organic carrier inoxanduva lobuninzi bemiphumo emibi kwaye ifumene ingqalelo eninzi kubaphandi. Ezinye izigulana zisabela kwiimali ezincinci zemithombo yeendaba echaseneyo, kodwa uninzi lweziphumo ezibi zilawulwa ngumthwalo omkhulu we-osmotic. Ke, kumashumi ambalwa eminyaka adlulileyo abaphandi bagxile ekuphuhliseni imidiya eyahlukileyo enciphisa umthwalo weosmotic emva kolawulo lwearhente yokuthelekisa.
Yintoni ii-injection zemidiya ezichasayo?
Ii-injection zothelekiso zizixhobo zonyango ezisetyenziselwa ukutofa imidiya echaseneyo emzimbeni ukuze kuphuculwe ukubonakala kwezicubu kwiinkqubo zokucinga zonyango.
Indlela iteknoloji entsha kwiisitofu soxinzelelo oluphezuluukunceda ukunciphisa inkcitho yemidiya eyahlukileyo ngexesha lokutofa?
1.IiNdlela zokuSebenza eziziSebenzisayo zokuTofa
Iinkqubo zesitofu ezizenzekelayo zinokulawula ngokuchanekileyo ubungakanani bokuthelekisa obusetyenziswayo, obubonelela ngamathuba amatsha kumasebe erediyoloji ajonge ukulungelelanisa kunye nokubhala usetyenziso lwawo lwemithombo yeendaba. Ngenkqubela phambili yetekhnoloji, iii-injection zoxinzelelo oluphezuluziye zavela kwii-injection ezilula zezandla ukuya kwiinkqubo ezizenzekelayo ezingalawuli ngokuchanekileyo kuphela inani le-arhente yemidiya eyahlukileyo esetyenzisiweyo, kodwa iququzelele ukuqokelelwa kwedatha ezenzekelayo kunye needosi zomntu ngamnye kwisigulane ngasinye.
LnkMediphuhlise ii-injection ezithile zokuchasana kwiinkqubo zomthambo kwiComputed Tomography (CT) kunye neMagnetic Resonance imaging (I-MRI) kunye neenkqubo ze-intrarterial kwi-cardiac kunye ne-peripheral intervention. Zonke ezi ntlobo zine zezitofu zivumela isitofu esizenzekelayo. Kukwakho neminye imisebenzi ezenzekelayo eyilelwe ukwenza lula ukuhamba komsebenzi wabantu bokhathalelo lwempilo kunye nokuphucula ukhuseleko, njengokuzaliswa ngokuzenzekelayo kunye nokuqala, i-automatic plunger advance kunye nokuhlehlisa xa uncamathisela kwaye ukhupha iisirinji. Ukuchaneka kwevolumu kunokuhla ukuya kwi-0.1mL, yenza ukuba idosi echanekileyo ngakumbi yenaliti ephakathi.
2. Izitofu ezingenazisirinji
Izitofu zamandla ezingenazisirinji ziye zavela njengesisombululo sokunciphisa inkcitho yemidiya eyahlukileyo. Olu khetho lunika izibonelelo ithuba lokusebenzisa imidiya yokuchasana kakuhle kangangoko. NgoMatshi ka-2014, iGuerbet yaphehlelela i-FlowSens, inkqubo yayo yokutofa engenasisirinji eyenziwe sisitofu sebhegi ethambileyo kunye nezinto ezilahlwayo ezinxulumeneyo, kusetyenziswa ihydraulic, isitofu esingenasisirinji ukuhambisa imidiya eyahlukileyo; Umahluko ulayishwe kwinkqubo yoqoqosho oluphezulu. Ukuza kuthi ga ngoku, uyilo lwazo lubonakalise ukuba izitofu zamandla ezingenazisirinji bezisebenziseka lula kwaye zisebenza kakuhle kunesitofu samandla esilinji ezimbini, kunye nenkunkuma eyongeziweyo ngokweCT eyomeleziweyo ejongwe yamva. I-injector ye-syringeless iphinde yavumela ukugcinwa kweendleko malunga ne-$ 8 ngesigulane xa kuqwalaselwa ixabiso eliphantsi kunye nokusebenza okuphuculweyo kwezixhobo.
Njengomthengisi,LnkMedyenza ukonga iindleko kubathengi bayo eyona nto iphambili. Sizibophelele ekuyileni iimveliso ezisebenza kakuhle, ezikhuselekileyo nezinoqoqosho ngakumbi ngokusungula izinto ezintsha zobuchwepheshe ukonga iindleko kubathengi bethu.
