Kutheni le nto iyimfuneko ukusebenzisa i-injector yoxinzelelo oluphezulu ukutofa iMedia yokuchasana ngexesha loviwo oluphuculweyo lwe-CT?

Ngethuba lokuhlolwa kwe-CT ephuculweyo, umqhubi ngokuqhelekileyo usebenzisa i-injector yoxinzelelo oluphezulu ukuba afake ngokukhawuleza i-agent echaseneyo kwimithanjeni yegazi, ukwenzela ukuba izitho, izilonda kunye nemithambo yegazi ekufuneka ijongwe ingabonakaliswa ngokucacileyo. I-injector yoxinzelelo oluphezulu inokukhawuleza kunye nokuchaneka inani elaneleyo le-high-concentration-concentration media media kwi-blood body body, ukuthintela ukuchasana kweendaba ukuba kuhlanjululwe ngokukhawuleza emva kokungeniswa emzimbeni womntu. Isantya siqhele ukusetwa ngokwendawo yoviwo. Ngokomzekelo, ukuhlolwa kwesibindi esiphuculweyo, isantya se-injection sigcinwa kuluhlu lwe-3.0 - 3.5 ml / s. Nangona isitofu soxinzelelo oluphezulu sitofa ngokukhawuleza, okoko nje imithambo yegazi yesifundo ino-elasticity entle, umlinganiselo wokutofa jikelele ukhuselekile. Idosi ye-agent ye-agent esetyenziswe kwi-CT scan eyomeleziweyo imalunga newaka levolumu yegazi lomntu, elingayi kubangela ukuguquguquka okukhulu kumthamo wegazi lomxholo.

Xa ijelo leendaba elichasayo litofwe kumthambo womntu, umxholo uya kuziva umkhuhlane wendawo okanye wenkqubo. Oku kungenxa yokuba i-agent echaseneyo yikhemikhali eneempawu eziphezulu ze-osmotic. Xa i-injector yoxinzelelo oluphezulu ifakwe kwi-vein ngesantya esiphezulu, udonga lwegazi luya kuvuselelwa kwaye isifundo siya kuziva intlungu ye-vascular. Inokuthi isebenze ngokuthe ngqo kwi-vascular smooth muscle, ebangela ukuhlanjululwa kwemithambo yegazi yendawo kunye nokuvelisa ubushushu kunye nokungahambi kakuhle. Le yimpendulo ethambileyo yearhente engayi kubangela ingozi kumzimba womntu. Iza kubuyela kwimeko yesiqhelo ngokukhawuleza emva kophuculo. Ngoko ke, akukho mfuneko yokoyika okanye ukungaqondi ukuba umkhuhlane wengingqi okanye wenkqubo yenzeke xa i-agent echaseneyo itofwa.

I-LnkMed igxile kwishishini le-angiography kwaye ngumenzi oyingcali obonelela ngezisombululo zemifanekiso. YethuCT eyodwa,CT intloko ezimbini , I-MRI, kwayeDSAii-injection zoxinzelelo oluphezulu zisetyenziswa kakhulu kwizibhedlele ezinkulu ekhaya nakwamanye amazwe.
Sijonge ukwenza iimveliso zethu ukuba zisebenze ngakumbi ukukhawulelana nemfuno ejolise kwisigulana sakho kwaye zamkelwe ziiarhente zezonyango kwihlabathi liphela.
