Sei Zvichikosha Kushandisa Injector Yekudzvanya Nesimba Rakanyanya Kupinza Contrast Media Panguva Yekuongororwa KweCT Kwakawedzerwa?

Munguva yekuongororwa kweCT kwakawedzerwa, mushandi anowanzo shandisa injector ine pressure yakakwira kuti aise contrast agent nekukurumidza mutsinga dzeropa, kuitira kuti nhengo, maronda netsinga dzeropa dzinofanira kuonekwa zvionekwe zvakajeka. Injector ine pressure yakakwira inogona nekukurumidza uye nemazvo kuisa contrast media yakakwana mutsinga dzeropa dzemuviri wemunhu, ichidzivirira contrast media kuti isadzike nekukurumidza mushure mekuiswa mumuviri wemunhu. Kumhanya kunowanzo gadziriswa zvichienderana nenzvimbo yekuongororwa. Semuenzaniso, pakuongororwa kwechiropa kwakawedzerwa, kumhanya kwejekiseni kunochengetwa pakati pe3.0 - 3.5 ml/s. Kunyangwe injector ine pressure yakakwira ichibaya nekukurumidza, chero bedzi tsinga dzeropa dzemunhu dzine elasticity yakanaka, mwero wejekiseni wakachengeteka. Chiyero che contrast agent chinoshandiswa mu enhanced CT scan chingangoita chiuru chimwe chezviuru zvehuwandu hweropa remunhu, izvo zvisingazokonzere kuchinja kukuru muhuwandu hweropa remunhu.

Kana chinhu chinosiyanisa ropa chikapinzwa mutsinga yemunhu, munhu wacho anonzwa fivha yemunzvimbo kana kuti yemuviri. Izvi zvinodaro nekuti chinhu chinosiyanisa ropa ikemikari ine hunhu hwe osmotic hwakawanda. Kana chinhu chinopinza ropa chikapinzwa mutsinga nekukurumidza, madziro etsinga yeropa anomutswa uye munhu wacho anonzwa kurwadziwa kwetsinga dzeropa. Chinogonawo kushanda zvakananga patsandanyama dzakatsetseka dzetsinga dzeropa, zvichikonzera kukura kwetsinga dzeropa dzemunzvimbo uye zvichikonzera kupisa nekusagadzikana. Uku kutaura zvazviri, chiito chechinhu chinosiyanisa ropa chisingazokuvadzi muviri wemunhu. Chinodzokera kune zvakajairika nekukurumidza mushure mekugadziriswa. Saka, hapana chikonzero chekutya kana kusanzwisisa kana fivha yemunzvimbo kana yemuviri ikaitika kana chinhu chinoenzanisa ropa chikapinzwa.

LnkMed inotarisa paindasitiri ye angiography uye inyanzvi yekugadzira inopa mhinduro dzemifananidzo.CT imwe chete,CT musoro miviri , MRIuyeDSAMajekiseni ekudzivirira chirwere ane pressure yakanyanya anoshandiswa zvakanyanya muzvipatara zvikuru zvemuno nekunze kwenyika.
Chinangwa chedu ndechekuita kuti zvigadzirwa zvedu zvinyatsoshanda kuti zvigutse zvinodiwa nemurwere wenyu uye kuti zvizivikanwe nemasangano ekurapa pasi rese.
