Zomwe Zachitika Posachedwapa Majekeseni Apamwamba Amathandizira Kuchepetsa Zinyalala Zosiyanitsa

Ukadaulo watsopano wa jekeseni wa CT, MRIndiAngiographymachitidwe kumathandiza kuchepetsa mlingo ndi basi mbiri kusiyana ntchito kwa mbiri wodwala.

Posachedwapa, zipatala zochulukirachulukira zidachepetsa bwino ndalama pogwiritsa ntchito majekeseni osiyanitsa omwe adapangidwa mwaukadaulo wapamwamba pochepetsa zinyalala zosiyanitsa komanso kusonkhanitsa deta pamlingo womwe wodwala amalandira.

Choyamba, tiyeni titenge mphindi zingapo kuti tiphunzire za kusiyanitsa media.

Kodi kusiyanitsa media ndi chiyani?

Contrast media ndi chinthu chomwe chimabayidwa m'thupi kuti chiwongolere kusiyana pakati pa minofu yathupi pazithunzi. Kusiyanitsa koyenera kuyenera kukhala kokwera kwambiri mu minofu popanda kubweretsa zovuta zilizonse.

Mitundu ya Contrast Media

Iodine, mchere wotengedwa m'dothi, mwala ndi brine, amagwiritsidwa ntchito kwambiri posiyanitsa zithunzi za CT ndi X-ray. Makanema osiyanitsa omwe amagwiritsidwa ntchito kwambiri ndi omwe amagwiritsidwa ntchito kwambiri, pomwe CT imafunikira kuchuluka kwakukulu konse. Zonse zomwe zimagwiritsidwa ntchito pakali pano za computed tomography (CT) zimatengera mphete ya benzene ya triiodinated. Pomwe atomu ya ayodini imayang'anira ma radiopacity a media media, chonyamulira cha organic chimayang'anira zinthu zake zina, monga osmolality, tonicity, hydrophilicity, ndi viscosity. Wonyamula organic ndiye amachititsa zovuta zambiri ndipo walandira chidwi chochuluka kuchokera kwa ofufuza. Odwala ena amakhudzidwa ndi zochepa zowonetsera zowonetsera, koma zotsatira zake zambiri zimagwirizanitsidwa ndi kulemera kwakukulu kwa osmotic. Chifukwa chake, pazaka makumi angapo zapitazi ofufuza akhala akuyang'ana kwambiri pakupanga makanema osiyanitsa omwe amachepetsa kuchuluka kwa osmotic pambuyo poyang'anira othandizira.

Kodi majekeseni osiyanitsa media ndi chiyani?

Majekeseni osiyanitsa ndi zida zachipatala zomwe zimagwiritsidwa ntchito pobaya jekeseni wosiyanitsa m'thupi kuti ziwongolere mawonekedwe a minofu yamankhwala oyerekeza.

Momwe ukadaulo waposachedwa kwambirijekeseni wothamanga kwambirithandizani kuchepetsa kutaya kwa zinthu zosiyanitsa panthawi ya jekeseni?

1.Makina a Injector odzichitira okha

Makina ojambulira okha amatha kuwongolera kuchuluka kwa kusiyanitsa komwe kumagwiritsidwa ntchito, zomwe zimapereka mwayi kwa madipatimenti a radiology omwe akufuna kuwongolera ndikulemba momwe amagwiritsidwira ntchito ndi media. Ndi kupita patsogolo kwaukadaulo, majekeseni wothamanga kwambirizachokera ku majekeseni osavuta amanja kupita ku makina opangira makina omwe samangoyang'anira kuchuluka kwa ma media media omwe amagwiritsidwa ntchito, komanso amathandizira kusonkhanitsa deta ndi milingo yamunthu payekha payekha kwa wodwala aliyense.

LnkMedwapanga majekeseni apadera opangira njira zopangira mtsempha mu Computed Tomography (CT) ndi Magnetic Resonance Imaging (MRI) komanso njira zopangira ma intrarterial mu mtima ndi zotumphukira. Mitundu yonseyi inayi ya jekeseni imalola jekeseni wodziwikiratu. Palinso ntchito zina zodziwikiratu zomwe zimapangidwa kuti zifewetse kayendedwe ka ntchito za anthu azaumoyo ndikulimbitsa chitetezo, monga kudzaza basi ndi priming, kutsogola kodziwikiratu ndikubweza polumikiza ndi kutulutsa ma syringe. Kulondola kwa voliyumu kumatha kutsika mpaka 0.1mL, kumathandizira kuti mulingo wolondola kwambiri wa jakisoni wapakatikati.

2. Majekeseni opanda syringe

Majekeseni opanda syringe opanda mphamvu atuluka ngati yankho lochepetsera zinyalala zama media. Izi zimapereka mwayi wogwiritsa ntchito media media moyenera momwe mungathere. Mu Marichi 2014, Guerbet idakhazikitsa FlowSens, jakisoni wopanda syringe wopanda jekeseni wopangidwa ndi jekeseni wachikwama chofewa komanso zotayira zomwe zimagwirizanitsidwa, pogwiritsa ntchito jakisoni wa hydraulic, wopanda syringe kuti apereke zinthu zosiyanitsa; zosiyanitsa zodzaza mu dongosolo kwa chuma pazipita. Pakadali pano, mapangidwe awo atsimikizira kuti ma jakisoni amagetsi opanda syringe anali osavuta kugwiritsa ntchito komanso aluso kuposa jakisoni wamagetsi a syringe yapawiri, zotayira zambiri pa CT yowoneka bwino yowonera. Jakisoni wopanda syringe adalolanso kupulumutsa ndalama pafupifupi $8 pa wodwala aliyense akaganizira za kutsika mtengo komanso kuwongolera magwiridwe antchito a zida.

Monga supplier,LnkMedzimapangitsa kupulumutsa mtengo kwa makasitomala ake kukhala chinthu chofunikira kwambiri. Tadzipereka kupanga zinthu zogwira mtima kwambiri, zotetezeka komanso zandalama zambiri kudzera muukadaulo waukadaulo kuti tisunge ndalama kwa makasitomala athu.
