Hangarau werohanga hou mō CT, MRImeAngiographyKa āwhina ngā pūnaha ki te whakaiti i te horopeta, ā, ka tuhi aunoa i te rerekētanga i whakamahia mō te pūkete tūroro.
Nō nā tata nei, kua piki haere te maha o ngā hōhipera kua angitu ki te whakaheke i ngā utu mā te whakamahi i ngā werohanga rerekētanga i hangaia ki ngā hangarau matatau hei whakaiti i te para o ngā rerekētanga rerekētanga, me te kohikohi raraunga aunoa mō te horopeta e whiwhi ana te tūroro.
Tuatahi, me tango he meneti torutoru ki te ako mō ngā rauemi rerekē.
He aha te pāpāho rerekētanga?
Ko te rauemi whakaata he matū e werohia ana ki roto i te tinana hei whakarei ake i ngā rerekētanga i waenga i ngā kiko o te tinana i runga i ngā whakaahua. Ko te rauemi whakaata pai rawa atu me eke ki te kukū teitei rawa i roto i ngā kiko me te kore e puta he pānga kino.
Ngā Momo Pāpāho Whakarerekētanga
Ko te iodine, he kohuke i tangohia mai i te oneone, te toka me te tote, e whakamahia whānuitia ana i roto i ngā rauemi whakaata mō te whakaahua CT me te hihi-X. Ko ngā rauemi whakaata i whakatōngia ngā mea e whakamahia whānuitia ana, ā, ko te CT te mea e hiahiatia ana te nui rawa atu o ngā rahinga katoa. Ko ngā kaihoko whakaata rorohiko (CT) katoa e whakamahia ana i tēnei wā e ahu mai ana i te mowhiti benzene triiodinated. Ahakoa ko te ngota iodine te kawenga mō te radiopacity o ngā rauemi whakaata, ko te kaikawe rauropi te kawenga mō ōna āhuatanga kē atu, pērā i te osmolality, te tonicity, te hydrophilicity, me te viscosity. Ko te kaikawe rauropi te kawenga mō te nuinga o ngā pānga kino, ā, kua nui te aro o ngā kairangahau. Ko ētahi tūroro e tauhohe ana ki te iti o ngā rauemi whakaata, engari ko te nuinga o ngā pānga kino ka puta mai i te kawenga osmotic nui. Nō reira, i roto i ngā tekau tau kua pahure ake nei, kua arotahi ngā kairangahau ki te whakawhanake i ngā rauemi whakaata e whakaiti ana i te kawenga osmotic i muri i te whakahaerenga o te kaihoko whakaata.
He aha ngā werohanga pāpāho rerekē?
Ko ngā werohanga rerekētanga he taputapu hauora e whakamahia ana hei werohanga i ngā rauemi rerekētanga ki roto i te tinana hei whakarei ake i te tirohanga a ngā kiko mō ngā tikanga whakaahua hauora. (Tangohia te werohanga pēhanga teitei upoko rua CT hei tauira, tirohia te pikitia i raro nei:)
Me pēhea te hangarau hou i roto iwerohanga pēhanga teiteiāwhina ki te whakaiti i te moumou o ngā rauemi whakahāngai i te wā e werohia ana?
1. Ngā Pūnaha Werohanga Aunoa
Ka taea e ngā pūnaha werohanga aunoa te whakahaere tika i te nui o te rerekētanga e whakamahia ana, e tuku ana i ngā huarahi hou mō ngā tari irahiko e titiro ana ki te whakahaere me te tuhi i tā rātou whakamahinga o ngā pāpāho rerekētanga. Nā te whanaketanga hangarau, ko tengā werohanga pēhanga teiteikua whanake haere mai i ngā werohanga ā-ringa māmā noa ki ngā pūnaha aunoa e kore anake e whakahaere tika ana i te nui o te kaihoko rongoā rerekē e whakamahia ana, engari e āwhina ana hoki i te kohikohi raraunga aunoa me ngā horopeta whaiaro mō ia tūroro takitahi.
LnkMedkua whakawhanakehia he werohanga rerekē motuhake mō ngā tikanga ā-uaua i roto i te Tomography Rorohiko (CT) me te Whakaahua Āhua Aukume (MRI) me ngā tikanga ā-roto i roto i te wawaotanga ngākau me te taha. Ka taea e ēnei momo werohanga e whā te werohanga aunoa. He maha atu anō ngā mahi aunoa kua hangaia hei whakahaere i te rere mahi a te hunga hauora me te whakarei ake i te haumaru, pērā i te whakakī me te whakakī aunoa, te neke whakamua me te hoki aunoa o te pūwero ina tāpirihia, ina wetewetehia rānei ngā ngira. Ka taea te heke iho i te tika o te rōrahi ki te 0.1mL, ka taea ai te horopeta tika ake o te werohanga o te rauemi rerekē.
2. Ngā Werohanga Kore-Singering
Kua puta ake ngā werohanga hiko kore-wero hei otinga hei whakaiti i te para o ngā pāpāho rerekē. Mā tēnei kōwhiringa ka taea e ngā whare te whakamahi i ngā pāpāho rerekē kia tino whai hua. I te marama o Poutū-te-rangi 2014, i whakarewahia e Guerbet a FlowSens, tana pūnaha werohanga kore-wero he mea tito mai i tētahi werohanga putea ngohengohe me ngā mea whakakore e pā ana, e whakamahi ana i tētahi werohanga waipēhi, kore-wero hei tuku i ngā pāpāho rerekē; Ka taea e ngā werohanga kore-wero Empower "atamai" hou a Bracco te whakamahi i ia pata o te rerekētanga kua utaina ki roto i te pūnaha mō te penapena nui. Tae noa ki tēnei wā, kua whakamātauhia e tā rātou hoahoa he ngāwari ake te whakamahi me te whai hua o ngā werohanga hiko kore-wero i te werohanga hiko rua-wero, me te nui ake o te para mō ia CT whakarei-rerekētanga i kitea mō te mea whakamutunga. I taea hoki e te werohanga kore-wero te penapena utu tata ki te $8 mō ia tūroro ina whakaarohia te utu iti me te mahi pai ake o ngā taputapu.
Hei kaiwhakarato,LnkMede mea ana kia matua penapena utu mā āna kiritaki. Kua whakapau kaha mātou ki te hoahoa i ngā hua whai hua ake, haumaru ake, ā, he ohanga ake mā te auahatanga hangarau hei penapena utu mā ō mātou kiritaki.
