Munguva pfupi yapfuura, Scientific Reports yakaburitsa chidzidzo chekuenzanisa chinotarisa mashandiro ekiriniki ekushandiswa kwakawanda (MI) vs kushandiswa kamwe chete (SI)Injektori yeMRI contrasts, zvichipa ruzivo rwakakosha rwenzvimbo dzemifananidzo pakusarudza masisitimu ekuisa jekiseni. Chidzidzo ichi chinosimbisa kuti majekiseni anoshandisa nzira dzakawanda anopa mabhenefiti makuru mukushanda zvakanaka, kushandiswa kwakasiyana, uye kudzora mari.
Kubudirira Kwakawedzerwa Kwekushanda
Chidzidzo ichi chakaitwa paRadboud University Medical Center muNetherlands uye chaisanganisira varwere vanopfuura mazana matatu vaiongororwa neMRI contrast-enhanced scans. Chakakamurwa kuita zvikamu zviviri: mazuva gumi ekutanga achishandisa multi-use MRI injectors (MI) uye mazuva gumi anotevera achishandisa single-use injectors (SI). Zvakawanikwa zvakaratidza kuti avhareji yenguva yekugadzirira MI systems yaive maminetsi maviri nemasekondi makumi maviri nemana, zvichienzaniswa nemaminitsi mana nemasekondi makumi mashanu nemashanu eSI systems, zvichiratidza kuwedzera kukuru mukushanda. Kushandiswa kwezuva nezuva kweMajekiseni eCTuyeMajekiseni eMRI, izvi zvinochengetedza nguva zvinobvumira nzvimbo dzemifananidzo kuti dzigadzirise varwere vakawanda uye dzigadzirise mashandiro ekiriniki.
Kuderedza Kurasika Kwekusiyana Kwezvinhu Uye Kuchengetedza Mari
Marara emhando ye "contrast agent" ndiwo anonyanya kukosha pakushandisa nzvimbo yekufungidzira. Muchidzidzo ichi, masisitimu eSI ane sirinji dze7.5ml aive ne13% yekurasa marara, nepo masisitimu eMI aishandisa mabhodhoro e7.5ml akaderedza marara kusvika pa5%. Nekushandisa mabhodhoro makuru e15ml kana 30ml e "contrast" uye kugadzirisa mashandiro e "injection" zvichienderana nehuwandu hwemurwere, marara akaderedzwa zvakanyanya. Munzvimbo dzinoshandiswa scanning yakawanda, masisitimu e "injection" akawanda anogona kuderedza zvakanyanya mari inoshandiswa, zvichipa mabhenefiti ehupfumi kuzvipatara.
Kugutsikana Kwemushandi Kwakawedzerwa
Ruzivo rwemushandisi chinhu chakakosha pakusarudza michina yekurapa. Ongororo yevashandi yakaratidza kuti masisitimu eMI akawana mapoinzi akawanda mukushanda zvakanaka kwenguva, nyore kushandisa, uye nyore kushandisa, neavhareji yekugutsikana kwe4.7 kubva pa5, zvichienzaniswa ne2.8 yemasisitimu eSI. Ruzivo rwakavandudzwa rwemushandisi harungowedzera kugutsikana kwebasa chete asiwo runoderedza njodzi yekukanganisa kwekushanda, zvichiita kuti zvive nechokwadi chekuti kushandiswa kwakachengeteka kweMajekiseni eCTuyeMajekiseni eMRI.
Mabhenefiti Ekugadzira Majekiseni Anoshandiswa Zvakawanda
Masisitimu eMI anoshandisa macartridge emishonga ezuva nezuva uye mabhodhoro econtrast anogona kushandiswazve, zvichingoda kutsiviwa kwemachubhu nezvimwe zvinoshandiswa zvinoraswa pamurwere wega wega. Sisitimu iyi inogona kubata mhando mbiri dzezvinhu zvinosiyanisa mavara panguva imwe chete, zvakaita segadolinium yakajairwa uye gadolinium chaiyo yechiropa, zvichienderana nezvinodiwa zvakasiyana zvekuskena. Dhizaini iyi inoderedza matanho ekushanda uku ichichengetedza dosi yakasarudzika yemurwere wega wega. Masisitimu ese eMI neSI ane chitupa cheCE, achitevedzera mitemo yekuchengetedza michina yekurapa yeEU kuti ave nechokwadi chekuchengetedzwa kwekiriniki uye hutsanana.
Kukosha kweKliniki neMaindasitiri
Ongororo iyi inoratidza kuti kushandisa majekiseni eCT anoshandiswa kakawanda uye majekiseni eMRI anobatsira zvikuru mukushanda zvakanaka, kuderedza mari, uye kugutsikana kwevashandi. Kune nzvimbo dzemifananidzo, izvi zvinoreva kuchengetedza mifananidzo yemhando yepamusoro inovandudza kusiyanisa munzvimbo dzine huwandu hwakawanda uku uchigadzirisa kugoverwa kwezvishandiso zvevashandi.
Uyezve, nekuwedzera kwemitengo yezvinhu zvinosiyanisa zvinhu uye kuwedzera kwekutarisa pakuchengetedza nharaunda, masisitimu ekushandisa zvinhu zvakawanda anopa mamwe mabhenefiti. Kuderedza marara hakungodzikisi mari chete asiwo kunotsigira tsika dzinochengetedza nharaunda munzvimbo dzemazuva ano dzehutano.
Zvikumbiro Zveramangwana
Sezvo matekinoroji eMRI neCT achiramba achikura mukuongorora kwekiriniki, masisitimu ejekiseni anoshanda uye akachengeteka achava michina yakakosha yenzvimbo dzemifananidzo. Chidzidzo ichi chinopa data rinotsigira kugona uye kukosha kwemajekiseni ekushandisa akawanda mukuita kwezuva nezuva, zvichipa gwara kuzvipatara mukusarudza kutenga uye kugadzirisa mashandiro ebasa. Majekiseni eCT anoshandiswa akawanda uye majekiseni eMRI anogona kunge ari magadzirirwo akajairwa mune ramangwana, zvichivandudza mhando yese yebasa rekutora mifananidzo.
