Uninzi lwee-MRI scanners ezisetyenziswa kwezonyango yi-1.5T okanye i-3T, apho u-'T' emele iyunithi yamandla emagnethi, eyaziwa ngokuba yiTesla. Ii-MRI scanners ezineTeslas eziphezulu zinemagnethi enamandla ngakumbi ngaphakathi kwebhore yomatshini. Nangona kunjalo, ngaba inkulu ihlala ingcono? Kwimeko yamandla emagnethi eMRI, akusoloko kunjalo.
I-MRI enamandla aphezulu emagnethi ayiqinisekisi ukuba kukho uhlolo olungcono kunye nokuxilongwa kweemeko zonyango. Enyanisweni, ukhetho olufanelekileyo lwe-MRI luxhomekeke kwizinto ezahlukeneyo kunye nezinto eziqwalaselwayo, ezifana namalungu athile athathwayo umfanekiso, ukhuseleko kunye nentuthuzelo yesigulana, kunye nomgangatho womfanekiso. Ngoko ke, kunini apho kufanelekile ukusebenzisa iskena se-1.5T okanye se-3T? Makhe sihlolisise eminye yemiba ephambili phakathi kwezi zimbini.
Ukhuseleko kunye nesantya somfanekiso
Ukulinganisela isantya sokuskena kunye nokugcina ubushushu bomzimba kuzisa umngeni kwi-MRI yomzimba wonke. Enye yeemveliso ze-MRI kukunyusa ubushushu bomzimba, njengoko izicubu zomzimba zifunxa amandla e-electromagnetic ngexesha lokuskena, okwaziwa ngokuba yi-Specific Absorption Rate (SAR). Xa kuskenwa ngomatshini we-1.5T, imida yokufudumeza ifikelelwa kwiindawo ezithile ngexesha lokuskena. Ukuba ukuskena okufanayo kwenziwe nge-3T scanner, ubushushu bomzimba buya kunyuka ngokuphindwe kane, budlule umda wobushushu ngokuphindwe kane. Kukho iindlela zokujongana nale ngxaki, ezinje ngokubeka isithuba phakathi kokuskena ukuze kwandiswe amaxesha okuskena okanye ukunciphisa isisombululo sokuskena. Ke ngoko, ukusebenzisa i-1.5T MRI kungcono kuba kunika amava akhululekileyo nakhuselekileyo kwisigulane ngaphandle kokubeka umgangatho womfanekiso esichengeni.
Ukuskena Izigulana Ngezifakelo
Eyona ngxaki inkulu kulo naluphi na uvavanyo lokufota linqanaba lokhuseleko, yiyo loo nto zonke iimvavanyo zokufota zinemigaqo engqongqo kangaka. Ngokuphathelele i-MRI, kwiimeko ezininzi, izigulana zinokuskenwa ngokukhuselekileyo kusetyenziswa oomatshini be-1.5T kunye ne-3T MRI.
Nangona kunjalo, amandla aphezulu emagnethi aza neengozi eziphezulu. Izigulana ezinee-implants zesinyithi kunye nezixhobo, kuquka ii-pacemakers, i-AIDS yokuva, kunye nazo zonke iintlobo ze-implants, zisengozini enkulu yokuchaphazeleka yi-magnetic fields kwi-3T scanners. Ke ngoko, ezi zigulana zingakhuseleka ngakumbi nge-1.5T MRI scanner.
Umgangatho womfanekiso
Ukuchaneka kwemifanekiso ye-MRI kubalulekile ekuxilongweni ngokuchanekileyo nasekuchongeni iingxaki emzimbeni. Ngokuqhelekileyo kucingelwa ukuba i-MRI enamandla amakhulu emagnethi iya kuvelisa imifanekiso ekumgangatho ophezulu. Nangona oku kuyinyani kwiimeko ezithile, umatshini we-1.5T MRI uluncedo kakhulu ekufota ngokubanzi, ngelixa umatshini we-3T MRI udla ngokusetyenziswa ukufota imifanekiso eneenkcukacha ezininzi zezakhiwo ezincinci ezifana nengqondo okanye isihlathi.
Umgangatho wemifanekiso ye-MRI ubalulekile ekuxilongweni ngokuchanekileyo nasekufumaneni izinto ezingaqhelekanga. Iskena se-3T MRI sifanelekile kakhulu ekufoteni iindawo ezincinci ezifana nobuchopho kunye namalungu amancinci. Nangona kunjalo, amandla aphezulu emagnethi angaba yikrele elibukhali kabini. Enye ingxaki kukuba umatshini we-3T MRI usengozini enkulu yokwenziwa kwemifanekiso. Ukunqongophala okuqhubekayo kwe-3T kumqolo nasemzimbeni kubandakanya ukuthambekela kwigesi emathunjini, enokuthi ifihle amalungu angqongileyo, kunye nefuthe le-dielectric, apho iindawo zomfanekiso zibonakala zimnyama ngenxa yobude be-radiofrequency obusetyenziswa kwi-3T imaging. Kukwakho nokwanda kwezinto ezibangelwa lulwelo. Zonke ezi ngxaki zinokuchaphazela umgangatho weskeni.
Ngelizwi elinye
Nangona kunokubonakala ngathi i-MRI scanner enamandla aphezulu yeyona ndlela ilungileyo, ayilobali liphela elo. Kwihlabathi eligqibeleleyo, iingcali ze-radiology zingathanda ukuba i-MRI ivelise imifanekiso ekumgangatho ophezulu kwizigulana zazo ngokukhawuleza nangokukhuselekileyo. Nangona kunjalo, inyani ibonisa ukuba awunakuba nayo ngaphandle kokubeka emngciphekweni. Ngoko ke, ngaba uza kufumana ii-scan ezikhawulezayo ngexabiso lomgangatho womfanekiso? Okanye ukhethe i-scan ekhuselekileyo, kodwa ubeke emngciphekweni wokubeka izigulana kumatshini ixesha elide? Impendulo echanekileyo ixhomekeke kakhulu ekusetyenzisweni kwe-MRI.
Esinye isihloko esifanele siqwalaselwe kukuba xa kuskenwa isigulane, kuyimfuneko ukufaka i-contrast agent emzimbeni wesigulane. Kwaye oku kufuneka kufezekiswe ngoncedo lwe-injector ye-contrast agent. I-LnkMedyinkampani eyenza imveliso ekhethekileyo ekuveliseni, ekuphuhliseni nasekuthengiseni iisirinji ze-contrast agent. IkwiShenzhen, eGuangdong, eTshayina. Inamava eminyaka emi-6 yophuhliso ukuza kuthi ga ngoku, kwaye inkokheli yeqela le-LnkMed R&D ine-Ph.D. kwaye inamava angaphezu kweminyaka elishumi kweli shishini. Iinkqubo zemveliso zenkampani yethu zonke zibhalwe nguye. Ukususela oko yasekwa, ii-contrast agent injectors zeLnkMed ziqukaI-CT single contrast media injector, I-CT head injector ezimbini, I-MRI contrast media injector, I-Angiography yoxinzelelo oluphezulu lwe-injector, (kunye nesirinji kunye neetyhubhu ezifanelekileyo kwiimpawu ezivelaMu-edrad,Guerbet,Nemoto, LF, Medtron, Nemoto, Bracco, SINO,Seacrown) zamkelwe kakuhle zizibhedlele, kwaye iiyunithi ezingaphezu kwama-300 zithengisiwe ekhaya nakwamanye amazwe. I-LnkMed isoloko igxininisa ekusebenziseni umgangatho olungileyo njengesixhobo sokuxoxisana kuphela ukuze abathengi bayithembe. Esi sesona sizathu sibalulekileyo sokuba iimveliso zethu zesirinji ye-contrast agent enoxinzelelo oluphezulu ziqatshelwe yimarike.
