Uninzi lwezikena ze-MRI ezisetyenziswa kwezamayeza ziyi-1.5T okanye i-3T, kunye ne-'T' emele iyunithi yamandla ombane, eyaziwa ngokuba yiTesla. Izikena ze-MRI ezineTeslas eziphezulu zibonisa umazibuthe onamandla ngakumbi ngaphakathi kombhobho womatshini. Nangona kunjalo, ingaba enkulu ihlala ingcono? Kwimeko ye-MRI yamandla kazibuthe, akusoloko kunjalo.
Amandla emagnethi aphezulu eMRI ayiqinisekisi olona vavanyo lubalaseleyo kunye noxilongo lweemeko zonyango. Ngapha koko, olona khetho lufanelekileyo lwe-MRI luxhomekeke kwizinto ezahlukeneyo kunye neengqwalaselo, njengamalungu athile afanekiselwayo, ukhuseleko lwesigulana kunye nentuthuzelo, kunye nomgangatho wokucinga. Ke, xa kufanelekile ukusebenzisa i-1.5T okanye i-3T scanner? Makhe sihlolisise ezinye zeeyantlukwano eziphambili phakathi kwezi zimbini.
Ukhuseleko kunye nesantya soMfanekiso
Ukulinganisa isantya sokuskena kunye nokugcina ubushushu bomzimba kunika umngeni kwi-MRI yomzimba ogcweleyo. Enye yeemveliso ze-MRI kukwandisa ubushushu bomzimba, njengoko izicubu zomzimba zifunxa amandla ombane wombane ngexesha lokuskena, elaziwa ngokuba yiSpecific Absorption Rate (SAR). Xa uhlola ngomatshini we-1.5T, imida yokufudumeza ifikeleleke kwiindawo ezithile ngexesha lokuskena. Ukuba izikena ezifanayo beziqhutywa ngeskena se-3T, ubushushu bomzimba buya kunyuka ngokuphindwe kane, bugqithe kumlinganiselo wobushushu ngokuphindwe kane. Kukho iindlela zokulungisa lo mba, njengokubeka izithuba zokuskena ukwandisa amaxesha okuskena okanye ukunciphisa isisombululo seskeni. Ngoko ke, ukusebenzisa i-MRI ye-1.5T ikhethwayo njengoko inikezela ngamava akhululekile kwaye akhuselekile kwisigulane ngaphandle kokunciphisa umgangatho womfanekiso.
Ukuskena izigulana ngezifakelo
Eyona nkxalabo inkulu kulo naluphi na uvavanyo lomfanekiso linqanaba lokhuseleko, yiyo loo nto zonke iimvavanyo zemifanekiso zinezikhokelo ezingqongqo. Ngokubhekiselele kwi-MRI, kwiimeko ezininzi, izigulane zinokuskenwa ngokukhuselekileyo zisebenzisa i-1.5T kunye ne-3T imishini ye-MRI.
Nangona kunjalo, amandla aphezulu emagnethi eza kunye nemingcipheko ephezulu. Izigulane ezinokufakelwa kwesinyithi kunye nezixhobo, kubandakanywa i-pacemakers, i-AIDS yokuva, kunye nazo zonke iintlobo zokufakelwa, zinokuthi zichatshazelwe yimagnethi kwiiskena ze-3T. Ke ngoko, ezi zigulana ziya kukhuseleka ngakumbi ngeskena se-MRI ye-1.5T.
Umgangatho womfanekiso
Ukuchaneka kwemifanekiso ye-MRI ibalulekile kuxilongo oluchanekileyo kunye nokuchonga izinto ezingaqhelekanga emzimbeni. Ngokuqhelekileyo kucingelwa ukuba i-MRI enamandla amakhulu kazibuthe iya kuvelisa imifanekiso ephezulu. Ngelixa oku kuyinyani kwiimeko ezithile, umatshini we-MRI we-1.5T unomsebenzi omninzi wokucinga ngokubanzi, ngelixa umatshini we-3T we-MRI uhlala uqeshwa ukuba ubambe imifanekiso ecacileyo yezakhiwo ezincinci ezifana nengqondo okanye isihlahla.
Umgangatho wemifanekiso ye-MRI ubalulekile kuxilongo oluchanekileyo kunye nokufumanisa izinto ezingaqhelekanga. Iskena se-MRI ye-3T ifaneleke kakuhle ukucinga iindawo ezincinci ezifana nengqondo kunye namalungu amancinci. Nangona kunjalo, amandla amagnetic aphezulu anokuba yikrele elibukhali kabini.Olunye uhlangothi olusezantsi kukuba umatshini we-MRI we-3T uchaphazeleka ngakumbi kwimifanekiso yobugcisa. Imingcele eqhubekayo ye-3T kumqolo kunye nomzimba ibandakanya ukuchaphazeleka kwi-gas kwi-bowel, ekwazi ukufihla izitho ezizungezile, kunye nefuthe le-dielectric, apho iindawo zomfanekiso zibonakala zimnyama ngenxa ye-radiofrequency wavelength esetyenziswa kwi-imaging ye-3T. Kukwakho ukwanda kwezinto ezenziweyo ezibangelwa lulwelo. Yonke le miba inokuchaphazela umgangatho wokuskena.
NgeLizwi
Ngelixa kunokubonakala ngathi iskena se-MRI esinamandla yeyona ndlela ilungileyo, ayilobali lonke elo. Ehlabathini eligqibeleleyo, ii-radiologists ziya kufuna i-MRI ukuba ivelise imifanekiso esemgangathweni yezigulane zabo ngokukhawuleza nangokukhuselekileyo. Nangona kunjalo, inyaniso ibonisa ukuba awukwazi ukuba nayo ngaphandle kokulalanisa. Ke, ngaba uza kufumana izikena ezikhawulezayo ngexabiso lomgangatho womfanekiso? Okanye ukhethe ukuskena okukhuselekileyo, kodwa usengozini yokubeka abaguli kumatshini ixesha elide? Impendulo echanekileyo ixhomekeke kakhulu kusetyenziso oluphambili lweMRI.
Esinye isihloko esifuna ukuhoywa kukuba xa uskena isigulana, kuyafuneka ukuba utofe iarhente yokuchasana emzimbeni wesigulana. Kwaye oku kufuneka kuphunyezwe ngoncedo lwe-aisitofu searhente yokuchasana. LnkMedngumvelisi ogxile ekwenzeni, ekuphuhliseni, nasekuthengiseni iisirinji zearhente yokuchasa. Ibekwe eShenzhen, eGuangdong, eTshayina. Ineminyaka emi-6 yamava ophuhliso ukuza kuthi ga ngoku, kwaye inkokeli yeqela le-LnkMed R&D inePh.D. kwaye uneminyaka engaphezu kweshumi yamava kolu shishino. Iinkqubo zemveliso yenkampani yethu zonke zibhalwe nguye. Ukusukela ekusekweni kwayo, ii-ejenti zokuchasana ze-LnkMed zibandakanyaI-CT yesitofu semidiya eyahlukileyo, CT isitofu sentloko ezimbini, I-MRI yokuchasa i-media injector, I-Angiography yoxinzelelo oluphezulu, (kwaye nesirinji kunye neetyhubhu ezilungele iimveliso ezivela kuyoMedrad,Guerbet,Nemoto, LF, Medtron, Nemoto, Bracco, SINO,Seacrown) zamkelwa kakuhle zizibhedlele, kwaye ngaphezulu kwe 300 iiyunithi ezithengisiweyo ekhaya naphesheya. I-LnkMed ihlala igxininisa ekusebenziseni umgangatho olungileyo njengeyona nto iphambili ye-bargaining chip ukuphumelela ukuthembela kubathengi. Esi sesona sizathu sibalulekileyo sokuba kutheni iimveliso zethu zesirinji ezinoxinzelelo oluphezulu zibonwa yimarike.
