Izikena eziningi ze-MRI ezisetshenziswa kwezokwelapha ziyi-1.5T noma i-3T, ne-'T' emele iyunithi yamandla kazibuthe, eyaziwa ngokuthi i-Tesla. Izikena ze-MRI ezine-Tesla ephakeme zifaka uzibuthe onamandla kakhulu ngaphakathi kwebhore yomshini. Nokho, ingabe enkulu ihlala ingcono? Endabeni yamandla kazibuthe we-MRI, akunjalo ngaso sonke isikhathi.
I-MRI yamandla kazibuthe ephakeme ayiqinisekisi ukuhlolwa nokuxilongwa okungcono kakhulu kwezimo zezokwelapha. Eqinisweni, ukukhetha okuhle kwe-MRI kuncike ezicini nasekucatshangelweni okuhlukahlukene, njengezitho ezithile ezithwetshulwa, ukuphepha kwesiguli nokunethezeka, kanye nekhwalithi yokuthwebula. Ngakho-ke, kufaneleka nini ukusebenzisa isithwebuli esingu-1.5T noma se-3T? Ake sihlole umehluko oyinhloko phakathi kwakho kokubili.
Ukuphepha kanye nesivinini sesithombe
Ukulinganisa isivinini sokuskena nokugcina izinga lokushisa lomzimba linikeza inselele ku-MRI yomzimba ogcwele. Omunye wemikhiqizo ye-MRI ukwandisa izinga lokushisa lomzimba, njengoba izicubu zomzimba zimunca amandla kazibuthe kagesi ngesikhathi sokuskena, okwaziwa nge-Specific Absorption Rate (SAR). Lapho uskena ngomshini ongu-1.5T, imikhawulo yokushisisa ifinyelelwa ezindaweni ezithile ngesikhathi sokuskena. Uma izikena ezifanayo bezenziwa ngesikena se-3T, izinga lokushisa lomzimba belizokhuphuka ngokuphindwe kane, lidlule umkhawulo wokushisa ngokuphindwe kane. Kunezindlela zokubhekana nale nkinga, njengokuhlukanisa izikena ukuze kwandiswe izikhathi zokuskena noma ukunciphisa ukulungiswa kokuskena. Ngakho-ke, ukusebenzisa i-MRI ye-1.5T kuyathandeka njengoba inikeza isipiliyoni esikhululekile nesiphephile esigulini ngaphandle kokuyekethisa ikhwalithi yesithombe.
Ukuskena Iziguli Ngezimila
Okukhathaza kakhulu noma yikuphi ukuhlolwa kwesithombe izinga lokuphepha, yingakho zonke izivivinyo zezithombe zinemihlahlandlela eqinile. Ngokuqondene ne-MRI, ezimweni eziningi, iziguli zingaskenwa ngokuphepha kusetshenziswa imishini ye-MRI ye-1.5T ne-3T.
Nokho, amandla kazibuthe aphezulu eza nezingozi eziphakeme. Iziguli ezinokufakwa kwensimbi nemishini, okuhlanganisa izihlinzeki-nhliziyo, i-AIDS yokuzwa, nazo zonke izinhlobo zokufakelwa, kungenzeka ukuthi zithintwe amandla kazibuthe kuzikena ze-3T. Ngakho-ke, lezi ziguli zingaphepheka kangcono ngesithwebuli se-MRI esingu-1.5T.
Ikhwalithi yokuthwebula
Ukunemba kwezithombe ze-MRI kubalulekile ekuxilongeni okunembayo kanye nokuhlonza okungavamile emzimbeni. Ngokuvamile kucatshangwa ukuthi i-MRI enamandla kazibuthe amakhulu izokhiqiza izithombe zekhwalithi ephezulu. Nakuba lokhu kuyiqiniso ezimweni ezithile, umshini we-MRI we-1.5T usebenza ngezindlela ezihlukahlukene ekucabangeni okuvamile, kuyilapho umshini we-3T MRI uvame ukuqashwa ukuze uthwebule izithombe ezinemininingwane eminingi yezakhiwo ezincane njengobuchopho noma isihlakala.
Ikhwalithi yezithombe ze-MRI ibalulekile ekuxilongeni okunembile kanye nokuthola okungavamile. Iskena se-3T MRI sifaneleka kahle ekuthwebuleni izindawo ezincane njengobuchopho namalunga amancane. Kodwa-ke, amandla kazibuthe aphakeme angaba inkemba esika nhlangothi zombili.Okunye phansi ukuthi umshini we-3T MRI ungenwa kalula yizinto zobuciko bezithombe. Imikhawulo eqhubekayo ye-3T emgogodleni nasemzimbeni ihlanganisa ukuthambekela okuvela kugesi emathunjini, okungafihla izitho ezizungezile, kanye nomthelela we-dielectric, lapho izindawo zesithombe zibonakala zimnyama ngenxa ye-wavelength ye-radiofrequency esetshenziswe ku-3T imaging. Kukhona nokwanda kwezinto zokwenziwa ezibangelwa uketshezi. Zonke lezi zinkinga zingathinta ikhwalithi yokuskena.
NgeZwi
Nakuba kungase kubonakale sengathi isithwebuli se-MRI esinamandla kakhulu siyindlela engcono kakhulu, akuyona indaba yonke. Ezweni eliphelele, izazi ze-radiologists zingafuna i-MRI ukuthi ikhiqizele iziguli zabo izithombe ezisezingeni eliphezulu ngokushesha nangokuphepha. Nokho, iqiniso libonisa ukuthi ngeke ube nalo ngaphandle kokuyekethisa. Ngakho-ke, ingabe uzothola ukuskena okusheshayo ngenani lekhwalithi yesithombe? Noma ukhethe ukuskena okuphephile, kodwa usengozini yokubeka iziguli emshinini isikhathi eside? Impendulo efanele incike kakhulu ekusetshenzisweni okuyinhloko kwe-MRI.
Esinye isihloko esidinga ukunakwa ukuthi lapho uskena isiguli, kuyadingeka ukuthi ujove i-ejenti yokuqhathanisa emzimbeni wesiguli. Futhi lokhu kudinga ukufezwa ngosizo lwe-aumjovo we-ejenti yokuqhathanisa. I-LnkMedingumkhiqizi ogxile ekukhiqizeni, ekuthuthukiseni, nasekudayiseni amasirinji e-ejenti ehlukile. Itholakala eShenzhen, Guangdong, China. Ineminyaka engu-6 yesipiliyoni sokuthuthuka kuze kube manje, futhi umholi weqembu le-LnkMed R&D unePh.D. futhi unesipiliyoni seminyaka engaphezu kweshumi kulo mkhakha. Izinhlelo zemikhiqizo yenkampani yethu zonke zibhalwe nguye. Selokhu yasungulwa, izijovo ze-ejenti ehlukile ze-LnkMed zihlanganisaIsijojo semidiya esihlukile esisodwa se-CT, I-CT dual head injector, Umjovo wemidiya wokuqhathanisa we-MRI, I-Angiography ephezulu yomfutho wegazi injector, (kanye nesirinji namashubhu afanele amabhrendi asukaMedrad,Guerbet,Nemoto, LF, Medtron, Nemoto, Bracco, SINO,Seacrown) zamukelwe kahle izibhedlela, kanti amayunithi angaphezu kuka-300 asedayisiwe ekhaya naphesheya. I-LnkMed ihlale iphikelela ekusebenziseni ikhwalithi enhle njengokuphela kwe-chip yezingxoxo zokuzuza ukwethenjwa kwamakhasimende. Lesi yisona sizathu esibaluleke kakhulu esenza ukuthi imikhiqizo yethu yesirinji yokuqhathanisa nengcindezi ephezulu ibonwe yimakethe.
Ukuze uthole olunye ulwazi mayelana ne-LnkMed'ama-injection, xhumana nethimba lethu noma usithumele i-imeyili ngaleli kheli le-imeyili:info@lnk-med.com
