Iningi lama-scan e-MRI asetshenziswa kwezokwelapha yi-1.5T noma i-3T, kanti u-'T' umele iyunithi yamandla ensimu yamagnetic, eyaziwa ngokuthi i-Tesla. Ama-scan e-MRI ane-Tesla ephakeme afaka i-magnet enamandla kakhulu ngaphakathi kwebhore lomshini. Kodwa-ke, ingabe amakhulu angcono njalo? Endabeni yamandla kazibuthe e-MRI, akunjalo ngaso sonke isikhathi.
I-MRI enamandla amakhulu kazibuthe ayiqinisekisi ngempela ukuhlolwa nokuxilongwa okungcono kakhulu kwezimo zezokwelapha. Eqinisweni, ukukhetha i-MRI efanele kuncike ezintweni ezahlukahlukene kanye nokucatshangelwa, njengezitho ezithile ezithathwayo, ukuphepha kwesiguli kanye nenduduzo, kanye nekhwalithi yesithombe. Ngakho-ke, kunini lapho kufaneleka khona ukusebenzisa isithwebuli se-1.5T noma se-3T? Ake sihlole eminye yemibono ebalulekile phakathi kwalokhu okubili.
Ukuphepha kanye nesivinini sesithombe
Ukulinganisela isivinini sokuskena nokugcina izinga lokushisa lomzimba kuletha inselele ku-MRI yomzimba wonke. Omunye wemikhiqizo engaphansi kwe-MRI ukwandisa izinga lokushisa lomzimba, njengoba izicubu zomzimba zimunca amandla kagesi ngesikhathi sokuskena, okwaziwa ngokuthi yi-Specific Absorption Rate (SAR). Uma kuskenwa ngomshini we-1.5T, imikhawulo yokushisa ifinyelelwa ezindaweni ezithile ngesikhathi sokuskena. Uma ukuskena okufanayo kwenziwe nge-3T scanner, izinga lokushisa lomzimba lingakhuphuka ngokuphindwe kane, lidlule umkhawulo wokushisa ngokuphindwe kane. Kunezindlela zokubhekana nale nkinga, njengokuhlukanisa ukuskena ukuze kwandiswe izikhathi zokuskena noma ukunciphisa ukuxazululwa kokuskena. Ngakho-ke, ukusebenzisa i-1.5T MRI kungcono njengoba kunikeza isipiliyoni esikhululekile nesiphephile sesiguli ngaphandle kokubeka engcupheni ikhwalithi yesithombe.
Ukuskena Iziguli Ngezitho Zokufakelwa
Okukhathaza kakhulu nganoma yikuphi ukuhlolwa kwezithombe yizinga lokuphepha, yingakho zonke izivivinyo zezithombe zineziqondiso eziqinile kangaka. Ngokuphathelene ne-MRI, ezimweni eziningi, iziguli zingaskenwa ngokuphephile kusetshenziswa imishini ye-1.5T kanye ne-3T MRI.
Kodwa-ke, amandla amakhulu e-magnetic field ahambisana nezingozi eziphezulu. Iziguli ezine-metal implants namadivayisi, okuhlanganisa ne-pacemakers, i-hearing AIDS, nazo zonke izinhlobo ze-implants, cishe zithinteka kakhulu yi-magnetic fields kuma-scanner e-3T. Ngakho-ke, lezi ziguli zingaba ziphephile nge-1.5T MRI scanner.
Ikhwalithi yezithombe
Ukunemba kwezithombe ze-MRI kubalulekile ekuxilongweni okunembile nasekuboneni ukukhubazeka emzimbeni. Ngokuvamile kucatshangwa ukuthi i-MRI enamandla amakhulu kazibuthe ingakhiqiza izithombe zekhwalithi ephezulu. Nakuba lokhu kuyiqiniso ezimweni ezithile, umshini we-1.5T MRI ungasetshenziswa ngezindlela eziningi ekuthathweni kwezithombe ezijwayelekile, kanti umshini we-3T MRI uvame ukusetshenziswa ukuthwebula izithombe ezinemininingwane eminingi yezakhiwo ezincane njengobuchopho noma isihlakala.
Ikhwalithi yezithombe ze-MRI ibalulekile ekuxilongweni okunembile nasekutholeni ukukhubazeka. Isikena se-3T MRI silungele kahle ukuthwebula izindawo ezincane njengobuchopho namalunga amancane. Kodwa-ke, amandla aphezulu kazibuthe angaba yinkemba esika nhlangothi zombili. Enye inkinga ukuthi umshini we-3T MRI usengozini enkulu yokuthwebula izithombe. Ukulinganiselwa okuqhubekayo kwe-3T emgogodleni nasemzimbeni kufaka phakathi ukuzwela okuvela kugesi emathunjini, okungafihla izitho ezizungezile, kanye nomphumela we-dielectric, lapho izindawo zesithombe zibonakala zimnyama ngenxa yobude be-radiofrequency obusetshenziswa ekuthwebuleni izithombe kwe-3T. Kukhona nokwanda kwezinto ezibangelwa uketshezi. Zonke lezi zinkinga zingathinta ikhwalithi yokuthwebula.
Ngezwi Elilodwa
Nakuba kungase kubonakale sengathi isithwebuli se-MRI esinamandla kakhulu siyindlela engcono kakhulu, akuyona yonke leyo ndaba. Ezweni eliphelele, odokotela be-radiology bangafuna ukuthi i-MRI ikhiqize izithombe ezisezingeni eliphezulu zeziguli zabo ngokushesha nangokuphephile. Kodwa-ke, iqiniso libonisa ukuthi awukwazi ukuba nesinye ngaphandle kokubeka engcupheni. Ngakho-ke, uzothola ukuskena okusheshayo ngezindleko zekhwalithi yesithombe? Noma ukhethe ukuskena okuphephile, kodwa usengozini yokudalula iziguli emshinini isikhathi eside? Impendulo efanele incike kakhulu ekusetshenzisweni okuyinhloko kwe-MRI.
Esinye isihloko esidinga ukunakwa ukuthi lapho kuskenwa isiguli, kuyadingeka ukufaka i-contrast agent emzimbeni wesiguli. Futhi lokhu kudinga ukufezwa ngosizo lwe-umjovo we-ejenti yokuqhathanisa. I-LnkMedingumkhiqizi ogxile ekukhiqizeni, ekuthuthukiseni nasekuthengiseni amasirinji e-contrast agent. Itholakala eShenzhen, eGuangdong, eShayina. Inesipiliyoni seminyaka engu-6 sokuthuthukisa kuze kube manje, futhi umholi wethimba le-LnkMed R&D uneziqu ze-Ph.D. futhi unolwazi lweminyaka engaphezu kweyishumi kulo mkhakha. Izinhlelo zemikhiqizo zenkampani yethu zonke zibhalwe nguye. Selokhu yasungulwa, ama-contrast agent injector e-LnkMed afaka phakathiI-CT single contrast media injector, Umjovo wekhanda eliphindwe kabili we-CT, Umjovo wemidiya yokungafani kwe-MRI, I-Angiography yokucindezela okuphezulu, (kanye nesipiringi namapayipi afanele izinhlobo ezivelaMu-edrad,Guerbet,Nemoto, LF, Medtron, Nemoto, Bracco, SINO,Seacrown) zamukelwa kahle yizibhedlela, futhi amayunithi angaphezu kuka-300 athengisiwe ekhaya nakwamanye amazwe. I-LnkMed ihlala iphikelela ekusebenziseni ikhwalithi enhle njenge-chip kuphela yokuxoxisana ukuze iwine ukwethenjwa kwamakhasimende. Lesi yisona sizathu esibaluleke kakhulu sokuthi imikhiqizo yethu yesirinji ye-contrast agent enomfutho ophezulu iqashelwa yimakethe.
Ukuze uthole ulwazi olwengeziwe mayelana ne-LnkMed'izijovo ze-s, xhumana nethimba lethu noma usithumelele i-imeyili ngaleli kheli le-imeyili:info@lnk-med.com
