1.5T vs 3T MRI - itandukaniro irihe?

Scaneri nyinshi za MRI zikoreshwa mubuvuzi ni 1.5T cyangwa 3T, hamwe na 'T' igereranya igice cyingufu za magnetique, kizwi nka Tesla. Scaneri ya MRI hamwe na Teslas yo hejuru irerekana rukuruzi ikomeye mumashini ya mashini. Ariko, binini buri gihe ni byiza? Kubireba imbaraga za magnetique ya MRI, ntabwo burigihe.

Imbaraga zikomeye za magneti MRI ntabwo byanze bikunze byemeza neza gusuzuma no gusuzuma indwara. Mubyukuri, guhitamo neza kwa MRI guterwa nibintu bitandukanye no gutekereza, nkingingo zihariye zishushanywa, umutekano wumurwayi no guhumurizwa, hamwe nubwiza bwibishusho. None, ni ryari bikwiye gukoresha 1.5T cyangwa 3T scaneri? Reka dusuzume bimwe mubyingenzi bitandukanye hagati yibi byombi.

Umutekano n'umuvuduko

Kuringaniza scan umuvuduko no gukomeza ubushyuhe bwumubiri bitanga ingorane mumubiri wuzuye MRI. Kimwe mu bicuruzwa biva muri MRI ni ukongera ubushyuhe bw'umubiri, kubera ko ingirangingo z'umubiri zikurura ingufu za electromagnetique mu gihe cya scan, izwi ku izina rya Absorption Rate (SAR). Iyo gusikana hamwe na mashini 1.5T, imipaka yo gushyushya igerwaho ahantu runaka mugihe cyo gusikana. Niba scan imwe yarakozwe hamwe na 3T scaneri, ubushyuhe bwumubiri bwazamuka inshuro enye, burenze ubushyuhe bwikubye kane. Hariho uburyo bwo gukemura iki kibazo, nko gutandukanya scan kugirango wongere ibihe byo gusikana cyangwa kugabanya gukemura kwa scan. Kubwibyo, gukoresha 1.5T MRI nibyiza kuko bitanga uburambe bwiza kandi bwumutekano kumurwayi bitabangamiye ubwiza bwibishusho.

Gusikana abarwayi hamwe nabatewe

Ikibazo gihangayikishije ikizamini icyo ari cyo cyose cyerekana amashusho ni urwego rwumutekano, niyo mpamvu ibizamini byose byerekana amashusho bifite amabwiriza akomeye. Ku bijyanye na MRI, akenshi, abarwayi barashobora gusuzumwa neza bakoresheje imashini 1.5T na 3T MRI.

Nyamara, imbaraga za magneti zo murwego rwo hejuru zizana ingaruka nyinshi. Abarwayi bafite ibyuma nibikoresho, harimo pacemakers, kumva sida, nubwoko bwose bwatewe, birashoboka cyane ko byibasirwa nimirima ya magneti muri scaneri ya 3T. Kubwibyo, aba barwayi baba bafite umutekano hamwe na 1.5T scaneri ya MRI.

Ubwiza bw'amashusho

Ubusobanuro bwamashusho ya MRI nibyingenzi mugupima neza no kumenya ibintu bidasanzwe mumubiri. Bikunze gufatwa ko MRI ifite imbaraga za magneti nyinshi yatanga amashusho meza. Mugihe ibi bifite ukuri mubihe bimwe na bimwe, imashini ya 1.5T MRI irahuza amashusho rusange, mugihe imashini ya 3T MRI ikoreshwa mugufata amashusho arambuye yuburyo buto nk'ubwonko cyangwa intoki.

Ubwiza bwamashusho ya MRI nibyingenzi mugupima neza no kumenya ibintu bidasanzwe. Scaneri ya 3T MRI ikwiranye no kwerekana uduce duto nkubwonko hamwe nuduce duto. Nyamara, imbaraga za magneti zisumba izindi zishobora kuba inkota y'amaharakubiri. Kimwe mubibi nuko imashini ya 3T MRI ishobora kwibasirwa nibishusho byerekana amashusho. Imbogamizi zikomeje kuba 3T mu ruti rw'umugongo no mu mubiri zirimo kwanduzwa na gaze mu mara, zishobora guhisha ingingo zikikije, ndetse n'ingaruka za dielectric, aho uduce tw’ishusho tugaragara nk'umwijima bitewe n'uburebure bwa radiofrequency ikoreshwa mu mashusho ya 3T. Hariho kandi kwiyongera mubihangano biterwa n'amazi. Ibi bibazo byose birashobora kugira ingaruka kumiterere ya scan.

Mu Ijambo

Mugihe bisa nkibisanzwe-MRI scaneri niyo nzira nziza, ntabwo arinkuru yose. Mw'isi itunganye, abahanga mu bya radiologue bifuza ko MRI itanga amashusho meza cyane kubarwayi babo vuba kandi neza. Ariko, ukuri kwerekana ko udashobora kugira umwe utabangamiye. Noneho, ugiye kubona scan byihuse ukoresheje ubwiza bwibishusho? Cyangwa hitamo scan itekanye, ariko ibyago byo guhura nabarwayi kumashini igihe kirekire? Igisubizo cyukuri giterwa ahanini nikoreshwa ryambere rya MRI.

Indi ngingo ikwiye kwitabwaho ni uko mugihe cyo gusikana umurwayi, ni ngombwa gutera inshinge zitandukanye mumubiri wumurwayi. Kandi ibi bigomba kugerwaho hifashishijwe agutandukanya inshinge. LnkMedni uruganda ruzobereye mu gukora, guteza imbere, no kugurisha imiti itandukanye ya siringi. Iherereye i Shenzhen, Guangdong, mu Bushinwa. Ifite uburambe bwimyaka 6 yiterambere kugeza ubu, kandi umuyobozi wikipe ya LnkMed R&D afite Ph.D. kandi afite uburambe bwimyaka irenga icumi muruganda. Gahunda y'ibicuruzwa by'isosiyete yacu byose yabyanditse. Kuva yashingwa, inshinge za LnkMed zitera inshinge zirimoCT inshusho imwe itandukanye itanga inshinge, CT inshinge ebyiri, MRI itandukanya inshinge, Angiografiya itera umuvuduko mwinshi, (kandi na syringe hamwe nigituba gikwiranye nibirango bivaMedrad,Guerbet,Nemoto, LF, Medtron, Nemoto, Bracco, SINO,Seacrown) yakirwa neza n'ibitaro, kandi ibice birenga 300 byagurishijwe mu gihugu no hanze yacyo. LnkMed burigihe ishimangira gukoresha ubuziranenge nkibipapuro byonyine byungurana ibitekerezo kugirango utsinde ikizere cyabakiriya. Ninimpamvu yingenzi ituma ibicuruzwa byacu byumuvuduko ukabije wibicuruzwa bya syringe byemerwa nisoko.
