Ukunqongophala kweHelium kukhuthaza ingqiqo entsha yongxamiseko kuluntu olusebenzisa imifanekiso yezonyango

I-NBC News isandula ukubika ukuba iingcali zezempilo zixhalabile ngakumbi ngehlabathii-heliumukunqongophala kunye nempembelelo yako kwicandelo le-magnetic resonance imaging.I-HeliumKubalulekile ukugcina umatshini we-MRI upholile ngelixa usebenza. Ngaphandle kwawo, iskena asinakusebenza ngokukhuselekileyo. Kodwa kwiminyaka yakutshanje, ihlabathi liphelai-heliumukubonelela ngeenkonzo kuye kwatsala ingqalelo enkulu, kwaye abanye ababoneleli baqalise ukulinganisela into engahlaziyekiyo.

Nangona oku bekuqhubeka kangangeminyaka elishumi nangaphezulu, iindaba zamva nje ngalo mba zibonakala zongeza ingqiqo yongxamiseko. Kodwa ngenxa yesiphi isizathu?

Njengakwiingxaki ezininzi zokubonelela ngeenkonzo kwiminyaka emithathu edlulileyo, ubhubhane ngokungathandabuzekiyo ushiye iimpawu ezithile ekunikezelweni nasekuhanjisweni kweenkonzo.i-heliumImfazwe yaseUkraine nayo yaba nefuthe elikhulu ekunikezelweni kwezixhoboi-heliumKude kube kutshanje, iRashiya bekulindeleke ukuba inike amandla ombane afikelela kwisithathu se-helium yehlabathi evela kwiziko elikhulu lemveliso eSiberia, kodwa umlilo obangelwe yile ndawo ulibazise ukuqaliswa kwesi sikhungo kwaye imfazwe yeRashiya eUkraine iye yandisa ubudlelwane bayo nobudlelwane bezorhwebo base-US. Zonke ezi zinto zidibene nokwenza iingxaki zothungelwano lokubonelela zikhule ngakumbi.

UPhil Kornbluth, umongameli weKornbluth Helium Consulting, wabelane neNBC News ukuba i-US ibonelela malunga nama-40 ekhulwini eemveliso zehlabathi.i-helium, kodwa isiqingatha sesine kwisihlanu sababoneleli abaphambili belizwe baqalile ukuxabiswa. Njengababoneleli abasandula ukubandakanyeka ekunqongophaleni kwe-iodine contrast, ababoneleli be-helium bajika baye kwiindlela zokunciphisa eziquka ukubeka phambili amashishini aneemfuno ezibalulekileyo, ezifana nokhathalelo lwempilo. Ezi ntshukumo azikaguquleli ekurhoxisweni kweemviwo zomfanekiso, kodwa sele zibangele ukothuka okwaziwayo kuluntu lwezenzululwazi nophando. Iinkqubo ezininzi zophando zaseHarvard ziyavalwa ngokupheleleyo ngenxa yokunqongophala, kwaye i-UC Davis kutshanje yabelane ngokuba omnye wababoneleli babo unciphise izibonelelo zabo phakathi, nokuba zezonyango okanye akunjalo. Le ngxaki ikwatsale ingqalelo yabavelisi be-MRI. Iinkampani ezifana ne-GE Healthcare kunye ne-Siemens Healthineers beziphuhlisa izixhobo ezisebenzayo ngakumbi kwaye zifuna imali encinci.i-heliumNangona kunjalo, ezi ndlela azikasetyenziswa kakhulu okwangoku.
