Gano MRI

Tushen jiki na hoton maganadisu na maganadisu (MRI) shine sabon abu na rawan maganadisu na nukiliya (NMR). Don hana kalmar "nukiliya" daga haifar da fargabar mutane da kuma kawar da haɗarin radiation na nukiliya a cikin binciken NMR, al'ummar ilimi na yanzu sun canza karfin maganadisu na nukiliya zuwa karfin maganadisu (MR). Bloch na Jami'ar Stanford da Purcell na Jami'ar Harvard ne suka gano lamarin MR a 1946, kuma su biyun sun sami lambar yabo ta Nobel a Physics a 1952. A 1967, Jasper Jackson ya fara samun alamun MR na kyallen jikin dabbobi. A shekara ta 1971, Damian na Jami'ar Jihar New York a Amurka ya ba da shawarar cewa za a iya amfani da abin da ya faru na karfin maganadisu don gano cutar kansa. A cikin 1973, Lauterbur ya yi amfani da filayen magnetic gradient don magance matsalar matsayi na sararin samaniya na siginar MR, kuma ya sami hoton MR na farko na nau'i biyu na samfurin ruwa, wanda ya kafa harsashin aikace-aikacen MRI a filin likita. Hoton rawanin maganadisu na farko na jikin mutum an haife shi a shekara ta 1978.

A cikin 1980, an sami nasarar samar da na'urar daukar hoto ta MRI don gano cututtuka, kuma an fara aikace-aikacen asibiti. The International Magnetic Resonance Society an kafa bisa ƙa'ida a cikin 1982, yana hanzarta aiwatar da wannan sabuwar fasaha a cikin binciken likita da sassan binciken kimiyya. A cikin 2003, Lauterbu da Mansfield tare sun sami lambar yabo ta Nobel a fannin Physiology ko Medicine don amincewa da manyan binciken da suka yi a binciken binciken hoton maganadisu.
