Alors que les scanners IRM normaux fonctionnent entre 1,5 et 3 Tesla, le scanner IRM \u00e0 faible champ peut faire presque le m\u00eame travail \u00e0 0,05 Tesla.<\/h2>\n

Les scanners IRM sont des merveilles de technologie et constituent un outil important pour les m\u00e9decins qui souhaitent poser un diagnostic. Pour cr\u00e9er des scanners \u00e0 haute r\u00e9solution, vous devez vous assurer que le signal est bien sup\u00e9rieur au bruit \u00e9lectromagn\u00e9tique qui nous entoure. Plus le champ de l’IRM est \u00e9lev\u00e9, plus il est facile de cr\u00e9er des scans \u00e0 haute r\u00e9solution. Cela signifie \u00e9galement que le scanner a besoin d’une salle de contr\u00f4le et qu’il ne peut pas changer de place.<\/p>\n

Mais aujourd’hui, les universit\u00e9s et les instituts de recherche se concentrent sur une autre approche : le scanner IRM \u00e0 faible champ, avec des r\u00e9sultats tr\u00e8s int\u00e9ressants. Le scanner \u00e0 faible champ utilise beaucoup moins d’\u00e9nergie et vous pouvez le brancher sur une prise normale. Les niveaux de radiation sont faibles, vous n’interf\u00e9rez pas avec d’autres fr\u00e9quences. Gr\u00e2ce \u00e0 ces deux sp\u00e9cificit\u00e9s, cette nouvelle technologie est tr\u00e8s int\u00e9ressante pour les endroits \u00e9loign\u00e9s et difficiles d’acc\u00e8s. Le scanner est relativement petit (compar\u00e9 aux scanners IRM normaux) et facile \u00e0 transporter. Vous pouvez amener le scanner au patient plut\u00f4t que le patient au scanner.<\/p>\n

\"\"<\/p>\n

Le champ bas mesure \u00e9galement les champs \u00e9lectromagn\u00e9tiques autour du scanner. Gr\u00e2ce \u00e0 des algorithmes d’apprentissage profond, ils filtrent le signal du bruit, ce qui am\u00e9liore la r\u00e9solution de la mesure.<\/p>\n

\"\"<\/p>\n

La r\u00e9solution de la technologie \u00e0 faible champ est nettement inf\u00e9rieure \u00e0 celle d’un scanner IRM normal, mais dans la plupart des cas, elle est suffisante pour \u00e9tablir un premier diagnostic et l’utiliser pour les premiers traitements. Voir l’image de la Yale School of Medicine.<\/p>\n

Veuillez consulter l’\u00e9cole de m\u00e9decine de Yale<\/a> pour plus d’informations – recherchez \u00ab\u00a0Low field MRI\u00a0\u00bb (IRM \u00e0 faible champ) pour trouver plus de documentation sur la recherche.<\/p>\n","protected":false},"excerpt":{"rendered":"
