Low-field magnetic resonance system (LF-MRS) for producing a high-Q MRI image, said LF-MRS comprising: a. Low-field magnetic resonance device (LF-MRD); said LF-MRD is characterized by Q-value, Q MRD , such that the Q-value of said LF-MRS, QMRS, is a function F 1 of said Q MRD , represented by F 1 (Q MRD ); b. a cryogenically cooled RF coil in connection with said LF-MRD; said cryogenically cooled RF coil is characterized by Q-value, Q RF , c. a contrast agent (CA) adapted to be introduced into a specimen prior to the introduction of said specimen into said RF coil; The affect of said F 6 on said Q MRS is significantly greater than the affect of said of predetermined function G on said Q MRS , said function G is represented by either one of: G(F 1 , F 2 , F 3 , F 4 , F 5 ); G(F 1 ); G(F 2 ); G(F 3 ): G(F 4 ); G(F 5 ). |
