Clinical MRS studies in humans [1] are usually performed with standard axial field RF surface coils (circular or rectangular loop). MRS applications [2] require high sensitivity from tissues located at some distance from the coil surface and low contamination from deeper tissues. Transverse field RF coils, comprising one [3] or two [4-5] linear elements centrally positioned, were recently developed to overcome sensitivity and/or selectivity limitations. In this work, we report the use of a versatile figure-of-eight (FO8) transverse field RF surface coil that improves proton MRS at 1.5 T.

Abstract
Clinical MRS studies in humans [1] are usually performed with standard axial field RF surface coils (circular or rectangular loop). MRS applications [2] require high sensitivity from tissues located at some distance from the coil surface and low contamination from deeper tissues. Transverse field RF coils, comprising one [3] or two [4-5] linear elements centrally positioned, were recently developed to overcome sensitivity and/or selectivity limitations. In this work, we report the use of a versatile figure-of-eight (FO8) transverse field RF surface coil that improves proton MRS at 1.5 T.File in questo prodotto:
