H-1 and P-31 NMR characterisation of a double breast coil for spectroscopic measurements and imaging

For the first time a double turn breast coil has been described which can b e used for H-1 imaging, H-1 spectroscopy and P-31 Spectroscopy. The paper d escribes basic technical features of the coil, coil design, B-1 field/excit ation field distribution for H-1 and (31)p, sensitivity, and feasibility fo r P-31 spectroscopic in vivo studies. The main advantage of the double freq uency tuneable coil is that H-1 imaging for tumor localization and P-31 spe ctroscopy for response control can be done without an additional reposition ing of the patient.
