Abstract:
Objective To investigate the best techniques and postprocessing protocols for 31P MRS of femur and soft tissue.Methods The 31P MRS was performed on the 20 normal volunteers,using Siemens SONATA 1.5T MR scanner and heart/liver 31P surface coil.The age of volunteers ranged from 18 to 25 years old.Related data came from 40 voxels of the interested region were post-processed and compared by two different kinds of methods: automatically processed(group A) and interactively processed(group B).Results In group A,only 28 of 40 studies displayed well defined spectra,another 12 can't,and the shift of PCr deviated from 0.0 ppm;In group B,35 of 40 studies produced well defined spectra,another 5 can't,and the shift of PCr was near to 0.0 ppm,(p
