The
diagnosis and accurate localization of prostatic carcinoma by 3D multivoxel
MR spectroscopy (MRS) analysis is often complicated on a slice-by-slice
basis. A semi-automated individualized method was developed to obtain a 3D
reconstruction of the prostate with superimposition of metabolic results for
an intuitive depiction and rapid localization of the suspicious malignant
zones. The (Cho+Cr)/Cit ratio was calculated in a voxel-by-voxel basis and
used as a metabolic index to be combined with the 3D reconstructions of the
prostate.
