Magnetic resonance spectroscopic imaging (MRSI) spectra obtained using a conformal voxel approach for areas of normal tissue (green voxel), and suspected abnormality (red voxel) and for short (TE = 40 ms), and long (TE = 130 ms) echo times. A spectral-spatial RF pulse sequence was used. In a normal voxels are displayed demonstrating the appearance of short TE metabolites (i.e., sI—scyllo-inositol) not evident at longer echo times. Similarly, in b there is a decrease in relative concentration of citrate to choline over voxels with suspected cancer
