Fig: The essential role of signal processing in magnetic resonance: Upper left: magnetic resonance imaging (MRI); Lower right: magnetic resonance spectroscopy (MRS)

Magnetic resonance spectroscopy (MRS) can provide information about key metabolites, but conventional applications are hampered by data analysis via the fast Fourier transform (FFT). Most MRS studies for cancer detection rely upon estimations of a handful or single composite metabolite, yielding only incrementally improved diagnostic accuracy. In vitro studies reveal richer metabolic information for identifying cancer, particularly in closely-overlapping components, e.g. phosphocholine, a marker of malignant transformation. The FFT cannot assess these congested spectral components. This can be done by the fast Padé transform (FPT), a high-resolution, quantification-equipped method. The FPT accurately extracts the concentrations of all the metabolites, including phosphocholine. These capabilities strongly suggest that by applying the FPT to time signals encoded in vivo from various cancers, MRS will fulfill its potential to become a clinically-reliable, cost-effective method for early cancer detection.
