## Abstract A method for estimating the spectral parameters from a noisy FID is proposed. The method uses a priori information concerning the lower and upper limits between which such parameters' values can exist. Computer simulation results show that, using the proposed method, values of the spect

The ability to map spectroscopic components for in vivo application is a highly desirable goal. Thusfar it has been unavailable because of the low SNR inherent in the measurement of each voxel. In this paper we deal with this low SNR in two ways. First, estimation theory, using a priori data, is use
## Abstract We have compared various methods of __in vivo__ NMR spectral parameter estimation, namely a nonlinear fit of the free induction decay signal in the time domain (NLTD), a nonlinear fit of the fast Fourier transform of the FID data in the frequency domain using either a continuous Lorentz
