Spin-echo experiment with NMR spectra only partially narrowed by an insufficiently fast motion.
The spin-echo experiment on a spin system with only partial motional narrowing and an exponential field autocorrelation function is considered. The pattern of the intensity decrease in the echo spectra depends on t...

Influence of Parameters on Image Quality Using Fast Spin Echo (FSE) and Comparison with the Conventional Method of Spin Echo (SE)
The article deals with the effects of parameters TE (echo time), ETL (echo train length) and ETE (effective echo time) in the FSE method. The images are compared in terms of signal / noise ratio (SNR). The importance of the...

Optimization of diffusion‐weighted single‐refocused spin‐echo EPI by reducing eddy‐current artifacts and shortening the echo time
of diffusion-weighted (DW) single-refocused spin-echo (srSE) data without intrinsic eddy. The rationale is that srSE sequences without ECC may yield shorter echo times (TE) and thus higher signal-to-noise ratios (SNR) than...
