✦ Synopsis

Convection within the sample is a serious problem affecting diffusion measurements, in particular at elevated temper-

atures. Convection currents are caused by small temperature gradients in the sample and cause additional signal decay that can be mistaken for faster diffusion. Recently, sophisticated multidimensional diffusion-ordered techniques such as DOSY (1, 2), DOSY-NOESY (3), COSY-DOSY (4),

Frequency-modulated rf pulses based on a linear frequency sweep are studied experimentally in spin-echo and stimulated-echo sequences. It turns out that these FM pulses generate a quadratic phase perpendicular to the selected slice and that the quadratic phases of the FM pulses in a spin-echo or sti

## Abstract Attempts to use a stimulated echo acquisition mode (STEAM) in cardiac imaging are impeded by imaging artifacts that result in signal attenuation and nulling of the cardiac tissue. In this work, we present a method to reduce this artifact by acquiring two sets of stimulated echo images w

## Exchange of longitudinal spin polarization by dipolar cross relaxation between nonequivalent spins results in a modulation of the stimulated echo signal on increasing the encoding/decoding delays and in a multiexponential decay on increasing the diffusion time. These artifacts are suppressed by
