Water in soft materials (living matter) often shows a high degree of translational mobility, giving rise to relatively long magnetic relaxation times. This allows the use of conventional MRI techniques such as the spin-echo, to acquire an image. However, when hydration levels become low, water becomes less mobile, resulting in much shorter magnetic relaxation times and a corresponding signal loss. To avoid problems arising from rapid decaying signals, we investigated the use of single point imaging (SPI) in the study of seeds. We were able to obtain SPI images of nonimbibed and imbibed seeds. Using SPI with shaped gradients significantly reduced the acoustic noise level.
