✦ Synopsis

Dedicated low-Ðeld (0.1 T) resistive magnets equipped with solenoid coils were devised for high-resolution and rapid magnetic resonance imaging (MRI) in agricultural and food science. The maximum pixel resolution is 0.1 Â 0.1 mm with a 0.8 mm slice thickness, and 3D and weighted images are obtained in 3 s-6 min depending T 1

, T 2 T 2 * on the contrast and number of slices. In place of resistive magnets two desktop permanent magnet designs are also described and their Ðeld characteristics and possible usefulness for small-sized low-cost MRI scanners, are discussed.
