Collage of multiple cross sections through a single guava. The guava has been virtually sliced along a horizontal axis from left to right, giving you a bird's eye view into the centre of the fruit (axial or transverse plane). A series of sequential ultra-thin slices through the entire fruit were taken and selected slices from that series are shown here. These images were acquired by spin-echo magnetic resonance imaging (MRI) which reveals details inside the guava without damaging it. The images are digitally coloured where contrast corresponds to MRI signal intensity and hue was changed to match the natural colour of the fruit.
