Magnetic Resonance Imaging (MRI) machine with an integrated medical table top on which a patient can lie is provided. The table top has a central polypropylene cellular honeycomb structure thermally fused in a sandwich configuration between two fibre-reinforced polypropylene face sheets. A strip of fibre-reinforced polypropylene is thermally fused along the entire length of the edge of the sandwich layers and along the end sections of the strip so that the resultant package of layers and end strip is sealingly enclosed to form the tabletop. Table top has a cover which may have a paint or acrylic finish, or may be foamed or “soft-touch” or suitably coated, in order to enhance the patients comfort and to ensure that tabletop is hard-wearing and readily cleanable.
