What are CAT and MRI scans?

Computed tomography (Computer Assisted Tomography - CAT scan) requires a combination of a special x-ray machine and a computer. The computer stores a series of 'cuts' and a series of pictures can be produced at varying levels of the body part that has been x-rayed. It can be beneficial in the assessment of gynaecological tumours.

Magnetic resonance imaging (MRI) is a non-invasive technique that provides images of body structures. Before entering an MRI scanner, the patient must remove all metallic objects including jewellery and watches. A powerful electromagnet causes the nuclei of atoms (particularly hydrogen in water molecules) to align magnetically. Radio waves are used to detect the position of these atoms and these are analysed by computer. Bones do not hamper the picture so the technique is particularly helpful for looking inside the skull. In gynaecology, MRI may provide a detailed assessment of the pituitary gland (hyperprolactinaemia).
