The water deprivation test allows doctors at Great Ormond Street Hospital (GOSH) to measure how concentrated your child’s urine (wee) becomes when he or she is not drinking. The test can take up to seven hours to complete.
An MRI (magnetic resonance imaging) scan uses a magnetic field rather than X-rays to take pictures of your child’s body. The MRI scanner is a hollow machine with a tube running horizontally through its middle. ‘Feed and wrap’ is a technique used with young babies instead of sedation or general anaesthesia. Generally, babies tend to fall asleep after a feed, so we take advantage of this and scan them while asleep.
