Machines are noisy, and often children cannot lie still long enough to get proper images. It uses quite a lot of X-rays, and so it is important to make sure we do not use it on too many people if it can be avoided.Īn MRI scan uses no X-rays, and gives more detailed pictures, but takes much longer. It's quick and often is the best first-line investigation, but it does not give as detailed pictures as an MRI. Most children will have a CT or an MRI scan, which looks in detail at the inside of the brain.Ī CT scan uses X-rays. They’ll usually check other things like balance, coordination, sensation and reflexes. This will include looking into the back of your child’s eyes with an ophthalmoscope to check for swelling, which can be a sign of raised pressure in the brain. Your doctor will want to hear about the problems your child has had recently, and will examine him or her properly. The specialist doctor and nurse will explain things but don’t be afraid to ask questions. Knowing what a test involves can make things a bit easier. What happens when a brain tumour is suspected the brain stem – this connects the brain to the spinal cord and is in the lower part of the brain just above the back of the neck it controls breathing, body temperature, heart rate and blood pressure, eye movements and swallowing.the cerebellum – this is the back part of the brain, and it controls movement, balance and coordination.the cerebrum – this is at the top of the head and is the largest part of the brain it's made up of 2 halves (hemispheres), it controls thinking, learning, memory, problem-solving, emotions and touch, and it also helps us be aware of our body position.Between 2 of these layers is a space that contains a fluid called cerebrospinal fluid (CSF), which circulates around the brain and spinal cord. These completely cover the brain and spinal cord and help to protect it. Between the brain and the skull, there are 3 layers of membrane called the meninges. The brain is contained within the skull, which protects it. Some of these symptoms are common even without a brain tumour, and this can cause confusion in the early stages. feeling extremely sleepy (drowsy) for no reasonīrain tumours can also cause problems with balance and walking, weakness down one side of the body, or changes in behaviour.eye problems, such as abnormal eye movements, blurring or double vision feeling very tired much more quickly than usual.feeling very irritated or losing interest in day-to-day things. ![]()
