I wnt Seminar topic on Mri scanning of brain using matlab. Pls hlp me

There are over 100 different types of brain tumours. They are commonly named after the type of cell they come from. Most brain tumours develop from glial cells, which grow from the supporting cells of the brain. These tumours are called ‘gliomas’. Tumours that begin in the brain are known as primary brain tumours.
Some types of brain tumours are malignant (cancerous) and others are benign (non-cancerous). Differences include:
Benign brain tumours – are often slow growing and are unlikely to spread, but they can press on and damage the surrounding brain tissue. Usually, this type of tumour can be successfully removed with surgery.
Malignant brain tumours – vary in how fast they grow and respond to treatment. Some are contained inside a capsule and are easy to remove, while others have thin filaments spreading through the brain that make them very difficult to take out.


Diagnosis of brain tumours

If your doctor suspects a brain tumour, you will be referred to a specialist doctor called a neurologist or neurosurgeon.

Some of the tests they will do may include:
neurological examination – such as checking your muscle strength, reflexes, memory and your ability to tell hot from cold on your skin (sensation tests)
eye test – the optic nerve, which connects the eye to the brain, tends to bulge a little if a tumour is present at the front of the brain
CT scan – three dimensional x-rays. A dye will be injected or swallowed if you are having a full body scan, so that anything unusual will show more clearly
magnetic resonance imaging (MRI) – similar to a CT scan, but magnetism is used to create a picture. This test will almost certainly show up any brain tumour
x-rays and blood tests – to test your general health
angiogram – injected dye is x-rayed as it flows through the blood vessels of your brain. This is not done for all types of brain tumours.
There may be other scans and tests that you will need to help diagnose your tumour. This will depend on the type of tumour you have and whether it has spread to other parts of your body.

Test results can take a few days to come back. It is very natural to feel anxious waiting to get your results. It can help to talk to a close friend or relative about how you are feeling. You can also contact the Cancer Council Helpline on 13 11 20 and speak with a cancer nurse.
