Which is better CT scan or MRI for brain?

Spine – MRI is best at imaging the spinal cord and nerves. Brain – CT is used when speed is important, as in trauma and stroke. MRI is best when the images need to be very detailed, looking for cancer, causes of dementia or neurological diseases, or looking at places where bone might interfere.

Would a CT scan without contrast show a brain tumor?

This is usually done with injection of an x-ray contrast (dye), though CT scan done even without the x-ray contrast is also sufficient as the first imaging test. MRI with injection of contrast is a more definitive and detailed imaging test which can detect or rule out a brain tumor in most cases.

Can a CT scan without contrast detect a brain tumor?

What can a brain MRI diagnose?

What are different types of brain MRI?

What are the different types of MRI scan we used? Localizer scan – this very short scan (12 seconds) allows the scanner to work out exactly where your brain is inside the magnet. T1-weighted scan – the first long scan and the most important structural scan for our research.
