    a) CAT scans take 3-D images by taking cross sectional pictures and piecing them together; whilst x-rays only take 2-D images.

    I’m sure you can figure out why this would be an advantage! Plus you can see brain activity :) .

    Do your own work, though. This stuff is all over the internet.
