A brief explanation of these "test yourself"questions:

•  Group 1 tests your ability to identify technical information:  windows used, planes shown, and use of contrast
   
•  Group 2 relates to important non-radiological information printed on the scans such as patient name, exam date, & location of the scale.
     
•  Group 3 lets you test your ability to identify abnormalities on the scans, including changes in size, shape, symmetry, density, displacement, integrity, grey-white differentiation, and lesion formation.
          
•  Group 4 tests your knowledge of CT anatomy of the brain.
