    Thank you in advance
    This is a qualitative question involving images. You need to find images of both bone and tissue for the two types of imaging (X-ray and MRI) and then note everything you can about why they are:

    a) similar
    b) different

    both in terms of sharpness, contrast and definition. Look up the description for each of these words. I suggest looking at technical-photography and television broadcasting websites for further research. here is a good example: http://www.imatest.com/docs/iqfactors/


    Try making a weighted mark-scheme table for advantages and disadvantages for both tissue and bone mapping and use that to form a rudimentary qualitative assessment. e.g. What does an MRI scan tell you that an X-ray cannot and vice-versa? What are you looking for in both image types? Which type gives a better definition for the outline of bone? Does bone density affect the image? Does an x-ray give depth information, i.e. layered structure, image resolution etc?

    (For ideas, look at the way the judgement criteria is presented in tabular form in the link I provided)

    The key is doing your own research and then devising a way to present the information as objectively and succinctly accurate as possible. Finally make a qualitative judgement based on the evidence for which type is best suited to the tasks in hand.
