Frequency of imaging 'depends on age and number of machines available'

    The utilization of imaging on stroke patients is affected by their age as well as the number of magnetic resonance imaging (MRI) and computed tomography (CT) machines within the facility, research has shown.

    A study published in the Journal of the American College of Radiology said that although imaging in stroke patients has been associated with greater life expectancy and lessening cancer mortality rates, one of the reasons behind the growth of imaging could be the increased number of machines available.

    "Our study demonstrates that for patients presenting with symptoms of acute stroke, differences in scanning capacity (CT and MRI) may shape aspects of clinical management," said Max P Rosen, lead author.

    This follows news that a functional magnetic resonance imaging (fMRI) scan could be used to diagnose autism.

    In the study, published in Radiology, scientists measured the neural activity in working brain tissue during passive stimulation.
