During the past several years, the availability of computed tomography (CT) and magnetic resonance imaging (MRI) scanning has grown rapidly. An estimated 
number of CT diagnostic equipment units grew more than 50 percent between 1995 and 2004, while the estimated number of MRI units more than doubled. Apparently, the use of imaging technologies has associated costs and benefits, the question is whether the benefits are more than costs or not? An insightful study conducted by Stanford University researchers recently published brought the issue into the limelight.
