ABSTRACT
In recent years there have been numerous technological developments in radiology that help physicians in their evaluations of colorectal patients. Radiological studies include plain radiographs, contrast enemas, ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET scan). With this diversity of choice, an understanding of the benefits and limitations of the different radiological procedures is helpful in determining which is the most useful examination for a particular problem [1]. This chapter presents a brief analysis of the strengths and weaknesses of the various radiological procedures so that, in consultation with a diagnostic radiologist, one can select the appropriate imaging study.
