Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) in Frequent Orbital and Optical Path Pathologies. A Review

Abstract

<em><strong>Objective:</strong></em> To determine the clinical applications of the computed axial tomography (CAT) and the magnetic resonance imaging (MRI) in the diagnosis and management of some frequent orbit and optical path pathologies. Materials and <em><strong>Methods:</strong></em> A bibliometric review was conducted by using search strategies in the Pubmed and Medline databases, among others. Results and Discussion: With this review, the preferred exam for some authors between 2009 and 2012 for frequent orbital and optical path pathologies was identified. However, during the search process, it became evident that some of them showed similar frequencies during a determined period, while others showed significant changes in the test of choice through the years, which would make it possible to ensure that both techniques are complementary for the diagnosis, the treatment and the follow-up of the pathology. Nevertheless, it is necessary to recognize the clinical manifestations, because they would have a predictive value when choosing the diagnostic exam; it is likewise important to highlight the benefit of early detection of mortal pathologies, which has favored research in preventive medicine, given that imaging is crucial in the assessment of the extension of ocular disease, retrobulbar extension and intracranial metastasis in certain cases.
