Imaging techniques: A review

Abstract

Computed Tomography (CT) and Positron Emission Tomography (PET) are nowadays within the most employed imaging techniques for the screening and the identification of multiple pathologies, including lung cancer. Medical imaging is a field in continuous development to increase the employment of non-invasive techniques in diagnosis. For the screenings or detection of tumor masses, the use of these techniques can reduce the stress for the patient avoiding a surgical intervention and its risks. Moreover, imaging can be used as a preclinical tool for the decision making process for the most suitable treatment without the necessity of directly intervene in an invasive way.
