Clinical diagnosis of a number of diseases is seldom performed without resorting to multimodality imaging technology in the era of personalized and precision medicine. Among the existing plethora of imaging techniques, Computed Tomography (CT) plays a pivotal role in the clinical setting owing to widespread availability of equipment and expertise as well as acceptance of this technology. Yet, medical radiation exposure of patients has become an important public health concern worldwide. Significant efforts by the vendors to improve CT scanners technology and by medical physicists and radiologists to optimize acquisition protocols have significantly reduced the radiation dose from CT examinations to address the concerns of patients and general public driven by unprecedented levels of radiophobia or radiation hysteria.
