ABSTRACT
This chapter presents recent advances in lung-cancer imaging, with emphasis on the latest developments in lung-cancer imaging such as positron emission tomography (PET), endobronchial ultrasound (EBUS), and molecular imaging. With the advent of multidetector computed tomography (MDCT), there has been considerable improvement in the scanning techniques that allow scanning of the whole chest within a single breath-hold using a thin-section, high-resolution technique. Integrated PET and CT is a new imaging modality offering both anatomic localization and metabolic information of lesions. PET has now become a clinically useful, noninvasive study that complements conventional imaging studies in the evaluation of patients with lung cancer. With an improvement in the accuracy of imaging through the use of PET, possibilities of understaging and overstaging have reduced tremendously, leading to an appropriate treatment for that particular stage.
