Application of Dual-Energy CT Gemstone Spectral Imaging (DECT GSI) in the Characterization of Ground-glass nodules (GGNs)
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
Dual-Energy CT Gemstone Spectral Imaging (DECT GSI) is a new application of a fundamental physics concept that uses rapid kV switching to acquire the dual energy samples almost simultaneously to generate material density data that can be used for the separation of materials and derivation of monochromatic spectral images using a projection based reconstruction algorithm. DECT GSI of lungs allow for detection and Characterization of lung lesions including solid and ground glass nodules (GGNs) [1, 2]. Spectral CT plays a pivotal role in the detection, characterization, and staging of lung cancer. It acquires CT datasets at both low- and high-kVp settings that can improve diagnostic information for clinicians to quantify and separate materials – such as calcium, iodine and water – enhancing image quality, and reducing artifacts from implanted devices [3]. In this review article, we will outline the usefulness of dual-energy CT for the assessment of Ground-glass nodules (GGNs). In addition, we discuss the physical principles of dual- energy CT and potential future applications in patients with GGNs.
