The Xelis Lung solution provides a realistic alternative for review of large thin datasets, problem solving and double reading of chest CT. Solid nodules and GGOs have a detection rate of over 80%. The detection rate of a CAD system was superior to that of a radiologist for the nodules 5 mm or smaller. With enhanced sensitivity, it increases the detection rate of pulmonary nodules and diagnosis by radiologists. Its Automatic Lung Nodule Detection also provides the accurate volume size of the nodule. Determining the growth rate of the detected nodule is important in judging the need for a biopsy.
