Objectives: To benchmark the performance of state-of-the-art computer-aided detection (CAD) of pulmonary nodules using the largest publicly available annotated CT database (LIDC/IDRI), and to show that CAD finds lesions not identified by the LIDC's four-fold double reading process. The LIDC/IDRI Database is intended to facilitate computer -aided diagnosis (CAD) research for lung nodule detection, classification, and quantitative a ssessment. There are many metrics that Thus, we can compare the average JI of the proposed method with that by Lassen's method and it was observed that the proposed method shows an improvement of 23.1% although Lassen's method interactively defined a stroke as a diameter of GGN. information reported here is derived directly from the LIDC image annotations.

We also include first baseline results. annotation documentation may be obtained from where the slice number is an integer starting at 1 and progressing in the cranio-caudal direction. Preliminary clinical studies have shown that spiral CT scanning of the lungs can improve early detection of lung cancer in high-risk individuals.
