The Challenge provided sets of calibration and testing scans, established a performance assessment process, and created an infrastructure for case dissemination and result submission. In CT lung cancer screening, many millions of CT scans will have to be analyzed, which is an enormous burden for radiologists. Acad Radiol. The purpose of this work is to describe the LUNGx Challenge for the computerized classification of lung nodules on diagnostic computed tomography (CT) scans as benign or malignant and report the performance of participants' computerized methods along with that of six radiologists who participated in an observer study performing the same Challenge task on the same dataset. Lung cancer is the leading cause of cancer-related death worldwide.  |  Our method achieves higher competition performance metric (CPM) scores than the state-of-the-art methods using deep learning. Home - LUNA - Grand Challenge. We provide this list to also allow teams to participate with an algorithm that only determines the likelihood for a given location in a CT scan to contain a pulmonary nodule. J Med Internet Res. Computer-aided Diagnosis for Lung Cancer: Usefulness of Nodule Heterogeneity. The thick solid curve is for radiologist-determined nodule size alone (. A vital first step in the analysis of lung cancer screening CT scans is the detection of pulmonary nodules, which may or may not represent early stage lung cancer. (b) A malignant nodule (arrow) for which the best-performing method returned (correctly) a high likelihood of malignancy score but to which all radiologists assigned lower malignancy ratings. A final important point is that the mean nodule sizes in the data sets of the Vancouver study and the NLST are not equivalent, owing to the different size threshold chosen to report a lung nodule. Nodules for evaluation were demarcated with blue crosshairs. The thick solid curve is for the radiologists as a group. September, 2017: We have decided to stop processing new LUNA16 submissions without a clear description article.
