The Lung Image Database Consortium wiki page on TCIA contains supporting documentation for the LIDC/IDRI collection. This collection contained 70 cases of Lung scan acquired using different CT scanners. Seven academic centers and eight medical imaging companies collaborated to identify, address, and resolve challenging organizational, technical, and clinical issues to provide a solid foundation for a robust database. Sheng Wu Yi Xue Gong Cheng Xue Za Zhi. LIDC is defined as Lung Image Database Consortium frequently. The goal of this process was to identify as completely as possible all lung nodules in each CT scan without requiring forced consensus. LIDC stands for Lung Image Database Consortium. (b) A lesion depicted in two adjacent CT sections that is outlined by all four radiologists in the more superior section (left) but only by two radiologists in the more inferior section (right) (outlines not shown). Acad Radiol. The TCIA distribution was made available early in July 2011 and is hosted at Details on CT scans with importing issues and scans for which no nodule 38(2) 915–931 (2011) Google Scholar. For information on other image database click on the "Databases" tab at the top The intent of this initiative was “to support a consortium of institu-tions to develop consensus guidelines for a spiral CT lung image resource, and to construct a database of spiral CT lung images” (42). The size information presented here is to augment the LIDC/IDRI database [2]. To stimulate the advancement of computer-aided diagnostic (CAD) research for lung nodules in thoracic computed tomography (CT), the National Cancer Institute launched a … Methods: L. E. Quint, L. H.

In collaboration with the I-ELCAP group we have established two public image databases that contain lung CT images in the DICOM format together with documentation of abnormalities by radiologists. Initiated by the National Cancer Institute (NCI), further advanced by the Foundation for the National Institutes of Health (FNIH), and accompanied by the Food and … The Lung Image Database Consortium (LIDC): an evaluation of radiologist variability in the identification of l ung nodules on CT scans.

Kuhn, E. Dharaiya, CONCLUSION The two-phase image annotation process yields improved agreement among radiologists in the interpretation of nodules >or=3 mm. The identifier or identifiers of the nodule boundaries used for the volume estimation of that physical nodule. In this article, a comprehensive data analysis of the data set and a uniform data model are presented with the purpose of facilitating potential researchers … MATERIALS AND METHODSThe evaluation of the impact of different size metrics was performed on whole-lung CT scans that were documented by the Lung Image Database Consortium (LIDC). The nodule size list provides size estimations for the nodules identified (b) The nested outline of one radiologist reflects the radiologist’s opinion that a region of exclusion (a dilated bronchus) exists within the nodule. mm. Purpose: [(b) and (c)] The outlines constructed on this section by two of the radiologists. 2007 Nov;14(11):1409-21. doi: 10.1016/j.acra.2007.07.008. Four size metrics, based on the boundary markings, … In this study, the authors present a comprehensive and the most updated analysis of this dynamically growing database under the help of a computerized tool, aiming to assist researchers to optimally use this database for lung cancer related investigations. The digits after the last dash in the Subject ID (the other part is constant and equal to LIDC-IDRI-). Lung Image Database Consortium listed as LIDC Looking for abbreviations of LIDC? He, K., Zhang, X., Ren, S., Deep, S.J. A unique multi-center data collection process and communication system were developed to share image data and to capture the location and spatial extent of lung nodules as marked by expert radiologists. SH: Shape heterogeneity. At: /lidc/, October 27, 2011. annotation documentation may be obtained from the size-selected subrange of nodules that they The inner outline is explicitly noted as an exclusion in the XML file. 2669 of these lesions were marked "nodule > or =3 mm" by at least one radiologist, of which 928 (34.7%) received such marks from all four radiologists.
