Workshop Agenda

Workshop Syllabus

LIDC Overview

• motivation: the need for computerized lung nodule detection and evaluation methods in thoracic CT, the current research climate, and the need for research standards and an image resource
• LIDC mission
• LIDC members
• overview of subsequent presentations

Nodule Inclusion Criteria

• spectrum of focal abnormalities
• nodule definition: visual review
• size and number limitations
• presence of other pathology

Spatial "Truth" Determination

• location of all abnormalities to be indicated (by approximate center of mass)
• spatial extent of "qualifying" nodules required for CAD research
• manual vs. (semi-)automated margin outlines (vs. bounding box)
• pitfalls in referring to such delineations as "truth"
• consensus vs. probabilistic margins

Pathologic "Truth"

• need for pathologic ground truth
• World Health Organization (WHO) classification of lung tumors
• confirmation procedure for histopathology and cytologic diagnoses
• whole lung specimens for CT-pathology correlation

Process Model

• clinical source of CT scans
• CT scan inclusion criteria
• CT scan task classification
• data collection process model

Assessment Methodologies

• the sample size issue and its practical impact on the efforts of the LIDC
• how the many potential uses of the database complicate the ability to statistically characterize the database
• the need for and limitations of a proposed pilot study
• the role of score-keeping methods, truth-determination paradigms, and performance metrics in CAD research

The End Product

• description of the anticipated results of the LIDC effort
• expected manner in which the database will be used by researchers
• timeline for database population and public release
• mechanism for receiving feedback from the research community

Open Forum

• initiate with discussion points from an LIDC panel directed at the audience, such as:
  • How will the existence of this database affect your own research?
  • What other information should be supplied with the database?
  • How can the database be used to positively direct CAD research within the community?
• open floor
