Incidental findings in lung cancer screening: What to report?
Speaker: Hans-Ulrich Kauczor, Heidelberg/DE | Moderator: Mathias Prokop, Nijmegen/NL

General description, scope and objectives of this webinar
The programme of this webinar will cover the most important comorbidities and incidentals findings in lung cancer screening CT. It is aimed at thoracic/chest radiologists, radiology residents/juniors, students and everybody who are interested in the ESTI LCS certification project and want to improve their skills in:
– the detection and categorization of comorbidities and incidental findings
– the decision to not report insignificant incidental findings
– the management of actionable incidental findings

After listening to the webinar, participants will:
– have gained insight in the rationale of comorbidities and incidental findings of low dose CT in LCS
– have learnt about the significance of cardiovascular and obstructive airway disease for mortality in the LCS population and the Big 3 approach
– have consolidated knowledge about incidentals as being actionable, reportable and not-reportable
– be aware of statements and guidance on management of important incidentals

The programme of this webinar will cover a summary of results of lung cancer screening studies. It is aimed at thoracic/chest radiologists, radiologist residents/juniors, students and people who are interested in the ESTI LCS certification project who want to improve their skills in:- Building a CT protocol for performing LCS at the recommended radiation dose level
– About the essential parts that influence a lung cancer program
– About the results of randomized and non-randomized trials thus far

After listening to the webinar, participants will:
– Compare the set ups of the various studies and their impact on results
– Appreciate new insights that have been gained after the publication of the two randomized trials, the NLST and the Nelson trial

Technical requirements for LCS: How to perform the acquisition, how to read the scans and the role of AI
Speaker: Constance De Margerie-Mellon, Paris/FR | Moderator: Thomas Frauenfelder, Zurich/CH

General description, scope and objectives of this webinar
This webinar will cover CT technical requirements and standardized reading criteria for LCS and will also underline the role of AI in chest CTs performed for LCS. 
Meeting the technical requirements when performing chest CTs in the framework of LCS is important, to ensure a satisfying image quality while respecting the recommended radiation dose thresholds. Using appropriate and consistent reading criteria is also critical. As most detected nodules during screening are benign, such criteria allow adequate active management in case of suspicious nodule and imaging follow-up in indeterminate cases, while avoiding overdiagnosis. Finally, AI applications in LCS are booming and the number of AI-based commercial software is constantly growing. Strengths and weaknesses of AI for LCS will be discussed.
It is aimed at thoracic/chest radiologists, radiologist residents/juniors, students and people who are interested in the ESTI LCS certification project who want to improve their skills in:
– Building a CT protocol for performing LCS at the recommended radiation dose level
– Knowing about existing reading criteria for prevalent and incident lung nodules discovered on screening CTs
– Reviewing the potential role of AI for lung nodule detection, lung nodule classification, and for detection of associated comorbidities

After listening to the webinar, participants will:
– Apply the recommended technical requirement for performing chest CT in the LCS framework
– Indicate the adequate management for lung nodules detected during LCS
– Use AI tools for lung nodule detection while being aware of their limitations
