Background:

Lung cancer is a leading cause of cancer mortality worldwide.
Low-dose computed tomography (LDCT) is crucial for early-stage lung cancer screening.
Automated systems can enhance the accuracy and efficiency of cancer screening.

Purpose of the Study:

To develop an artificial intelligence (AI) framework for lung cancer screening using deep neural networks (DNNs).
To create a system for detecting lung nodules (LNs) and classifying their malignancy from LDCT images.
To evaluate the performance of the AI system against human experts.

Main Methods:

A semi-automated annotation strategy was employed for image labeling.
DNN-based models were developed for LN detection and benign/malignancy classification.
The system, named DeepLN, was trained and validated on a large-scale dataset of LDCT images.

Main Results:

The DeepLN system achieved high sensitivity for LN detection (96.5% and 89.6% in different subsets).
Benign or malignancy identification showed excellent performance with 92.46% accuracy, 95.93% specificity, and 90.46% precision.
Retrospective clinical comparisons demonstrated a high detection accuracy of 99.02% for DeepLN compared to human experts.

Conclusions:

An AI-based system (DeepLN) was developed to enhance lung cancer screening performance and radiologist efficiency.
The system's effectiveness was validated through retrospective clinical evaluation.
The DeepLN system shows potential for improving patient outcomes and societal benefits in lung cancer screening.
