Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Screening
Name: Observer nodule detection Type: Behavioral
Name: Computer-aided nodule detection Type: Device
Overall Status
Imaging procedures including chest X-ray and low-dose computed tomography may be effective in lung cancer early detection. Yet it is unknown whether low-dose computed tomography combined with computer aided detection (CAD) is more effective than LDCT in screening of early lung cancer.
Detailed Description
The randomized clinical trial is to investigate and compare the effectiveness of CAD-guided low-dose computed tomography and low-dose computed tomography in lung cancer screening for community individuals in Shanghai, China. Thus, an imaging protocol which can detect early lung cancer in asymptomatic high risk patients will be proposed.
Criteria for eligibility
Healthy Volunteers: Accepts Healthy Volunteers
Maximum Age: 74 Years
Minimum Age: 35 Years

Exclusion Criteria:

- Individuals with any symptoms suggestive of lung cancer (e.g., vigorous coughing, chest pain, weight loss, blood-stained sputum)
