Using electrical impedance tomography to predict COPD severity

Prediction of COPD Chest CT Severity Using Electrical Impedance Tomography by Machine Learning Methods

Chinese PLA General Hospital · NCT06359145

This study is testing if a new non-invasive method using electrical signals can help predict how severe COPD is in patients compared to standard lung tests.

What this trial studies

This study aims to predict the severity of chronic obstructive pulmonary disease (COPD) by utilizing electrical impedance tomography (EIT) to assess lung structure. It involves collecting pulmonary function data, CT visual scores, and EIT data, and applying deep machine learning algorithms to evaluate the predictive capabilities of EIT compared to traditional pulmonary function tests. The goal is to establish a non-invasive method for monitoring the progression of COPD.

Who should consider this trial

Good fit: Ideal candidates include individuals over 20 years old who exhibit symptoms of COPD but have not yet received a definitive diagnosis through pulmonary function tests.

Not a fit: Patients who refuse the EIT examination or have incomplete CT scan information may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a more accessible and non-invasive method for evaluating and monitoring COPD severity.

How similar studies have performed: While the use of EIT in assessing lung conditions is emerging, this specific application for predicting COPD severity is relatively novel and has not been extensively tested in prior studies.

Eligibility criteria
