About this study

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

The purpose of this study is to predict the CT visual score of emphysema with EIT-based parameters, in order to provide a non-invasive and convenient method for the evaluation of lung structure and physiological and pathological progression of COPD.

Read the detailed description

Methods: By collecting pulmonary function data, CT visual scores, and EIT data, and employing deep machine learning algorithms to compare the predictive capabilities of EIT and PFT for CT visual scores of pulmonary emphysema, this study aims to validate the ability of EIT to assess the progression of COPD.

Medical subject headings
Pulmonary Disease, Chronic Obstructive

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The predictive power of EIT and PFT for CT visual scoring of emphysema

    the prediction accuracy between deep machine learning models based on PFT data and EIT data

    Measured: 1 mounths

Questions about this trial

What is this clinical trial studying?

An observational study of Electric Impedance and Respiratory Function Tests, run by Chinese PLA General Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Zhimei Duan, doctor (13716376758, 549117002@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The predictive power of EIT and PFT for CT visual scoring of emphysema (time frame: 1 mounths). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2024; AzTrials last refreshed its copy on 1 Nov 2026.
