Study summary

This is an observational, multicentre study. The primary objective of this study was to evaluate the diagnostic performance and clinical applicability of artificial intelligence models for pulmonary nodule segmentation, benign-malignant risk stratification, and follow-up management. We will collect CT images and medical data from participants at several hospitals. Participants will not receive any drugs or medical interventions.

In context

Multiple Pulmonary Nodules

99 studies on the registry are indexed under Multiple Pulmonary Nodules; 42 are open to participants now.

This study's planned enrollment of 16,880 is above the median of 255 across 51 observational studies indexed under Multiple Pulmonary Nodules.

Study population

Consecutively enrolled, representative patients (aged ≥18 years, with a maximum nodule diameter of ≥3 mm and ≤30 mm) who underwent chest CT for routine clinical care and were found to have pulmonary nodules, including solid, part-solid, and pure ground-glass nodules.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

(1) Age ≥18 years; (2) At least one non-calcified pulmonary nodule (diameter ≥3 mm and ≤30 mm) detected on chest CT; (3) Agreement to participate in the study and provision of written .

Exclusion criteria

Exclusion Criteria:

  1. Poor CT image quality with severe artifacts that preclude AI-based analysis;
  2. Expected survival \<12 months or inability to complete follow-up;
  3. History of prior ipsilateral lung or local treatment. -
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Groups and cohorts

  • Benign Pulmonary Nodule Group

    Participants with pulmonary nodules diagnosed as benign, confirmed by either pathological examination or stability on follow-up imaging. No intervention is applied.

  • Malignant Pulmonary Nodule Group

    Participants with pulmonary nodules diagnosed as malignant, confirmed by pathological examination. No intervention is applied.

What researchers measure

Primary outcomes

  1. Diagnostic performance of the AI model for pulmonary nodule malignancy

    Area under the receiver operating characteristic curve (AUC), sensitivity, and specificity of the AI model for classifying benign and malignant nodules, using pathology results or longitudinal stability as the reference standard.

    Time frame: Up to 24 months after enrollment

Secondary outcomes

  1. Risk stratification accuracy across different nodule sizes

    The ability of the AI model to correctly stratify nodules into low, intermediate, and high-risk categories compared to clinical judgement.

    Time frame: Up to 24 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Oct 2026; primary completion for Oct 2028, 24 months later.

Of 24 observational studies under Multiple Pulmonary Nodules, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 62. This study's planned 24 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
