About this study

The purpose of this pilot interventional study is to evaluate the use of Dynamic Airway Computed Tomography (DA-CT) for diagnosis of tracheomalacia in children 0-18 years for whom flexible bronchoscopy has been performed. The primary aims are to evaluate the diagnostic accuracy, image quality, and radiation exposure of DA-CT as a potential noninvasive alternative to the gold standard of flexible bronchoscopy in the diagnosis of tracheomalacia. The results from this pilot study will help to estimate sample size for a larger-scale study with more precise estimates of DA-CT diagnostic potential.

What is being measured

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

  1. Number of Participants With Tracheomalacia Identified by DA-CT

    Presence of tracheomalacia identified by the DA-CT procedure (binary).

    Measured: Day 0 (Imaging Visit)

Secondary outcomes (7)
  1. Image Noise in Tracheal Air Column Region of Interest (ROI)

    Image noise was measured from CT attenuation values in the tracheal air-column region-of-interest. Attenuation values within the ROI were recorded in Hounsfield Units (HU), a standardized CT scale in which water is assigned a value of 0 HU and air is assigned a value of approximately -1,000 HU; denser materials have higher HU values. Image noise was calculated as the standard deviation (SD) of those HU values. Higher image noise values indicate greater image noise. Results are summarized using the median and interquartile range (IQR).

    Measured: Day 0 (Imaging Visit)

  2. Image Noise in Largest Imaged Mediastinal Artery ROI

    Image noise was measured from CT attenuation values in the largest imaged mediastinal artery ROI. Attenuation values within the ROI were recorded in Hounsfield Units (HU), a standardized CT scale in which water is assigned a value of 0 HU and air is assigned a value of approximately -1,000 HU; denser materials have higher HU values. Image noise was calculated as the standard deviation (SD) of those HU values. Higher image noise values indicate greater image noise. Results are summarized using the median and interquartile range (IQR).

    Measured: Day 0 (Imaging Visit)

  3. Image Noise in Entire Two-Dimensional Right Lung Measurement ROI

    Image noise was measured from CT attenuation values in the entire 2-D right lung measurement ROI. Attenuation values within the ROI were recorded in Hounsfield Units (HU), a standardized CT scale in which water is assigned a value of 0 HU and air is assigned a value of approximately -1,000 HU; denser materials have higher HU values. Image noise was calculated as the standard deviation (SD) of those HU values. Higher image noise values indicate greater image noise. Results are summarized using the median and interquartile range (IQR).

    Measured: Day 0 (Imaging Visit)

  4. Image Noise in Subcutaneous Fat ROI

    Image noise was measured from CT attenuation values in the subcutaneous fat ROI. Attenuation values within the ROI were recorded in Hounsfield Units (HU), a standardized CT scale in which water is assigned a value of 0 HU and air is assigned a value of approximately -1,000 HU; denser materials have higher HU values. Image noise was calculated as the standard deviation (SD) of those HU values. Higher image noise values indicate greater image noise. Results are summarized using the median and interquartile range (IQR).

    Measured: Day 0 (Imaging Visit)

  5. Image Noise in Ambient Air ROI

    Image noise was measured from CT attenuation values in the ambient air ROI. Attenuation values within the ROI were recorded in Hounsfield Units (HU), a standardized CT scale in which water is assigned a value of 0 HU and air is assigned a value of approximately -1,000 HU; denser materials have higher HU values. Image noise was calculated as the standard deviation (SD) of those HU values. Higher image noise values indicate greater image noise. Results are summarized using the median and interquartile range (IQR).

    Measured: Day 0 (Imaging Visit)

  6. Radiation Exposure of DA-CT Scanners

    Dose length product (DLP), CT radiation dose metric representing the total energy delivered, measured in mGy·cm (milligray-centimeters) used to monitor overall radiation risk and establish reference levels

    Measured: Day 0 (Imaging Visit)

  7. Radiation Exposure of DA-CT Scanners

    Size specific dose estimate (SSDE), computed tomography (CT) radiation dose metric (measured in mGy) that provides a more accurate estimation of the radiation absorbed by a patient compared to the traditional Volume CT Dose Index

    Measured: Day 0 (Imaging Visit)

Questions about this trial

What is this clinical trial studying?

A study testing Dynamic Airway CT scan (DA-CT) in people with Tracheomalacia, run by NYU Langone Health at 2 sites in United States.

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 2 inclusion and 3 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: finished, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

Yes. Results are posted in the registry (first posted 20 Oct 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Tracheomalacia Identified by DA-CT (time frame: Day 0 (Imaging Visit)). 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 20 Oct 2026.
