About this study

Official title: Novel High Fidelity Functional Lung Imaging in Adults Undergoing Radiation Therapy to Assess for Radiation Pneumonitis

The purpose of this study is to to compare lung function data generated by applying High Fidelity Functional Lung Imaging (HFFLI) software to 4D CT, cone beam CT, and fluoroscopic images of the lungs breathing to determine whether different modalities of imaging provide similar data on lung movement and function. HFFLI may detect changes in lung function in patients undergoing External Beam Radiotherapy for cancer.

Read the detailed description

This study is designed to test a novel technology to examine early changes in the lung in hopes of identifying patients who may be at risk for radiation pneumonitis. Eligible subjects will undergo standard of care treatment with the use of the Varian TrueBeam system for radiation therapy of a cancer lesion in the chest. The imaging data acquired as part of usual standard of care for these patients is a pre-treatment 4D planning CT scan, and a daily cone beam CT at each radiation treatment visit. We will also obtain a series of images consisting of five six-second cinefluorographs (real time fluoroscopic movies, for a total each time of 30 seconds of fluoroscopy) of the lungs while the subject is breathing, each at precisely measured angles to the subject, on 4 different occasions. This study will compare lung function data generated by applying High Fidelity Functional Lung Imaging (HFFLI) software to 4D CT, cone beam CT, and fluoroscopic images of the lungs breathing to determine the degree of correlation between data generated from different imaging modalities. The study is open to adults over the age of 18, at any stage of cancer.

Being tested
4D Computed Tomography (CT), Cone Beam CT, Low-dose Cinefluorography, Pulmonary Function Tests
Medical subject headings
Lung Neoplasms, Breast Neoplasms, Radiation Pneumonitis

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 4D Computed Tomography (CT)Radiation

    The initial 4DCT imaging obtained as part of a subject's planning CT for their standard radiation treatment.

  • Cone Beam CTRadiation

    Daily cone beam CT imaging at each radiation treatment visit, as part of standard care

  • Low-dose CinefluorographyRadiation

    Also called Fluoroscopic images

    A series of images consisting of five six-second cinefluorographs (real time fluoroscopic movies, for a total each time of 30 seconds of fluoroscopy) of the lungs while the subject is breathing, each at precisely measured angles to the subject, on 4 different occasions.

  • Pulmonary Function TestsDevice

    Pulmonary Function Testing (PFT) gives global functional data for the lungs as a whole, but is relatively insensitive to early pathological changes. It involves taking very deep breaths and exhaling as forcefully as possible.

    Research PFTs will be conducted at 4 and 12-months post radiation therapy

Study groups in NCT02735746
Study groupRoleWhat they receive
High fidelity functional lung imagingHigh fidelity functional lung imaging (HFFLI) is an improved method of measuring pulmonary function by analyzing 3-Dimensional (3D) motion. Using this technique, we are able to detect and localize pathological changes in the lung with sub-segmental resolution. The approach uses a unique cross-correlation analysis and non-linear optimization to reconstruct lung tissue motion from a small number of standard projections. All participants will undergo standard 4D Computed Tomography (CT), standard Cone Beam CT, research Low-dose Cinefluorography, and additional research Pulmonary Function Tests.

Questions about this trial

What is this clinical trial studying?

An observational study of Lung Cancer and Breast Cancer, run by Cedars-Sinai Medical Center at 1 site 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 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: finished, as of the sponsor's last update on 22 Aug 2025. 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

A Pearson correlation of >0.579 between peak expiratory flow as measured by HFFLI analysis of cinefluorograph compared with 4D planning CT (time frame: Baseline). The study lists 12 primary outcomes in all. 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 22 Aug 2025.
