About this study

Official title: Multi-Centered Study Comparison of Output Images From STrategically Acquired Gradient Echo to Conventional 1.5 T and 3.0 T Magnetic Resonance Images and Assessing Their Clinical Usability on Human Participants

The study's purpose is to validate STAGE images and, when applicable, their equivalence to conventional MRI through an assessment by a trained certified neuroradiologist in a clinical setting. For STAGE images without conventional equivalent, the neuroradiologist will determine if their contrasts, intensities, and quality are sufficient and meet expectations for images used in radiological reads of the brain. The study is a multi-center study in which STAGE can be assessed at sites with different MRI manufacturers and field strengths. Site names will be made available to the collaborators and participants. The sponsor is based out of Michigan, while participating sites may be located in other states. Any funding for the study will come from an industry source, SpinTech, Inc.

Read the detailed description

The scope of the study includes the acquisition of MR images from a specified MR manufacturer, the installation of the STAGE device at the clinical site, the subsequent processing of the acquired MR images, and their evaluation by neuroradiologists. The follow section will summarize the key procedures which are involved in this study.

  1. Participants will be enrolled as study subjects per IRB approved protocol and informed consent.
  2. The STAGE device will be installed at the clinical site. The installation of the Investigational STAGE module requires it to be labeled for Investigational Use Only, per FDA requirements. It requires an available power source and live Ethernet connection. STAGE is connected to the PACS via a node which requires the AE title and an assigned IP address. The node will only accept images which meet the STAGE protocol requirements and any other images are not used. After the images are processed and sent back to the PACS system, all data are purged from the STAGE module. A log is kept of which data was processed which can be viewed through the assigned IP within a web browser. All images under the study protocol shall be labeled "For Investigational Device Use Only".
  3. The PI and Co-Investigators will be trained on the use of installed STAGE investigational device. This will include a review of the installation and user manuals written as documentation under the FDA regulated development process. Documentation of the training process will be documented with data workflow and output images being presented.
  4. After these steps the clinical study collection of MR images will begin. Since a primary aim of STAGE is to reduce acquisition times while generating a wealth of contrasts from the dataset, additional conventional MR images will be acquired including but not limited to: T1W, Susceptibility Weighted Images (SWI), Magnetic Resonance Angiography (MRA), and Spin Density Weighted (PDW). The patient's time in the magnet will be kept under 40 minutes. The STAGE protocol is available for Siemens, GE, Philips, and Canon/Toshiba magnets at both 1.5T and 3.0T field strengths. The processed STAGE images will be sent back to the PACS system where they remain within the participant's scan folder and are clearly labeled. They can then be viewed at an integrated workstation.
  5. The study data will then be collected on Case Report Forms to record the response from the reading radiologist as well as the documented acquisition times for the STAGE protocol and the standard of care acquisition times used within that clinical setting (control arm of study). Prospective data will include imaging as well as questionnaire/survey with the radiologist to evaluate the performance of STAGE and its outputs. The study will not consist of retrospective data.
  6. Clinical study completions and closeout. At the conclusion of the study, STAGE will be removed from the site by a trained technician and all data from the study will be purged from the PACS. A checklist will be documented to show that all measurable clinical response metrics have been recorded and that the study has successfully contributed its intended aims while following IRB and FDA regulations for clinical studies.

What participants receive

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

  • STrategically Acquired Gradient Echo (STAGE)Device

    The STAGE package uses conventional 3D gradient echo MR, its magnitude and phase, collected at set parameters which allow for the reconstruction of multiple MR datasets which results in decreased acquisition time, equivalency to conventional MR, and the decrease in scan time allows for a higher standard of wealth within the data acquired.

Study groups in NCT04292301
Study groupRoleWhat they receive
STrategically Acquired Gradient Echo (STAGE)ExperimentalSTAGE Inputs are flow compensated 3D gradient echo MR images acquired at optimal parameters which are used to calculate multiple contrasts for brain imaging. All subjects within the study are imaged using both a conventional MR protocol and STAGE protocol.
Receives: Device: STrategically Acquired Gradient Echo (STAGE)

What is being measured

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

  1. Numeric Rating Scale of Clinical Usability Assessment of STAGE Outputs

    Reading radiologists responses on the clinical usability of STAGE Outputs based on image quality using a numeric rating scale of 1 to 5 with: 1=unacceptable, 2=poor, 3=acceptable, 4=good, 5=excellent. Scores of 3 or greater are considered clinically usable.

    Measured: Baseline Only

  2. Review of STAGE Outputs for Artifact and Image Contrast

    Reading radiologist and image analyst responses on the clinical usability of STAGE Outputs based on image quality using a yes/no criteria for presence of novel or accentuated imaging artifact. Hardware or participant artifact contributions (i.e. coil sensitivity and motion) were not considered unless noted as increased due to the STAGE method. Each image series was evaluated for the presence of artifact. The total count of the artifacts reported across series evaluated in the study is reported.

    Measured: Baseline Only

  3. Review of STAGE Outputs for Expected Brain Structural Appearance

    Reading radiologists responses on the clinical usability of STAGE Outputs based on image appearance of specified brain structures using pass/fail criteria. Expected brain contrast between tissue types will vary depending on the output reviewed (i.e. T1W, PDW, SWI). The behavior of tissue contrasts (i.e. white matter vs gray matter) should also demonstrate standard anatomic contrast (T1W, PDW, SWI) as well quantitative ratio for maps (T2*MAP, R2*MAP, SWIM, T1MAP, PDMAP). For artery/vein appearance, STAGE T1W, T1MAP and PD MAP were not evaluated due to artery/vein not appearing in the image contrasts. For GM/WM/CSF, the MRA, pSWIM and mpSWIM were not evaluated due to the anatomic contrast not appearing in the image contrasts. For calcium/iron appearance, T1WE, T1MAP, PDMAP, MRA, and DIR were not evaluated due to the calcium/iron not appearing in the image contrasts.

    Measured: Baseline Only

  4. Evaluation of STAGE Image Processing Times

    Review of the recorded processing times for the STAGE module to accept and process STAGE inputs and to export them back to the PACS as STAGE outputs.

    Measured: Baseline Only
