The Prone to Supine Breast MRI Trial
A study testing Prone to Supine MRI in people with Breast Cancer, run by Dartmouth-Hitchcock Medical Center at 1 site in United States.
Trial summary
The purpose of this study is to determine whether a supine MRI obtained immediately after a standard diagnostic prone MRI exam, without a second injection of gadolinium (Gd) contrast material, would be of sufficient quality to allow the Radiologist to define the tumor edges ("segment" the tumor) so that a 3-D image of… Read more about this study

About this study
The purpose of this study is to determine whether a supine MRI obtained immediately after a standard diagnostic prone MRI exam, without a second injection of gadolinium (Gd) contrast material, would be of sufficient quality to allow the Radiologist to define the tumor edges ("segment" the tumor) so that a 3-D image of the tumor can be generated to form a BCL.
Read the detailed description
The purpose of this study is to find out whether additional MRI images taken with patients in a different position after completing a standard MRI are of sufficient quality to allow a radiologist to identify the edges of the tumor.
These additional MRI images will only take about 10-15 minutes to obtain and will not require a second injection of contrast material.The information gathered in this study will make it more feasible to use a new device called the "breast cancer locator" to help surgeons more accurately remove breast cancers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Prone to Supine MRIOther
The patient will be placed in the prone position and undergo a standard Gd contrast-enhanced bilateral breast MRI. Immediately after the prone MRI is completed, the patient will be repositioned for the supine MRI. Prior to starting the prone MRI, the study MRI technician/investigator will explain to the patient and practice with the patient the steps needed to transition from the prone to the supine MRI, so as to facilitate a timely transition. Additional MRI images will only take about 10-15 minutes to obtain and will not require a second injection of contrast material.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Successful Segmentation of Supine MRI Images
Determine what number of cases that can be successfully segmented both from using post-contrast prone MRI images and also from using post contrast supine MRI images.
Measured: 30 minutes
Secondary outcomes (5)
Enhancement Quantification, as Measured by Signal Intensity - Segmented Tumor
Compare the signal intensity with that obtained at tumor location on the prone and supine imaging. The amount of enhancement at the tumor site = segmented tumor.
Measured: 30 minutes
Enhancement Quantification, as Measured by Signal Intensity - Tumor Boundary
Compare the signal intensity with that obtained in benign tissue surrounding the tumor on the prone and supine imaging.
Measured: 30 minutes
Enhancement Quantification- Tumor-to-Background Ratio
Mean MRI signal of the segmented tumor divided by the mean MRI signal of the surrounding tissue which has an equal volume to the tumor. The difference between tumor and benign breast tissue is the tumor-to-background ratio
Measured: 30 minutes
Time to Position and Obtain Supine Images
Calculate the additional time needed to obtain supine MRI images. After the completion of Prone imaging, the patient was removed from the MRI, turned over to the supine position, new coils placed, and returned to the MRI for additional imaging. The aggregate time to accomplish these tasks are noted in minutes.
Measured: 30 Minutes
Overall Comfort for Prone and Supine Positions
Quantify the perceived comfort level of the prone and supine MRI as reported by participants. A single question using a Likert scale was was used. The scale range was 0 to 5, where 0 = no pain, completely comfortable and 5 = considerable discomfort.
Measured: Within 15 minutes of the scan
