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.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | 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. | 30 minutes | |
Secondary | 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. | 30 minutes | |
Secondary | 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. | 30 minutes | |
Secondary | 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 | 30 minutes | |
Secondary | 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. | 30 Minutes | |
Secondary | 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. | Within 15 minutes of the scan |
