Novel MRI Sequence MR Fingerprinting in Breast MRI Feasibility Study

Overview

The purpose of this study is to evaluate potential clinical efficacy of a novel magnetic resonance imaging (MRI) approach, MR fingerprinting, capable of providing quantitative measures of important tissue properties, which could provide important insights into normal breast tissue. This new MRI sequence will be added to the screening breast Dynamic Contrast Enhanced (DCE) MRI for high risk normal patients.

This is a feasibility study of the use of the additional MR fingerprinting (MRF) scanning sequence with a total of 12 minutes scanning time to our clinical screening breast DCE MRI examination before contrast medium injection and at the end of scan. This additional scanning sequence may provide faster and better quantitative tissue characterization comparing to conventional MR sequences. There is no investigational contrast agent in this study. We propose that the additional MRF sequence may provide faster and more accurate tissue characteristics imaging for clinical evaluation of breast tissue. Patients will be enrolled in with scheduled high risk screening DCE MRI (n=30). The MR imaging will be performed in the clinical 1.5T MR scanners in UNC as normally done for the patients MRI schedule. We only add an additional MRF sequence within the MRI exam just prior to the contrast enhancement scan. Quantitative measurement of the breast tissue will be performed after the MR exam. The region-of-interest (ROI) of normal breast parenchyma was recorded. The ROI will be saved and encoded to the T1 map, T2 map in MRF, T1 weighted imaging, T2 weighted imaging. A large variety of imaging ROI-based quantitative measures will be calculated among normal glands in bilateral breasts to evaluate different ROI characteristics among different patients and between bilateral breasts in each patient.
