Concurrent water T and fat fraction mapping of the breast using the radial gradient and spin echo (RADGRASE) pulse sequence. Magnetic resonance imaging, 118, 110355.More infoThis work describes and evaluates an efficient radial gradient- and spin-echo (RADGRASE) pulse sequence and reconstruction algorithm for concurrent measurement of proton-density weighted fat fraction (FF) and water component T (T) within breast tissues. The ability to estimate T in breast tissues, where fat can be highly abundant, is demonstrated using oil/gel phantoms across a wide range of FF values (0.1-0.7). Successful T mapping of breast tissues is also demonstrated in vivo by comparison with fat suppressed T values. The sensitivity of RADGRASE to detect changes in the breast was assessed by tracking T in 3 healthy volunteers through their menstrual cycle, demonstrating T values in the late luteal phase to be 18-29 ms higher than in the follicular phase. The technique is also applied to a cohort of 68 patients taking tamoxifen for breast cancer risk reduction, where significant positive correlation between the FF parameter Frac50 and T (p = 0.035) was observed in premenopausal subjects (n = 20). Our findings demonstrate the ability and efficacy of RADGRASE for simultaneously mapping FF and T within breast tissues, and the potential utility of the technique in studying breast tissue changes in clinical applications.

JCO oncology practice, 21(5), 647-653.More infoThe factors affecting women's willingness to participate (WTP) in breast cancer (BC) prevention trials are poorly understood. This study aimed to identify the characteristics of interventions associated with a higher WTP among high BC risk women.
