Storage moduli, loss moduli, and elastic contrasts at 50 Hz of the various components in the MRE breast phantom

TM material 50 Hz ELF storage modulus (kPa) 50 Hz ELF loss modulus (kPa) 50 Hz ELF el. contrast
Fibroadenoma 91.7 ± 1.8 9.6 ± 0.9 2.8 ± 0.2
Cancer 59.1 ± 5.6 7.1 ± 1.9 1.8 ± 0.2
Glandular 32.3 ± 1.9 4.6 ± 0.7 1
Fat sphere 16.3 ± 1.0 3.8 ± 0.3 0.50 ± 0.04
SF 15.2 ± 0.5 5.8 ± 0.6 0.47 ± 0.03

Measurements were made 16 months after production of the phantom. SF = subcutaneous fat; el. contrast = elastic contrast.
