The
results analyzed from 3.0 T were consistent with our previous findings using 1.5T
with a lower spatial resolution, suggesting that the limitation of MRI in
diagnosis of post-NAC cancer cannot be improved with a higher SNR or a higher
spatial resolution. Our current protocol at 3.0 T still could not detect
residual tumor presenting as scattered cells or small foci, which often
occurs in non-mass-like lesions. These types of invasive cancer cells do not
need angiogenesis to survive, and if so, they will not show contrast
enhancements.
