DCE-MRI protocol is the reference technique to
detect and characterize breast lesions. Due to the high spatial resolution
needed to detect small lesions, the temporal resolution of the DCE-MRI protocol
is limited to 90 seconds. A good fat suppression is also needed and a spectral
inversion preparation is commonly used for it. To provide more information about
lesion vascularization, temporal resolution need to be increased. We have
developed a method to implement a smart k-space trajectory allowing both
standard DCE-MRI protocol reconstruction and accelerated DCE-MRI protocol via
Compressed-Sensing reconstruction compatible with fat suppression.
