Influence of virtual dynamic contrast enhanced breast MRI on lesion size, BI-RADS scores and reader confidence.

BACKGROUND Breast MRI routinely uses gadolinium-based contrast agents (GBCAs) for dynamic contrast-enhanced (DCE) imaging. However, GBCA administration entails periprocedural effort and environmental impact, prompting exploration of contrast-agent-free approaches. Deep learning-based virtual DCE (vDCE) offers a potenti...

Fast and robust q-space trajectory imaging using voxel-wise multilayer perceptrons for parameter estimation.

It is concluded that a simple MLP can provide high-quality QTI parameter estimates from short tensor-valued diffusion acquisitions, which enables five-minute, high-resolution QTI and may encourage further clinical studies of markers such as microscopic fractional anisotropy.

Constrained estimation of rotational invariants of the cumulant expansion (RICE) for rapid tensor-valued diffusion MRI

Fast dMRI protocols for obtaining rotational invariants of the cumulant expansion were paired with constrained weighted linear least squares (CWLLS) to stabilize the more fragile WLLS fit, yielding high-quality parameter maps at an online-ready computational cost.
