Article Synopsis
- Silent MRA, enhanced by a new deep learning algorithm from GE HealthCare, effectively evaluates stent performance for treating intracranial aneurysms.
- The study involved implanting two Surpass Evolve stents in silicone tubes to assess lumen visibility using different MRA techniques, including TOF and silent MRA.
- Results indicated that silent MRA provided better signal intensity ratios and reduced artifacts compared to TOF images, showcasing its potential for improved assessment of stent function.
Exploiting 4D-flow magnetic resonance imaging (MRI) data to quantify hemodynamics requires an adequate spatio-temporal vector field resolution at a low noise level. To address this challenge, we provide a learned solution to super-resolve 4D-flow MRI data at a post-processing level. We propose a deep convolutional neural network (CNN) that learns the inter-scale relationship of the velocity vector map and leverages an efficient residual learning scheme to make it computationally feasible.
