Fine-tuning deep learning model parameters for improved super-resolution of dynamic MRI with prior-knowledge

作者:

Highlights:

• Alleviates the spatio-temporal trade-off in dynamic MRI using super-resolution

• Model was first trained on a static dataset with different contrast and resolution.

• Static subject-specific planning scan was used to fine-tuned the trained model.

• Achieved a structural similarity of 0.957 while reconstructing 6.25% of the k-space
