This work proposes incorporating quantitative imaging principles during generative SSL to improve image quality and quantitative biological accuracy and shows that this training schema results in better starting states for downstream supervised training on limited data.
Timing the Ischemic Stroke by Multiparametric Quantitative Magnetic Resonance Imaging
- MedicineStroke
- 2021
Exploiting advanced technologies such as Magnetic Resonance Fingerprinting, artificial intelligence (AI), and machine learning (ML) for the post-processing of MRI data, combined with fast MRI techniques, is expected to speed up the translation of objective stroke timing procedures into patient management.

In their more granular approach, the authors try and stress that technical development not only relies on the traditional steps but often, sequential sub-steps that need to be performed in the assessment of a new technology.
T2w-MRI signal normalization affects radiomics features reproducibility.
- MedicineMedical physics
- 2020
Evaluating the effect of three different normalization techniques, applied on T2w-MRI images of the pelvic region, on radiomic features reproducibility concluded that Norm_Mean and Norm_HM seem to provide the most reproducible features with respect to the original image and also between themselves, whereas Norm_ROI generates the less reproducible.
