Prediction of Tissue Damage Using a User-Independent Machine Learning Algorithm vs. Tmax Threshold Maps

Test the accuracy of a fully automated stroke tissue estimation algorithm (FASTER) to predict final lesion volumes in an independent dataset in patients with acute stroke and found the decision forest algorithm overestimated the final infarct volume in patients without reperfusion.

Performance of Machine Learning for Tissue Outcome Prediction in Acute Ischemic Stroke: A Systematic Review and Meta-Analysis

Machine learning (ML) has been proposed for lesion segmentation in acute ischemic stroke (AIS). This study aimed to provide a systematic review and meta-analysis of the overall performance of current

Radiomics, machine learning, and artificial intelligence—what the neuroradiologist needs to know

Deep radiomics uses CNNs to directly extract features and obviate the need for predefined features and common limitations and pitfalls in AI-based research in neuroradiology are limited sample sizes, selection bias, as well as overfitting and underfitting.

Deep Learning in Ischemic Stroke Imaging Analysis: A Comprehensive Review

The current state-of-the-art deep learning technology in acute ischemic stroke imaging is surveyed, particularly in exploring the potential function of stroke diagnosis and multimodal prognostication.

Stroke Lesion Outcome Prediction Based on MRI Imaging Combined With Clinical Information

This work proposes an automatic deep learning-based method for stroke lesion outcome prediction, which resides in the combination of multi-modal Magnetic Resonance Imaging maps with non-imaging clinical meta-data: the thrombolysis in cerebral infarction scale, which categorizes the success of recanalization, achieved through mechanical thrombectomy.

Enhancing clinical MRI Perfusion maps with data-driven maps of complementary nature for lesion outcome prediction

The ability of the proposed approach to improve prediction of tissue at risk before therapy, as compared to only using the standard clinical perfusion maps, is demonstrated, suggesting on the potential benefits of the data-driven raw perfusion data modelling approach.

It is concluded that prediction of tissue damage in the event of either persistent occlusion or immediate and complete recanalization, from spatial features derived from MRI, provides a substantial improvement beyond predefined thresholds.

Towards automatic MRI volumetry for treatment selection in acute ischemic stroke patients

This work proposes a novel, more elaborate image analysis approach that is based on supervised classification methods to automatically segment and predict the extent of the tissue compartments of interest (healthy, infarct, penumbra regions).

Prediction of Tissue Outcome and Assessment of Treatment Effect in Acute Ischemic Stroke Using Deep Learning

A predictive model capable of automatically identifying and combining acute imaging features to accurately predict final lesion volume and seems to be able to differentiate outcomes based on treatment strategy with the volume of final infarct being significantly different.

ISLES 2016 and 2017-Benchmarking Ischemic Stroke Lesion Outcome Prediction Based on Multispectral MRI

The Ischemic Stroke Lesion Segmentation challenge, which has ran now consecutively for 3 years, aims to address the problem of comparability by providing a uniformly pre-processed data set and allowing new approaches to be compared directly via the online evaluation system.
