Non-inferiority of Deep Learning Acute Ischemic Stroke Segmentation on Non-Contrast CT Compared to Expert Neuroradiologists

Autor: Ostmeier, Sophie, Axelrod, Brian, Verhaaren, Benjamin F. J., Christensen, Soren, Mahammedi, Abdelkader, Liu, Yongkai, Pulli, Benjamin, Li, Li-Jia, Zaharchuk, Greg, Heit, Jeremy J.

Publikováno v: Sci Rep 13, 16153 (2023)

To determine if a convolutional neural network (CNN) deep learning model can accurately segment acute ischemic changes on non-contrast CT compared to neuroradiologists. Non-contrast CT (NCCT) examinations from 232 acute ischemic stroke patients who w

USE-Evaluator: Performance Metrics for Medical Image Segmentation Models with Uncertain, Small or Empty Reference Annotations

Autor: Ostmeier, Sophie, Axelrod, Brian, Bertels, Jeroen, Isensee, Fabian, Lansberg, Maarten G., Christensen, Soren, Albers, Gregory W., Li, Li-Jia, Heit, Jeremy J.

Performance metrics for medical image segmentation models are used to measure the agreement between the reference annotation and the predicted segmentation. Usually, overlap metrics, such as the Dice, are used as a metric to evaluate the performance
