{ "DOI": "10.1038/s41598-021-91467-x", "abstract": "There is little evidence on the applicability of deep learning (DL) in the segmentation of acute ischemic lesions on diffusion-weighted imaging (DWI) between magnetic resonance imaging (MRI) scanners of different manufacturers. We retrospectively included DWI data of patients with acute ischemic lesions from six centers. Dataset A (n=2986) and B (n=3951) included data from Siemens and GE MRI scanners, respectively. The datasets were split into the training (80%), validation (10%), and internal test (10%) sets, and six neuroradiologists created ground-truth masks. Models A and B were the proposed neural networks trained on datasets A and B. The models subsequently fine-tuned across the datasets using their validation data. Another radiologist performed the segmentation on the test sets for comparisons. The median Dice scores of models A and B were 0.858 and 0.857 for the internal tests, which were non-inferior to the radiologist's performance, but demonstrated lower performance than the radiologist on the external tests. Fine-tuned models A and B achieved median Dice scores of 0.832 and 0.846, which were non-inferior to the radiologist's performance on the external tests. The present work shows that the inter-vendor operability of deep learning for the segmentation of ischemic lesions on DWI might be enhanced via transfer learning; thereby, their clinical applicability and generalizability could be improved.", "author": [ { "family": "Alis", "given": " Deniz" }, { "family": "Yergin", "given": " Mert" }, { "family": "Alis", "given": " Ceren" }, { "family": "Topel", "given": " Cagdas" }, { "family": "Asmakutlu", "given": " Ozan" }, { "family": "Bagcilar", "given": " Omer" }, { "family": "Senli", "given": " Yeseren Deniz" }, { "family": "Ustundag", "given": " Ahmet" }, { "family": "Salt", "given": " Vefa" }, { "family": "Dogan", "given": " Sebahat Nacar" }, { "family": "Velioglu", "given": " Murat" }, { "family": "Selcuk", "given": " Hakan Hatem" }, { "family": "Kara", "given": " Batuhan" }, { "family": "Oksuz", "given": " Ilkay" }, { "family": "Kizilkilic", "given": " Osman" }, { "family": "Karaarslan", "given": " Ercan" } ], "container_title": "SCIENTIFIC REPORTS", "id": "235848", "issue": "1", "issued": { "date-parts": [ [ 2021, 1, 1 ] ] }, "title": "Inter-vendor performance of deep learning in segmenting acute ischemic lesions on diffusion-weighted imaging: a multicenter study", "type": "article-journal", "volume": "11" }
