Better performance of deep learning pulmonary nodule detection using chest radiography with pixel level labels in reference to computed tomography: data quality matters

Autor: Jae Yong Kim, Wi-Sun Ryu, Dongmin Kim, Eun Young Kim

Publikováno v: Scientific Reports, Vol 14, Iss 1, Pp 1-9 (2024)

Abstract Labeling errors can significantly impact the performance of deep learning models used for screening chest radiographs. The deep learning model for detecting pulmonary nodules is particularly vulnerable to such errors, mainly because normal c

Subthreshold amyloid deposition, cerebral small vessel disease, and functional brain network disruption in delayed cognitive decline after stroke

Autor: Jae-Sung Lim, Jae-Joong Lee, Geon Ha Kim, Hang-Rai Kim, Dong Woo Shin, Keon-Joo Lee, Min Jae Baek, Eunvin Ko, Beom Joon Kim, SangYun Kim, Wi-Sun Ryu, Jinyong Chung, Dong-Eog Kim, Philip B. Gorelick, Choong-Wan Woo, Hee-Joon Bae

Publikováno v: Frontiers in Aging Neuroscience, Vol 16 (2024)

BackgroundAlthough its incidence is relatively low, delayed-onset post-stroke cognitive decline (PSCD) may offer valuable insights into the “vascular contributions to cognitive impairment and dementia,” particularly concerning the roles of vascul

Publikováno v: Journal of Stroke, Vol 26, Iss 2, Pp 300-311 (2024)

Background and Purpose Accurate classification of ischemic stroke subtype is important for effective secondary prevention of stroke. We used diffusion-weighted image (DWI) and atrial fibrillation (AF) data to train a deep learning algorithm to classi

Autor: Jung Hoon Han, Sue Young Ha, Hoyeon Lee, Gi-Hun Park, Hotak Hong, Dongmin Kim, Jae Guk Kim, Joon-Tae Kim, Leonard Sunwoo, Chi Kyung Kim, Wi-Sun Ryu

Publikováno v: Frontiers in Neurology, Vol 15 (2024)

IntroductionWe developed and externally validated a fully automated algorithm using deep learning to detect large vessel occlusion (LVO) in computed tomography angiography (CTA).MethodA total of 2,045 patients with acute ischemic stroke who underwent

Trends in Dual Antiplatelet Therapy of Aspirin and Clopidogrel and Outcomes in Ischemic Stroke Patients Noneligible for POINT/CHANCE Trial Treatment

Publikováno v: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, Vol 13, Iss 10 (2024)

Background Recent clinical trials established the benefit of dual antiplatelet therapy with aspirin and clopidogrel (DAPT‐AC) in early‐presenting patients with minor ischemic stroke. However, the impact of these trials over time on the use and ou

Publikováno v: Frontiers in Neuroscience, Vol 18 (2024)

BackgroundWe compared the ischemic core and hypoperfused tissue volumes estimated by RAPID and JLK-CTP, a newly developed automated computed tomography perfusion (CTP) analysis package. We also assessed agreement between ischemic core volumes by two

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-10 (2023)

Abstract We hypothesized that the association between BP and endovascular treatment (EVT) outcomes would differ by baseline perfusion and recanalization status. We identified 388 ICA or M1 occlusion patients who underwent EVT ≤ 24 h from onset with
