Journal Article
Kok, Y. E., Pszczolkowski, S., Law, Z. K., Ali, A., Krishnan, K., Bath, P., Sprigg, N., Dineen, R. A., & French, A. P. (2022). Semantic Segmentation of Spontaneous Intracerebral Hemorrhage, Intraventricular Hemorrhage, and Associated Edema on CT Images Using Deep Learning. Radiology: Artificial Intelligence, 4(6), https://doi.org/10.1148/ryai.220096

This study evaluated deep learning algorithms for semantic segmentation and quantification of intracerebral hemorrhage (ICH), perihematomal edema (PHE), and intraventricular hemorrhage (IVH) on noncontrast CT scans of patients with spontaneous ICH. M... Read More about Semantic Segmentation of Spontaneous Intracerebral Hemorrhage, Intraventricular Hemorrhage, and Associated Edema on CT Images Using Deep Learning.

M., & Dineen, R. A. (2022). Effect of Tranexamic Acid Administration on Remote Cerebral Ischemic Lesions in Acute Spontaneous Intracerebral Hemorrhage: A Substudy of a Randomized Clinical Trial. JAMA Neurology, 79(5), 468-477. https://doi.org/10.1001/jamaneurol.2022.0217

Importance: Hyperintense foci on diffusion-weighted imaging (DWI) that are spatially remote from the acute hematoma occur in 20% of people with acute spontaneous intracerebral hemorrhage (ICH). Tranexamic acid, a hemostatic agent that is under invest...

Automated Detection of Candidate Subjects With Cerebral Microbleeds Using Machine Learning (2022)
Journal Article
Sundaresan, V., Arthofer, C., Zamboni, G., Dineen, R. A., Rothwell, P. M., Sotiropoulos, S. N., Auer, D. P., Tozer, D. J., Markus, H. S., Miller, K. L., Dragonu, I., Sprigg, N., Alfaro-Almagro, F., Jenkinson, M., & Griffanti, L. (2022). Automated Detection of Candidate Subjects With Cerebral Microbleeds Using Machine Learning. Frontiers in Neuroinformatics, 15, Article 777828. https://doi.org/10.3389/fninf.2021.777828

Cerebral microbleeds (CMBs) appear as small, circular, well defined hypointense lesions of a few mm in size on T2*-weighted gradient recalled echo (T2*-GRE) images and appear enhanced on susceptibility weighted images (SWI). Due to their small size,... Read More about Automated Detection of Candidate Subjects With Cerebral Microbleeds Using Machine Learning.

Journal Article
Ovesen, C., Jakobsen, J. C., Gluud, C., Steiner, T., Law, Z., Flaherty, K., Dineen, R. A., Christensen, L. M., Overgaard, K., Rasmussen, R. S., Bath, P. M., Sprigg, N., & Christensen, H. (2021). Tranexamic Acid for Prevention of Hematoma Expansion in Intracerebral Hemorrhage Patients With or Without Spot Sign. Stroke, 52(8), 2629-2636. https://doi.org/10.1161/strokeaha.120.032426

Background and Purpose:
The computed tomography angiography or contrast-enhanced computed tomography based spot sign has been proposed as a biomarker for identifying on-going hematoma expansion in patients with acute intracerebral hemorrhage. We inv... Read More about Tranexamic Acid for Prevention of Hematoma Expansion in Intracerebral Hemorrhage Patients With or Without Spot Sign.
