Automated Detection of Cerebral Microbleeds on Two-dimensional Gradient-recalled Echo T2* Weighted Images Using a Morphology Filter Bank and Convolutional Neural Network
CONCLUSION: Through effective CMB candidate refinement with a morphology filter bank and FP removal with a CNN, we achieved a high CMB detection rate and low FP count. Combining a CNN and morphology filter bank may facilitate the accurate automated detection of CMBs on T2*WIs.PMID:38494702 | DOI:10.2463/mrms.mp.2023-0146 (Source: Magnetic Resonance in Medical Sciences)

Imaging of < sup > 17 < /sup > O-labeled Water Using Fast T2 Mapping with T2-preparation: A Phantom Study
Magn Reson Med Sci. 2024 Mar 15. doi: 10.2463/mrms.tn.2023-0152. Online ahead of print.ABSTRACT17O-labeled water is a T2-shortening contrast agent used in proton MRI and is a promising method for visualizing cerebrospinal fluid (CSF) dynamics because it provides long-term tracking of water molecules. However, various external factors reduce the accuracy of 17O-concentration measurements using conventional signal-intensity-based methods. In addition, T2 mapping, which is expected to provide a stable assessment, is generally limited to temporal-spatial resolution. We developed the T2-prepared based on T2 mapping used in card...

Reproducible Spinal Cord Quantitative MRI Analysis with the Spinal Cord Toolbox
Magn Reson Med Sci. 2024 Mar 12. doi: 10.2463/mrms.rev.2023-0159. Online ahead of print.ABSTRACTThe spinal cord plays a pivotal role in the central nervous system, providing communication between the brain and the body and containing critical motor and sensory networks. Recent advancements in spinal cord MRI data acquisition and image analysis have shown a potential to improve the diagnostics, prognosis, and management of a variety of pathological conditions. In this review, we first discuss the significance of standardized spinal cord MRI acquisition protocol in multi-center and multi-manufacturer studies. Then, we cover ...
