Dual‐Sensitivity Multiple Sclerosis Lesion and CSF Segmentation for Multichannel 3T Brain MRI

Abstract: BACKGROUND AND PURPOSEA pipeline for fully automated segmentation of 3T brain MRI scans in multiple sclerosis (MS) is presented. This 3T morphometry (3TM) pipeline provides indicators of MS disease progression from multichannel datasets with high‐resolution 3‐dimensional T1‐weighted, T2‐weighted, and fluid‐attenuated inversion‐recovery (FLAIR) contrast. 3TM segments white (WM) and gray matter (GM) and cerebrospinal fluid (CSF) to assess atrophy and provides WM lesion (WML) volume.METHODSTo address nonuniform d… Show more

“…The output provided brain T2 hyperintense lesion volume (T2LV) and brain parenchymal fraction (BPF), a surrogate of whole brain atrophy. This pipeline showed high accuracy and reliability 23. Intraclass correlation coefficients of 0.95, 0.91, and 0.86 were obtained for T2LV, CSF, and BPF accuracy.…”

“…This is a more elegant way to handle spatial variation in detectability than our proposed centrality criterion, but requires full anatomic coverage for template registration, as well as the presence of multimodal input data. A potentially even more promising newer approach is the use of deep learning in the form of convolutional neural networks (CNNs), which are capable of incorporating data from tremendously large training sets to self‐learn complex pattern recognition algorithms in a manner similar to the way the human visual system works . CNNs have consistently topped recent general lesion segmentation challenges like those hosted by the Medical Image Computing and Computer Aided Intervention (MICCAI) society .…”

“…Previous studies focused primarily on brain diseases compared to diseases of the spinal cord because MRI has been successful in diagnosing brain‐related illness. In addition, spinal cord diseases exhibit more variations in their morphology and signals in sagittal MRI 12–15 . Only a few studies have investigated spinal cord diseases on MRI using CNN models.…”
