A Novel Frameshift Mutation in Two Siblings with Merosin-deficient Congenital Muscular Dystrophy

Haseki Tıp Bülteni, 2020
We present two siblings with elevated serum creatine kinase concentrations, developmental delay, muscle weakness, and contractures of the lower limbs. Cranial magnetic resonance imaging revealed diffuse white matter hyperintensity in both siblings.

White matter hyperintensities in subjects with bipolar disorder [PDF]

Psychiatry and Clinical Neurosciences, 2004
Abstract  There have been divergent reports on the prevalence and severity of white matter hyperintensities (WMH) on brain magnetic resonance (MR) images in subjects with bipolar disorder. In the present study, evaluations were made on the prevalence and severity of WMH in subjects with bipolar disorder using contiguous 3‐mm thick MR slices as well as ...

Semisupervised white matter hyperintensities segmentation on MRI

Human Brain Mapping, 2022
AbstractThis study proposed a semisupervised loss function named level‐set loss (LSLoss) for cerebral white matter hyperintensities (WMHs) segmentation on fluid‐attenuated inversion recovery images. The training procedure did not require manually labeled WMH masks.

Ensemble learning via supervision augmentation for white matter hyperintensity segmentation

Frontiers in Neuroscience, 2022
Since the ambiguous boundary of the lesion and inter-observer variability, white matter hyperintensity segmentation annotations are inherently noisy and uncertain. On the other hand, the high capacity of deep neural networks (DNN) enables them to overfit

The Evolution of White Matter Hyperintensities

US Neurology, 2010
White matter hyperintensities (WMHs) are a common finding on magnetic resonance imaging (MRI) scans of elderly subjects. Despite their frequency, the clinical correlates and etiology of WMH remain controversial, with many conflicting results published. This is due, in part, to the varied populations studied. Nevertheless, the prevailing opinion is that
