Summary: Purpose: Very little reliable information is available regarding the role of anterior temporal lobectomy (ATL), optimal presurgical evaluation strategy, post‐ATL seizure outcome, and factors that predict outcome in patients with medically refractory lobe epilepsy (TLE) normal high‐resolution magnetic resonance imaging (MRI). To be cost‐effective, surgery centers developing countries will have to select candidates for by using locally technology expertise. Methods: We reviewed...

<h3>Aims</h3> To assess the functional and clinical outcome in a sizeable cohort of patients with osmotic demyelination syndrome (ODS) to characterise factors which could predict final outcome. <h3>Methods</h3> Twenty five consecutive ODS formed study cohort. The diagnosis was based on features corroborating imaging findings. Two scales—Functional Independent Measure (FIM) Disability Rating Scale (DRS)—were applied status at time admission, discharge last follow-up. Patients who became...

Abstract Three-dimensional (3D) constructive interference in steady state (CISS) is a gradient-echo MRI sequence that used to investigate wide range of pathologies when routine sequences do not provide the desired anatomic information. The increased sensitivity 3D CISS an outcome accentuation T2 values between cerebrospinal fluid (CSF) and pathological structures. Apart from its well-recognized applications evaluation cranial nerves, CSF rhinorrhea aqueduct stenosis, we have found be useful...

The work explores the use of denoising autoencoders (DAEs) for brain lesion detection, segmentation, and false-positive reduction. Stacked (SDAEs) were pretrained using a large number unlabeled patient volumes fine-tuned with patches drawn from limited patients (n=20, 40, 65). results show negligible loss in performance even when SDAE was 20 labeled patients. Low grade glioma (LGG) segmentation achieved transfer learning approach which network high data LGG image patches. networks also shown...

Context With the advent of new imaging modalities, radiologists are faced with handling increasing volumes data for diagnosis and treatment planning. The use automated intelligent systems is becoming essential in such a scenario. Machine learning, branch artificial intelligence, increasingly being used medical image analysis applications as segmentation, registration computer-aided detection. Histopathological currently gold standard classification brain tumors. machine learning algorithms...

In this work, we have focused on the segmentation of Focal Cortical Dysplasia (FCD) regions from MRI images. FCD is a congenital malformation brain development that considered as most common causative intractable epilepsy in adults and children. To our knowledge, latest work concerning automatic was proposed using fully convolutional neural network (FCN) model based UNet. While there no doubt outperformed conventional image processing techniques by considerable margin, it suffers several...

Background:The contribution of cerebral small vessel disease to cognitive decline, especially in non-Caucasian populations, is not well established. Objective:We examined the relationship between and motoric risk syndrome (MCR), a recently described pre-demen tia syndrome, Indian seniors. Methods:139 participants (mean age 66.6 ± 5.4 y, 33.1% female) participating Kerala-Einstein study Southern India were cross-sectional study.

Object Vein of Galen malformations (VGMs) are extremely rare intracranial lesions. Clinical presentation and management strategies vary significantly in different areas the world. The authors report their experience evaluation, management, long-term follow up these lesions India. Methods Between October 1983 June 2003, 25 patients with VGMs were referred to authors’ institution for evaluation management. Ten children younger than 2 years age presented rapidly increasing head size as chief...

Hyperglycemia-induced hemichorea can show T1 hyperintensity of the contralateral striatum on MRI. This is thought to be due petechial hemorrhages or gemistocytic astrocyte accumulation. study explores utility susceptibility-weighted imaging (SWI) and diffusion-weighted (DWI) in identifying nature these lesions. Three patients underwent MR brain with SE T1, F T2, DWI, SWI. images showed predominantly involving striatum, where mild (two cases) moderate (one case) restricted diffusion (low...

Summary Purpose In contrast to the well‐recognized association between acute symptomatic seizures and neurocysticercosis, antiepileptic drug ( AED )–resistant epilepsy calcified neurocysticercosis lesions CNL s) is poorly understood. We studied ‐resistant s, including feasibility outcome of resective surgery. Methods From prospective database maintained at our center, we reviewed data all patients with who underwent presurgical evaluation from January 2001 July 2010 had on imaging. used...
