Journal ArticleDOI
Wilson’s disease: cranial MRI observations and clinical correlation
Sanjib Sinha,Arun B Taly,S. Ravishankar,L.K. Prashanth,K. S. Venugopal,G. R. Arunodaya,M. K. Vasudev,H. S. Swamy +7 more
TL;DR: MRI changes were universal but diverse and involved almost all the structures of the brain in symptomatic patients and provided an explanation for the protean manifestations of Wilson’s disease.
Journal ArticleDOI
Diffusion-weighted imaging and proton MR spectroscopy in the characterization of acute disseminated encephalomyelitis
K. S. Balasubramanya,Jerry M.E. Kovoor,Peruvumba N. Jayakumar,S. Ravishankar,Ravindra Kamble,Jalesh N. Panicker,Dindagur Nagaraja +6 more
TL;DR: ADEM lesions were characterized in the acute stage by restricted diffusion and in the subacute stage by free diffusion and a decrease in NAA/Cho ratios, which may help in staging the disease.
Journal ArticleDOI
Electroencephalographic and imaging profile in a subacute sclerosing panencephalitis (SSPE) cohort: A correlative study
S. Praveen-kumar,Sanjib Sinha,Arun B Taly,S. Jayasree,Vasanthapuram Ravi,Joy Vijayan,S. Ravishankar +6 more
TL;DR: Irrespective of the incidence of occurrence of SSPE in a community, a clinician should be aware of the wide spectra of EEG findings and provide valuable insight into the structural and clinical correlates of EEG changes in S SPE.
Journal ArticleDOI
Gray matter volume deficits in spinocerebellar ataxia: An optimized voxel based morphometric study
Gaurav Goel,Pramod Kumar Pal,S. Ravishankar,Ganesan Venkatasubramanian,Peruvumba N. Jayakumar,N. Krishna,Meera Purushottam,Jitender Saini,Mohammed Faruq,Mitali Mukherji,Sanjeev Jain +10 more
TL;DR: This study showed that the different subtypes of SCAs may have morphometric differences in the cerebellum, brainstem and the supratentorial structures.
Journal ArticleDOI
Intrathecal gadolinium-enhanced magnetic resonance cisternography in cerebrospinal fluid rhinorrhea: road ahead?
Gaurav Goel,S. Ravishankar,Peruvumba N. Jayakumar,M.K. Vasudev,J.J. Shivshankar,Dawn Rose,B. Anandh +6 more
TL;DR: GdMRC is a novel method of confirmation and localization of CSF fistula with potential for routine clinical application due to its high-contrast resolution, absence of bony artifacts, and direct multi-planar imaging.
