Journal ArticleDOI
Evidence for widespread axonal damage at the earliest clinical stage of multiple sclerosis.
Massimo Filippi,Marco Bozzali,Marco Rovaris,Oded Gonen,Chandrasekharan Kesavadas,Angelo Ghezzi,Vittorio Martinelli,Robert I. Grossman,G. Scotti,G. Comi,Andrea Falini +10 more
TL;DR: Widespread axonal pathology, largely independent of MRI-visible inflammation and too extensive to be completely reversible, occurs in patients even at the earliest clinical stage of multiple sclerosis, and argues strongly in favour of early neuroprotective intervention.
Journal ArticleDOI
Resting state fMRI: A review on methods in resting state connectivity analysis and resting state networks.
K A Smitha,K Akhil Raja,K M Arun,P.G. Rajesh,Bejoy Thomas,T R Kapilamoorthy,Chandrasekharan Kesavadas +6 more
TL;DR: The concept of resting state functional magnetic resonance imaging is introduced in detail, three most widely used methods for analysis are discussed, and a few of the resting state networks featuring the brain regions, associated cognitive functions and clinical applications are described.
Journal ArticleDOI
Clinical applications of susceptibility weighted MR imaging of the brain - a pictorial review
Bejoy Thomas,Sivaraman Somasundaram,Krishnamoorthy Thamburaj,Chandrasekharan Kesavadas,Arun Kumar Gupta,Narendra Bodhey,Tirur Raman Kapilamoorthy +6 more
TL;DR: This unique MR sequence will help in detecting occult low flow vascular lesions, calcification and cerebral microbleed in various pathologic conditions and aids in characterizing tumors and degenerative diseases of the brain.
Journal ArticleDOI
Susceptibility weighted imaging: a new tool in magnetic resonance imaging of stroke
K. Santhosh,Chandrasekharan Kesavadas,Bejoy Thomas,Arjun Gupta,Krishnamoorthy Thamburaj,T. Raman Kapilamoorthy +5 more
TL;DR: This MR technique detects early haemorrhagic transformation within an infarct and provides insight into the cerebral haemodynamics following stroke, and helps in the diagnosis of cerebral venous thrombosis.
Journal ArticleDOI
Seizure outcome after anterior temporal lobectomy and its predictors in patients with apparent temporal lobe epilepsy and normal MRI.
TL;DR: Very little reliable information is available regarding the role of anterior temporal lobectomy (ATL), optimal presurgical evaluation strategy, post‐ATL seizure outcome, and the factors that predict the outcome in patients with medically refractory temporal lobe epilepsy and normal high‐resolution magnetic resonance imaging (MRI).
