    Dear Editor

    We read with interest the letter by Dr Gupta on our paper entitled “A diffusion tensor magnetic resonance imaging study of brain tissue from patients with migraine”.[1] Nevertheless, we believe that he missed the main result of this study as well as the scope for which it was designed and conducted. The aim of this study was to investigate whether occult’ tissue damage, which goes undetected when usin...

    Diffusion tensor magnetic resonance imaging in migraine: clinical perspective.

    Dear Editor

    Rocca and colleagues, using diffusion tensor magnetic resonance imaging (DT-MRI) found white matter abnormalities in normal appearing brain tissue occult to conventional MRI.[1] As these authors underscore, the nature of such abnormalities remain obscure and are unlikely to ever be resolved by histopathological studies. The biological significance of these subtle white matter abnormalities, nevertheless, w...
