Our results suggest that epilepsy surgery outcomes of MRI-negative, PET positive patients are similar to those of patients with MTS. This finding may aid in the selection of best candidates for epilepsy surgery.

Marchiafava-Bignami disease (MBD) is characterized by demyelination and necrosis of corpus callosum encountered in chronic alcoholic patients. Etiology is the deficiency of vitamin B complex. Magnetic resonance imaging (MRI) in MBD typically reveals focal lesions of high T2 and FLAIR signal intensity in the corpus callosum. We here present a 42-year-old male alcoholic diagnosed as MBD on the basis of MRI and diffusion-weighted imaging (DWI) features. The patient totally recovered following appropriate vitamin B complex replacement therapy, despite reduced diffusion in the initial setting. This case report emphasizes on the important role played by MRI and DWI in the early diagnosis and follow-up of this potentially fatal disease.

An internal coil design method that takes advantage of the UISNR and optimum coil sensitivity calculations was presented. This method can also be used to design better internal MRI coils for different applications.
