    • Brain MRI Lesion Load at 1.5T and 3T versus Clinical Status in Multiple Sclerosis 

      Stankiewicz, James; Glanz, Bonnie; Healy, Brian Curran; Arora, Ashish; Neema, Mohit; Benedict, Ralph H.B.; Guss, Zachary D.; Tauhid, Shahamat Syed; Buckle, Guy J.; Houtchens, Maria K.; Khoury, Samia Joseph; Weiner, Howard Lee; Guttmann, Charles R.G.; Bakshi, Rohit (Wiley-Blackwell, 2011)
      Background/Purpose: To assess correlation between brain lesions and clinical status with 1.5T and 3T magnetic resonance imaging (MRI). Methods: Brain MRI fluid-attenuated inversion-recovery (FLAIR) sequences were performed ...

    • The Impact of Lesion In-Painting and Registration Methods on Voxel-Based Morphometry in Detecting Regional Cerebral Gray Matter Atrophy in Multiple Sclerosis 

      Ceccarelli, A.; Jackson, J. S.; Tauhid, S.; Arora, A; Gorky, J.; Dell, E.; Bakshi, A.; Chitnis, Tanuja; Khoury, Samia Joseph; Weiner, Howard Lee; Guttmann, Charles R.G.; Bakshi, Rohit; Neema, Mohit (American Society of Neuroradiology (ASNR), 2012)
      Background and Purpose: VBM has been widely used to study GM atrophy in MS. MS lesions lead to segmentation and registration errors that may affect the reliability of VBM results. Improved segmentation and registration ...

    • Normal Findings on Brain Fluid-Attenuated Inversion Recovery MR Images at 3T 

      Neema, M; Guss, Z.D.; Stankiewicz, James; Arora, A; Healy, Brian Curran; Bakshi, Rohit (American Society of Neuroradiology (ASNR), 2009)
      Background and Purpose: Fluid attenuated inversion recovery (FLAIR) MR imaging of the brain has become a routine tool for assessing lesions in patients with suspected neurologic disorders. There is growing interest in 3T ...

    • Quantification of Global Cerebral Atrophy in Multiple Sclerosis from 3T MRI Using SPM: The Role of Misclassification Errors 

      Dell’Oglio, Elisa; Ceccarelli, Antonia; Glanz, Bonnie I; Healy, Brian C; Tauhid, Shahamat; Arora, Ashish; Saravanan, Nikila; Bruha, Matthew J; Vartanian, Alexander V; Dupuy, Sheena L; Benedict, Ralph HB; Bakshi, Rohit; Neema, Mohit (BlackWell Publishing Ltd, 2014)
      Purpose We tested the validity of a freely available segmentation pipeline to measure compartmental brain volumes from 3T MRI in patients with multiple sclerosis (MS). Our primary focus was methodological to explore the ...
