## Brain MRI Report
 
MR imaging of the brain was performed on a 1.5 T MR scanner using head coil.  T1 FLAIR, FSE T2, GRE T2*-- Axial, FSE T2-- sagittal and T2 FLAIR coronal images were acquired.  The study was supplemented with diffusion weighted images using EPI sequence.  Post contrast SE T1 weighted images were also obtained in coronal, sagittal and axial planes.

The study reveals multiple discrete foci of T2 / FLAIR hyperintensity in left frontal, left parietal, periventricular and centrum semiovale region and bilateral posterior parietal periventricular white matter region and pericallosal interface.

Post contrast images reveals subtle enhancing lesions in the left periventricular white matter region, left pericallosal region, left frontal and posterior periventricular white matter region.

Rest of the cerebral parenchyma shows normal signal characteristics.  Myelination pattern of the brain is normal. No evidence of restricted diffusion noted.

/*
Serialization is the process of converting a data structure or object into a sequence of bits so that it can be stored in a file or memory buffer, or
transmitted across a network connection link to be reconstructed later in the same or another computer environment.
Design an algorithm to serialize and deserialize a binary tree. There is no restriction on how your serialization/deserialization
algorithm should work. You just need to ensure that a binary tree can be serialized to a string and this string can be deserialized to the original tree structure.
For example, you may serialize the following tree
    1
   / \
  2   -3
     /
