Imaging of the brainstem is technologically challenging due to its complex structure.
There are gray matter nuclei with vital functions near white matter tracts with very
important connections, such as the Cortico-Spinal Tract (CST). Further, the location
of the brainstem near bony structures and surrounded by vessels adds additional
MR imaging di;culties due to the lower homogeneity of the ;eld and
the ;ow e;ect of both the vessels and the cerebral spinal ;uid.
Structural imaging with 3D sequences, either in T1 or T2 weighting, has been a
major advance in assisting with the diagnosis of small lesions of the brainstem.
Advanced techniques such as spectroscopy, di;usion, and perfusion sequences
add important information that can reliably handle many lesions due to the high
risk of biopsy operations. Therefore, proper management of imaging techniques
is particularly important in lesions of the brainstem.1
