■ Superior Longitudinal Fasciculus
■ Inferior Longitudinal Fasciculus
■ Uncinate Fasciculus
■ Arcuate Fasciculus
■ Inferior Occipitofrontal Fasciculus
, Mini Case Study
A 37 year old patient presents complaining of
difficulties speaking. After initial testing you deduce
that they have intact auditory comprehension,
coherent (yet paraphasic) speech production, but
. You order an MRI scan with
poor speech repetition
DTI to confirm your diagnosis.
