| Abstract:

Traditionally computed tomography is the initial investigation for many intracranial pathology including suspicion of
cerebral venous sinus thrombosis. non pathological causes of increase in the cerebral venous sinuses density can
mimic venous sinuses thrombosis that should taken into account before preceding for further imaging modalities
.The study aimsto find the correlation between the cerebral venous sinuses density with the hemoglobin level and
the packed cell percentage using non-enhanced computed tomography to ovoid overestimating a normally hyper
dense sinuses as thromboses one ,furthermore not underestimating the is dense thromboses sinuses in patient
with anemia as normal density sinus.Dural sinus density on NECT is closely related to Hb and PCV% levels.
Therefore, Hb or PCV levels can be used to determine whether the Dural sinus density is within the normal range
or abnormal {a regression equation can be used to estimate the HU from the Hb such as (HU=2.28Hb +25.8) or
from the PCV% such as (HU=0.52 PCV+33.6)}.Quantitative assessment of the Dural sinuses is easy and less timeconsuming
work
in
clinical
practice
without
additional
radiation
exposure,
therefore,
when
grossly
hypo
dense
or
hyper
dense
Dural
sinuses
are
observed
on
NECT,
so
Dural
sinus
attenuation
have
to
be
measured
and
correlate
with
the
Hb
or
PCV
levels.
