Abstract
Background/Aims:In the present study, dural venous sinuses and
cerebral veins were examined using 3D SPGR MRV and 2D TOF MRV. These methods
were compared in terms of detectability of venous structures and their
diameters.
Methods:A total of 110 patients(66 female and 44 male) who
had contrast-enhanced 3D SPGR MRV and 2D TOF MRV examinations using a 1.5 T MRI
machine in May 2008-June 2011 period were included in the present study.
Diameters of dural venous sinuses and veins were measured at three different
planes at a position 1cm distal to the site they drained into, and average
values were used. Both MRV methods were compared to reveal whether the
diameters calculated were different in age groups and between genders.
Results:SSS, bilateral TS’s, right sigmoid sinus, Galen
vein and bilateral ICV’s all could be determined using 3D SPGR MRV. Not all
dural venous sinuses and veins other than right sigmoid sinus could be
visualized in all patients using 2D TOF MRV.There were significant differences
between the two examinations for SSS and ISS, bilateral TS and sigmoid sinuses,
SS, bilateral Labbe and ICV and Galen vein diameters(p<0.05) Diameters of
dural venous sinuses and cortical veins were generally measured larger by 3D
SPGR MRV compared to 2D TOF MRV.
Conclusions:In conclusion,
differences could be observed between the two MRV examinations for
detectability and diameters of intracranial venous structures. Evaluation of
intracranial venous structures should not be carried out using only 2D TOF MRV.
