Background: The dural venous sinuses show different types of morphometric variations in their anatomy as well as involvement with various neurological conditions like cerebral venous sinus thrombosis, venous sinus stenosis, embolism, fistula etc. Cerebral MRV (Magnetic Resonance Venography) is a well-established radiological technique to visualize the dural venous system. By measuring the sinus dimensions in cerebral MRV images and calculating the indices, morphometric variations of the dural venous sinuses can be identified which is essential for diagnosing different pathologies of the dural venous system. Researcher have detected most of the variations in the superior sagittal, transverse and sigmoid venous sinuses. Objectives: To develop anatomical baseline data on morphometric measurements of the dural venous sinuses in normal cerebral MRV images of adult Bangladeshis. Methods: The research was cross-sectional and observational in nature. It was carried out in the Department of Anatomy, Bangabandhu Sheikh Mujib Medical University (BSMMU) in collaboration with the Department of Neuroradiology & Imaging, National Institute of Neuroscience and Hospital (NINS), Dhaka, from March 2020 to June 2021. Adults (35 males and 35 females) aged 18 years or above who attended in the Department of Neuroradiology & Imaging, NINS for cerebral MRV and diagnosed as having normal dural venous sinuses without any pathology by a registered Neuroradiologist were the participants of this research. The MRV scans were produced by using 3 Tesla magnetic field strength following the routine standard protocols of the institution. By using the Radiant DICOM Viewer software, a total of 9 linear and curvilinear dimensions were measured and 2 indices were calculated by the researcher and the co-investigator independently to reach consensus on each variable. Results: A numerical data set was generated on the morphometric measurements of the superior sagittal, transverse and sigmoid sinuses ......
