Posterior fossa emissary venous canal prevelance and visibility on standart computed tomography

The aim of this study is to investigate the emissary venous channel prevelance and the visibility of these emissary venous canals in the posterior cranial fossa on standard Computerized Tomography in patients without intracranial pathology. Unenhanced Standard Brain Computerized Tomography images of 79 patients (25 males, 54 females; mean age, 41 ± 11 years) with normal findings were evaluated retrospectively. Mastoid emissary venous canal and occipital emissary venous canal measurements and visibility were evaluated in these Computerized Tomography images. A p value of
