Diagnostic Imaging

Computed tomography (CT) of the head is generally the first diagnostic tool to evaluate patients with suspected neurological pathology, even though it lacks the sensitivity and specificity needed to evaluate changes associated with venous sinus thrombosis (Buccino et al., 2003; Chow et al., 2000; Ekseth et al., 1998; Frey et al., 1999; Patel et al., 2004; Soleau et al.). CT venogram (CTV) is useful at identifying changes within the venous system, if available. Magnetic resonance imaging (MRI) is more sensitive and specific to the changes seen with venous sinus thrombosis. The magnetic resonance venogram (MRV) is the diagnostic tool of choice (Buccino et al., 2001; Buccino et al., 2003; Ekseth et al.; Frey et al.; Patel et al.). Cerebral angiography is generally not performed unless MRI and MRV are unavailable, or the patient is unable to have a magnetic resonance scan. Cerebral angiography is the only diagnostic tool that can evaluate the patency of cortical veins (Buccino et al., 2001; Ekseth et al., 1998; Patel et al.).
