title: Superior sagittal sinus blood flow in the dog measured by an electromagnetic flow meter. A comparison with a radioactive gas elimination method.
abstract: A simple method for continuous measurement of superior sagittal sinus blood flow (SSBF) in dogs, using an electromagnetic flow meter around the intact vessel, is presented. This method is compared with a procedure measuring radioactive gas elimination upon intra-arterial indicator injection. A good correlation between the cerebral blood flow (CBF), calculated from the fast component of the elimination curve and SSBF (r = 0.96) was found within a CBF range of 50-200 ml/100 g min.
