title: Calculation of the liquor system pliability using the mathematical simulation method.
abstract: Liquor circulation is a directed flow of the liquor from sites of its secretion to sites of resorption. This slow flow is modulated by pulsation caused by heart work. Phase-contrast magnetic resonance imaging is a method for noninvasive measurements of the linear velocity of these pulses in the cerebral aqueduct. A mathematical model reproducing pulsed flow of the liquor in the cerebral aqueduct is proposed and the procedure of evaluation of these parameters is presented. The pliability liquor system can be calculated from the values of liquor flow linear velocity in the cerebral aqueduct, measured by noninvasive method.
