Non-invasive MR intracranial pressure measurement (MR-ICP) has limited clinical applicability due to measurement errors, a great portion of which likely comes from internal jugular vein (IJV) pulsations. Experiments on normal volunteers were conducted to evaluate how the IJV flow patterns on various measurement positions affect the peak-to-peak intracranical volume changes (ICVC), which then used to estimate the MR-ICP. Results showed strong correlations between ICVC and IJV pulsatility indexes, both increasing as slices caudally shifted, quite apparently caused by right atrial hemodynamics. With properly positioned IJV measurement, the accuracy and reliability of MR-ICP measurement can be effectively improved.
