Nine patients with suspected elevated intracranial pressure and 9 healthy control patients were included in this prospective study. Control patients underwent DENSE MR imaging through the midsagittal brain while patients underwent DENSE MR imaging followed immediately by lumbar puncture with opening pressure measurement, CSF removal, closing pressure measurement, and immediate repeat DENSE MR imaging. All patients had elevated opening pressure (median, 36.0 cm water), decreased by the removal of CSF to a median closing pressure of 17.0 cm water. Measured CSF pressure in patients pre= and post=lumbar puncture correlated significantly with pontine displacement. The authors conclude that DENSE MR imaging may providing a method to noninvasively assess intracranial pressure status in idiopathic intracranial hypertension.

Twenty patients with deep lumbosacral spinal dural arteriovenous fistulas were included in this series. Cord T2 hyperintensity and contrast enhancement were present in most cases. The filum vein and/or lumbar veins were dilated in 95% of patients. Time-resolved contrast-enhanced dynamic MRA indicated a spinal DAVF at or below the L5 vertebral level in 7/8 (88%) patients who received time-resolved contrast-enhanced dynamic MRA before DSA. A bilateral arterial supply of the fistula was detected via DSA in 5 (25%) patients. The authors conclude that time-resolved contrast-enhanced dynamic MRA facilitates the detection of the drainage vein and helps to localize deep lumbosacral-located fistulas with a high sensitivity before DSA. Definite detection remains challenging and requires conventional spinal angiography.
