The elastance index for intracranial pressure estimation: A cine phase-contrast MR study with a fluid dynamics model
نویسندگان
چکیده
' X Abstract We investigated an intracranial pressure (ICP) estimation method based on aqueductal cerebrospinal fluid (CSF) flow rate measurements from cine phase-contrast MR images. A fluid dynamics model is provided that relates CSF flow rate change to the elastance index, which is a parameter proportional to the ICP. Experimental results from 8 patients with clinical diagnosis of increased ICP showed significantly larger elastance index than 9 healthy adults (867.38k492.25 vs. 397.67+160.35, P=0.016). MR-based noninvasive ICP estimation may be a potentially useful tool in the assessment of clinical idiopathic intracranial hypertension.

Non-invasive measurement of intracranial compliance using cine MRI in normal pressure hydrocephalus.
The aim of this study is to clarify biophysics of normal pressure hydrocephalus (NPH) based on non-invasive intracranial compliance measurement using magnetic resonance imaging (MRI). Patients with NPH after subarachnoid hemorrhage (NPH group, n = 5), brain atrophy or asymptomatic ventricular dilation (VD group, n = 5), and healthy volunteers (control group, n = 12) were included in this study....
متن کاملMRI Evidence for Altered Venous Drainage and Intracranial Compliance in Mild Traumatic Brain Injury
PURPOSE To compare venous drainage patterns and associated intracranial hydrodynamics between subjects who experienced mild traumatic brain injury (mTBI) and age- and gender-matched controls. METHODS Thirty adult subjects (15 with mTBI and 15 age- and gender-matched controls) were investigated using a 3T MR scanner. Time since trauma was 0.5 to 29 years (mean 11.4 years). A 2D-time-of-flight ...
متن کاملevaluation of communication between intracranial arachnoid cysts and cisterns with phase-contrast cine MR imaging.
BACKGROUND AND PURPOSE The demonstration of communication between arachnoid cysts (ACs) and the adjacent subarachnoid space is a prerequisite for their proper management. CT cisternography (CTC) is the conventional method for functional evaluation of ACs. The sensitivity of MR imaging to CSF flow has been demonstrated, but reports of the clinical usefulness of MR CSF flow techniques in this app...
متن کاملElucidating the pathophysiology of syringomyelia.
OBJECT Syringomyelia causes progressive myelopathy. Most patients with syringomyelia have a Chiari I malformation of the cerebellar tonsils. Determination of the pathophysiological mechanisms underlying the progression of syringomyelia associated with the Chiari I malformation should improve strategies to halt progression of myelopathy. METHODS The authors prospectively studied 20 adult patie...

The NPH group could be further divided into hyperand hypodynamic groups when compared with the normal agematched subjects. Vmax of the control group was significantly higher than that of the hypodynamic-NPH group (1.92 ± 1.11 cm/s, p < 0.001) and lower than that of the CH group (p < 0.007) and of the hyperdynamicNPH group (10.52 ± 0.23 cm/s, p < 0.001). With optimized parametric setting, two-di...
