Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

MRICP method

Arm Description

MRI sequences have been developed that may be able to estimate ICP in a non-invasive fashion.6-10 The MRI-based method for measurement of ICP (MRICP method) is based on basic principles of the cranio-spinal CSF physiology: The mono-exponential relationship between intracranial volume and pressure leads to a linear relationship between elastance (i.e., the derivative of pressure with respect to volume) and pressure.

Outcomes

Primary Outcome Measures

Intracranial Pressure Measurements Estimated by the MRICP Technique.
The measurement of the momentary differences between the volumes of blood and CSF entering and leaving the cranium during the cardiac cycle provides an estimate of the intracranial volume change, and the pressure difference is estimated using the derivative of the CSF velocities.
Cerebro Spinal Fluid Pressure Measured by Lumbar Puncture
The CSF pressure measured at lumbar puncture (LP), is 100-180 mm of H2O (8-15 mm Hg) with the patient lying on the side and 200-300 mm with the patient sitting up.

Secondary Outcome Measures

Change in Intracranial Pressure Estimated With MR Technique
Description: assessment of change in estimated ICP prior to and following standard-of-care epidural patching; and (2) evaluate changes in diameter and flow velocity through the transverse dural venous sinus prior to and following epidural blood patching.
Change in Caliber to the Transverse Venous Sinus Caliber
Change in caliber to the Transverse Venous Sinus caliber has measured by non-contrast 3D phase contrast MR venography.
Change in Flow Velocity Through the Transverse Dural Venous Sinus
Description:Change in Flow velocity through the Transverse Dural venous sinus has measured by non-contrast 3D phase contrast MR venography

5. Study Description

Brief Summary
The purpose of this study is to estimate the intracranial pressure (ICP, the pressure in your head) in subjects with intracranial hypotension (a condition caused by leakage of the fluid that surrounds your brain and spine) using non-invasive magnetic resonance imaging (MRI) techniques, and to determine whether changes in estimated ICP are seen after treatment of this condition.
Detailed Description
Subjects with known intracranial hypotension who are scheduled to undergo standard-of-care CSF pressure measurement using lumbar puncture prior to planned epidural patch treatment will first undergo a research MRI of the brain in order to estimate ICP. The imaging protocol is listed in Appendix 1. All research scans are performed without intravenous contrast. Approximate scan time per session will be 20-22 minutes. Subjects will then undergo lumbar puncture according to the standard-of-care treatment plan. Estimated values of CSF pressure derived from MRI will be compared to values measured during lumbar puncture. Patients will then undergo standard-of-care epidural patching. A repeat research MRI after epidural patching will be performed to assess for differences in pre- and post-treatment scans.
