New Spinal CSF Leak Imaging Factsheet

Imaging Quick Reference Factsheet FB Advert 1

Quick Reference Guide to Spinal CSF Leak Imaging Techniques

We we delighted to have been able to release our brand new factsheet on imaging techniques to coincide with both Day Three of Leak Week UK and global Rare Disease Day 2018.

The guidance provides a brief overview to most of the common imaging techniques that diagnosed or suspected spinal CSF leak sufferers will encounter on their diagnostic and treatment journeys.

It was prepared with significant professional input and should answer many of the common questions that patients have about the different scans that they’re put forward for.

New CSF Leak Journal Articles

Standard

We’ve added three additional journal articles to our downloads section.

Two articles about the use of gadolinium in CSF Leak detection:

One review paper by Dr Wouter Schievink of Cedars-Sinai Hospital, California:

Role of MR Myelography with Intrathecal Gadolinium in Localization of Spinal CSF Leaks

Standard

 

mri-gadolinium-contrastA, Pre- and post-intrathecal gadolinium fat-suppressed T1 images demonstrate typical artifacts, which may simulate a leak at C1-C2 seen in 6 of 41 of our patients. Note the inhomogeneous fat saturation on this precontrast sagittal T1 image at C1-2 (arrow). B, Recognizing this artifact on precontrast imaging is important because with the addition of intrathecal gadolinium, this inhomogeneous fat saturation can potentially mimic a leak (arrow).

Schematic drawing of 4-point-scale grading system of CSF leak on MRM (A) and RIC (B). A, Our grading scale on MRM is depicted as follows: grade zero, no leak (normal findings on MR myelogram); grade 1, possible leak (expansion of the CSF space column around the nerve root sleeve); grade 2, probable leak (streaky hyperintensity lateral to the nerve root sleeves but with length less than the transverse diameter of the thecal sac); and grade 3, definite leak (lateral extension greater than the transverse diameter of the thecal sac). However, actual grading of the case is determined on the basis of the highest grade in each level of the spine. B, Grade of CSF leak on RIC is depicted as follows: grade zero, no paraspinal activity; grade 1, possible leak (faint paraspinal activity with length under the transverse diameter of spinal canal activity); grade 2, probable leak (hot paraspinal activity with the length under the transverse diameter of spinal canal activity); and grade 3, definite leak (hot paraspinal activity with the length over the transverse diameter of spinal canal activity)‏
