BACKGROUND AND PURPOSE: Recently, Lee et al reported a new grading system for the
lumbar spinal foraminal stenosis. They considered the type of stenosis, the amount of fat …

OBJECTIVE. This study aimed to evaluate the reproducibility of a new grading system for
lumbar foraminal stenosis. MATERIALS AND METHODS. Four grades were developed for …

Objective Magnetic resonance imaging (MRI) grading systems using sagittal images are
useful for evaluation of lumbar foraminal stenosis. We evaluated whether such a grading …

Purpose The preoperative identification of lumbar foraminal stenosis (LSFS) is important
because a lack of recognition of this clinical entity is often associated with failed back …

Objectives Part 1: To assess the reliability of a semiquantitative classification system for
grading lumbar spine foraminal stenosis and the variability in magnetic resonance imaging …

Study Design. Retrospective case series with a control group. Objective. To measure the
diagnostic performance of magnetic resonance imaging (MRI) and MR myelography (MRM) …

In this paper we sought to develop and assess the reproducibility of an updated 6-point
grading system for lumbar foraminal stenosis based on the widely used Lee classification …

Purpose No clinical CT-based classification system is currently in use for lumbar foraminal
stenosis. MRI scanners are not easily available, are expensive and may be contraindicated …

Purpose To determine the static and dynamic radiological findings characteristic of
symptomatic foraminal stenosis. Methods Between 2006 and 2011, a total of 114 patients …

Lumbar foraminal stenosis is a common cause of lumbar radiculopathy and conventionally
assessed with magnetic resonance imaging (MRI) in supine-positioned patients. An MRI …
