The validity of upright myelography for diagnosing lumbar disc herniation.
Although computed tomographic (CT) myelography and magnetic resonance imaging (MRI) are used for assessing lumbar disc herniations (LDH), they cannot provide images when patients are standing or walking, whose CT myelograms and MRI images show only slight disc bulging. The purpose of this study was to evaluate the usefulness of upright myelography. We examined by myelography in both an upright ...
متن کاملThe Lumbar Spine as a Dynamic Structure Depicted in Upright MRI
Spinal canal stenosis is a dynamic phenomenon that becomes apparent during spinal loading. Current diagnostic procedures have considerable short comings in diagnosing the disease to full extend, as they are performed in supine situation. Upright MRI imaging might overcome this diagnostic gap.This study investigated the lumbar neuroforamenal diameter, spinal canal diameter, vertebral body transl...
متن کاملUpright positional MRI of the lumbar spine.
Supine magnetic resonance imaging (MRI) is routinely used in the assessment of low back pain and radiculopathy. However, imaging findings often correlate poorly with clinical findings. This is partly related to the positional dependence of spinal stenosis, which reflects dynamic changes in soft-tissue structures (ligaments, disc, dural sac, epidural fat, and nerve roots). Upright MRI in the fle...
متن کاملUpright MRI in kinematic assessment of the ACL-deficient knee.
The ability to quantify in vivo femoro-tibial relations in the knee holds great advantage to further patient care. There is little consensus on the optimal weight-bearing environment and measurement method for MRI assessment of in vivo knee kinematics. This study set out to establish the optimal method of measuring femoro-tibial relations in an upright, weight-bearing environment in normal indi...
متن کاملUpright, Weight-bearing, Dynamic-kinetic Mri of the Spine: Pmri/kmri
The purpose of the study was to demonstrate the general utility of the first dedicated magnetic resonance imaging (MRI) unit enabling upright, weight-bearing positional evaluation of the spinal column (pMRI) during various dynamic-kinetic maneuvers (kMRI) in patients with degenerative conditions of the spine. This study consisted of a prospective analysis of cervical or lumbar imaging examinati...
