Successful visualization of dynamic change of lumbar nerve root compression with the patient in both upright and prone positions using dynamic digital tomosynthesis-radiculography in patients with lumbar foraminal stenosis: An initial report of three cases

摘要

The symptoms of lumbar foraminal stenosis are often exacerbated when the patient is upright. Lumbar pathological conditions related to clinical symptoms such as disc herniation, foraminal stenosis, and instability of the lumbar spine are often exacerbated when the patient is upright and hidden when the patient is supine. Lumbar radiculopathy is usually diagnosed by MRI. However, it is difficult to detect the compression of nerve roots while the patient is upright using conventional MRI when the patient is supine. Dynamic digital tomosynthesis radiculography (DTRG) while the patient is upright detects pathological changes of the lumbar nerve root while the patient is upright.
