Spinal stenosis - Diagnosis

Imaging Studies:Lateral radiograph of the spine bends is the most useful imaging method. Spondylolisthesis bone hypertrophy appears as curved edges on the girls side and rear side corpus. Hypertrophied articular girls are best seen in oblique diversion when the reading and lumbar and cervical neuroforamic space collapse. Interrupting the psoas muscle may indicate a paravertebral abscess or tumor.
Computed tomography evaluates spinal stenosis with the smallest diameter. Scanning neck can be relieved by using intravenous contrast agents to enhance the epidural veins and epidural spaces to better define the edges. Enhancing epidural fibrosis is highest immediately after surgery. Paraspinale masses or calcifications may appear cystic or fluid in cases of abscess collections. In all cases, will determine the relationship between the mass and the central spinal canal, lateral and neuroforamen.
Magentic resonance shows osteophytes and calcified disk structures, an epidural soft tissue masses. After intravenous administration of contrast, inflammatory changes, tumors extraaxiale, stress reactions of the vertebral body shows signs of increased abstraction.
Scanning scintigraphy showed areas of increased activity associated with vertebral body plates, joints and joints uncovertebrale girls. Medical conditions associated with bone diseases: Paget's disease shows crescta capture the radionuclide. Metastatic disease are associated with increased intake in the abnormal bone.
Myelography documenting stenosis and remains high in the evaluation of lumbar disc herniation. Procedure complications include spinal headache, seizures, allergic reaction and nausea.
Electrodiagnosticul include electromyography, nerve conduction and somatosensory evoked potentials, all having assessed fucntia nerve roots and peripheral nerves. They detect radiculopathy, plexopatia lombposacrata, peripheral neuropathy and mononeuropatia.
The differential diagnosis is made with the following conditions: acondroplazia, osteogenezis imperfecta, rheumatoid arthritis, spondilodischita, osteoporosis, Paget's disease, prostate and breast cancer metastasis.
