This study investigated whether paraspinal muscle wasting occurs in association with chronic low back pain (LBP). Cross-sectional areas (CSA) of spinal and paraspinal structures were measured radiographically, at the level of L4, in 43 patients with recent and 44 with chronic LBP. Crude anthropometry demonstrated no differences between the groups with(More)
Arachnoid cysts are a common incidental finding on routine brain imaging and, for the most part, their presence is uneventful. Occasionally they may be associated with haemorrhage into the subdural compartment. Rarer still is simple rupture of the contents of the arachnoid cyst into the extra-axial space. MRI can help distinguish between these two rare(More)
Epidural abscess of the cervical spine is an uncommon disorder. The presentation is often non-specific and the diagnosis unsuspected. Magnetic resonance (MR) imaging is now considered the imaging investigation of choice. We report six patients with cervical epidural abscess diagnosed on MR imaging. The MR imaging showed the abscess to have a variable(More)
Eleven patients have been examined by whole body CT employing the EMI CT 5000 following lumbar injection of 10 ml of metrizamide (Amipaque) 170 mg I/ml. The distribution, flow and dilution of the contrast medium have been investigated. The results suggest that whilst metrizamide is necessary in the spinal canal to demonstrate the neural axis and pathologic(More)
