Lumbar spinal stenosis severity by CT or MRI does not predict response to epidural corticosteroid versus lidocaine injections.
This study compared the results of patients with lumbar spinal stenosis injected epidurally with corticosteroids and lidocaine, or lidocaine alone. A prospective, double-blind study was conducted on 350 patients who were then evaluated for qualitative or quantitative MR imaging or CT measures of lumbar spinal stenosis. There were no differences in improvement of disability or leg pain scores at 3 weeks between the two subgroups.

Study of Tomography Of Nephrolithiasis Evaluation (STONE): methodology, approach and rationale.
This paper describes the rationale and methods of STONE (Study of Tomography Of Nephrolithiasis Evaluation), a pragmatic randomized comparative effectiveness trial comparing different imaging strategies for patients with suspected urolithiasis. It concluded that the detailed methodology of STONE will provide a roadmap for comparative effectiveness studies of diagnostic imaging conducted in an ED setting.
