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.

Rationale and design of the Randomized Evaluation of patients with Stable angina Comparing Utilization of noninvasive Examinations (RESCUE) trial.
This article describes the RESCUE trial, which is based on the hypothesis that coronary computed tomography angiography as a diagnostic tool is associated with no increase in cardiac risk, decreased cost, and reduced radiation exposure compared with single photon emission computed tomography myocardial perfusion imaging.

Comparative effect of contrast media type on the incidence of contrast-induced nephropathy: a systematic review and meta-analysis.
This review compared contrast-induced nephropathy (CIN) risk for contrast media within and between osmolality classes in patients receiving diagnostic or therapeutic imaging procedures. No differences were found in CIN risk among types of low-osmolar contrast media (LOCM). Iodixanol had a slightly lower risk for CIN than LOCM, but the lower risk did not exceed a criterion for clinical importance.

Diagnostic performance of cardiac magnetic resonance imaging and echocardiography in evaluation of cardiac and paracardiac masses.
The researchers evaluated the predictive value of echocardiography and cardiac magnetic resonance (CMR) imaging parameters to identify tumors and malignancy and to provide histopathologic diagnosis of cardiac masses. They found that CMR identified 6 masses missed on transthoracic echocardiography (4 of which were outside the heart) and provided significantly more correct histopathologic diagnoses compared to echocardiography (77 percent vs 43 percent).

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.
