Screening performance of digital breast tomosynthesis vs digital mammography in community practice by patient age, screening round, and breast density.
The purpose of this study was to compare digital mammography (DM) vs digital breast tomosynthesis (DBT) performance by age, baseline vs subsequent screening round, and breast density category. Information was taken from screening examinations at participating Breast Cancer Surveillance Consortium facilities of 1.5 million women aged 40 to 79 with no prior history of breast cancer. Findings showed that improvements in recall and cancer detection rates with DBT were greatest on baseline mammograms. On subsequent screening mammograms, the benefits of DBT varied by age and breast density, and women with extremely dense breasts did not benefit from improved recall or cancer detection with DBT on subsequent screening rounds.

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).
