Variation among primary care physicians in the use of imaging for older patients with acute low back pain.
The authors sought to estimate the variation among primary care providers (PCPs) in the use of diagnostic imaging for older patients with non-specific acute low back pain. They used Texas Medicare claims data and tracked whether each patient received lumbar imaging within 4 weeks of the initial visit. They found that the specific physician seen by a patient accounted for 25 % of the variability in whether imaging was performed and that the use of imaging by individual physicians was stable over time.

Yield of emergent neuroimaging in children with new-onset seizure and status epilepticus.
The purpose of this paper was to determine the yield of emergent neuroimaging among children with new-onset seizures presenting with status epilepticus. The authors found that a substantial minority of children with new-onset seizures presenting with status epilepticus have urgent or emergent intracranial pathology identified on neuroimaging and that magnetic resonance imaging is the preferred imaging modality when available and safe.

The evaluation of distal symmetric polyneuropathy: utilisation and expenditures by community neurologists.
The aim of the study was to determine utilization and expenditures in the evaluation of a new diagnosis of distal symmetric polyneuropathy (DSP) by community neurologists using a population-based design and a strict case definition. It concluded that electrodiagnostic tests and MRIs are frequently ordered in the diagnostic evaluation of DSP and account for more than 80% of the expenditures.

Appropriateness of cardiac stress test use among primary care physicians and cardiologists in the United States.
In this study, the researchers used nationally-representative data to examine differences in appropriate use of cardiac stress testing between cardiologists and primary care physicians (PCPs) in the US. Using permissive criteria to determine appropriateness, they found that primary care physicians are more likely to order or perform a rarely appropriate cardiac stress test than cardiologists.

Computed tomography screening for lung cancer: A high-value proposition?
This study assessed the cost-effectiveness of low-dose computed tomographic scan screening for lung cancer within the Canadian health care system. It found that compared with no screening, the reference scenario saved 51,000 quality-adjusted life-years (QALY) and had an incremental cost-effectiveness ratio of CaD $52,000/QALY.

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).
