Disparities in 5-year outcomes and imaging surveillance following elective endovascular repair of abdominal aortic aneurysm by sex, race, and ethnicity.
The purpose of this study was to identify variations in 5-year outcomes and imaging surveillance after elective endovascular aortic aneurysm repair (EVAR) by sex, race, and ethnicity and to examine possible mechanisms contributing to these variations. The primary outcome was 5-year aneurysm rupture. Secondary outcomes were 5-year reintervention and mortality, and having no aortic imaging follow-up from 6 to 24 months after EVAR. The study found that among 16,040 patients, 73% were White males, 18% were White females, 2.6% were Black males, 1.1% were Black females, 0.9% were Asian males, 0.2% were Asian females, 1.7% were Hispanic males, and 0.4% were Hispanic females. At 5 years, Black females had the highest rupture rates at 6.4% and white males had the lowest at 2.3%. Compared with White males, rupture rates were higher in White females, Black females, and Asian females. Among other groups, Black males had higher reintervention and both Black and Hispanic males had higher rates of no imaging follow-up. In adjusted analyses, White, Black, and Asian females remained at significantly higher risk for 5-year rupture. The researchers concluded that Black females had higher 5-year aneurysm rupture, reintervention, and mortality rates after elective EVAR as compared with White male patients, whereas White females had higher rupture, mortality and loss-to-imaging-follow-up compared to White male patients. Black males had higher reintervention and no imaging follow-up, and Asian females had higher rupture rates.

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.

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.

Imaging as an outcome measure in gout studies: Report from the OMERACT Gout Working Group.
Discussion in the Outcome Measures in Rheumatology (OMERACT) working group was focused to consider (1) features of gout that should be recorded using imaging, (2) best methods of measuring these features, and (3) joints that should be imaged. The working group identified 3 relevant domains for imaging in gout studies: urate deposition (tophus burden), joint inflammation, and structural joint damage.

Association of early imaging for back pain with clinical outcomes in older adults.
This study compared function and pain at the 12-month follow-up visit among older adults who received early imaging with those who did not receive early imaging after a new primary care visit for back pain without radiculopathy. It found that early imaging was not associated with better 1-year outcomes. The researchers concluded that the value of early diagnostic imaging in older adults for back pain with radiculopathy is uncertain.

Comparative effectiveness of imaging modalities to determine metastatic breast cancer treatment response.
This literature review evaluates studies regarding the effectiveness of different imaging modalities in evaluating treatment response among metastatic breast cancer patients. The review of the literature demonstrates a current paucity of evidence regarding the use of imaging for treatment evaluation of metastatic lesions among breast cancer patients.

Safety of intravenous tissue plasminogen activator administration with computed tomography evidence of prior infarction.
The researchers sought to determine if the presence of a previous stroke on pretreatment computed tomography (CT) is a predictor of hemorrhagic complications and functional outcomes after the administration of intravenous (IV) tissue plasminogen activator (tPA). Their data suggest that a prior stroke on CT should not be viewed as a reason to withhold this treatment unless it occurred within the last 3 months.
