Comparative effectiveness of surveillance colonoscopy intervals on colorectal cancer outcomes in a national cohort of patients with inflammatory bowel disease.
The purpose of this study was to determine the comparative effectiveness of varying colonoscopy intervals on colorectal cancer (CRC) outcomes among patients with inflammatory bowel disease (IBD). Data was from the National Veterans Health Administration. Findings showed that, in a national cohort of patients with CRC-IBD, colonoscopy within 3 years prior to CRC diagnosis was associated with early tumor stage at diagnosis, and colonoscopy within 1 year was associated with a reduced all-cause mortality compared with no colonoscopy, supporting colonoscopy intervals of 1 to 3 years in patients with IBD in order to reduce late-stage CRC and all-cause mortality.

Accuracy of biomarker testing for neuropathologically defined Alzheimer disease in older adults with dementia
This study is a systematic review of biomarker and test accuracy for identification of Alzheimer Disease (AD) in older adults. Studies with low or medium risk of bias were analyzed, and two reviewers rated risk of bias. Fifteen brain imaging studies and 9 cerebrospinal fluid (CSF) studies met analysis criteria and were included. The meta-analysis found that in methodologically heterogeneous studies of uncertain applicability to typical clinical settings, the biomarkers amyloid PET, 18F-FDG proton emission tomography (PET), and magnetic resonance imaging (MRI) were highly sensitive for neuropathologic AD. Single studies suggested that adding amyloid PET, 18F-FDG PET, and CSF test combinations may add accuracy to clinical evaluation.

Patient stakeholder versus physician preferences regarding amyloid PET testing.
Patient and caregiver perspectives on amyloid positron emission tomography (PET) use are largely unexplored, particularly as compared with clinician views. In this study, the investigators surveyed clinicians, patients, caregivers, and dementia advocates on topics relating to an evidence-based guideline on amyloid PET use. They found that patients and caregivers emphasized the importance of having a dementia diagnosis and placed more value on testing and outcomes for asymptomatic populations than clinicians.

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.

Population-based assessment of the association between magnetic resonance imaging background parenchymal enhancement and future primary breast cancer risk.
The purpose of this study was to evaluate comparative associations of breast magnetic resonance imaging (MRI) background parenchymal enhancement (BPE) and mammographic breast density with subsequent breast cancer risk. The investigators concluded that BPE was associated with future invasive breast cancer risk independent of breast density. They suggest that BPE should be considered for risk prediction models for women undergoing breast MRI.

Diagnostic and prognostic value of myocardial blood flow quantification as non-invasive indicator of cardiac allograft vasculopathy.
Cardiac allograft vasculopathy (CAV) is a leading cause of death in orthotopic heart transplant (OHT) survivors. Effective non-invasive screening methods are needed. The aim of this study was to investigate the added diagnostic and prognostic value of myocardial blood flow (MBF) to standard myocardial perfusion imaging (MPI) with positron emission tomography (PET) for CAV detection.

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.

Optimizing patient-centered communication and multidisciplinary care coordination in emergency diagnostic imaging: a research agenda.
This article summarizes findings reached during the patient-centered outcomes session of the 2015 Academic Emergency Medicine consensus conference "Diagnostic Imaging in the Emergency Department: A Research Agenda to Optimize Utilization." The primary objective was to develop a research agenda focused on 1) defining component parts of the emergency diagnostic imaging care coordination process, 2) identifying gaps in communication that affect emergency diagnostic imaging, and 3) defining optimal methods of communication.

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.

Lumbar Imaging with Reporting of Epidemiology (LIRE)--protocol for a pragmatic cluster randomized trial.
The researchers will conduct a pragmatic cluster randomized clinical trial to test the hypothesis that inserting data on the prevalence of incidental imaging findings into lumbar spine imaging reports for studies ordered by primary care providers will reduce subsequent spine-related interventions. Their primary outcome will be spine-related intervention intensity based on Relative Value Units (RVUs) during the following year.
