Comparing the rates of low-value back images ordered by physicians and nurse practitioners for Medicare beneficiaries in primary care.
This study measures the rates of low-value back images ordered by primary care physicians and nurse practitioners for Medicare beneficiaries, and there was no detectable difference between the two groups in 2012 and 2013.

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.

Trimming the fat in acute ischemic stroke: an assessment of 24-h CT scans in tPA patients.
The authors questioned the utility of routine 24-h computed tomography imaging and looked at the National Institutes of Health Stroke Scale as a possible clinical screen for selecting candidates for 24-h imaging. They found that routine 24-h computed tomography scan in patients without 24-h National Institutes of Health Stroke Scale worsening was less likely to yield information that results in a deviation from standard acute stroke care, and that no patient without worsening had parenchymal hematoma on 24-h computed tomography. They concluded that application of this Stroke Scale to distinguish patients who should have 24-h follow-up imaging from those who will not benefit is a potential avenue for improving utilization of resources and warrants further study.
