Practice Guideline
Factors associated with radiologists' adherence to Fleischner Society guidelines for management of pulmonary nodules.
In 2005, the Fleischner Society guidelines (FSG) for managing pulmonary nodules detected on CT scans were published. The aim of this study was to evaluate adherence to the FSG, adjusting for demographic and clinical variables that may contribute to adherence. ⋯ Pulmonary nodules are prevalent findings on chest and abdominal CT scans. Although most radiologists recommend follow-up imaging for these findings, recommendations for pulmonary nodules were consistent with the FSG in 34% of radiology reports. Nodule size demonstrated an association with guideline adherence, after adjusting for key variables.

An increasing portion of imaging studies are performed by nonradiologists, especially for modalities with the highest relative value units. The aim of this study was to examine the trends in neuroradiologic interpretation among radiologists, neurologists, neurosurgeons, and other specialists within the Medicare population. ⋯ There was marked growth (140%) in neuroradiologic studies between 1996 and 2010 in the Medicare patient population. Radiologists' share of the total neuroradiologic interpretations remained unchanged and constituted 93.5% in 2010. Radiology's market share has shown growth in the inpatient and hospital outpatient sectors but not the private office sector, where independent diagnostic testing facilities, multidisciplinary groups, and other specialists have seen increases.

The aim of this study was to assess the association of patient encounter complexity and the utilization of CT of the abdomen and pelvis (CTAP) in the emergency department (ED) setting. ⋯ Of patients undergoing CTAP in the ED setting, a very large majority (93.8%) are clinically complex. CT of the abdomen and pelvis is 5.95 times more likely to be utilized in higher than lower complexity ED patient encounters.
