To assess the necessity of intravenous contrast medium for abdominopelvic computed tomography (CT) diagnosis of acute appendicitis (APP) among adult patients with right lower quadrant (RLQ) abdominal pain at emergency department (ED). ⋯ The diagnostic sensitivity of CCT was significantly better than that of NCT. Intravenous contrast administration could also make doctors easier in indentifying appendixes.

To assess the prognostic value of metabolic tumor burden as measured with metabolic tumor volume (MTV) and total lesion glycolysis (TLG) on 2-deoxy-2-((18)F)fluoro-D-glucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT), independent of current Union Internacional Contra la Cancrum/American Joint Committee on Cancer tumor, node, and metastasis (TNM) stage; in comparison with that of standardized uptake value (SUV) in surgical patients with non-small-cell lung cancer (NSCLC). ⋯ Baseline whole-body metabolic tumor burden as measured with MTV(WB) and TLG(WB) on FDG PET is a prognostic measure independent of clinical stage and other prognostic factors including chemoradiation therapy and surgical procedure with low interobserver variability and may be used to further risk stratify surgical patients with NSCLC. This study also suggests that MTV and TLG are better prognostic measures than SUV(max) and SUV(mean). These results will need to be validated in larger cohorts in a prospective study.

The Association of Program Directors in Radiology (APDR) conducts an annual survey to monitor and evaluate issues pertaining to radiology residents' educational experiences, work responsibilities, and benefits. Data are used to identify emerging trends and patterns of change to plan and provide resources that support radiology residency programs and their directors. ⋯ Data generated by the annual survey enable the APDR to accrue data pertaining to residents' real-time educational experiences. In 2011, program directors were satisfied with their jobs but not convinced that competency-based program requirements had positive effect on residency training. Programs plan to use the Radiological Society of North America and American Association of Physicists in Medicine Web-based physics training modules. Most radiology programs do not have residents-as-teachers programs, nor do they plan to initiate them. During recruitment, programs use an applicant's location as a proxy for true interest in the program, and interest in the program is important for granting interviews and final ranking. Qualified international medical graduate applicants have access to radiology training in the United States and Canada. Almost half of radiology programs have in-house reading by attending radiologists with residents on call. Residency programs have been slow to embrace social media.

Comparative Study
Three-dimensional airway tree architecture and pulmonary function.
The airway tree is a primary conductive structure, and airways' morphologic characteristics, or variations thereof, may have an impact on airflow, thereby affecting pulmonary function. The objective of this study was to investigate the correlation between airway tree architecture, as depicted on computed tomography, and pulmonary function. ⋯ Despite the large variability in anatomic characteristics of the airway tree across subjects, architecture-based measures demonstrated statistically significant associations (P < .01) with nearly all pulmonary function testing measures, as well as with disease severity.
