CT of the bronchopulmonary veins in patients with superior vena cava or left brachiocephalic vein obstruction.
The purpose of this study was to show the arrangement and connections of the bronchopulmonary veins (i.e., vessels draining the bronchi, bronchioles, and pleura in patients with chronic superior vena cava (SVC) or left brachiocephalic vein (LBCV) obstruction using CT. ⋯ The arrangement and connections of the bronchopulmonary veins in patients with chronic SVC or LBCV obstruction can be depicted by CT; these vessels form an intricate network connecting the systemic and pulmonary venous circulations and can act as systemic-pulmonary shunts.

FDG volumetric parameters and survival outcomes after definitive chemoradiotherapy in patients with recurrent head and neck squamous cell carcinoma.
The purpose of this study was to establish the predictive value of (18)F-FDG parameters for overall survival in biopsy-proven recurrent head and neck squamous cell cancer (HNSCC) patients after definitive chemoradiotherapy. ⋯ FDG PET/CT-based total MTV and clinical HPV status may be significant prognostic markers for overall survival of patients with recurrent HNSCC after definitive chemoradiotherapy.

Radiologic features of injuries from the Boston Marathon bombing at three hospitals.
The aim of this study is to describe the radiologic imaging findings of primary, secondary, tertiary, and quaternary blast injuries in patients injured in the Boston Marathon bombing on April 15, 2013. ⋯ Injuries from the Boston Marathon bombing were predominantly from the secondary blast wave and resulted in traumatic injuries predominantly of the lower extremities. The most common shrapnel found on radiologic evaluation was the ball bearing.

Disparities in imaging utilization for acute ischemic stroke based on patient insurance status.
Previous studies have shown socioeconomic disparities in imaging utilization for both acute and chronic diseases. We studied a nationwide database to determine whether insurance-based disparities exist in the utilization of imaging for acute ischemic stroke. ⋯ Disparities exist in the utilization of noninvasive head and neck imaging, MRI, and echocardiography for patients with acute ischemic stroke based on patient insurance status. More research is needed to understand these disparities.
