Sports-related peripheral nerve injuries are common among athletes and are often underrecognized because of symptom overlap with more usual sports-related bone, soft-tissue, and joint injuries. ⋯ MRI plays an increasingly important role in the workup of peripheral nerve injuries and may reveal severe nerve abnormalities before they are diagnosed by electrodiagnostic testing or a clinical examination. Sport-specific peripheral nerve injuries and their MRI appearance will be discussed in this article.

Randomized Controlled TrialTransverse sinus stenosis in adult patients with Chiari malformation type I.
Transverse sinus stenosis is an imaging finding very highly associated with elevated intracranial pressure (ICP). Patients with the Chiari I malformation may potentially have elevated ICP due to impairment of CSF flow at the foramen magnum. This study evaluated whether patients with Chiari I malformation have transverse sinus stenosis and other imaging findings indicative of elevated ICP. ⋯ Patients with Chiari I malformation have higher likelihood of transverse sinus stenosis, which may reflect associated elevated ICP.

ReviewFractures of the distal radius: postmanagement radiographic characterization.
The purpose of this article is to describe the management options available for the treatment of the distal radius fracture as well as potential associated complications. ⋯ There are a wide variety of currently accepted and used treatment options for fractures of the distal radius, ranging from closed reduction with casting to various forms of invasive surgical management. The radiologist must be familiar with these various forms of management to recognize complications when present on follow-up radiographs.

Randomized Controlled TrialChronic respiratory symptoms associated with airway wall thickening measured by thin-slice low-dose CT.
In lung cancer screening, the prevalence of chronic respiratory symptoms is high among heavy smokers. The purpose of this study was to compare CT-derived airway wall measurements between male smokers with and those without chronic respiratory symptoms. ⋯ Male heavy smokers with chronic respiratory symptoms in lung cancer screening, who are at high-risk of chronic bronchitis, have bronchial wall thickening in airways with a luminal diameter of 5-10 mm but not in larger airways.

Prognostic value of FDG PET metabolic tumor volume in human papillomavirus-positive stage III and IV oropharyngeal squamous cell carcinoma.
The purpose of this study was to establish the prognostic utility in human papillomavirus (HPV)-positive stage III and IV oropharyngeal squamous cell carcinoma (SCC) of the (18)F-FDG parameters maximal, mean, and peak standardized uptake value (SUVmax, SUVmean, and SUVpeak, respectively); metabolic tumor volume (MTV); and total lesion glycolysis (TLG). ⋯ Total MTV and primary-tumor MTV are associated with survival outcomes in patients with HPV-positive stage III and IV oropharyngeal SCC.
