Abusive head trauma (AHT) is one of the most common subtypes of nonaccidental trauma and is a leading cause of traumatic brain injury in young children. Imaging plays a crucial role in the evaluation of children with suspected AHT and can aid in accurate diagnosis because clinical presentation may be nonspecific. In this article, the CNS injuries that are characteristic of AHT are reviewed with an emphasis on pathophysiology and imaging appearance. ⋯ AHT is a frequent cause of neurologic injury in children, particularly in infants in the first year of life. Imaging evaluation plays a vital role in determining the diagnosis and prognosis. A review of the intracranial injuries that are common in AHT cases has been provided. Understanding the common patterns of abusive head injury can help increase diagnostic accuracy both by increasing recognition of injuries with a high specificity for AHT and by avoiding unwarranted concern in patients with concordant injury patterns and clinical history.

Prostate Imaging Reporting and Data System, Version 2, Assessment Categories and Pathologic Outcomes in Patients With Gleason Score 3 + 4 = 7 Prostate Cancer Diagnosed at Biopsy.
The purpose of this study is to assess associations between Prostate Imaging Reporting and Data System, version 2 (PI-RADSv2), categories and the presence of a tumor with a Gleason score (GS) of 4 + 3 = 7 or greater or the presence of extraprostatic extension (EPE) at radical prostatectomy (RP) in patients with a GS 3 + 4 = 7 tumor at biopsy. ⋯ For GS 3 + 4 = 7 cancers detected at transrectal ultrasound-guided biopsy, higher PI-RADSv2 assessment categories are associated with upgrading to GS 4 + 3 = 7 cancer and with the presence of EPE after RP. A PI-RADSv2 score of 3 or higher was 100% sensitive for diagnosing GS 4 + 3 = 7 tumors.
