Key points. 1. CT is used to confirm the diagnosis of acute pancreatitis when the diagnosis is in doubt and to differentiate acute interstitial pancreatitis from necrotizing pancreatitis, which is a key element of the updated Atlanta nomenclature. The acute interstitial variety accounts for 90-95% of cases, with acute necrotizing pancreatitis accounting for the remaining cases. 2. ⋯ Mild acute pancreatitis has neither acute complications nor organ failure. Moderate-severity acute pancreatitis is associated with acute complications or organ failure lasting fewer than 48 hours. Severe acute pancreatitis is characterized by single- or multiorgan failure persisting for greater than 48 hours.

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.
