Chest CT in "Post" COVID-19: What the Radiologist Must Know.

Recent orthopedic surgical literature emphasizes a three-column approach to understand and guide the treatment of tibial plateau fractures. This three-column classification system published in 2010 relies on preoperative CT images to depict injuries to the medial, lateral, and posterior columns of the tibial plateau and improves surgical outcomes in complex tibial plateau fractures with coronal fracture planes and posterior plateau fracture fragments requiring dorsal plating. Tibial plateau fracture classification systems traditionally used by radiologists and orthopedic surgeons, including the Schatzker and the Arbeitsgemeinschaft für Osteosynthesefragen-Orthopedic Trauma Association (AO-OTA) classification systems, rely on findings at anteroposterior radiography and lack the terminology to accurately characterize fractures in the coronal plane involving the posterior tibial plateau. ⋯ Additional information provided by preoperative cross-sectional imaging, including two-dimensional and three-dimensional CT and MRI in specific circumstances, aids in the identification of specific soft-tissue injuries and fracture morphologies that influence surgical management. These specific fracture morphologies and soft-tissue injuries should be identified and communicated to orthopedic surgeons for optimal patient management.

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) results in coronavirus disease 2019 (COVID-19), which was declared an official pandemic by the World Health Organization on March 11, 2020. The infection has been reported in most countries around the world. As of August 2020, there have been over 21 million cases of COVID-19 reported worldwide, with over 800 000 COVID-19-associated deaths. ⋯ Part 2 will focus on key imaging features of COVID-19 that involve the cardiac, neurologic, abdominal, dermatologic and ocular, and musculoskeletal systems, as well as pediatric and pregnancy-related manifestations of the virus. Vascular complications pertinent to each system will be also be discussed in part 2. Online supplemental material is available for this article. ©RSNA, 2020.
