Next-wave model: predicting the shape, depth, and length of a subsequent wave of coronavirus disease 2019 (COVID-19) using the interplay between current radiology recovery and a phased reopening policy. By looking at how much volume is regained during each phase without resurgence of the virus, we can assume that policy would be rolled back to the most lenient but safe phase, having the same effect on imaging volume as during the corresponding phase of the first wave. With this model, in our case, we estimated that a second wave of COVID-19 would result in an overall yearly drop in imaging volume of about 1% to 3%, compared with the 10% to 15% total yearly drop that we predicted from the first wave.
