An AI deep learning algorithm for detecting pulmonary nodules on ultra-low-dose CT in an emergency setting
The OPTIMACT trial investigated the added value of ultra-low-dose CT (ULDCT) compared to chest x-ray in patients suspected of pulmonary disease at the emergency department (ED). As expected, more incidental pulmonary nodules required follow-up in the ULDCT-arm (4.5%) compared to the CXR-arm (0.6%) of the trial. The number of these nodules in the ULDCT-arm was lower than reported in other
