Added value of the final clinical-radiological model for patients with indeterminate/compatible radiological conclusions. (a) A 50-year-old woman presented at the emergency with chest pain, fever, and cough for less than one week. Chest CT showed a basal-predominant peripheral ground-glass opacity (GGO—white arrow) in the lower right lobe. The probability for RT-PCR + was 68.9%. (b) A 71-year-old woman presented at the emergency with cough, dyspnoea, fever and asthenia for 1–2 weeks. Chest CT showed bilateral peripheral fibrotic bands (white arrowheads) with a peripheral right GGO (white arrow). The probability for RT-PCR + was 65%. (c) A 61-year-old woman with a medical history of active smoking, emphysema and chronic obstructive pulmonary disease presented at the emergency with a cough, dyspnoea, fever and asthenia. Chest CT showed peripheral predominant intralobular reticulations in the lower left lobe (black arrowheads) with a single area of non-rounded GGO (white arrow). The probability for RT-PCR + was 57.9%. In the three cases, the RT-PCR was indeed positive.
