All chest CT acquisitions were obtained by maintaining the patients in a supine position during end-inspiration, with or without contrast medium injection. Chest CT images were acquired using either a Dual Source 384-slice (2 × 192) CT (Siemens SOMATOM Force, Erlangen, Germany; tube real-time voltage modulation, 70–150 kV; tube real-time dose modulation (CARE Dose4D™), 80–250 mAs; spiral pitch factor, 1.8; collimation width, 0.6 mm), a 128-slice CT (Siemens SOMATOM Definition AS, Erlangen, Germany; tube voltage, 120 kV; tube real-time dose modulation (CARE Dose4D™), 80–250 mAs; spiral pitch factor, 1.2; collimation width, 0.6 mm) or a 40-slice CT (Philips Brilliance CT; tube voltage, 120 kV; 80–150 mAs; spiral pitch factor, 1.0; collimation width, 0.625 mm).
Every patient’s temperature was taken before entering the hospital, and dedicated paths were established for oncologic patients. Moreover, all patients and medical staff wore the proper personal protective equipment (PPE) during hospital stay and during CT scan acquisition, and a meticulous decontamination of the CT room and passive air exchange was carried out after every scan performed on patients with clinical or imaging suspicion of COVID-19.
