Purpose: The purpose of this study was to retrospectively evaluate the quantitative and qualitative intra-patient concordance of pulmonary nodule risk assessment by commercially available radiomics software between full-dose (FD) chest-CT and ultra-low-dose (ULD) chest CT.Materials and methods: Between July 2013 and September 2015, 68 patients (52 men and 16 women; mean age, 65.5 +/- 10.6 [SD] years; range: 35-87 years) with lung nodules >= 5 mm and < 30 mm who underwent the same day FD chest CT (helical acquisition; 120 kV; automated tube current modulation) and ULD chest CT (helical acquisition; 135 kV; 10 mA fixed) were retrospectively included. Each nodule on each acquisition was assessed by a commercial radiomics software providing a similarity malignancy index (mSI), classifying it as "benign-like" (mSI < 0.1); "malignant-like" (mSI > 0.9) or "undetermined" (0.1
