From: Computed tomography to estimate cardiac preload and extravascular lung water. A retrospective analysis in critically ill patients

  CT-based estimation of EVLWI vs. TPTD-derived EVLWI
EVLWI < 7 mL/kg EVLWI 7 - 10 mL/kg EVLWI > 10 mL/kg
Radiologist 1 Sensitivity 20 (0.5 to 72) 64 (31 to 89) 7 (0.1 to 34)
  Specificity 88 (69 to 97) 26 (9 to 51) 75 (48 to 93)
  PPV 25 (0.6 to 81) 33 (15 to 57) 20 (0.5 to 72)
  NPV 85 (65 to 96) 56 (21 to 86) 48 (28 to 69)
Radiologist 2 Sensitivity 20 (0.5 to 72) 64 (31 to 89) 29 (8 to 58)
  Specificity 88 (69 to 97) 37 (16 to 62) 81 (54 to 96)
  PPV 25 (0.6 to 81) 37 (16 to 62) 57 (18 to 90)
  NPV 85 (65 to 96) 64 (31 to 89) 57 (34 to 77)
  1. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) given as percentages with 95% confidence intervals (95% CI) in parentheses for computed tomography (CT)-based estimations of extravascular lung water index (EVLWI) with regard to EVLWI derived from transpulmonary thermodilution (TPTD) are shown separately for radiologist 1 and radiologist 2.
