According to DECT,
47%,
30% and 23% of the exams showed low,
intermediate and high AILD probability respectively with high ICC among radiologists (r = .983) .
Based on the clinical assessments,
67%,
19% and 14% of patients had low intermediate and high AILD probability respectively,
with moderate ICC (r = .798) among pulmonologists.
ICC between DECT and clinical diagnoses was moderate (r = .608).

Out of the 83 examined patients: 2 patients had severe breathing artifacts and were excluded; 22(27%) patients had no parenchymal lung abnormalities,
17(21%) had air space opacities,
36(44%) had areas of atelectasis (including linear atelectasis) ,
33(41%) had ground glass opacities and 8(10%) had lung nodules (4-25 mm in size).
On the iodine sensitive images among the 17 patients with air space opacities 10,
2 and 5 patients had absent,
possible and definite iodine deposits respectively; among the 36 patients with areas of atelectasis 17,
7 and 12 patients had absent,
possible and definite iodine deposits respectively; among the 33 patients with ground glass opacities 18,
10 and 5 patients had absent,
possible and definite iodine deposits respectively; among the 8 patients with lung nodules 7 and 1 patients had absent and definite iodine deposits respectively.
Absent,
possible and definite iodine deposits were identified in the liver parenchyma of 42(52%),
23(28%),
16(20%) patients respectively.
