  1. Note: Data are given as number of examinations. Numbers in parentheses are percentages.
  2. aThere was a significant difference between noncontrasted MRI and contrasted MRI by Yates-corrected chi-square test (p < 0.001).
  3. bPossible malignancy, probable malignancy, and indeterminate small nodule are considered to be suspicious lung nodules.
