Parameters of the applied MRI sequences.
Fig 1.
A 77-year-old woman with 2.8 mm pulmonary nodule (arrow) in the left upper lobe (lingula).
The nodule is well depicted on MDCT image (A), however it was not identified on corresponding MR images: T1 VIBE (B), T1 out-of-phase (C), T2 TSE (D), T2 HASTE (E), T2 SPIR (F), T2 STIR (G).
Fig 2.
A 62-year-old man with 5.6 mm pulmonary nodule in the right lower lobe (arrow).
The lesion is seen on CT (A) as well as on T1 VIBE (B), T1 out-of-phase (C) and T2 SPIR (F) images, whereas T2 TSE (D), T2 HASTE (E) and T2 STIR (G) images were negative.
Fig 3.
A 71-year-old woman with 7 mm pulmonary nodule in the right upper lobe (arrow).
The nodule is demonstrated on CT (A) and on most of T2-weighted sequences, including: T2 TSE (D), T2 SPIR (F) and T2 STIR (G). The readers did not identify this lesion on T1 VIBE (B), T1 out-of-phase (C) and T2 HASTE (E) images.
Fig 4.
A 71-year-old man with 11.3 mm pulmonary nodule in the right lower lobe (arrow).
The nodule is well visualized on CT (A) as well as on all MR images: T1 VIBE (B), T1 out-of-phase (C), T2 TSE (D), T2 HASTE (E), T2 SPIR (F), T2 STIR (G).
