A 59-year-old female with surgically removed meningioma.

<p>A lesion of mixed signal intensity (arrows) is seen in the posterior fossa on a T2-FLAIR image of the head (A) and a coronal whole-body T2-STIR image (B). A supplementary, preoperative contrast-enhanced MR study (C) demonstrated enhancing lesion with a tail sign (arrow).</p

A 77-year-old woman with 2.8 mm pulmonary nodule (arrow) in the left upper lobe (lingula).

<p>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).</p

The sensitivity of MRI for the detection of different subgroups of pulmonary nodules (according to the Fleischner Society nodule size category).

A 71-year-old man with 11.3 mm pulmonary nodule in the right lower lobe (arrow).

<p>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).</p
