Spectral CT
Truth in beauty and beauty in layers...


Complex kidney cyst

Hyperdense lesion in right kidney is indeterminate on routine CT.

Spectral analysis shows it is hyperdense on virtual non-contrast, and has no iodine content (on iodine map and fused image), consistent with hemorrhagic cyst.

Impression is confirmed with MRI (T2W, T1W and post-contrast subtraction image shown here).
