Table 1. Lesion-to-background ratios for each malignancy.

Malignancy	Mean DWI signal intensity lesion-to-background ratio (range)	Mean STIR signal intensity lesion-to-background ratio (range)	p-value
Prostate	3.91 (1.29–7.25)	2.31 (1.52–3.42)	0.0001
Breast	4.13 (1.99–9.86)	4.26 (2.10–13)	0.8587
Myeloma	7.59 (2.67–14.7)	3.70 (1.15–5.7)	0.0366

DWI, diffusion-weighted MRI; STIR, short-tau inversion recovery.
