From: Can the abbreviated MRI protocol replace the standard full protocol in the detection and characterization of breast non-mass enhancement?

Thirty-year-old woman referred with right unresolved mastitis (problem-solving indication). a Precontrast T1WI showed diffuse skin thickening and edema, no masses. b First post-contrast subtraction showed diffuse heterogeneous non-mass enhancement with enhancement of the skin (arrow heads) and retromammary muscle (arrow). Contralateral breast showed segmental heterogeneous non-mass enhancement; these findings could be seen in 1st MIP (c). d T2WI showed no masses. e Late post-contrast subtraction confirmed pectoralis muscle invasion (arrow); contralateral non-mass enhancement showed type II kinetic curve. (f) The two lesions showed restricted signal in DWI (b-value 800 s/mm2) (g) with ADC values = 1.1 × 10−3 mm2/s for the right breast lesion (h) and 1.3 × 10−3 mm2/s for the left one (i). The right breast lesion interpreted as BIRADS V, while the left lesion interpreted as BIRADS IV in both protocols. True cut needle biopsy of right breast revealed invasive carcinoma, while left breast lesion revealed DCIS
