Molecular breast images in the mediolateral oblique projection from a 41-year-old patient with a palpable lesion that was suspicious on diagnostic mammography and scheduled for biopsy (Table 2, benign lesion #16). At blinded review, MBI performed with 300 MBq ^99mTc sestamibi (a) was interpreted as having a focal area of moderate intensity radiotracer uptake with maximum extent of 1.3 cm. An assessment of 4 was assigned. MBI performed the same day with 740 MBq ^99mTc maraciclatide (b) was also interpreted as assessment 4 with lesion extent measuring 1.6 cm. Biopsy revealed necrotizing granulomatous inflammation and fibrosis
