Adding MBI to DBT finds more breast cancers
By Amerigo Allegretto
Adding molecular breast imaging (MBI) to DBT screening leads to more invasive cancers detected in women with dense breasts.
September 23, 2025
Images in a 62-year-old woman who presented for screening. (A) Image from DBT screening (the synthesized 2D mediolateral oblique view of the left breast is shown) at year on was interpreted as negative and showing heterogeneously dense breast. (B) Image from molecular breast imaging screening (mediolateral oblique view) at year one reveals a 0.9-cm non-mass focal area of uptake in the left breast (arrow). (C) Targeted ultrasound scan (transverse image) shows a suspicious mass in the 3-o’clock position of the left breast, 4 cm from the nipple. Ultrasound-guided core biopsy and lumpectomy revealed a 0.9-cm grade 2 invasive ductal carcinoma, an estrogen receptor–negative, progesterone receptor–negative, human epidermal growth factor receptor 2–negative lesion, with two sentinel nodes negative (N0).

An example of a typical BgRT plan: A) PET scan on diagnostic PET/CT and B) X1 PET-Linac for patient #15 with a PET avid rib metastasis with GTV size= 3.1 cc, PTV = GTV + 5mm, BTZ (biological tracking zone) = PTV + 5 mm, AC = 14.33 kBq/mL and NTS = 21.04. Red, magenta, and green contours represent GTV, PTV, and BTZ. C) Dose distribution and D) bounded-DVH of a BgRT plan are displayed for the same patient. The bounded Dose-Volume Histogram (DVH) models variations in BgRT delivery, encompassing fluctuation in target background signal variation, target localization and dose delivery uncertainties.
