Healthcare identification technology developer PDC Healthcare has introduced a new line of Spee-D-Mark skin markers designed for use with digital breast tomosynthesis (DBT) exams.
The 3D DBT skin markers help technologists and radiologists mark and identify moles, scars, palpable masses, and areas of concern with minimal "slinky" artifact on DBT studies, according to the vendor. The new markers join the firm's current Spee-D-Mark skin markers for traditional mammography exams, which have been sold since 1995 under the St. John Companies brand, PDC said.











![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
