Gov. Chris Sununu of New Hampshire has signed a bill that requires insurers to cover digital breast tomosynthesis (DBT), the American College of Radiology (ACR) reported.
SB 189 amends the state's legal definition of low-dose mammography to include DBT. It will go into effect on August 7.
New Hampshire is the 15th state to pass mandatory DBT coverage laws, joining Arkansas, Connecticut, Illinois, Kentucky, Louisiana, Maryland, Missouri, New Jersey, New York, Oklahoma, Pennsylvania, Texas, Vermont, and the state of Washington, the ACR 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)
