Dear AuntMinnie Member,
A new study published today in the New England Journal of Medicine could mean good news for coronary CT angiography by highlighting the low diagnostic yield of catheter-based angio studies, according to an article we're featuring in our Cardiac Imaging Digital Community.
U.S. researchers found that nearly two-thirds of patients referred to cardiac cath ended up with no signs of obstructive coronary disease, indicating that a high number of patients are being unnecessarily exposed to an invasive test with a low diagnostic yield.
The results hint that the current diagnostic workup for patients with suspected coronary artery disease isn't working. Indeed, an editorial in the same issue points to the potential of CT angiography as an imaging test that could be a better "gatekeeper" for angiography.

Another SGR fix passes
In other news, the U.S. Senate yesterday passed what could be a more long-term solution to the sustainable growth rate (SGR) problem, which is requiring a 21% cut in Medicare reimbursement to physicians.
The Senate passed a bill that would delay the SGR cuts until October, presumably giving Congress more time to implement a longer-term fix. If the current bill doesn't pass the House of Representatives, then the SGR cuts will go into effect April 1.

![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&dpr=2&fit=crop&h=167&q=70&w=250)
