The greatest failure in medicine is to leave a patient undiagnosed, for without understanding, there can be no relief.

Overdiagnosis is more than a clinical challenge, it’s a societal one. In this episode of the AJR Podcast Series on Diagnostic Excellence and Error, @francisdeng.medsky.social and Saurabh Jha, MD‬ explore where clinical vigilance meets ethical complexity.

Bad news: CTA head and CTA neck will be bundled into one CPT code starting in 2026, which portends a reimbursement cut (it was ~25% when CT abdomen+pelvis were bundled in 2011).

Good news: CT perfusion will have its own category I CPT code separate from CTA head, which may improve reimbursement.

Radiology in #ERAS2026 is changing to separate signals for integrated IR/DR (8 signals) and DR programs (6 gold and 9 silver signals).

I’d advise applicants looking to maximize their chances of matching to apply to both.

In radiology, uncertainty is part of the job—but how it is communicated matters. In the latest episode of the AJR Podcast Series on Diagnostic Excellence and Error, @francisdeng.medsky.social and Atul B. Shinagare, MD discuss the unintended consequences of hedging.

CT utilization is 30% higher today than in 2007 due to growth of low-value ordering. At this rate, CT-induced cancers is modeled to account for 5% of new cancers in the coming decades. jamanetwork.com/journals/jam...

"No government — regardless of which party is in power — should dictate what private universities can teach, whom they can admit and hire, and which areas of study and inquiry they can pursue"

Harvard is standing up against the Trump administration www.nytimes.com/2025/04/14/u...

Harvard Will Not Comply With a List of Trump Administration Demands

Federal officials said Harvard must enact “merit-based reform” in hiring and admissions and report international students who broke rules, among other steps. Harvard called the demands unlawful.

"Of all imaging, 4% to 26% is estimated as inappropriate..."
huge waste and environmental impact!
www.jacr.org/article/S154... @katehanneman.bsky.social

Excess Greenhouse Gas Emissions Associated With Inappropriate Medical Imaging in the US Medicare Part B Population From 2017 to 2021

Medical imaging is a source of greenhouse gas emissions, and inappropriate use results in low-value, excess imaging. The environmental impact of low-value imaging has not been quantified.

Why do clinicians hate your radiology report?

1) No conclusion
2) Over-hedges
3) Misses the relevant finding

At #AAR25 keynote, Desiree Morgan advises us in times of change to keep in view your ‘horizon point’ - who/what you want to be in the future, eg, “an influential radiologist” and what that means
