Could not be more excited to match at my #1 @JeffersonRads !!!

Presented at #SIR26TOR: Among patients with moderate or severe PTS, the addition of endovascular therapy to standard care resulted in less severe PTS and better quality of life at 6 months than standard care alone but with a higher risk of bleeding.

This week, the "AI replacing doctors" debate is back. The CEO of America's largest public hospital system says he's ready to replace radiologists with AI. The Stanford-Harvard NOHARM study shows top models outperforming generalists. The discourse is moving fast. I run AI at @UHN, the largest hospital in Canada. Here's what I actually see. We've developed AI models across imaging, pathology, and clinical decision support. In controlled conditions, the accuracy numbers are real. In some narrow tasks, models genuinely outperform. That's not hype. But the operational reality of running these systems inside a large hospital teaches you things benchmarks never will. The errors that hurt patients aren't the confident wrong answers. They're the quiet omissions, i.e., the thing the model didn't flag because it wasn't in the training distribution. NOHARM found 76.6% of AI errors were omissions. We see this too. And in a hospital, a missed finding doesn't just affect one case. It propagates: the downstream physician trusts the AI read, the patient waits, the window closes. The accountability structure also doesn't exist yet. When an AI-assisted diagnosis leads to harm, who is responsible: the physician, the hospital, the vendor? In Canada, we don't have a clear answer. No hospital system deploying AI at scale does. That's not a regulatory delay. That's a fundamental gap in the infrastructure for AI-in-medicine. What I'm genuinely optimistic about: AI is already changing how our radiologists work. Not replacing them, but changing the shape of the job. Routine reads get faster. Their time shifts toward complex cases, clinical correlation, cases where the AI flags uncertainty. That's the right direction. But "ready to replace radiologists" skips 10 hard years of work on deployment infrastructure, liability frameworks, clinician training, and failure mode monitoring that nobody wants to talk about because it's less exciting than accuracy benchmarks. The capability question is nearly answered. The deployment question has barely been asked. CEO story: beckershospitalreview.com/radiology/nyc-… NOHARM paper: arxiv.org/abs/2512.01241

Congrats and welcome to our incoming diagnostic radiology residents!!!!! We can’t wait to welcome you to the reading room 🩻#matchday #matchday2026 #radiology

It doesn't get more golden than that! MEGAN KELLER WITH THE GAME-WINNING GOAL in OT! 🥇 #WeAreBC 🦅

Got some great reps in this morning with the @Mentice pulmonary thrombectomy simulator. A realistic feel that highlights the technical subtleties of a live case. Awesome simulation learning. Shoutout to @InariMedical for arranging ! #AnotherLifeSaved @JeffCVIR

CRUNCH-TIME MASTERCLASS FROM VJ EDGECOMBE! Middy. Triple. Putback slam. Hustle play. The #3 pick showing veteran poise 😮‍💨

I like it, Picasso.

REBOA = higher mortality (47% vs 36%), more transfusions, longer time to OR. No survival benefit. Check the new study by Hatchimonji et al. bit.ly/441iuXH and Jansen's commentary bit.ly/48a2TYi. @jhatchmd @dianehaddadmd @pdowzicky @markseamonmd

Retrievable IVC filters are increasingly used, but their characteristics are often inconsistently documented in radiology reports. Improved standardization could enhance follow-up, retrieval, and patient safety. cvirendovasc.springeropen.com/articles/10.11… @KeckMedicineUSC @UWRadiology @cvirendo

VJ Edgecombe is the first guard in NBA history to average 25/5/5 through 3 career games.

Finally got a chance to donate blood !! Love the shirt @TJUHospital

@CHICKVIR @BrendanCarneyDO @cirsesociety @KeckMedicineUSC @iRadRock @_backtable @CVIR_Journal @cvirendo @VenousNews @t_intheleadcoat @NDiazLorenzo @RajWellnessMD @mabadsantos Would stenting therefore be an option for primary axillosubclavian thrombosis i.e. thoracic outlet syndrome and Paget-Schroetter ? And would stenting then avoid the need for decompression (first rib resection), or serve as an adjunct ?

The findings suggest that stenting across the thoracic outlet using novel dedicated venous stents may be a viable treatment for axillosubclavian vein thrombosis, potentially expanding strategies for thoracic central vein obstruction. @cirsesociety @KeckMedicineUSC

Management of central venous catheter-related occlusions includes thrombolysis, catheter exchange over a guidewire, and angioplasty. In cases of persistent stenosis, stent placement may be performed. @cirsesociety @KeckMedicineUSC

@BostonCollege Let’s get some in the bookstore/online !

@Nico____Sanchez 💛❤️

I remember when I was working as a research coordinator before med school, I always thought it was so cool when I saw people wearing college scrub caps in the hospital. Now, I finally got my own @BostonCollege one on Etsy. Go eagles !

A 4 week rotation in the SICU was physically, mentally and emotionally exhausting, but also very useful in the scheme of comprehensive IR training. Much respect to my critical care colleagues - Now back to IR, with paternity leave right around the corner!! #PGY-5
