I built NavRad Anatomy, a free tool with an AI Guide that makes it simpler to learn clinically important imaging anatomy.
To read scans, you need to know the anatomy. But there’s a lot to learn, and it’s hard to know what matters.
With this app, you can scroll through real scans with labels and colour-coded overlays, filter the structures you want to see, learn essential anatomy with key clinical pointers, or ask the AI Guide:
“Walk me through the liver segments” (see video)
“Teach me the segments of the internal carotid artery”
Or even: “Just show me the basics”
Then test yourself by asking it to quiz you.
Works on your phone or computer, so you can learn on the go.
See it in action 👇
Try it at anatomy.navigatingradiology.…, or click "Anatomy" in Navigating Radiology.

World Spine Day | October 16
The spine presents unique challenges in radiation oncology, particularly when treating metastatic disease near the spinal cord and other critical structures.
In recognition of #WorldSpineDay, we're highlighting an Applied Radiation Oncology article exploring stereotactic body radiation therapy (SBRT) for oligometastatic spine disease, including patient selection, treatment considerations, and the importance of multidisciplinary care.

New in the @IJROBP : breast RT + SIB in 5 fractions, with low objective late side effects at 5 years.
Congratulations to Maia Dzhugashvili this paper forms part of her PhD thesis and all coauthors!

Fantastic work @StephenChunMD and team!! Important, practical guidance for a challenging group of pts.
Definitely worth a read!

🎯upfront SRS
Proud of work co-led by Emily Miao & Emily Wo uniting 11 centers for the largest cohort of tx-naive EGFR+ NSCLC brain mets. Genomic subtype drives CNS outcomes: L858R & atypical mutations benefit most from upfront SRS. sciencedirect.com/science/ar… @MSKCancerCenter @MSK_RadOnc

News from #ASTRO26: Ultra-low-dose radiation therapy relieves bone pain from multiple myeloma
Multi-institutional trial finds one- or two-session radiation therapy approach controlled pain with almost no side effects, supporting earlier referral for palliative treatment.
As seen in @Medscape, @medpagetoday, @ASCOPost, & more. Presented by Leslie Ballas, MD, FASTRO, from Cedars Sinai.

I think it can, and thus no longer add a CTV for LS-SCLC or NSCLC (any stage).

MR-guided SBRT + focal boost in intermediate-risk prostate cancer 🎯
27 pts | 5-year follow-up
• 40 Gy/5 fx + 45 Gy DIL boost
• 5-y bPFS: 93%
• Acute DLT: 0%
• Late G3 toxicity: 1/27
• PSA nadir: 0.23 ng/mL
• No PC-specific deaths
🤖 Made with AI

Great take home points by @CJTsaiMDPhD regarding how to think about SBRT for oligoprogressive stage IV NSCLC. For those who aren’t aware, she’s the PI of the CURB & CURB2 randomized trials. #ASTRO26

Craniospinal Irridation Protons must be better than Photons?!?
According to MDACC study not so much
· No diff TTP, AEs, OS, CBCs
· VMAT assoc w/ lower odds hospitalization

Post-prostatectomy RT in just 5 fractions? 👀
Ferrario et al and POPART team reports 100 pts treated with prostate-bed SBRT (32.5 Gy/5 fx):
• Late ≥G2 GU toxicity: 8.5%
• Only 1 late G2 GI event
• Just 3 in-field relapses
• 30-mo biochemical control: 74%
Very encouraging local control and toxicity—but urinary QoL remains important to watch.
