"Kids are not simply little adults."

This adage is repeated countless times throughout med school re: physiology/pharma.

I think it should apply equally to #AI. That's why this headline from @AuntMinnie concerns me greatly.

bit.ly/3xH7oX4 In the referenced article, the authors set out to validate @Lunit_AI CXR tool on a cohort of pediatric CXRs.

The authors explicitly state in the abstract that the tool was developed for ADULTS, not kids.

Situation: You’re covering #Neurorad CT-guided biopsies and this case shows up on your list.

Older patient with recently diagnosed clear cell RCC. Lytic lesion in the upper sacrum seen on CT Abd/pelvis.

How do you approach it? #SpineIntervention
1/6 Some options:
1. Anterolateral approach along the iliac bone.
👎 Long path, lots of bone to drill through.

2. Drill through the lateral aspect of the sacral arch to pass in between the thecal sac and the S1 nerve root.
😕 Durotomy risk 💦 and potential seeding 🫣

What else?
