Bottom line:
LI-RADS TRA v2024 with ancillary MRI features improves detection of viable HCC post LRT (especially post TACE) while preserving specificity.

A meaningful step toward improved post-treatment HCC assessment. 📚

How much does new #LIRADS Nonradiation Treatment Response Algorithm (TRA v2024) improve post-treatment #HCC assessment?

New multicenter @Radiology_RSNA study compared LI-RADS v2024 vs v2017 on HBA-MRI & CT.

One important nuance:
Although MRI + ancillary features improved accuracy, interobserver agreement was actually lower on MRI than CT.
Likely because diffusion restriction and T2 hyperintensity are inherently more subjective in the post-treatment setting.

#RadInTraining term close-out. Deeply grateful for an inspiring term with our brilliant team, outstanding leadership of @VChernyakMD, and intensive reviewer training. More than happy to continue as Deputy Editor from 7/2026. #RIT meetings are truly one of my absolute highlights🌟

13/13 Take home points:
TARE staff radiation exposure is generally low, but:
• ¹⁶⁶Ho-PLLA → highest body dose
• ⁹⁰Y-resin → highest hand dose
• IRs → highest overall dose

🧵 How much radiation do staff receive during transarterial radioembolization (TARE)?

New prospective dosimetry data comparing ⁹⁰Y-resin, ⁹⁰Y-glass& ¹⁶⁶Ho-PLLA microspheres across multiple roles in real workflow.

12/13 Practical mitigation tips:
• For ⁹⁰Y-resin: optimize portioning/assembly/application efficiency
• Use distance tools (e.g., long tweezers)
• Training + standardized workflow
• Shielding where feasible (acrylic shielding used in prep)
