🩻 CT AI detected 98% of small pancreatic cancers

Good morning, there. A Radiology study reported 98% sensitivity for CT AI on pancreatic cancers 20 mm or smaller.

I see this as a practical second reader for subtle pancreatic findings on routine CT. The noncontrast result matters because many early clues appear outside pancreas protocols.

Would this change how you review noncontrast abdominal CT?

Here's what you need to know about Radiology AI last week:

• 🩻 CT AI catches smaller pancreatic cancers

• Radiology AI recall risk gets quantified

• RSNA shows why AI integration is standards work

• Mammography AI scores rise years before cancer

• Plus: 6 FDA approved devices & 4 new papers.

🩻 CT AI catches smaller pancreatic cancers

RadAI Slice: This Radiology paper stands out for small tumor sensitivity on both contrast and noncontrast CT.

The details:

• 2,251 patients from 2007 to 2022 across multiple institutions

• CECT AUC was 0.99, matching the six reader mean

• NCCT AUC was 0.93 versus 0.91 for readers

• Tumors 20 mm or smaller had 98% sensitivity on CECT and 86% on NCCT

• Analysis took 20 to 22 seconds per patient versus 63 to 78 seconds

Key takeaway: The practical shift is earlier second reader support for pancreatic cancer signs, especially when CT was not ordered for a pancreas indication.

⚠️ Radiology AI recall risk gets quantified

RadAI Slice: This analysis puts useful numbers behind the safety discussion around cleared imaging AI.

The details:

• 903 FDA authorized health AI devices from 1995 to 2024 were analyzed

• 43 devices were recalled, a 5% overall rate

• Radiology had 692 devices and 30 recalls, a 4.3% rate

• Radiology AI was 52% more likely to face recall than other specialties

• Missing clinical study data and off label use were key risk factors

Key takeaway: This shifts evaluation from clearance alone to evidence quality, intended use discipline, and postmarket monitoring.

🔌 RSNA shows why AI integration is standards work

RadAI Slice: This Radiology review makes deployment feel less about models and more about plumbing.

The details:

• Radiology Reimagined has run at RSNA since 2020

• More than 20 vendor partners join each annual demonstration

• Scenarios now span ordering, acquisition, reporting, follow up, billing

• Standards include DICOM, HL7 FHIR, IHE, FHIRcast, and multimedia reporting

Key takeaway: The practice lesson is clear, AI adoption depends on interoperability, not another standalone result box.

🎀 Mammography AI scores rise years before cancer

RadAI Slice: This Swedish screening analysis gives a measured look at AI as an early risk signal.

The details:

• 31,394 women and 88,963 screening exams were analyzed

• 12,072 women were later diagnosed with breast cancer

• At 10 years, AI flagged 12.7% to 17.0% of future cancers at 90% specificity

• At 4 years, flagged cancers rose to 24.2% to 25.2%

• AUC was 0.63 to 0.67 versus 0.57 for density

Key takeaway: This supports AI as a longitudinal risk cue, but action on early alerts will need clear supplemental imaging pathways.
