MRI could replace DRE for prostate cancer staging
July 15, 2026
A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.

Large Korean study adds evidence on contrast media hypersensitivity
By Claudia Tschabuschnig
A Korean study of almost 116,000 contrast media recipients adds new evidence on hypersensitivity risk factors, but a European expert says the findings should be interpreted in the context of current European practice.

MRI false positive for additional disease, (top to bottom): A. Index lesion—grade 2 invasive ductal carcinoma; B. MRI lesion two, upper inner quadrant: Stromal sclerosis and columnar cell change; C. MRI lesion three, upper outer quadrant: No ultrasound correlate, no malignancy on follow-up; D. CEM marked background parenchymal enhancement with a unifocal retroareolar lesion demonstrating wash-out on delayed MLO. Images are republished under a Creative Commons license (CC BY 4.0).

The cost of AI, and finding its breakeven point
By Claudia Tschabuschnig
Who pays, what, where, and when: speakers at the Royal College of Radiologists' Global AI Conference dug into what AI actually costs and when, if ever, it pays for itself.

Who's paying, and for what, is the question that actually decides whether AI in healthcare gets funded.
AI aims to decode targeted radiotherapy response
By Claudia Tschabuschnig
Same administered activity, different results. Speakers at the Royal College of Radiologists’ 2nd Annual Global AI Conference argued AI could help move targeted radionuclide therapy beyond a one-size-fits-all approach toward more precise, personalized treatment.

Experts at the Royal College of Radiologists’ 2nd Annual Global AI Conference discussed how AI could help move cancer care toward more personalized treatment, from targeted radionuclide therapy dosing to drug discovery.
RCR: Agentic AI is off the leash, and already a workhorse for health systems
By Claudia Tschabuschnig
The technical crowd took the stage at the 2nd Annual Global AI Conference in London last week, to show radiologists where agentic AI is running, how it operates across a spread of autonomy, and why only the highest tiers demand serious governance.
