Three things that mattered
Gadolinium-free abbreviated liver MRI synthesises all contrast sequences from pre-T1 alone
Zhang Y et al. (Radiology: AI) validated Li-DiffNet across 1,008 patients in 4 centres: DL-SBH-aMRI reaches sensitivity 77.9-88.7% and specificity 91.6-93.1%, non-inferior to conventional complete MRI. Eliminates gadolinium risk for cirrhotic patients with renal impairment, a direct path to surveillance MRI without contrast agents.AI decision support avoids 28 prostate biopsies missing just 1 GG2 cancer across 6 UK centres
Sushentsev N et al. (European Radiology) validated an AI-DSS integrating PI-RADS, automated PSA density, and DL risk scores in 252 men at 6 UK centres. Grade selectivity +70%, biopsy efficiency +79%, selective avoidance +143% at the 31% detection threshold. The 28-to-1 ratio provides a quantified benefit/risk frame for NHS integrated diagnostic centre adoption decisions.RCR Global AI Conference and Workforce Census: 75% of UK departments use AI but workload has not fallen
The RCR 2nd Annual Global AI Conference (QEII Centre, London, 29-30 June, 800+ clinicians) coincided with publication of the 2025 Workforce Census: AI adoption reached 75% of UK radiology departments (+6%), yet overall workload has not decreased. The RCR recommends prioritising AI for administrative tasks before clinical detection. Keynote by Prof. Curtis Langlotz (Stanford AIMI, RSNA President) projected AI workforce effects over 5 years.

Industry & regulation
Deepnoid M4CXR: Korea Class III clearance for generative AI radiology report generation (26 June)
Korea MFDS granted Class III clearance (highest risk) to M4CXR for free-text report generation across 41 chest disease categories. Trained on 10M+ image/report pairs. Claimed first generative AI radiology reporting tool cleared in Korea. FDA submission in preparation.RADIN Health deploys AI radiology platform at 4 additional UHS Nevada hospitals (26 June)
Cloud-native PACS, Dictation AI, and RADIN Select platform expanded to 8 sites in Nevada (serverless AWS). Reflects accelerating cloud-PACS plus AI bundle adoption over legacy systems.Lumitron receives $50M from Hancock Prospecting for HyperVIEW oncology imaging and VHEE radiotherapy (29 June)
Hancock Prospecting (Gina Rinehart) invested $50M with option to $100M to support commercial scale-up of the HyperVIEW platform for advanced oncology imaging and FLASH VHEE radiotherapy. Three systems destined for Australia in a world-first deployment.
Conferences & voices
The RCR 2nd Annual Global AI Conference (QEII Centre, London, 29-30 June, 800+ clinicians) centred on safe and practical implementation, with keynote by Prof. Curtis Langlotz (Stanford AIMI, RSNA President) projecting AI workforce effects over 5 years. The simultaneously published RCR 2025 Workforce Census found 75% of UK radiology departments now use AI clinically (+6% vs 2024), yet overall workload has not decreased. Woojin Kim (HOPPR CMIO, FSIIM) launched Presto Agent (24 June), bringing AI draft reporting into existing PowerScribe workflows. Amine Korchi continues active LinkedIn commentary on the gap between investor rankings and the actual clinical adoption footprint of European radiology AI companies.
