U.K. teleradiology: Present and future trends
Independent teleradiology in the U.K. is in a growth phase as radiology service provision in the National Health Service is under pressure and new models of healthcare emerge. But has radiology become a victim of its success? Past President of the British Institute of Radiology Dr. Stephen Davies explores this.

Early FAPI-PET scans match 60-minute scans for lung cancer staging
By Will Morton
By convention, most molecular imaging tracers such as F-18 FDG are injected one hour prior to PET scans to allow time for uptake of the tracer by tumors.

AI may provide early breast cancer alerts from mammograms
By Amerigo Allegretto
Commercial AI systems could provide early alerts for breast cancer by picking out early signs of the disease on mammograms.
June 9, 2026
Screening mammograms and AI score changes are depicted over time in two individuals with screen-detected cancer. Full-field digital mammograms show craniocaudal (top) and mediolateral (bottom) views of the left and right breast. The description below each mammogram indicates whether AI scores from three AI-based computer-aided detection systems (AI-1, AI-2, and AI-3) were above or below the 90th percentile. (A) Mammograms from three screening time points (in 2009, 2011, and 2014) in an individual who was diagnosed in February 2014 (at age 73 years) with a left-sided 25-mm grade 2 invasive breast carcinoma, no special type (arrow). Mammographic breast density was classified as BI-RADS B on all three mammograms. (B) Mammograms from four screening time points (in 2009, 2011, 2013, and 2015) in an individual who was diagnosed in October 2015 (at age 65 years) with a left-sided 45-mm grade 2 lobular carcinoma (arrow). Mammographic breast density was classified as BI-RADS C on all four mammograms. Screen-detected cancers were defined as those diagnosed within 90 days for individuals who were recalled at screening (*).
Tattoo pigments can have significant impact on imaging
By Philip Ward
Tattoos can appear as shadows or artifacts on an x-ray, causing confusion during interpretation. Research presented at the U.K. Imaging and Oncology congress has provided new data on which tattoo inks have the greatest impact.

SERAM 2026: Biparametric MRI cuts time and costs in prostate cancer imaging
By Claudia Tschabuschnig
A study presented at SERAM 2026 suggests that biparametric MRI (bpMRI) can reduce exam time and costs in patients with clinically significant prostate cancer.

Biparametric prostate MRI identified clinically significant Gleason 3+4 prostate cancer using T2-weighted imaging, diffusion-weighted imaging, and ADC mapping alone.
SERAM 2026: AI chest triage cuts referrals without raising CT use
By Claudia Tschabuschnig
A real-world implementation study from a Spanish regional hospital suggests that AI-assisted chest radiograph triage may reduce specialist referrals without driving additional CT imaging.

An AI system highlights multiple abnormalities on a chest radiograph, including a pulmonary nodule (nódulo pulmonar), pleural effusion (derrame pleural), and alveolar syndrome/consolidation (síndrome alveolar).
AI detects lung cancer nodules well but shows low specificity
By Kate Madden Yee
The finding suggests the models offer “a potential role as adjunctive tools for ruling out malignancy” rather than classifying it.
