AI model classifies aortic dissection, rupture on CT
September 17, 2019 -- An artificial intelligence (AI) algorithm can accurately detect aortic dissection and rupture on postcontrast CT images, enabling radiologists to prioritize interpretation of these emergent cases, according to research published online on 12 September in the Journal of Digital Imaging.  Discuss
Training in FDG-PET/CT advances lung cancer outcome
September 16, 2019 -- Additional training in FDG-PET/CT to monitor concurrent chemotherapy for patients with stage III non-small cell lung cancer (NSCLC) can significantly extend both overall and progression-free survival, according to an international study published in the October issue of European Journal of Nuclear Medicine and Molecular Imaging.  Discuss
Swiss cast new light on prostate cancer analysis
September 16, 2019 -- Researchers from Zurich have found gallium-68 prostate-specific membrane antigen offers better sensitivity, while multiparametric MRI provides better specificity, especially when determining tumor cell spread beyond the lymph node capsule or when prostate cancer extends into the seminal vesicles.  Discuss
Novel PET method advances in traumatic brain injury
September 13, 2019 -- A research team from the U.K. and Sweden has used dynamic flortaucipir-PET imaging to show that single moderate-to-severe traumatic brain injury can trigger signs of accumulation of neurodegenerative tau protein and lead to cognitive decline.  Discuss
Ga-68 PMSA PET/CT aids in prostate cancer recurrence
September 12, 2019 -- Italian researchers have created a gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) PET/CT-based model to accurately predict which prostate cancer patients are likely to show recurrence. Their study was published on 6 September in the European Journal of Nuclear Medicine and Molecular Imaging.  Discuss
Merging PET and MRI assists in large-vessel vasculitis
September 12, 2019 -- French investigators have combined contrast-enhanced anatomic assessments of MRI with the quantitative measurement of FDG uptake in PET to accurately characterize and differentiate between inflammation and fibrosis in the aortic walls and auxiliary branches of patients with large-vessel vasculitis.  Discuss
U.K. public still trusts NHS, despite mammo screening glitch
September 11, 2019 -- The U.K. public still trusts the breast screening program run by the National Health Service (NHS), despite the recent debacle in which thousands of women were thought to have missed their final invitation to screening, according to a study published on 6 September in BMJ Open.  Discuss
Blood test can give boost to CT lung screening
September 11, 2019 -- New evidence from the U.K. suggests a blood test and imaging-based lung screening exam offers a better lung cancer detection rate than standard clinical care. The findings were presented on 9 September at the World Conference on Lung Cancer in Barcelona, Spain.  Discuss
Mamma Mia! What's the secret to Sectra's success?
September 10, 2019 -- Sectra's strong performance in the global imaging IT market has attracted attention. Our market columnist Stephen Holloway takes a close look at the Swedish company's strategy and approach, and asks whether its success will continue.  Discuss
What influences physicians' cancer screening advice?
September 10, 2019 -- Norwegian researchers have found that an array of factors can influence physicians' behavior when it comes to recommending cancer screening to patients, according to a study published online on 30 August in BMJ Open.  Discuss
