Holographic lenses focus ultrasound for brain imaging
August 8, 2019 -- Better brain imaging, or even drug delivery, may be feasible due to the pioneering work of Spanish researchers. They have developed a technique for 3D printing holographic lenses that focus ultrasonic sound waves in the brain.  Discuss
What's gone wrong at the Karolinska?
August 7, 2019 -- Regular articles continue to appear in Swedish newspapers about the huge building and corruption scandal at the New Karolinska Hospital. Many doctors are leaving, patients are suffering, and some observers think the scandal is so large that it can never be thoroughly investigated. The Maverinck tells the story.  Discuss
Biennial CT lung screening matches annual follow-up exams
August 6, 2019 -- A new analysis of the Multicentric Italian Lung Detection trial has shown that biennial CT lung cancer screening was just as effective as annual screening in reducing the risk of lung cancer and all-cause mortality. The study was published in the September issue of the European Journal of Cancer.  Discuss
How appropriate are requests for CT scans of aorta?
August 6, 2019 -- Emergency physicians must do more to assess the risk of acute aortic syndrome, while hospital doctors and general practitioners need to supply more precise and complete clinical information when requesting CT scans of the aorta, according to the findings of a new U.K. study.  Discuss
Most CCTA scans prove valuable for FFR-CT analysis
July 30, 2019 -- New European-led research suggests clinicians can use nearly all coronary CT angiography (CCTA) scans for fractional flow reserve CT (FFR-CT) analysis with simple adjustments to scanning protocols, such as minimizing slice thickness, controlling patient heart rate, and using dual-source or wide-coverage single-source CT units.  Discuss
Data validation promises to make or break AI
July 24, 2019 -- In June, Ranga Yogeshwar, a physicist and science journalist from Luxembourg, made some competent and critical comments about artificial intelligence (AI) and expressed his concerns about data validation. The Maverinck tells the story in his latest column.  Discuss
Act now on handling of serious findings, urges new report
July 19, 2019 -- A government-funded, independent U.K. healthcare agency has published detailed recommendations about how to improve the handling of serious unexpected findings on patient scans by hospital staff. The Royal College of Radiologists has endorsed the report.  Discuss
Which imaging modality is best for ovarian cancer?
July 4, 2019 -- FDG-PET/CT is more accurate than contrast-enhanced CT for detecting primary ovarian cancer, but due to CT's wide availability, cost-effectiveness, and quick interpretation by junior radiologists, it is preferred on a daily basis, attendees learned at the recent World Congress on obstetrics and gynecology in London.  Discuss
3D-printed guides optimize pelvic tumor surgery
July 3, 2019 -- Using 3D-printed surgical guides based on CT scans enabled researchers from Spain to improve the accuracy of, and potentially reduce operating times for, the surgical removal of pelvic tumors in a new study, presented at the recent Computer Assisted Radiology and Surgery 2019 congress in Rennes, France.  Discuss
Cinematic rendering illuminates postmortem CTA
July 2, 2019 -- Researchers from Belgium have used the highly photorealistic visualization provided by cinematic rendering technology to enhance their understanding of CT angiography (CTA) scans during postmortem analysis, according to an article recently published online in Diagnostic and Interventional Imaging.  Discuss
