Tami Freeman, PhD[email protected]Molecular ImagingDutch investigate inverse approach to dose paintingDose painting combines anatomic imaging with biological information to define radioresistant tumor subpopulations that are potential targets for dose escalation, according to researchers based in the Netherlands. They're studying how PET can pinpoint regions of high metabolic activity.April 27, 2016Clinical NewsSpectral data enrich mammographySpectral mammography could help reduce breast cancer screening recalls by distinguishing solid lesions from cysts, said researchers from Sweden and the U.K. who have developed a new method to measure the energy-dependent x-ray attenuation of tissue.April 14, 2016Clinical NewsSynchrotron-based breast CT advancesPerforming breast CT with synchrotron radiation enables the use of phase-contrast techniques, which produce images with high soft-tissue contrast. Researchers in Italy are planning the first clinical study of phase-contrast breast CT with synchrotron radiation.February 17, 2016Molecular ImagingHow to select targets for Tc-99m productionRadioisotope technetium-99m (Tc-99m) is traditionally obtained via the decay of molybdenum-99, which is produced in a small number of aging nuclear reactors. The fragility of this supply line has prompted the investigation of alternative manufacturing methods.February 8, 2016Molecular ImagingBeam-on PET tracks proton dose in real-timeExploiting the superior dose deposition of particle therapy for clinical benefit necessitates an accurate technique for verifying dose delivery. Because the treatment beam stops inside the patient, such monitoring requires detection of secondary radiation created when the incident beam interacts with the tissue, Dutch researchers found.November 25, 2015Clinical NewsCardiac ablation: Improving the accuracyShear-wave elastography is showing promise for guidance of focused ultrasound-based cardiac ablation. Researchers from France have designed a transesophageal device that can both deliver high-intensity focused ultrasound and perform imaging.October 26, 2015Clinical NewsWhere next for MRI-guided radiotherapy?Ultimately, MRI guidance could be applied to improve all radiotherapy techniques, including proton therapy. Last month, Bas Raaymakers, PhD, from Utrecht University in the Netherlands took a glimpse into the future and explained why clinical implementation will require large-scale collaborations.October 4, 2015Clinical NewsFrench group wins award for ultrafast ultrasound workA research paper describing a new type of ultrasound that can produce ultrafast 3D videos has won its French authors the 2014 Roberts Prize for the best paper published in Physics in Medicine & Biology (PMB) last year.September 23, 2015Molecular ImagingWomen in medical physics: The current statusHow well represented are women in the worldwide workforce of medical physicists? The IUPESM World Congress, held last month in Toronto incorporated five main congress themes, one of which was "Women in Biomedical Engineering and Medical Physics."July 29, 2015Clinical NewsProton therapy: Randomized trials or model-based selection?Are randomized controlled trials really needed for the rollout of proton therapy? This is a subject of much contention, and it was debated by two leading experts at the 3rd European Society of Radiotherapy and Oncology Forum in Barcelona, Spain.July 2, 2015Previous PagePage 5 of 10Next PageTop StoriesMRIGadolinium in ... beer?Results from a French study offer a "snapshot" of the current status of rare earth element contamination in beverages.Artificial IntelligenceBeyond the algorithm: Embedding AI into imaging workflowsRadiology EducationUkrainian radiologists train, collaborate throughout warMRICE MRI-based radiomics model captures DEB TACE-induced tumor changesCTImaging casts new light on war injuries
