Multifunctional microbubble agents display clinical promise
November 21, 2014 -- Multifunctional microbubble agents are showing great potential for medical applications, particularly superparamagnetic iron oxide nanoparticles, which are used as MRI contrast agents but can be combined with encapsulated microbubbles and provide ultrasound contrast.
Tread carefully on lung cancer screening, U.K. experts urge
November 18, 2014 -- For effective implementation of lung cancer screening, start with a program targeting those most at risk and employ pathways minimizing risk of harm, including those due to overdiagnosis, and then expand as unanswered issues are clarified, U.K. specialists have advocated.
Meeting the challenge of imaging the head and neck
November 17, 2014 -- Today's head and neck radiologists play a key role guiding examinations and reporting them. Dr. Florian Dammann, chair of the German Radiological Society's Head and Neck Diagnostics Working Group, explains more about the subspecialty in this interview.
How a British boy band changed imaging forever
November 10, 2014 -- LONDON - What do circus tricks and a top British boy band have in common? Both had a major impact on the development of imaging during the second half of the 20th century, Dr. Stavros Stivaros, PhD, told the audience at last week's U.K. Royal College of Radiologists annual public lecture.
Sentinel node technique avoids radical surgery, radiation exposure
October 23, 2014 -- Dutch researchers believe they have confirmed the accuracy and safety of a new sentinel node procedure that injects radiotracers in ligaments of women with epithelial ovarian cancer, helping them avoid more invasive, radical surgery.
FDG-PET/CT has mixed results in lung cancer screening
October 21, 2014 -- Lung cancer researchers from Italy have found that FDG-PET/CT is "highly sensitive" in the diagnosis of indeterminate nodules, as well as nodules larger than 15 mm and solid nodules, but less effective with other smaller, subsolid nodules.
PET/MRI matches PET/CT with less radiation for children
October 20, 2014 -- German researchers have found promising evidence that PET/MRI is equivalent to PET/CT for lesion detection in pediatric cancer patients, while at the same time delivering just one-quarter of the radiation dose, according to a study published in the October issue of Radiology.
3D PET can image brain oxygen metabolism
October 17, 2014 -- A state-of-the-art 3D PET scanner can accurately image cerebral oxygen metabolism, as long as appropriate scatter compensation is carried out. In new work, researchers have demonstrated precisely how this can be achieved.
Dual-energy CT develops greater role in brachytherapy
October 10, 2014 -- A group of Canadian and Dutch researchers has developed a brachytherapy dosimetry method that accounts for dose heterogeneity. They have used dual-energy CT to extract these parameters, and the treatment is proving valuable in early stage prostate or breast cancer.
Germans focus on pediatric dose, as crisis deepens
October 1, 2014 -- A special session on radiation protection was a highlight at the recent annual meeting of the German Society for Pediatrics and Adolescent Medicine. It reflected mounting concerns over dose, but also highlighted the crisis facing pediatric radiology.
