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.
It's time to ditch your old gear, ESR says
September 22, 2014 -- Every healthcare facility or authority should have a plan for upgrading or renewing imaging equipment, and the plan should look forward at least five years and be updated annually, according to a statement issued on 18 September by the European Society of Radiology (ESR).
Hricak: Imaging, radiation oncology increasingly work as one
September 19, 2014 -- Imaging is central to the unprecedented wave of medical specialties converging on cancer care. But it will take more than what today's radiologists are trained for to better understand cancer's mysteries, according to global cancer imaging pioneer Dr. Hedvig Hricak, PhD.
PET/CT bolsters lymphoma survival predictions
September 17, 2014 -- PET/CT outperforms CT alone in measuring treatment response and predicting survival in patients with follicular lymphoma, and therefore should be used routinely in clinical practice, according to research published on Thursday in Lancet Haematology.
Silicon photomultipliers ideal for PET/MRI
September 11, 2014 -- The introduction of combined PET/MRI scanners was enabled by the replacement of photomultipliers with solid-state PET detectors, such as avalanche photodiodes, which can operate inside the MRI environment.
