Tami Freeman, PhD[email protected]Clinical NewsPhoton counting can assist in energy-resolved imagingPhoton-counting detectors based on cadmium telluride and cadmium zinc telluride offer many advantages for x-ray imaging. Their energy discriminating properties improve material decomposition, eliminate electronic noise, and can reduce patient dose, but detectors are hindered by a limited count rate relative to the photon flux.August 4, 2013Molecular ImagingMRI method images glucose uptake in vivoAltered glucose metabolism is associated with a range of pathological conditions. In particular, solid tumors have more glucose consumption compared with healthy tissue -- a feature that can be used for tumor detection, monitoring disease progression, and evaluating therapy response, U.K. researchers found.July 17, 2013Clinical NewsLower limb DEXA analysis can boost bone densitometryDual x-ray absorptiometry (DEXA) is typically used to measure bone mineral density at the spine or hip to diagnose osteoporosis. But some conditions alter bone density at other skeletal sites, leading to increased fracture risk that's not reflected by standard DEXA measurements. U.K. researchers are now using lower limb DEXA analysis to extend the applications of bone densitometry.July 11, 2013Molecular ImagingProton therapy shows promise in childrenChildren are not just little adults, Dr. Anita Mahajan told attendees at the recent Particle Therapy Co-Operative Group meeting in Essen, Germany. Proton therapy is an ideal fit for children, but comes with unique challenges and constraints, she said.July 3, 2013Clinical NewsProton therapy: How imaging can helpDelegates at the recent Particle Therapy Co-Operative Group annual meeting heard how introducing imaging techniques into the proton therapy workflow can improve treatment accuracy. Keynote speaker Martijn Engelsman, PhD, from Delft University of Technology in the Netherlands described how proton therapy can benefit from various image-guidance techniques.June 23, 2013Clinical NewsTime-of-flight PET detectors: The next generationDetectors for use in time-of-flight PET must offer high detection efficiency, good spatial and energy resolution, and excellent timing resolution, as well as provide depth of interaction information. A promising candidate that meets all of these requirements is the monolithic scintillator detector.June 17, 2013Clinical NewsESTRO: Proton CT has potential to improve patient careEvidence is growing that proton CT can enable more accurate treatment planning and range verification for proton therapy. Its emergence as a way to improve the precision of proton therapy was discussed at a recent forum of the European Society for Radiotherapy and Oncology (ESTRO) held in Geneva.May 6, 2013Molecular ImagingSecond cancer risks warrant rigorous investigationHow can we estimate the risk of inducing second cancers in patients receiving radiotherapy? Ionizing radiation is known to cause cancer, and the risk of inducing second cancers in patients undergoing radiotherapy cannot be ignored.May 1, 2013Clinical NewsNew software simplifies intensity-modulated radiotherapyResearchers in Germany have developed a new approach for making target treatment plans for intensity-modulated radiotherapy easier. They've developed a method to make this process easier, as described in the 21 March issue of Physics in Medicine and Biology.April 15, 2013Molecular ImagingPET features provide boost for therapy response predictionTextural variables derived from PET images reveal intratumor heterogeneity and may help predict a patient's response to chemotherapy. Researchers explored their associations with the clinical responses of breast cancer patients in a recent article published in Physics in Medicine and Biology.February 17, 2013Previous PagePage 8 of 10Next PageTop StoriesCTSafety concerns lead to suspension of CT service at Belgian hospitalTen patients at a general hospital in Dendermonde, East Flanders, became unwell after undergoing CT. An investigation is underway, and the CT service was briefly suspended, according to media reports.MRIMRI shows how brain maintains 'representation' of phantom limbsMRIGadolinium in ... beer?Artificial IntelligenceBeyond the algorithm: Embedding AI into imaging workflowsRadiology EducationUkrainian radiologists train, collaborate throughout war
