CT-based radiomics reveals prostate cancer risk
Using machine learning, U.K. and Dutch researchers have developed prediction models to identify textural and intensity-based features imperceptible to human observers, and to associate them with commonly used measures of disease progression in prostate cancer.

Germans use spectroscopy to cut beam-range uncertainty
German scientists are convinced that measuring the energy of gamma rays emitted during helium-ion radiotherapy can provide real-time verification of the beam's range in the patient. They have shown how to define the size of the range error in particle therapy, allowing more precise treatments with greater sparing of healthy tissue.

Dual detector combines nuclear and fluoroscopic imaging
Dutch researchers have demonstrated the feasibility of using a flat-panel x-ray detector combined with a gamma camera to allow simultaneous acquisition of fluoroscopic and nuclear images. The instrument could provide clinicians with anatomical information not currently available using nuclear imaging alone.
