DSCT edges out 64-slice CT in coronary artery imaging
January 8, 2010 -- Coronary CT angiography performed on dual-source CT (DSCT) confers a slight advantage in image quality with slightly fewer nondiagnostic vessel segments compared to 64-detector-row CT. Calcification remains a challenge with both types of scanners, but it's slightly less problematic with dual-source systems, say researchers from the University of Rome.

Their study found that MRI is a useful and accurate adjunct to ultrasound to diagnose the potentially life-threatening condition.
DTI beats standard MRI in predicting early memory loss, study shows
January 6, 2010 -- Italian researchers say that MRI with a diffusion tensor imaging (DTI) technique appears to be superior to conventional MRI in detecting brain changes that predict future memory decline, according to a study published online on January 6 in Neurology.
DNA defect predicts RT outcome for endometrial cancer
January 6, 2010 -- Radiation therapy (RT) may not be an effective treatment for women diagnosed with endometrioid endometrial cancer whose tumors have a DNA deficiency, according to preliminary research from the Canary Institute for Cancer Research in Las Palmas, Spain.
Prostate cancer patients regain potency after EBRT
January 6, 2010 -- If a group of about 100 men predominantly in their 60s and 70s is typical, prostate cancer patients who receive external-beam radiation therapy (EBRT) face a decline in sexual function for only a two-year period following treatment.
