The estimated size of chest lymph nodes and lung nodules seen on CT images varies significantly when the same nodes or nodules are examined using lower versus higher doses of radiation, a new study shows. The size of lymph nodes and lung nodules is an important determinant of treatment and treatment success. http://medicalxpress.com/news/2013-04-dose-affects-size-lesions-chest.html Cancer Wed, 17 Apr 2013 00:00:02 EST news285354233 (HealthDay)—Adding computer-aided detection to mammograms finds more early, noninvasive cancers and helps detect invasive cancers at earlier stages, according to a large new study. But the jury's still out as to how worthwhile the extra technology is overall. http://medicalxpress.com/news/2013-04-pricey-computer-aided-mammograms-worth.html Cancer Tue, 16 Apr 2013 05:12:12 EST news285307858 Imagine a hospital where patient data from numerous sources is made accessible to ward physicians with the help of hyperlinks and intelligent indexing. Imagine a healthcare system that hands its patients – not an envelope or a CD-ROM – but an integrated dataset that allows them to truly understand their illness, and even use the Internet to obtain additional information. Imagine a radiologist who uses semantic technologies to navigate smoothly through the myriad imaging data.
