Concern comes with any new process or system change in healthcare, and the increasing use of online patient portals in radiology is no exception. However, worries about patient anxiety, an uptick in office phone calls or misinterpretation of reports seem to have been kept at bay, as the adoption of portals is offering a host of promising benefits for patients and radiologists alike.


 - Big Data

Big data is more than a buzzword, it is the future of medicine. More sophisticated ways of capturing and—perhaps more importantly—analyzing data will revolutionize healthcare, making it more effective, efficient and personalized. This issue's cover story asks several Big Data thought leaders what this means for radiology.

The presence of peritumoral contrast enhancement is a MRI feature that may be solely used to diagnose high-grade soft-tissue sarcomas (STS), according to a study published in the July issue of Radiology.

 - CAD

Combined analysis of coronary CT angiography (CTA) and stress dual-energy CT (DECT) myocardial perfusion reduces the number of false-positives in a high-risk population for coronary artery disease (CAD) and outperforms coronary CTA alone for the detection of morphologically and hemodynamically significant CAD, according to a study published in the July issue of the American Journal of Roentgenology.
