ACR 2017: Radiation dose varies in head CTs of children
A large analysis of pediatric head CT scans across the U.S. showed surprisingly large variations in radiation dose that increased as children grew older, according to results presented at this week's American College of Radiology (ACR) meeting in Washington, DC.

'Deep patient' may point the way to better care
SAN JOSE, CA - With so much research focused on disease diagnosis using artificial intelligence, it's easy to overlook a largely untapped resource that could wield at least as much firepower to reinvent healthcare for the better. That resource is the deep patient, according to a May 11 talk at the NVIDIA GPU Technology Conference.

Photon-counting breast CT shows promise
Tests of a prototype photon-counting detector breast CT scanner show that the system could be useful as an adjunct to low-dose breast CT by separating the energy levels of different types of materials within the breast to assess tissue composition and improve cancer diagnosis.

DVA reduces radiation exposure during interventions
By Will Morton
Digital variance angiography (DVA) shows promise in reducing radiation doses to patients during certain interventional radiology procedures.

Pelvic (A), femoral and popliteal (B), and cruro-pedal (C) region. The summated digital variance angiography (DVA) image significantly enhances image quality compared to the digital subtraction angiography (DSA) series I–IV (depicting 4 out of 28 (A), 48 (B) and 28 (C) DSA images) of the low dose (LD) acquisitions. Enhancements of iodinated contrast medium (ICM) by DVA depict small vessel structures in detail while the conventional DSA offers a reduced contrast-to-noise ratio (CNR) using LD acquisitions for standalone diagnostic interpretations.
