The medical community has viewed the advent of  artificial intelligence(AI) with both fear and excitement. The technology held a major platform at this year ’s Radiological Society of North America conference, and companies like GE Healthcare, Siemens, and  NVIDIAare rapidly rolling out AI-based devices. This onset of machine and deep learning programs has threatened to replace human radiologists. However, according to research from Google Cloud, AI is capable of only automating a portion of a radiologist ’s responsibilities.Google Cloud ’s head of research and development, Jai Li, studied ...

AbstractTo evaluate the association between the index and ring finger ’s (2D:4D) length ratio with the prevalence and severity of radiographic hand osteoarthritis (OA). A population-based sample included 802 males (mean age 46.98 ± 17.10 years) and 738 females (mean age 48.65 ± 16.62 years) who had participated in a Chuvashian skeletal aging study. Age, sex, basic demographics, anthropometric data and X-rays of both hands were acquired. Each hand was visually classified on X-ray as either type 1—index finger longer than the ring finger; type 2—index and ring fin...

AbstractPurposeTo investigate if bone substitutes are strictly necessary to restore the vertebral body height and improve the clinical outcome, in patients with thoracolumbar or lumbar AO type A post-traumatic vertebral fractures, managed with balloon kyphoplasty combined with posterior screw and rod system.Methods105 patients with post-traumatic thoracolumbar spine fracture were recruited. At baseline, the patients underwent a CT and an MRI of the spine. Clinical evaluation was performed, using the Visual Analog Scale (VAS) and the Oswestry Disability Index (ODI), at baseline, 48  h after surgery, at 3-month follow-u...

Previously, we found genistein could sensitize cancer cells to low linear energy transfer (LET) X-rays via inhibiting DNA-PKcs activities. Especially, high-LET heavy ion produces more DNA double strand breaks (DSBs) than low-LET radiation. Thus, the study was designed to investigate the detailed molecular mechanisms of genistein on sensitizing cancer cells to heavy ions.

Authors: Wang D, Lin Y, Chen L, Mo Y, Huang P, Ma R Abstract Developmental dysplasia of the hip (DDH) is one of the most common diseases encountered in pediatric orthopedic departments. Current treatment strategies seek to improve acetabular coverage, the principal defect of acetabular dysplasia, but are not very successful. We developed a guided bone regeneration (GBR) strategy to improve acetabular coverage via bone tissue engineering (BTE). Poly-dl-lactide (PDLLA) membranes were seeded with bone marrow mesenchymal stem cells (BMSCs) to form a BTE complex, which was then implanted into the superior margin of the ...

ConclusionThis study showed an overall 16.3% radiological PCE and 1.4% symptomatic PCE incidence when CAFPS were used due to severe osteoporosis. The symptomatic PCE risk was significant when CAFPS were  >  7 levels; >  14 fenestrated screws; and >  20–25 cc cement volume is used and this may cause PAP increase and right ventricular dilatation.Graphical Abstract

J. Anal. At. Spectrom., 2018, Advance Article DOI: 10.1039/C8JA00029H, PaperJavier Merrill, Victor Montenegro, Michael F. Gazley, Leandro Voisin As altitude increases, air density decreases, and the physics of X-rays being transmitted through air mean that the transmission of low-energy X-rays increases and accordingly the transmission effectiveness of low-atomic weight elements (e.g. Mg, Al, and Si) also increases. Here we assess the performance of pXRF units across a range of pressures. To cite this article before page numbers are assigned, use the DOI form of citation above.

Follow me on Twitter @drClaire Children often complain of being tired. Usually it’s for simple reasons — because it’s the end of a busy day, or because they stayed up late the night before, or because they are trying to get out of doing something they don’t want to do. When kids are sick they are usually tired, and need more rest to get better. But when a child complains all the time, and fatigue starts to get in the way of things they usually enjoy, it could be a sign of a problem. Here are some possible reasons for chronic fatigue in children: Sleep problems. This makes sense, obviously, since if...

AbstractThe purpose of this work was to present body size and tube voltage-dependent equations for optimal selection of image acquisition parameters in guiding clinical X-ray imaging. The dose output of X-ray tubes was expressed as a function of the image acquisition parameters of tube voltage (kVp), tube current –exposure time product (mAs), and body size (d). Dose power (n) to kVp was determined to be a linear function of body size in an earlier phantom study. Tube voltage-dependent attenuation coefficients of water were used to determine the kVp effect on the depth dose of X-rays from the body ’s entrance su...
