US Study Says Third Course of Radiation Therapy May Improve Survival and Symptoms in Children with Recurrent DIPG
According to news from the Icahn School of Medicine at Mount Sinai in the United States on September 2, researchers at the institution released a new study on re-irradiation for recurrent diffuse intrinsic pontine glioma (DIPG). The study shows that carefully selected pediatric patients who receive a third course of radiation therapy after disease recurrence may achieve symptom relief, improved quality of life, and potentially prolonged survival. The related study has been published in Practical Radiation Oncology. DIPG is a highly aggressive pediatric brain tumor that occurs in the brainstem region. The brainstem controls critical life functions such as breathing and movement, so the tumor usually cannot be removed surgically. Data show that DIPG mainly affects children aged 5 to 10, and even...

Russian scientists use 3D-printed tungsten grid to improve X-ray imaging quality, potentially reducing patient radiation exposure
The press service of the Russian Ministry of Education and Science recently stated that a Russian research team has used 3D printing technology to manufacture a tungsten-based anti-scatter grid for X-ray machines, with partition thickness only one-third that of similar products. The researchers believe this achievement could help reduce patient radiation exposure during X-ray examinations while maintaining medical image quality. During X-ray imaging, some rays scatter after passing through human tissue, creating background noise that weakens image contrast. Clinical equipment typically suppresses such interference through anti-scatter grids. Traditional anti-scatter grids are mostly made of lead, but lead has low mechanical strength and imposes high requirements on processing techniques, resulting in...
