Background: Bone age assessment is essential for evaluating growth and pubertal disorders, but manual methods such as the Greulich-Pyle atlas are subject to inter-observer variability. Automated tools like BoneXpert may improve accuracy and consistency.

Objective: To validate the accuracy and reliability of BoneXpert, an automated bone age assessment tool, compared to traditional manual methods performed by paediatric endocrinologists and radiologists in a multiethnic paediatric cohort in Singapore.

Article Synopsis
  • The study aimed to evaluate the need for prophylactic embolization of extrahepatic vessels in patients with hepatocellular carcinoma (HCC) undergoing yttrium-90 selective internal radiotherapy (Y SIRT) using catheter-directed computed tomography hepatic angiography (CD-CTHA).
  • Conducting a retrospective analysis of 186 HCC patients between 2010 and 2015, the researchers found that only 18.8% required embolization of extrahepatic vessels, while achieving a 99.5% technical success rate for Y SIRT.
  • The findings suggest that using CD-CTHA for Y SIRT results in a low incidence of complications, with only a few

Purpose To compare lesion primary patency and restenosis rates between drug-eluting balloon (DEB) percutaneous transluminal angioplasty (PTA) and conventional balloon PTA (cPTA) in the treatment of arteriovenous fistula (AVF) and arteriovenous graft (AVG) stenosis. Materials and Methods In this prospective study, 119 participants (mean age, 59.2 years; 79 men, 40 women) with failing AVFs (n = 98) or AVGs (n = 21) were randomly assigned to undergo either DEB PTA (n = 59) or cPTA (n = 60) from January 2012 to May 2013.
