Developing a nearly automated open-source pipeline for conducting computational fluid dynamics simulations in anterior brain vasculature: a feasibility study.

Intracranial aneurysms (IA) pose significant health risks and are often challenging to manage. Computational fluid dynamics (CFD) simulation has emerged as a powerful tool for understanding lesion-specific hemodynamics in and around IAs, aiding in the clinical management of patients with an IA. However, the current workflow of CFD simulations is time-consuming, complex, and labor-intensive and, thus, does not fit the clinical environment.

Ultrasound-guided percutaneous transjejunal creation of neoanastomosis for the treatment of bilioenteric anastomotic occlusion.

A stricture of the bilioenteric anastomosis is a known complication of pancreaticoduodenectomy surgery and pediatric liver transplant. Occasionally, a complete biliary occlusion is encountered that cannot be treated utilizing endoscopic or conventional interventional radiology blunt recanalization techniques. In this article, we report 2 cases of successful sharp percutaneous ultrasound-guided retrograde creation of bilioenteric neoanastomosis in the setting of a complete biliary occlusion following Whipple surgery and liver transplant respectively.

PET/CT-Based Absorbed Dose Maps in Y Selective Internal Radiation Therapy Correlate with Spatial Changes in Liver Function Derived from Dynamic MRI.

Functional liver parenchyma can be damaged from treatment of liver malignancies with Y selective internal radiation therapy (SIRT). Evaluating functional parenchymal changes and developing an absorbed dose (AD)-toxicity model can assist the clinical management of patients receiving SIRT. We aimed to determine whether there is a correlation between Y PET AD voxel maps and spatial changes in the nontumoral liver (NTL) function derived from dynamic gadoxetic acid-enhanced MRI before and after SIRT.
