Making sense of scattering: Seeing microstructure through shear waves.

The physics of shear waves traveling through matter carries fundamental insights into its structure, for instance, quantifying stiffness for disease characterization. However, the origin of shear wave attenuation in tissue is currently not properly understood. Attenuation is caused by two phenomena: absorption due to energy dissipation and scattering on structures such as vessels fundamentally tied to the material's microstructure.

The Safety and Effectiveness of Hepatic Transarterial Embolic Locoregional Therapy in Patients with Contraindications to Hepatectomy after Portal Vein Embolization.

The safety and effectiveness of hepatic transarterial embolic locoregional therapy (LRT) was assessed, including transarterial chemoembolization (TACE) and transarterial radioembolization (TARE), in patients who underwent portal vein embolization (PVE) before major hepatectomy in whom surgery was then contraindicated. Adverse events (AEs) were graded according to the Society of Interventional Radiology classification of AEs. Tumor response was assessed based on the Response Evaluation Criteria In Solid Tumors 1.
