The aftermath of COVID-19: generalized anxiety disorder and burnout among radiology practitioners and interns in Saudi Arabia.

Background: The coronavirus disease (COVID-19) pandemic has presented unprecedented stressors and difficulties for healthcare professionals. This study explored the prevalence of generalized anxiety disorders and burnout among radiology practitioners and interns in various hospitals in Saudi Arabia after the end of the COVID-19 global public health emergency.

Methods: A cross-sectional survey of 230 radiology practitioners and interns was conducted between October and November 2023.

Influence of Phase Change Droplet Activation and Microbubble Cavitation on the Microenvironment of Hepatocellular Carcinoma.

Objective: Both microbubble ultrasound contrast agents and acoustic phase change droplets (APCD) have been explored in hepatocellular carcinoma (HCC). This work aimed to evaluate changes to the HCC microenvironment following either microbubble or APCD destruction in a syngeneic pre-clinical model.

Methods: Mouse RIL-175 HCC tumors were grown in the right flank of 64 immunocompetent mice.

Activation of Phase Change Contrast Agents Using Ionizing Radiation.

The feasibility of activating phase change contrast agents (PCCA) made from Definity (Lantheus Medical Imaging) using X-rays was investigated. A 10 mL of Definity PCCA (0.1 mL PCCA/mL) were injected into gelatin phantoms and irradiated using doses of 0, 30, 50, and 100 Gy.
