Breast Ultrasound Volume Sweep Imaging: A New Horizon in Expanding Imaging Access for Breast Cancer Detection.

Objective: The majority of people in the world lack basic access to breast diagnostic imaging resulting in delay to diagnosis of breast cancer. In this study, we tested a volume sweep imaging (VSI) ultrasound protocol for evaluation of palpable breast lumps that can be performed by operators after minimal training without prior ultrasound experience as a means to increase accessibility to breast ultrasound.

Methods: Medical students without prior ultrasound experience were trained for less than 2 hours on the VSI breast ultrasound protocol.

Evaluation of Splenic Artery Embolization Technique for Blunt Trauma.

Introduction: Evaluate outcomes and radiation exposure across different splenic artery embolization (SAE) techniques for splenic injuries secondary to blunt trauma.

Methods: This retrospective cohort study included patients 18 years of age or older who underwent SAE for splenic injury after blunt trauma from January 2011 to June 2019.

Results: Sixty patients underwent angiography for splenic injury after blunt traumatic injury.

Botox-induced muscle paralysis alters intracortical porosity and osteocyte lacunar density in skeletally mature rats.

Reduced mechanical loading can lead to disuse osteoporosis, resulting in bone fragility. Disuse models report macroscopic bone loss due to muscle inactivity and immobilization, yet only recently has there been quantification of the effects of disuse on the vascular pores and osteocyte network, which are believed to play an important role in mechanotransduction via interstitial fluid flow. The goal of this study was to perform a high-resolution analysis of the effects of muscle inactivity on intracortical porosity and osteocyte lacunar density in skeletally mature rats.
