Background Climate change, driven primarily by human-induced greenhouse gas (GHG) emissions, poses major risks to human health. Health care contributes 8.5% of GHG emissions in the United States.
View Article and Find Full Text PDFFor more than 2 decades, translational medicine has accelerated basic science discovery into clinical application using a bench-to-bedside framework. Given that climate change represents the single greatest health threat facing humanity, the authors propose extending this framework to now include the bedside to the biosphere. Several potential opportunities in clinical operations, research, and advocacy associated with the use of this framework are provided.

A planetary health framework recognizes that sustaining a healthy planet is essential to achieving individual, community, and global health. Radiology contributes to the climate crisis by generating greenhouse gas (GHG) emissions during the production and use of medical imaging equipment and supplies.

This retrospective study sought to assess the impact of an open access virtual grand rounds program. We tested the hypothesis that virtual grand rounds would advance learning equity by increasing access to learners outside of our institution.

In J-difference editing of lactate, threonine can be co-edited and it contaminates lactate estimates due to the spectral proximity of the coupling partners of their methyl protons. We therefore implemented narrow-band editing 180° pulses (E180) in MEGA-PRESS acquisitions to resolve separately the 1.

The impact of climate change on human health and health equity, the contribution of health care and medical imaging to the climate crisis, and the impetus for change within radiology to create a more sustainable future are covered. The authors focus on actions and opportunities to address climate change in our role as radiologists.

ICM is commonly sold in "single-dose" bottles that require any unused volume to be discarded. Multi-dose bottles have been developed as an alternative packaging method.

The open discussion centered around on challenges facing radiology and specifically focused on the people in our field, including patients, radiologists, and radiology staff. Participants identified numerous opportunities for industry and radiology departments to collaborate to improve equitable access to healthcare, communication with patients, use of appropriate imaging, and the state of the radiology workforce.

The authors hypothesized that a structured, intentional Women in Radiology (WiR) program would increase women faculty members' perceptions of workplace gender equity, satisfaction with pace of professional advancement, interest in research and teaching, and perceptions of work-life balance and mentorship opportunities.
Methods: Components and structure of a sustainable WiR program are described in detail.
The purpose of this study was to define the optimal infusion parameters and operator radiation exposure for yttrium-90 (Y) radioembolization in the VX2 rabbit model of liver cancer. Forty-one rabbits with VX2 were treated with glass microspheres with vial sizes of 1, 3, and 5 GBq. The mean administered activity was 51.

Materials And Methods: Hepatic VX2 tumors were implanted into New Zealand white rabbits, with growth confirmed by 7 T magnetic resonance imaging. Seventeen VX2 rabbits provided 33 analyzed tumors.
Purpose: Portal vein embolization (PVE) is an established neoadjuvant method to induce future liver remnant hypertrophy prior to surgical resection of hepatic tumors. The purpose of our study was to examine the feasibility of PVE with glass Y microspheres (Y90 PVE) in Sprague-Dawley rats. We tested the hypothesis that increased doses of Y90 PVE would increase target lobe fibrosis and atrophy.

Purpose: To evaluate the combination of Y radioembolization (Y90) and drug-eluting bead irinotecan (DEBIRI) microspheres in the VX2 rabbit model.
Materials And Methods: An initial dose finding study was performed in 6 White New Zealand rabbits to identify a therapeutic but subcurative dose of Y90. In total, 29 rabbits were used in four groups: Y90 treatment (n = 8), DEBIRI treatment (n = 6), Y90 + DEBIRI treatment (n = 7), and an untreated control group (n = 8).
Rationale And Objectives: To use a rapid gas-challenge blood oxygen-level dependent magnetic resonance imaging exam to evaluate changes in tumor hypoxia after Y radioembolization (Y90) in the VX2 rabbit model.
Materials And Methods: White New Zealand rabbits (n = 11) provided a Y90 group (n = 6 rabbits) and untreated control group (n = 5 rabbits). R2* maps were generated with gas-challenges (O/room air) at baseline, 1 week, and 2 weeks post-Y90.
