Of the diagnostic modalities, MRI is the most energy-intensive modality, consuming up to 60 kWh per scan, followed by CT, which ranges from 1.0 to 11.4 kWh per scan. Lifecycle analyses show that operational energy use far exceeds manufacturing emissions, highlighting the need for energy-saving strategies. Implementing standby and power-off modes, optimizing scan protocols, and using AI-driven efficiency improvements can significantly reduce unnecessary energy use. Additionally, sustainable infrastructure, such as variable-flow cooling systems and strategic equipment placement, can further minimize environmental impact. Nuclear medicine, while relatively lower in energy consumption, relies on energy-intensive radioisotope production, often requiring fossil fuel-powered reactors and extensive transport logistics. Contrast agents in MRI and CT pose contamination risks in wastewater, as they are inadequately removed via conventional treatment plants methods. This results in the accumulation of gadolinium and iodinated byproducts in drinking water sources, posing potential human and ecological risks. Nuclear medicine radioisotopes, including Tc-99, also contribute to long-term contamination concerns. Strategies to mitigate these impacts include urine recycling, contrast separation, and advanced wastewater treatment. Sustainable practices in medical imaging require a multi-pronged approach, combining operational efficiency, renewable energy adoption, and stricter waste management protocols. Future efforts may also focus on promoting low-field MRI, AI-driven scan optimization, and alternative contrast agents, ensuring that radiology departments balance diagnostic efficacy with environmental responsibility.</p>","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251327143"},"PeriodicalIF":2.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Limited existing recommendations from other countries do not consider the unique aspects of the Canadian healthcare system. To address this gap, 17 experts participated in a modified Delphi panel to reach consensus on biopsy-related topics and provide recommendations. The panel was comprised of 12 radiologists, 2 pathologists, and 3 surgeons from 6 provinces across Canada. Panelists engaged in two rounds of anonymized voting, with an in-person discussion held between the rounds. The modified Delphi panel adhered to best practices, including establishing consensus definitions prior to voting, utilizing anonymized voting, and abstaining from communication among panelists before the in-person meeting. A rigorous statistical approach was utilized to analyze the points of agreement and disagreement. Consensus findings covered a wide range of topics, including recommendations for initial biopsy technique based on lesion type and imaging modality, patient management or rebiopsy considerations after the initial biopsy, procedural recommendations (i.e., gauge size, number of samples), patient considerations (i.e., drug allergies, pregnancy). Overall, 347 individual items were included in the final analysis, 286 (82%) of which achieved consensus. These consensus recommendations intend to offer general recommendations to help standardize and improve practices across Canada and were endorsed by the Canadian Society of Breast Imaging. However, they should be evaluated in the context of each individual case and emerging evidence.</p>","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251325500"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143756084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interventional radiology (IR) is a resource-intensive specialty that has not historically emphasized environmental sustainability. This review aims to examine the environmental impact of IR and highlight opportunities for transitioning to more sustainable practices within the IR suite. The environmental impact of IR is assessed in 3 critical domains: (1) energy consumption, (2) waste production, and (3) water pollution. For each domain, actionable strategies are proposed to mitigate environmental harm. Key actions include powering down equipment when not in use, utilizing energysaving modes, minimizing the reliance on single-use items where possible, collaborating with industry to reduce excessive packaging, and implementing recycling programs for waste and iodinated contrast media, along with incorporating environmental sustainability as a quality metric in the departments quality improvement program. Barriers to adopting environmentally sustainable changes include a lack of awareness, financial considerations, and the absence of government, institutional, and industry regulations. Leadership from professional societies and collaboration with industry partners will be essential for driving systemic change. However, individual departments can take action to foster a culture of environmental responsibility and implement sustainable practices.</p>","PeriodicalId":55290,"journal":{"name":"Canadian Association of Radiologists Journal-Journal De L Association Canadienne Des Radiologistes","volume":" ","pages":"8465371251326793"},"PeriodicalIF":2.9,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143712216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are currently no guidelines regarding optimal reporting structure for neuroradiological studies. Clear and efficient reports are essential to facilitating communication between healthcare providers. This project characterizes and compares preferred radiological reporting structures in neuroradiology among physicians. <b>Methods:</b> A REDCap survey including questions on practice environments, satisfaction with current reports, and preferences in report structures for 7 studies: MRI Lumbar Spine, MRI Sella, MRI Dementia, MRI Glioma, MRI Brain Metastases, CTA Head and Neck, and CT Unenhanced Brain was drafted and reviewed by radiologists. This anonymous survey collected responses from radiologists and physicians who read neuroradiology reports across the Greater Toronto Area. <b>Results:</b> The survey received 89 responses. Structured reports were preferred over free-text reports across all specialties for each study. Notably, a large proportion (37/44, 84.1%) preferred having structured reports for CTA head and neck. Preferences for MRI Brain Glioma were relatively mixed, with some respondents favouring free-text reports (8/24, 33.3%) and others preferring structured reports (13/24, 54.2%). Respondents preferring structured reports cited \"ease in finding information\" as the most common reason, while those favouring free-text reports chose \"fewer unnecessary sections\" most often. <b>Conclusion:</b> This study identifies opportunities to improve the organization and standardization of information in radiology reports.
