{"title":"Gender and Ethnicity Bias of Text-to-Image Generative Artificial Intelligence in Medical Imaging, Part 2: Analysis of DALL-E 3.","authors":"Geoffrey Currie, Johnathan Hewis, Elizabeth Hawk, Eric Rohren","doi":"10.2967/jnmt.124.268359","DOIUrl":"10.2967/jnmt.124.268359","url":null,"abstract":"<p><p>Disparity among gender and ethnicity remains an issue across medicine and health science. Only 26%-35% of trainee radiologists are female, despite more than 50% of medical students' being female. Similar gender disparities are evident across the medical imaging professions. Generative artificial intelligence text-to-image production could reinforce or amplify gender biases. <b>Methods:</b> In March 2024, DALL-E 3 was utilized via GPT-4 to generate a series of individual and group images of medical imaging professionals: radiologist, nuclear medicine physician, radiographer, nuclear medicine technologist, medical physicist, radiopharmacist, and medical imaging nurse. Multiple iterations of images were generated using a variety of prompts. Collectively, 120 images were produced for evaluation of 524 characters. All images were independently analyzed by 3 expert reviewers from medical imaging professions for apparent gender and skin tone. <b>Results:</b> Collectively (individual and group images), 57.4% (<i>n</i> = 301) of medical imaging professionals were depicted as male, 42.4% (<i>n</i> = 222) as female, and 91.2% (<i>n</i> = 478) as having a light skin tone. The male gender representation was 65% for radiologists, 62% for nuclear medicine physicians, 52% for radiographers, 56% for nuclear medicine technologists, 62% for medical physicists, 53% for radiopharmacists, and 26% for medical imaging nurses. For all professions, this overrepresents men compared with women. There was no representation of persons with a disability. <b>Conclusion:</b> This evaluation reveals a significant overrepresentation of the male gender associated with generative artificial intelligence text-to-image production using DALL-E 3 across the medical imaging professions. Generated images have a disproportionately high representation of white men, which is not representative of the diversity of the medical imaging professions.</p>","PeriodicalId":16548,"journal":{"name":"Journal of nuclear medicine technology","volume":" ","pages":"162-168"},"PeriodicalIF":1.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142502306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In patients with established CS, serial ¹⁸F-FDG PET can be used to assess response to immunosuppressive therapy and long-term surveillance for reactivation of myocardial inflammation in patients with low-grade or quiescent disease. Patient preparation before ¹⁸F-FDG PET scanning is key in ensuring adequate suppression of physiologic myocardial ¹⁸F-FDG uptake, to maximize the power of the test to detect pathology. Inadequate dietary preparation can cause diffuse or focal-on-diffuse ¹⁸F-FDG uptake in the absence of active inflammation. It is important to assess resting myocardial perfusion, typically with ⁸²Rb cardiac PET. Several different patterns of abnormalities have been reported in patients with CS, including normal myocardial perfusion with focal or patchy ¹⁸F-FDG uptake suggesting myocardial inflammation without scarring; the presence of a myocardial perfusion defect with abnormal ¹⁸F-FDG uptake suggesting myocardial scarring with inflammation; and the presence of a myocardial perfusion defect without ¹⁸F-FDG uptake indicating myocardial scarring without inflammation. Prognostically, the presence of myocardial perfusion defects and abnormal ¹⁸F-FDG uptake has been shown to be an independent predictor of death or ventricular arrythmias. A high myocardial SUV_max in the left and right ventricles has been shown to be an independent predictor of adverse clinical outcomes. Although the diagnostic performance of ¹⁸F-FDG PET has been studied, the reference standard for CS tended to rely on clinical criteria, which may be less sensitive than ¹⁸F-FDG PET at detecting CS. Therefore, the diagnosis of CS should rely on a multidisciplinary team approach involving multimodality advanced imaging, including echocardiography, cardiovascular MR, and ¹⁸F-FDG PET.</p>","PeriodicalId":16548,"journal":{"name":"Journal of nuclear medicine technology","volume":" ","pages":"123-129"},"PeriodicalIF":1.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143255821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the field experiences exponential growth, driven by the surge in approvals of radiopharmaceuticals for diagnostic and therapeutic applications, it becomes vital to delve into the delivery methods of radiopharmaceuticals. Health care professionals take precautions during radiopharmaceutical administration, including maintaining distance from radioactive sources, using shielding, limiting exposure time, and monitoring radiation levels with badges. Regular evaluations provide compliance with recommended exposure limits, yet concerns persist, especially regarding the cumulative radiation exposure from manual injections over time. Understanding the long-term effects of radiation exposure has spurred the development of cutting-edge medical device technologies, such as autoinjectors, designed to administer radiopharmaceuticals accurately while minimizing total radiation dose to health care professionals. The U.S. Pharmacopeia 825 regulation refers to these devices as \"direct infusion systems.\" Nuclear medicine technologists commonly refer to them as \"autoinjectors,\" whereas device manufacturers may use terms such as injection system, radiopharmaceutical injector, or infusion system. Despite variations in terminology, these devices hold a pivotal role in shaping the future of radiopharmaceutical delivery. In an era of escalating demand for PET procedures worldwide, skilled health care professionals ensure the safe and precise dosing of radiopharmaceuticals.
