Collimators help eliminate scatter, which leads to poor spatial resolution and blurry images. We present the case of a posttherapy 177 Lu-DOTATATE (Lutathera) patient who was initially imaged with a low-energy, high-resolution collimator routinely used in 99m Tc imaging. On image review, the patient was reimaged with the appropriate medium-energy, high-resolution collimator, which resulted in improved image quality. When reviewing the quality of images, it is important to understand modi fi cations to the imaging that can signi fi cantly improve image quality and interpretation.","PeriodicalId":16548,"journal":{"name":"Journal of nuclear medicine technology","volume":"151 S301","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139006438","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}

However, recurrent shortages of synthetic cholecystokinin analogs have prompted the exploration of alternative agents. This paper describes the ef fi cacy of Ensure Plus as a viable fatty meal substitute for hepatobiliary scintigraphy in assessing chronic functional gall-bladder disorder. Through comparative studies, Ensure Plus demonstrates comparable diagnostic accuracy to cholecystokinin in similar patient populations. Furthermore, Ensure Plus demonstrates signi fi - cant symptom improvement after cholecystectomy in patients with anomalous gallbladder ejection fractions. This paper offers a detailed protocol for the seamless integration of Ensure Plus into hepatobiliary scintigraphy, providing clinicians with a valuable tool to navigate cholecystokinin shortages while maintaining diagnostic precision in cases of chronic functional gallbladder disorder. The use of Ensure Plus not only addresses practical supply challenges but also underscores its potential as a cost-effective and clinically sound alternative in biliary diagnostics.","PeriodicalId":16548,"journal":{"name":"Journal of nuclear medicine technology","volume":"11 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139003413","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}

{"title":"An International Survey Investigating the Incidence and Management of Brown Fat Uptake on18F-FDG PET/CT at Children’s Hospitals and Interventions for Mitigation","authors":"William C. Gaylord, Andrew T. Trout, Anthony N. Audino, Jennifer A. Belsky","doi":"10.2967/jnmt.123.266536","DOIUrl":"https://doi.org/10.2967/jnmt.123.266536","url":null,"abstract":"Brown fat can present challenges in patients with cancer who undergo 18 F-FDG PET scans. Uptake of 18 F-FDG by brown fat can obscure or appear similar to active oncologic lesions, causing clinical challenges in PET interpretation. Small, retrospective studies have reported environmental and pharmacologic interventions for suppressing brown fat uptake on PET; however, there is no clear consensus on best practices. We sought to characterize practice patterns for strategies to mitigate brown fat uptake of 18 F-FDG during PET scanning. Methods: A survey was developed and distributed via e-mail LISTSERV to members of the Children ’ s Oncology Group diagnostic imaging committee, the Society for Nuclear Medicine and Molecular Imaging pediatric imaging council, and the Society of Chiefs of Radiology at Children ’ s Hospitals between April 2022 and February 2023. Responses were stored anony-mously in REDCap, aggregated, and summarized using descriptive statistics. Results: Fifty-fi ve complete responses were submitted: 51 (93%) faculty and fellow-level physicians, 2 (4%) technologists, and 2 (4%) respondents not reporting their rank. There were 43 unique institutions represented, including 5 (12%) outside the United States. Thirty-eight of 41 (93%) institutions that responded on environmental interventions reported using warm blankets in the infusion and scanning rooms. Less than a third ( n 5 13, 30%) of institutions reported use of a pharmacologic intervention, with propranolol ( n 5 5, 38%) being most common, followed by fentanyl ( n 5 4, 31%), diazepam ( n 5 2, 15%), and diazepam plus pro-pranolol ( n 5 2, 15%). Selection criteria for pharmacologic intervention varied, with the most common criterion being brown fat uptake on a prior scan ( n 5 6, 45%). Conclusion: Clinical practices to mitigate brown fat uptake on pediatric 18 F-FDG PET vary widely. Simple environmental interventions including warm blan-kets or increasing the temperature of the injection and scanning rooms were not universally reported. Less than a third of institutions use pharmacologic agents for brown fat mitigation.","PeriodicalId":16548,"journal":{"name":"Journal of nuclear medicine technology","volume":"128 3","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139004380","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}
