Proper collimator selection is critical to obtaining high-quality, inter-pretable nuclear medicine images. 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.

Chronic functional gallbladder disorder, characterized by biliary pain in the absence of structural pathology, poses a diagnostic challenge necessitating reliable cholecystagogues for accurate evaluation. 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.
慢性功能性胆囊疾病的特点是在没有结构性病变的情况下出现胆道疼痛，这给诊断带来了挑战，需要可靠的胆囊刺激剂来进行准确评估。然而，合成胆囊收缩素类似物的经常性短缺促使人们开始探索替代药物。本文介绍了 Ensure Plus 作为肝胆闪烁成像的可行脂肪餐替代品在评估慢性功能性胆囊疾病方面的有效性。通过比较研究，在类似的患者群体中，安素可显示出与胆囊收缩素相当的诊断准确性。此外，Ensure Plus 还能显著改善胆囊射血分数异常患者胆囊切除术后的症状。本文提供了将 Ensure Plus 无缝整合到肝胆闪烁扫描中的详细方案，为临床医生提供了一种宝贵的工具，可用于解决胆囊收缩素短缺问题，同时保持慢性功能性胆囊疾病诊断的精确性。Ensure Plus 的使用不仅解决了供应方面的实际挑战，还凸显了其作为胆道诊断中一种经济、临床合理的替代品的潜力。

A 63-y-old woman with a history of breast cancer presented with concerns of osseous metastasis. Initial whole-body planar bone scintigraphy revealed a focus of concern overlying the sternum. SPECT/CT images revealed the anomaly — localized activity in the needleless hub attached to the chemotherapy port. If not for the precision of SPECT/CT, such a rare artifact could have led to a false-positive diagnosis, particularly impactful in breast cancer patients. This case emphasizes the critical role of SPECT/CT in accurate diagnoses.

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.

The radionuclide ventriculoperitoneal shunt evaluation study is a simple test that involves injecting a small volume of radionuclide into the shunt reservoir and then observing its disappearance using dynamic γ-camera imaging. Although it seems simple, there are several potential pitfalls that can result in a misinterpreted or uninterpretable study. This paper is a detailed description of how to avoid the pitfalls and also how to interpret the results.
