Ordered-subset expectation maximization iterative reconstruction with resolution recovery, scatter, and attenuation correction was used, and the optimal collimator was determined on the basis of the contrast-to-noise ratio (CNR), percentage contrast, and specific binding ratio. The acquisition time that could be reduced using the optimal collimator was determined. The optimal collimator was used to retrospectively evaluate diagnostic accuracy via receiver-operating-characteristic analysis and specific binding ratios for 41 consecutive patients who underwent DAT-SPECT. <b>Results:</b> When the collimators were compared in the phantom verification, the CNR and percentage contrast were significantly higher for the MEHRS collimator than for the wide-energy high-resolution collimator (<i>P</i> < 0.05). There was no significant difference in the CNR between 30 and 15 min of imaging time using the MEHRS collimator. In the clinical study, the areas under the curve for acquisition times of 30 and 15 min were 0.927 and 0.906, respectively, and the diagnostic accuracies of the DAT-SPECT images did not significantly differ between the 2 times. <b>Conclusion:</b> The MEHRS collimator provided the best results for DAT-SPECT with C-SPECT; shorter acquisition times (<15 min) may be possible with injected activity of 167-186 MBq.</p>","PeriodicalId":16548,"journal":{"name":"Journal of nuclear medicine technology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10538243","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}

Gathering with nuclear medicine professionals from around the world to share new ideas, technologies, and information is always an exhilarating experience, and this year was no exception. Although the haze and smoke from the Canadian fires darkened the city skies, nothing could darken the mood of those attending the meeting, either virtually or in person. There was something for everyone, including the festive opening ceremony, the very competitive knowledge bowl, the packed educational opportunities, the many social events, the informative and educational exhibit hall, and the new ‘virtual’ poster hall, not to mention the many networking opportunities! A great social and educational time was had by all! During the educational program, Mary Beth Farrell, JNMT’s CE Editor, presented “How to Write a Manuscript” to students and attending nuclear medicine professionals, designed to provide and encourage future authors with the tools to write successfully. JNMT is always looking for new content and new authors! I followed with a very brief summary of the publication process once the manuscript is submitted. For authors new to the publication process, we stressed the fact that help is available and emphasized that, aside from the prestige and bragging rights of being published, there also may be financial rewards associated with being published! For those not quite ready to put pen to paper, ok, so I’m “old school”—how about fingers to the keyboard—we encouraged becoming a reviewer. Every nuclear medicine professional is an expert in some aspect of nuclear medicine. Why not consider becoming a reviewer of manuscripts specific to that expertise? The process is easy and begins by creating an account on the SNMMI publication portal at JNM Manuscript Processing System (snmjournals.org). Turning to this issue, a diverse collection of continuing education articles is offered. Dual-energy x-ray absorptiometry (DXA) units replaced dual-energy photon absorptiometry (DPA) units in the late 1980s; however, many nuclear medicine departments continue to perform DXA procedures today. Banks et al. present Part 1 of a two-part series that summarizes bone physiology, osteoporosis etiology, and the principles and technical aspects of DXA (1). Part 2 will follow in the December issue with a review of DXA interpretation as well as potential scanning pitfalls and techniques to improve image quality. Practice guidelines support best practice in the clinical setting. The Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the European Association of Nuclear Medicine (EANM) routinely review and update guidelines for imaging and therapeutic nuclear medicine procedures to improve the quality of service for patients worldwide. The updated practice guideline for the treatment of palliation of bone pain provides the latest information on the therapeutic use of available ","PeriodicalId":16548,"journal":{"name":"Journal of nuclear medicine technology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1142/9789812565846_0003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45834169","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}

The GPT 3.5-powered ChatGPT chatbot released in late November 2022 has emerged as an immediate threat to academic and scientific writing. <b>Methods:</b> Both examinations and written assignments for nuclear medicine courses were tested using ChatGPT. Included was a mix of core theory subjects offered in the second and third years of the nuclear medicine science course. Long-answer-style questions (8 subjects) and calculation-style questions (2 subjects) were included for examinations. ChatGPT was also used to produce responses to authentic writing tasks (6 subjects). ChatGPT responses were evaluated by Turnitin plagiarism-detection software for similarity and artificial intelligence scores, scored against standardized rubrics, and compared with the mean performance of student cohorts. <b>Results:</b> ChatGPT powered by GPT 3.5 performed poorly in the 2 calculation examinations (overall, 31.7% compared with 67.3% for students), with particularly poor performance in complex-style questions. ChatGPT failed each of 6 written tasks (overall, 38.9% compared with 67.2% for students), with worsening performance corresponding to increasing writing and research expectations in the third year. In the 8 examinations, ChatGPT performed better than students for general or early subjects but poorly for advanced and specific subjects (overall, 51% compared with 57.4% for students). <b>Conclusion:</b> Although ChatGPT poses a risk to academic integrity, its usefulness as a cheating tool can be constrained by higher-order taxonomies. Unfortunately, the constraints to higher-order learning and skill development also undermine potential applications of ChatGPT for enhancing learning.
