Methods: This was a retrospective, institutional review board{\textendash}approved study that collected data from 2 PET/CT departments. Dosimetry reports, correlated with the clinical schedules of the students, were normalized for workflow (amount of radioactivity), the number of technologists, and the number of monitored days in the department. A 2-sample t test assuming unequal variance with an α of 0.05 was used to compare doses between with-student and without-student groups and between direct-supervision and indirect-supervision groups. Results: The study consisted of a dataset of 42 dosimetry reports, 19 with students and 23 without students. When comparing with-student and without-student groups, the total (n = 42) extremity dose had a P value of 0.012 with a mean of 0.0011665 μSv/MBq/technologist/d; all other dose comparisons between groups were greater than 0.05 (P \> 0.05). For indirect supervision (n = 21), the extremity-dose P value was 0.298. The other dose P values were all less than 0.05. For direct supervision (n = 21), the dose P values were all greater than 0.05. There was a trend toward decreasing exposure of technologists when students were in the department. Conclusion: Extremity dose decreases when students are present. There is a trend toward decreasing dose with indirect supervision.}, issn = {0091-4916}, URL = {https://tech.snmjournals.org/content/48/3/214}, eprint = {https://tech.snmjournals.org/content/48/3/214.full.pdf}, journal = {Journal of Nuclear Medicine Technology} }
