PURPOSE: The purposes of this study are to (1) identify patterns of inpatient PET/computed tomography (CT) use in and outside of the USA and (2) characterize inpatient PET/CT use by location and indication.

MATERIALS AND METHODS: The study was deemed exempt by the Institutional Review Board. A survey link through REDCap was emailed to the Society of Nuclear Medicine and Molecular Imaging (SNMMI) members and PET Centers of Excellence members and posted on the SNMMI website. Data were collected from May 2018 to August 2018. Analyses were conducted using SAS Software 9.4 with the NPAR1WAY procedure. Differences were evaluated using the Kruskal-Wallis test with statistical significance defined as P ≤ 0.05.

RESULTS: A total of 124 people responded to the survey, 71.8% (89/124) in the USA, and 26.6% (33/124) outside the USA [1.6% (2/124) no response]. 81.5% (101/124) read inpatient PET/CTs. Median percent of inpatient PET/CTs was 8.0% (range 0-100). Use of inpatient PET/CT was different (P < 0.0001) in the USA (5%, range 0-80%) versus outside USA (17.7%, range 0-100%). Use of inpatient PET/CT was different by institution type: median percent of inpatient PET/CTs in community teaching hospitals was 4.5% (range 0-50) versus 1.1% (range 0-20) in community nonteaching, 10% (range 0-80) in academic medical centers, and 20.0% (range 6.3-40) in government-affiliated institutions (P = 0.0001).

CONCLUSIONS: Most US and non-US respondents read inpatients PET/CTs. Non-US respondents read a higher percentage of inpatient PET/CTs than US respondents. Respondents in government-affiliated institutions read the highest percent of inpatient PET/CTs and community nonteaching institutions the least. Results of this survey may help physicians evaluate whether their practice of providing inpatient PET/CT fits with current practice patterns.
