Inpatient Imaging Utilization and Radiology Workload: Trends of the Past Decade and Through the COVID-19 Pandemic.
Article in Journal of the American College of Radiology : JACR, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe aim of this study was to assess inpatient radiology imaging utilization and workload trends at a large academic medical center from fiscal year (FY) 2013 to FY 2023.
methodsThis retrospective study included 896,005 imaging examinations from adult inpatients treated from October 1, 2012, to September 30, 2023 (FY 2013 to FY 2023) at an 866-bed tertiary care academic institution. Examinations were coded by modality-radiography (XR), CT, MRI, ultrasound, and nuclear medicine (NM)-and adjusted for disease severity using case-mix index. Relative value units (RVUs) were used to measure radiology workload. Linear regression analysis and the χ
resultsAlthough total number of annual imaging examinations increased from 102,025 to 118,991 during the study period (P < .001), total imaging examinations per CMAA decreased (P < .001) because of decreases in XR, ultrasound, and NM examinations (P < .001 for all). However, radiology workload (professional, technical, and global) increased significantly (P < .001), attributable mainly to increased CT and MRI utilization (P < .001). Although CT and MRI examinations per CMAA increased by 19.2% and 21.4% respectively, professional RVUs increased by 80.6% for CT (P < .001) and by 90.7% for MRI (P < .001). Average length of stay increased by 32.1% from 5.6 to 7.4 days (P < .001) during the study period.
conclusionsDespite an overall decrease in disease severity-adjusted inpatient imaging utilization, inpatient radiology workload increased significantly over the decade as advanced imaging replaced lower cost modalities. Greater reliance on CT and MRI, possibly influenced by coronavirus disease of 2019 practice changes and not fully explained by disease severity, was associated with longer inpatient stays.
