Randomized trial assesses growth in abdominal imaging across patient classes, highlighting acute care needs.

This study aims to evaluate trends in abdominal imaging utilization across a large healthcare system over a decade.
Data from CT, US, and MRI examinations from January 2014 to December 2023 were analyzed.
Poisson regression analysis was employed to model examination trends by modality and patient class.
The study examined the relative distribution of exams among emergency department patients, inpatients, and outpatients.
Total of 3,408,471 imaging studies performed in 1,150,921 patients.
ED patient imaging increased by 15.9% annually, surpassing inpatient (14.6%) and outpatient (10.5%) increases.
The proportion of acute care cases rose from 41.7% in 2014 to 52% in 2023.

Handwork et al. (2026) studied this question.
