Objectives: Differences in the process of using liver imaging technologies
might be important to patients. This study aimed to investigate preferences for scanning
modalities used in diagnosing focal liver lesions.Methods: A discrete choice experiment was administered to 504 adults aged
≥25 years. Respondents made repeated choices between two hypothetical scans, described
according to waiting time for scan and results, procedure type, the chance of minor
side-effects, and whether further scanning procedures were likely to be required. Choice
data were analyzed using mixed-logit models with respondent characteristics used to
explain preference heterogeneity.Results: Respondents preferred shorter waiting times, the procedure to be
undertaken with a handheld scanner on a couch instead of within a body scanner, no
side-effects, and no follow‑up scans (p ≤ .01). The average respondent
was willing to wait an additional 2 weeks for the scan if it resulted in avoiding
side-effects, 1.5 weeks to avoid further procedures or to be told the results immediately,
and 1 week to have the scan performed on a couch with a handheld scanner. However,
substantial heterogeneity was observed in the strength of preference for desirable imaging
characteristics.Conclusions: An average individual belonging to a general population
sub‑group most likely to require imaging to characterize focal liver lesions in the United
Kingdom would prefer contrast‑enhanced ultrasound over magnetic resonance imaging or
computed tomography. Insights into the patient perspective around differential
characteristics of imaging modalities have the potential to be used to guide
recommendations around the use of these technologies.
