Abstract
Background: Identifying patients in whom ultrasound may be inadequate to exclude the presence of hepatocellular carcinoma (HCC) can inform interventions to improve screening effectiveness.
Aim: Characterize correlates of suboptimal ultrasound quality and changes in ultrasound quality over time in patients with cirrhosis undergoing HCC screening.
Methods: We performed a retrospective cohort study of patients with cirrhosis who underwent ultrasound examination at two large health systems between July 2016 and July 2019. Exam adequacy was graded by radiologists using the LI-RADS Visualization Score (A, B, C); we evaluated changes in visualization over time among patients with >1 ultrasound exam. We performed multivariable logistic regression to identify characteristics associated with limited ultrasound visualization (scores B or C).
Results: Of 2,053 cirrhosis patients, 1,685 (82.1%) had ultrasounds with score A, 262 (12.8%) score B, and 106 (5.2%) score C. Limited visualization was associated with alcohol-related or NAFLD cirrhosis and presence of class II-III obesity. Among 1,546 patients with >1 ultrasound, 1,129 (73.0%) had the same visualization score on follow-up (1,046 score A, 60 score B, 23 score C). However, 255 (19.6%) of 1,301 with score A at baseline had limited visualization when repeated (230 score B, 25 score C), and 130 (53.1%) of 245 patients with baseline limited visualization had good visualization when repeated.
Conclusions: Nearly one in five patients with cirrhosis had moderately-severely limited ultrasound visualization for HCC nodules, particularly those with obesity or alcohol-related or NAFLD cirrhosis. Ultrasound quality can change between exams, including improvement in many patients with limited visualization.
