Recall patterns and risk of primary liver cancer for subcentimeter ultrasound liver observations: a multicenter study

Abstract

Recall patterns for patients with subcentimeter liver lesions on ultrasound varied widely. The low risk of PLC in these patients supports short-interval ultrasound in 3-6 months, although diagnostic CT/MRI may be warranted for high-risk subgroups such as those with elevated alpha-fetoprotein levels.
