Nodules of non-hypervascular and low signal intensity during hepatobiliary phase (NLH nodules) detected by gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI), also known as hypovascular hypointense nodules, is important MR features that indicate the hepatocellular carcinoma (HCC) development in the future. The presence of NLH nodules is known as at high risk of HCC development in the liver. Hence, we hypothesized that NLH nodules can be also a risk of recurrence after surgical resection of HCCs. We evaluated the prognostic value of NLH nodules in patients with HCC. Presence of NLH nodules is at high risk of multicentric recurrence after hepatectomy.
