Detection of occult liver metastases during EUS: Does the contrast make the difference?

We read with great interest the manuscript by Minaga et  al1 about the detection of liver metastases by contrast-enhanced harmonic EUS (CH-EUS) in patients with pancreatic cancer. The authors compared the accuracy in detecting left lobe liver metastases with contrast-enhanced CT scan (CE-CT) with fundamental B-mode EUS (FB-EUS) and CH-EUS in 426 patient s. The diagnostic accuracy of the 3 techniques was 90.6%, 93.4%, and 98.4%, respectively. Interestingly, CH-EUS was far superior to the other 2 techniques as far as small lesions (
