Abstract
Transabdominal ultrasonography, contrast-enhanced computed tomography, and magnetic
resonance imaging (MRI) are the common diagnostic tests for the detection of hepatic
lesions. Use of enhanced and advanced MRI technique, that is, diffusion weighted MRI
and hepatocyte-specific contrast agents, has further improved the accuracy of detection
of metastatic liver lesions ≤ 10 mm in diameter. However, even with these advanced
imaging modalities sensitivity is low for lesions smaller than 10 mm when compared
with standard intraoperative ultrasound. Endoscopic ultrasound (EUS) is an emerging
imaging modality with resolution sufficient to detect and sample lesions as small
as 5 mm in diameter. In this news and views, we have discussed the role of standard
and enhanced EUS for the detection of metastatic liver lesions.
