Methods and materials
This was a prospective study approved by the local research ethics committee,
University of Malaya,
and informed consent was obtained from all patients.
Patients referred to the Department of Biomedical Imaging,
University Malaya Medical Centre,
Malaysia for multi-phase computed tomography (CT) liver examinations from July 2012 to March 2013 were screened.
The patients were then divided into the following groups based on the CT findings: newly diagnosed hepatocellular carcinoma (HCC),
liver metastasis and control (patients with no focal liver lesion seen) (Refer Fig.
2).
Ultrasound and SWE were performed on these groups of patients using Aixplorer™ machine (SuperSonic Imagine,
Aix-en-Provence,
France) with liver scanning protocol.
Convex SC6-1 probe was used to acquire the baseline ultrasound B-mode images and to perform the elastography study.
Statistical analyses were performed with SPSS software (version 20.0,
IBM SPSS Statistics).
Two-sided statistical significance was defined as p < 0.05.
