Sunday, November 28 | 12:05 p.m.-12:15 p.m. | SSA21-09 | Room S504ABIn this scientific session, a team from Kumamoto University in Kumamoto, Japan, will discuss the benefits of computer-aided detection (CAD) in contrast-enhanced ultrasound (CEUS) of focal liver lesions.
Believing that CAD can compensate for the operator dependence of ultrasound, the researchers performed an observer study to demonstrate its potential in the differential diagnosis of liver lesions on CEUS, according to presenter Junji Shiraishi, PhD.
The researchers tested their CAD technique on a dataset of 107 focal liver lesions from 107 cases. Seven radiologists read the dynamic CEUS images first without and then with CAD.
The study team found that CAD yielded an overall sensitivity of 76.6%. It also significantly improved the diagnostic performance of the radiologists.
Co-author Katsutoshi Sugimoto, MD, will also present the research team's findings during a multisession course on Monday (9:15 a.m.-9:25 a.m., VG21-04, Room E353A).
