Real-time spatial compound imaging in breast ultrasound
2002
Abstract To determine the role of real-time spatial compound imaging in breast ultrasound (US), 38 patients with a total of 50 benign changes (fibroadenomas, cysts, lactiferous duct dilatation) underwent both conventional B-mode US and real-time spatial compound imaging under standardized examination settings. Subsequently, images were reviewed independently by three readers experienced in breast US and evaluated according to a multistage scoring system with regard to the presence of artefacts, delineation of boundaries and depiction of internal structures. With significant reader concordance, real-time spatial compound imaging was found to produce speckle reduction with improvement of tissue differentiation, increased conspicuity of low-contrast lesions, enhanced delineation of capsular margins and ducts, and improved depiction of internal architecture of solid lesions, as well as clearer visualization of cystic contents due to clutter reduction. Preservation of central acoustic enhancement and lateral edge shadowing in cysts and fibroadenomas, however, was recorded better in conventional imaging. (E-mail:s.pankl@telering.at)
