Impact of real-time virtual sonography, a coordinated sonography and MRI system that uses an image fusion technique, on the sonographic evaluation of MRI-detected lesions of the breast in second-look sonography.

摘要: The aim of this study was to verify the utility second-look sonography using real-time virtual (RVS)—a coordinated with an MRI system that uses image fusion technique magnetic navigation—on sonographic evaluation MRI-detected lesions breast. Of 196 consecutive patients who were examined breast in our hospital from 2006 2009, those underwent identify enrolled study. performed a 1.5-T imager patient supine position. To assess efficacy benefits RVS, correlations between lesion detection rates, features, distribution, and histopathological classification on conventional B-mode or RVS analyzed. patients, 55 (28 %) demonstrated 67 initially detected by MRI, followed sonography. lesions, 18 (30 %) identified alone, whereas 60 (90 %) (p < 0.001). rates 16 focal 46 mass sized <5 mm, 45 5–10 mm, 26 situated within mammary gland, 41 around fascia, 24 malignant 43 benign were, respectively, 25, 26, 24, 42, 17, 33, 23 % B-mode, significantly higher, at 94, 89, 88, 90, 92, 88 % RVS. seven no correlates, five could be biopsied marking information onto body surface Overall, 65 (97 %) confirmed results. Our results suggest additional use increases rate without operator dependence.
