OBJECTIVE To evaluate the stiffness of the surrounding tissue of breast lesions using the strain ratio assessment method by ultrasound (US) elastography. METHODS This was an institutional ethics committee approved prospective study. A total of 127 breast lesions in 118 women (mean age 48.23 ± 14.32, range 20-90) were examined with conventional and(More)
OBJECTIVES To analyze the value of acoustic radiation force impulse imaging quantification in characterization of breast lesions and to analyze the stiffness of glandular and subcutaneous fatty tissue in benign and malignant lesions. METHODS A total of 175 breast lesions (67 malignant and 108 benign) in 173 women were studied. With acoustic radiation(More)
PURPOSE To analyze the diagnostic performance of shear wave elastography (SWE) in differentiating between benign and malignant breast lesions, with special emphasis on the value of the "stiff rim" sign, as compared with conventional ultrasonography (US). MATERIALS AND METHODS For this ethics committee-approved retrospective study, all patients provided(More)
OBJECTIVE To compare the diagnostic performance of the fat-to-lesion strain ratio (FLR) and gland-to-lesion strain ratio (GLR) in the diagnosis of breast lesions. METHODS This was an institutional ethics committee approved prospective study. One hundred and ninety-three breast lesions in 193 women (mean age, 46.03 ± 13.60 years, range 18-82 years) were(More)
To evaluate the efficacy and safety of percutaneous laser ablation (PLA) for unifocal T1N0M0 papillary thyroid microcarcinoma(PTMC). A retrospective study was conducted in 30 patients with single PTMC which was diagnosed by fine-needle aspiration biopsy (FNAB). PLA was performed for proper time to achieve adequate ablation zones. The extent of ablation was(More)
The goal of our study was to investigate the anisotropy of normal breast glandular and fatty tissue with acoustic radiation force impulse (ARFI) quantification. A total of 137 breasts in 137 women were enrolled. These breasts were divided into the duct-apparent group and the duct-inapparent group, divided into the ligament-apparent group and the(More)
The goal of this study was to verify the ultrasound features of hyper-echoic rims in thyroid nodules and to evaluate their diagnostic value in predicting thyroid malignancies. We retrospectively analyzed 228 pathologically proven thyroid nodules (137 malignant and 91 benign nodules). Forty-eight thyroid nodules had a hyper echogenic rim. All malignant(More)
During evolution the creation of single crossover chimeras between duplicated paralogous genes is a known process for increasing diversity. Comparing the properties of homologously recombined chimeras with one or two crossovers is also an efficient strategy for analyzing relationships between sequence variation and function. However, no well-developed in(More)
PURPOSE The purpose of this study was to sonographically evaluate the diagnosis of localized Castleman disease in the abdomen and pelvis. METHODS This was a retrospective analysis of 18 cases of Castleman disease localized in the abdomen and pelvis. The following features of the lesions were assessed on sonography (US): location, size, margin,(More)
The goal of our study was to investigate the value of color-coded Virtual Touch tissue imaging (VTI) using acoustic radiation force impulse (ARFI) technology in the characterization of breast lesions and to compare it with conventional ultrasound (US). Conventional US and color-coded VTI were performed in 196 solid breast lesions in 196 consecutive women(More)
