BACKGROUND Metaplastic carcinoma of the breast (MPCB) is a rare breast cancer. We reviewed sonographic findings for MPCB. METHODS Grayscale ultrasonography (US), color Doppler US (CDUS), and spectral Doppler US (SDUS) findings for 10 patients with MPCB breast were retrospectively reviewed. RESULTS The prevalence of MPCB was 3.9% among cases of breast(More)
OBJECTIVES This study aimed to report the differences in sonographic features of ruptured and unruptured epidermal cysts. METHODS We reviewed and analyzed the sonographic features of superficial epidermal cysts of in 2 subgroups of 46 patients: 20 with ruptured cysts and 26 with unruptured cysts. All lesions were diagnosed either by excisional biopsy or(More)
In recent studies, both tumor morphology and vascularity played an important role in differentiating breast tumors. In this article, a computer-aided diagnosis (CAD) system was proposed to quantify the tumor morphology of vascularity on three-dimensional (3-D) power Doppler breast ultrasound (PDUS) images. We segmented the tumor margin by the level set(More)
The review demonstrates the unique advantages of ultrasonography in pain control. Several imaging modalities can be used to guide pain control, such as computed tomography, magnetic resonance imaging, and radiography. Ultrasonography has unique advantages over these other modalities in terms of its non-ionizing radiation, real-time imaging, portability, and(More)
BACKGROUND The analgesic effect of xylocaine alone versus xylocaine with corticosteroid injection after ultrasonographically (US)-guided treatment of rotator cuff calcific tendonosis has not been described in English literature. The aim of this study was to compare the analgesic effect of xylocaine only with xylocaine and corticosteroid following US-guided(More)
A new method to fabricate an Au-rich interconnected ligament substrate by dealloying the Au-based metallic glass ribbon for surface-enhanced Raman scattering (SERS) applications was investigated in this study. Specifically, three substrates, Au film, Au-based metallic glass ribbon, and dealloyed Au-based metallic glass ribbon, were studied. The dealloyed(More)
BACKGROUND AND OBJECTIVES A computer-aided diagnosis (CAD) system based on the quantified color distributions in shear-wave elastography (SWE) was developed to evaluate the malignancies of breast tumors. METHODS For 57 benign and 31 malignant tumors, 18 SWE features were extracted from regions of interest (ROI), including the tumor and peritumoral areas.(More)
Synovial chondromatosis is a rare, benign, proliferative cartilaginous lesion arising from the synovial tissue, tenosynovium, or bursal lining. We describe the case of a patient who initially presented with multiple axillary masses. Breast ultrasound (US) was requested due to the concern of a breast tumor with axillary lymph node metastases. US study was(More)
BACKGROUND Thyroid cancer is the most prevalent endocrine malignancy, and the incidence of thyroid cancer has increased worldwide. Fine needle aspiration (FNA) for cytology of thyroid tissue is used for differentiating thyroid cancers from benign thyroid nodules. Overuse of FNA may detect subclinical thyroid cancer and play a role in the increased incidence(More)
BACKGROUND Ultrasound (US) elastography can provide information about the hardness of calcification and might help decide treatment strategy. The purpose of this study was to evaluate the hardness of the calcific area within rotator cuffs by US elastography as an aid for the selection of aspiration or fine-needle repeated puncture for the treatment of(More)
