Myoid hamartoma is an uncommon type of breast hamartoma and its recurrence is very rare. We report the imaging appearance of an unusual case of recurrent myoid hamartoma of the breast mimicking malignancy in a 43-year-old woman. Although the mammographic and ultrasonographic findings have long been described in the literature, MR finding with a dynamic(More)
OBJECTIVE We describe typical sonography characteristics of locally recurrent tumors after thyroidectomy for thyroid cancer and the benign conditions mimicking tumor recurrence, with an emphasis on the differential diagnosis. CONCLUSION Ultrasound is an effective imaging technique not only for the detection of locally recurrent tumors but also for the(More)
PURPOSE The aim of this study was to evaluate the performance of a proposed computer-aided detection (CAD) system in automated breast ultrasonography (ABUS). METHODS Eighty-nine two-dimensional images (20 cysts, 42 benign lesions, and 27 malignant lesions) were obtained from 47 patients who underwent ABUS (ACUSON S2000). After boundary detection and(More)
The purpose of our study was to evaluate the ultrasound features of suture granulomas at the thyroid bed after thyroidectomy for papillary thyroid carcinoma with an emphasis on their differentiation from locally recurrent thyroid carcinomas. We enrolled 14 suture granulomas in 10 patients and 20 locally recurrent carcinomas in 18 patients after(More)
OBJECTIVE The objective of our study was to retrospectively determine the positive predictive value of each descriptor and of combined descriptors for microcalcifications to predict the risk of malignancy as well as the appropriate final assessment category. MATERIALS AND METHODS A total of 308 needle-localized open breast biopsies for mammographically(More)
PURPOSE We evaluated the impact of three automatic optimization of parameters (AOP) modes of digital mammography on the dose and image quality. METHODS Computerized Imaging Reference Systems phantoms were used. A total of 12 phantoms with different thickness and glandularity were imaged. We analyzed the average glandular dose (AGD) and entrance surface(More)
OBJECTIVE The objective of our study was to prospectively evaluate the diagnostic accuracy of optical diffusion breast imaging in patients who underwent conventional ultrasound followed by surgery or biopsy. SUBJECTS AND METHODS We performed optical diffusion breast imaging after conventional ultrasound of 193 patients (mean age, 47 years) with 217(More)
PURPOSE We investigated whether the preoperative ultrasound (US)-guided hookwire localization for nonpalpable cervical masses allows surgeons to find these masses more easily and more confidently. METHODS Eight patients underwent preoperative US-guided hookwire insertion for nonpalpable cervical masses at our institution between January 2008 and January(More)
