OBJECTIVE The aim of this study was to evaluate the value of breast-specific gamma imaging (BSGI) as compared with mammography (MMG) and ultrasonography (US). METHODS This study retrospectively enrolled 121 women with breast cancer (45.0 ± 8.1 years) and dense breasts (breast density >50 %). All patients underwent preoperative BSGI, MMG, and US, and the(More)
A 63-year-old woman was referred to a breast surgeon with a breast mass discovered incidentally during follow-up study after colon cancer surgery. Invasive adenocarcinoma was revealed on core needle biopsy. Wide excision of the breast including the tumor was performed. On standard histological examination the tumor showed features of moderately(More)
We investigate the current status of endoscopic thyroidectomy in Korea. A representative questionnaire was sent to 21 members of the Korean Association of Endocrine Surgeons who were thought to be performing endoscopic thyroidectomy. All the reply letters were collected and analyzed. The response rate was 95%. A total of 1616 cases of endoscopic(More)
Secretory carcinoma of the breast is a rare but histologically distinct variant of invasive ductal carcinoma that has an indolent growth pattern and a more favorable prognosis than that of typical ductal carcinoma. We present the imaging and histopathologic findings of a case of this tumor that initially manifested as a palpable mass in the left breast of a(More)
PURPOSE To observe long-term clinical outcomes for patients with early-stage breast cancer treated with forward intensity-modulated radiation therapy (IMRT), including local control and clinical toxicities. MATERIALS AND METHODS We retrospectively analyzed a total of 214 patients with stage I-II breast cancer who were treated with breast conserving(More)

When the fast Fourier transform (FFT) is executed using an in-place method, the input or output data must be accessed in a digit-reversed order. The previous digit reversal circuits, which are based on a binary counter, require complex multiplexers. This paper proposes a new digit reversal circuit based on two-bit counter modules for the variable-length(More)
This paper proposes a simplified simultaneous multithreading (SMT) architecture aiming at CPU cores of embedded SoCs for consumer applications. This architecture reduces the hardware cost and design complexity of the SMT architecture by adopting in-order execution within threads and static resource partitioning among threads. In our architecture, processor(More)
BACKGROUND The excision of breast lesions using an ultrasound-guided vacuum-assisted biopsy device (VABD) is a widely used technique for the diagnosis and treatment of breast disease, but the results of long-term follow-up after VABD excision of benign breast tumours have not been reported. The purpose of this study was to evaluate the results of long-term(More)
