OBJECTIVE We wanted to evaluate the role of diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) for detecting breast tumors, as compared with the T1- and T2-weighted images. MATERIALS AND METHODS Forty-one female patients underwent breast MRI, and this included the T1-, T2-, DWI and dynamic contrast-enhanced images. Sixty-five(More)
PURPOSE To evaluate the role of diffusion-weighted imaging (DWI) in the detection of breast cancers, and to correlate the apparent diffusion coefficient (ADC) value with prognostic factors. MATERIALS AND METHODS Sixty-seven women with invasive cancer underwent breast MRI. Histological specimens were analyzed for tumor size and grade, and expression of(More)
OBJECTIVE To evaluate the mammographic and sonographic findings of pregnancy-associated breast cancer. METHODS A total of 22 consecutive patients with breast cancer pathologically diagnosed during pregnancy (n = 10) or lactation (n = 12) were included in this study. The ages of the patients ranged from 26 to 49 years. Both mammography and sonography were(More)
Despite the fact that mammography has been the golden standard in breast cancer detection for several decades, its sensitivity decreases for women with dense breast tissue, which happens to be common in Korea. As an alternative, breast ultrasonography can be effective diagnostic modalities that complement the defect of mammography. Recently, breast-specific(More)
The aim of this study was to evaluate the imaging findings of invasive lobular carcinoma (ILC) compared to those of invasive ductal carcinoma (IDC). The study included ILCs (n = 27) and IDCs (n = 85). Imaging findings were retrospectively evaluated, according to the BI-RADS lexicon. We compared the imaging findings, multiplicity, and magnetic resonance(More)
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)
The aims of this study are to demonstrate the clinical characteristics and various imaging findings of breast cancers in patients with interstitial mammoplasty. A total of six patients, who had breast cancer and had received liquid silicone or paraffin injection for augmentation, were included in this study. Mammography, ultrasonography, dynamic breast MRI,(More)
BACKGROUND To evaluate the location of tumor relapse and imaging modality for detection according to the breast cancer subtype: luminal A, luminal B, HER2 positive luminal B, nonluminal HER2 positive, and triple negative. MATERIALS AND METHODS A total of 1244 patients with breast cancer with known estrogen receptor (ER), progesterone receptor (PR), Ki-67(More)
UNLABELLED PURPOSE AND MATERIAL AND METHODS: MR findings of 9 surgically proven tubo-ovarian abscesses were analyzed in 8 patients. The images were evaluated for signal intensity characteristics and morphologic appearance of the mass, and presence of secondary changes in adjacent pelvic organs and structures. RESULTS The signal intensity of the lesions on(More)
Ultrasound (US) elastography is a valuable imaging technique for tissue characterization. Two main types of elastography, strain and shear-wave, are commonly used to image breast tissue. The use of elastography is expected to increase, particularly with the increased use of US for breast screening. Recently, the US elastographic features of breast masses(More)
