Most breast cancers (81%) detected at screening US were not seen at mammography, even in retrospect. In addition, 19% had subtle or evident findings missed at mammography.

Purpose To investigate whether pretreatment breast magnetic resonance (MR) imaging features are associated with pathologic complete response (PCR) and recurrence-free survival after neoadjuvant chemotherapy (NAC) in patients with triple-negative breast cancer. Materials and Methods Identified were 132 patients with primary triple-negative breast cancers who underwent NAC and pretreatment MR imaging between 2004 and 2010. Three breast radiologists independently reviewed the MR images based on the

BACKGROUND: Breast cancer is a heterogeneous disease with intrinsic molecular subtypes. The different biology and histology of breast cancer exhibit different tumor morphology at breast magnetic resonance imaging (MRI). However, few studies have examined the quantitative relationship between the MRI morphological and immunohistochemical features in breast cancer. PURPOSE: To investigate the correlations between tumor roundness, as quantitatively assessed with MRI and biomarkers or subtypes of br

PURPOSE: To determine the imaging and clinical-pathologic factors associated with recurrence in patients with early stage triple-negative breast cancer. MATERIALS AND METHODS: This study was approved by the institutional review board, and the requirement to obtain informed consent was waived. The authors evaluated 398 patients with stage I or II triple-negative breast cancer (median age, 48 years; range, 21-81 years) who were treated between January 2003 and December 2008. Data collected include

Background Most patients with early-stage breast cancer have clinically negative lymph nodes (LNs). However, 15-20% of patients have axillary nodal metastasis based on the sentinel LN biopsy. Purpose To assess whether ultrasound (US) features of a primary tumor are associated with axillary LN metastasis in patients with clinical T1-T2N0 breast cancer. Material and Methods This retrospective study included 138 consecutive patients (median age = 51 years; age range = 27-78 years) who underwent bre

Screening ultrasound (US) can increase the detection of breast cancer. However, little is known about the clinicopathologic characteristics of breast cancers detected by screening US. A search of the database for patients with breast cancer yielded a dataset in 6837 women who underwent breast surgery at Seoul National University Hospital (Korea). Of 6837 women, 1047 were asymptomatic and had a non-palpable cancer. Two hundred fifty-four women with 256 cancers detected by US (US-detected cancer)

Rhinocerebral mucormycosis is an acute fulminant opportunistic fungal infection usually seen in diabetic or immunocompromised patients. The fungi that cause mucormycosis inoculate the nasal mucosa and may spread to the paranasal sinuses, orbit, and brain. Our patient initially presented with mild ethmoid sinusitis. At that time, brain MRI and contrast-enhanced MR angiography were grossly normal. However, aggravation of sinusitis with extension to the right orbit and anterior cranial fossa rapidl

Purpose To determine additional cancer yield of magnetic resonance (MR) imaging in women with breast cancer detected at screening ultrasonography (US) and to identify a subgroup of women who are likely to benefit from preoperative MR imaging. Materials and Methods This study was approved by the institutional review board, and the requirement for informed consent was waived. A retrospective review of 374 women (median age, 48 years; age range, 30-74 years) with breast cancer detected at screening

Abstract Objective To determine survival outcomes in women with breast cancer detected at combined screening with breast MRI and mammography versus screening mammography alone. Methods This is an institutional review board-approved retrospective study, and the need for informed consent was waived. A total of 3002 women with an increased risk of breast cancer were screened between 2001 and 2004. Of the 3002 women, 1534 (51.1%) had 2780 combined screenings (MRI and mammography) and 1468 (48.9%) ha

Background Locoregional recurrence (LRR) following breast conservation therapy (BCT) is associated with an increased risk of distant metastasis and death in patients with breast cancer. Purpose To investigate whether preoperative breast magnetic resonance imaging (MRI) features are associated with the risk of LRR in patients undergoing BCT. Material and Methods A total of 3781 women with primary invasive breast cancer underwent preoperative MRI and BCT between 2003 and 2013. Forty-eight patients

OBJECTIVE: The objective of our study was to determine the cancer yield of preoperative breast MRI in women with newly diagnosed ductal carcinoma in situ (DCIS) and to identify subgroups of DCIS patients for whom MRI is more likely to identify additional cancers. MATERIALS AND METHODS: A database search for patients with DCIS who had undergone breast surgery between 2007 and 2011 was performed. A total of 308 women (median age, 49 years; range, 25-82 years) with DCIS underwent mammography, sonog
