Objective: To evaluate the frequency and factors associated with clip migration in MRI-guided breast biopsies.

Methods: This study was approved by our Institutional Review Board and was compliant with HIPAA. We retrospectively evaluated all MRI-guided biopsies performed between January 2013 and December 2020 in our institution for clip migration.

Introduction: In the last two decades there has been a paradigm shift with breast conserving surgery (BCS) being applied to larger and more extensive breast malignancies. The aim of this study is to examine the success of BCS being performed in patients with extensive breast malignancies requiring at least 3 wires for localization, and to assess possible risk factors for failure.

Materials And Methods: We performed a retrospective single center review of 232 patients who underwent BCS between 2010 and 2020 requiring at least 3 wires for localization, thus comprising the multi-wire group (MWG).

Objectives: To assess the diagnostic performance of ultrafast magnetic resonance imaging (UF-DCE MRI) in differentiating benign from malignant breast lesions.

Materials And Methods: A comprehensive search was conducted until September 1, 2023, in Medline, Embase, and Cochrane databases. Clinical studies evaluating the diagnostic performance of UF-DCE MRI in breast lesion stratification were screened and included in the meta-analysis.

Objective: This study aims to determine whether persistent T1-weighted lesions signify a complete pathological response (pCR) in breast cancer patients treated with neoadjuvant chemotherapy and surgery, and to evaluate their correlation with imaging responses on MRI.

Materials And Methods: A retrospective review was conducted on data from breast cancer patients treated between January 2011 and December 2018. Patients who underwent breast MRI and pre- and post-neoadjuvant chemotherapy followed by surgery were included.

Background The diagnostic value of screening the contralateral breast with MRI in patients with newly diagnosed breast cancer is poorly understood. Purpose To assess the impact of MRI for screening the contralateral breast on long-term outcomes in patients with newly diagnosed breast cancer and to determine whether subgroups with unfavorable prognoses would benefit from MRI in terms of survival. Materials and Methods Data on consecutive patients with newly diagnosed breast cancer seen from January 2008 to December 2010 were reviewed retrospectively.

Purpose: To characterize the clinical, pathological, and imaging features of DCIS occult on conventional imaging diagnosed on MRI-guided biopsy associated with increased risk of invasive disease on surgical excision.

Materials And Methods: All consecutive patients with MRI-detected DCIS occult on conventional imaging between January 2009 and December 2018 were included. Women were divided into two groups based on final pathology: Pure DCIS or DCIS with invasive component.

Purpose: The goal of this study is to evaluate the frequency and imaging features of lobular neoplasia (LN) diagnosed on MRI-guided biopsy, determine the upgrade rate to malignancy, and assess for any features that may be associated with an upgrade on surgical excision.

Materials And Methods: Research ethical board approved the review of consecutive patients with MRI-detected LN between January 2009 and December 2018 with differentiation between pure LN and LN with associated other high-risk lesions. The final outcome was determined by final pathology results from surgical excision or 24 months of follow-up.

Objectives: To investigate the diagnostic accuracy of problem-solving breast magnetic resonance imaging (MRI) in excluding malignancy in a cohort of patients diagnosed with mammographic architectural distortion (MAD).

Methods: The Institutional Review Board approved the study. Imaging database with 40,245 breast MRIs done between January 2008 and September 2018 was retrospectively reviewed.

Purpose: There are no evidence-based guidelines for surveillance of women after bilateral mastectomy and reconstruction. Several societies recommend against routine breast imaging in this setting. Despite these recommendations, magnetic resonance imaging (MRI) is frequently used to follow these women.

Purpose: The study sought to investigate the role of breast magnetic resonance imaging (MRI) in patients diagnosed with atypical ductal hyperplasia (ADH) at core needle biopsy (CNB).

Methods: The breast MRI database at our centre was queried for studies performed between January 2010 and December 2016 for the clinical indication of ADH diagnosed at CNB. Medical files were reviewed for demographic data, clinical information, and radiology and pathology reports.

Background: Oncoplastic reconstruction is increasingly used in the management of women undergoing breast conserving surgery. We examined the findings on breast exam and imaging of patients who underwent breast conservation with or without oncoplastic reconstruction.

Objective: We hypothesized that patients undergoing immediate breast reconstruction would present with more palpable and imaging abnormalities compared to lumpectomy alone and undergo therefore more biopsies.

Purpose: With the increased use of breast ultrasound for different indications, sonographically abnormal axillary lymph nodes are not a rare finding. We examined clinical and imaging characteristics in correlation with pathological reports of the sonographic guided biopsies to assess the yield of needle biopsy of these nodes.

Methods: Clinical, imaging and pathology data were collected for 171 consecutive patients who underwent sonographic guided needle biopsy of an abnormal lymph node between 2008 and 2013.

Background: Preliminary reports suggest that a small left atrium (LA) is associated with severe acute pulmonary embolism (PE). This study used data derived from volumetric analyses of computed tomographic pulmonary angiography (CTPA) to investigate whether a reduced LA volume can predict adverse outcome in a large series of patients with acute PE.

Methods: We retrospectively analyzed 756 consecutive patients who received a diagnosis of acute PE by nongated CTPA between January 2007 and December 2010.
