To evaluate the potential of diffusion-weighted (DW) magnetic resonance (MR) imaging with an apparent diffusion coefficient (ADC) map in prediction response to neoadjuvant chemotherapy patients breast cancer.This retrospective study was approved by institutional review board, which waived informed consent requirement. Fifty-three consecutive women (mean age, 43.7 years; median 42.0 age range, 24-65 years) 53 invasive cancers diameter, 5.0 cm; 4.2 diameter 2.0-13.3 cm) who had undergone were...
The purpose of this article is to compare the diagnostic performances shearwave and strain elastography for differentiation benign malignant breast lesions.B-mode ultrasound shear-wave were performed in 150 lesions; 71 malignant. BI-RADS final assessment, elasticity values kilopascals, scores on a 5-point scale assessed before biopsy. results compared using area under receiver operating characteristic curve (AUC).The AUC was similar that (0.928 vs 0.943). combined use B-mode either technique...
To investigate factors influencing the quality of ultrasonographic (US) elastography in evaluation suspicious breast masses.This prospective study was conducted with institutional review board approval; written informed consent obtained. Between January 2009 and February 2009, real-time US 312 masses (245 benign, 67 malignant) performed 268 consecutive patients (mean age, 45.7 years ± 10.2 [standard deviation]) prior to US-guided core biopsy. Five radiologists who had examinations assessed...
To retrospectively review the mammograms of women with breast cancers detected at screening ultrasonography (US) to determine reasons for nondetection mammography.This study received institutional board approval, and informed consent was waived. Between 2003 2011, a retrospective database revealed 335 US-depicted in 329 (median age, 47 years; age range, 29-69 years) Breast Imaging Reporting Data System density type 2-4. Five blinded radiologists independently reviewed whether findings on...
The purpose of this study was to evaluate the diagnostic potential sonoelastographic strain index for differentiation nonpalpable breast masses.Ninety-nine masses (79 benign and 20 malignant) in 94 women (mean age, 45 years; range, 21-68 years) who had been scheduled a sonographically guided core biopsy were examined with B-mode sonography sonoelastography. Radiologists performed biopsies analyzed sonograms provided American College Radiology Breast Imaging Reporting Data System categories....
Abstract Purpose: To investigate whether a correlation exists between perfusion parameters obtained from dynamic contrast‐enhanced (DCE) magnetic resonance imaging (MRI) and prognostic factors or immunohistochemical subtypes of breast cancers. Materials Methods: Quantitative (K trans , k ep v e ) 70 invasive ductal carcinomas were using DCE‐MRI as postprocessing procedure. Correlations factors, including tumor size, axillary nodal status, histologic grade, nuclear expression estrogen...
Purpose To evaluate the additional value of shear-wave elastography (SWE) to B-mode ultrasonography (US) and determine an appropriate guideline for combined assessment screening US-detected breast masses. Materials Methods This study was conducted with institutional review board approval, written informed consent obtained. From March 2010 February 2012, US SWE were performed in 159 masses before biopsy. For each lesion, Breast Imaging Reporting Data System (BI-RADS) category on images...
Background In patients who are expected to achieve axillary pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC), omission of lymph node (LN) dissection could prevent morbidity and complications. Purpose To develop a clinical model predict residual LN metastasis in with clinically node-positive breast cancer NAC by using MRI US. Materials Methods this retrospective study, women were treated following surgery between January 2015 September 2017 included. The randomly...
Background There is an increasing need to develop a more accurate prediction model for pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC) in breast cancer. Purpose To nomogram based on MRI and clinical-pathologic variables predict pCR. Materials Methods In this single-center retrospective study, consecutive women with stage II–III cancer who underwent NAC followed by surgery between January 2011 December 2017 were considered inclusion. The divided into development cohort...
Anti-estrogen therapy has been shown to reduce mammographic breast density (MD). We hypothesized that a short-term change in may be surrogate biomarker predicting response adjuvant endocrine (ET) cancer.We analyzed data for 1,065 estrogen receptor (ER)-positive cancer patients who underwent surgery between 2003 and 2006 received at least 2 years of ET, including tamoxifen aromatase inhibitors. MD was measured using Cumulus software 4.0 expressed as percentage. reduction (MDR) defined the...
Abstract Background Following sentinel lymph node biopsy (SLNB), the axillary recurrence rate is very low although SLNB has a false-negative of 5–10%. In ACOSOG Z0011 trial, non-sentinel positive-lymph nodes were found in more than 20% dissection group; only group did not have higher rate. These findings raised questions about direct therapeutic effect SLNB. post-surgical complications including lymphedema. Considering advances imaging modalities and adjuvant therapies, role early breast...
Background Little is known regarding findings at imaging associated with survival in patients luminal breast cancer treated neoadjuvant chemotherapy (NAC). Purpose To determine the relationship between (MRI, US, and mammography) clinical-pathologic variables predicting distant metastasis-free (DMFS) overall (OS) NAC. Materials Methods In this retrospective study, consecutive women who underwent NAC followed by surgery were identified from registries of two hospitals. Women one hospital...
