Purpose: The purpose of this work was to evaluate the performance of reduced-field-of-view (FOV) acquisition and retrospective distortion correction methods in decreasing distortion artifacts for breast imaging. Coverage of the axilla in reduced-FOV DW magnetic resonance imaging (MRI) and residual ...
However, these examinations report many indeterminate studies with a low probability of being malignant, i.e., BIRADS 3 and 4A. This prospective study aims to evaluate the value of breast magnetic resonance imaging (MRI) to clarify the BIRADS categorization of indeterminate mammography or ...
Method: Pre- and post-NACT MRI reports were compared with final surgical histology to assess the accuracy of MRI in predicting the presence or absence of residual breast and axillary disease. Results: (1) Out of 60 patients, 19 achieved complete pathological response (PCR) with no residual inv...
Women with dense breasts often undergo conventional magnetic resonance imaging (MRI) despite its limited specificity, which may be increased by diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) and contrast. How these modalities are affected by breast density per se and their...
A McNemar test was performed to compare PET and MRI, and kappa was determined to quantify agreement of both methods. Sensitivity was 79 and 100%, specificity was 94 and 72%, and accuracy was 88 and 84% for MRI and PET, respectively. Additional metastases outside the field of view of ...
In this work, we presented an objective method to separate a breast into four quadrants, based on the nipple alone in the original MRI space coordinates, or the reoriented breast based on the nipple to the centroid line. The centroid, or the center of mass (COM), was calculated from the...
The general design of a flat surface coil for use with a vertical field MRI system is discussed. A development of the design for imaging the breast is used as a specific illustration. The phenomenon of “sympathetic resonance” is described in which transmission and reception is performed on th...

Neoadjuvant systemic therapy (NAST) followed by surgery are currently standard of care for TNBC with 50-60% of patients achieving pathologic complete response (pCR). We investigated ability of deep learning (DL) on dynamic contrast enhanced (DCE) MRI and diffusion weighted imaging acquired early ...
