Readout-segmented Echo-planar Imaging Improves the Diagnostic Performance of Diffusion-weighted MR Breast Examinations at 3.0 T

Abstract

DW imaging based on readout-segmented echo-planar imaging provided significantly higher image quality and lesion conspicuity than single-shot echo-planar imaging by reducing geometric distortions, image blurring, and artifact level with a clinical high-field-strength MR imager. Thereby, readout-segmented echo-planar imaging reached a higher diagnostic accuracy for the differentiation of benign and malignant breast lesions.

MRI characterization of brown adipose tissue in obese and normal-weight children

“…Ideally, ten or more b values are needed for better fitting performance. To further optimize diffusion-weighted imaging for BAT/BRITE characterization, faster and more robust DWI sequences, such as multi-shot EPI [40] and zoomed-DW EPI [41,42], may be needed to obtain multiple b value acquisitions to improve signal fitting accuracy.…”

Improved Differentiation of Benign and Malignant Breast Tumors with Multiparametric 18Fluorodeoxyglucose Positron Emission Tomography Magnetic Resonance Imaging: A Feasibility Study

“…MP 18 FDG PET-MRI datasets were assessed according to the following criteria. Both readers, in consensus, determined the probability of malignancy for MP 18 FDG PET-MRI data as previous studies have shown very good intra-and interobserver agreement by using the following evaluation of each imaging parameter (17,20). The readers were aware that the patients had a breast tumor, but they were provided with neither the previous mammographic and sonographic imaging data nor the histopathologic results.…”

“…DCE-MRI of the breast provides high-resolution anatomic information and enables the depiction of increased microvascular density and capillary leaks in malignant breast tumors as a marker of neoangiogenesis (29). DWI depicts cellular diffusivity, which is typically restricted in malignant tissue (7,20). 3D 1 H-MRSI detects elevated levels of the metabolite choline as a marker of an increased cell membrane turnover (6).…”

Detection of cholesteatoma: High-resolution DWI using RS-EPI and parallel imaging at 3 tesla

“…This method provides images with less artefacts and higher resolution for the evaluation of brain, brain stem and the breast [11][12][13]. However, to the best of our knowledge, its effectiveness in the evaluation of middle-ear cholesteatoma has not been established, yet.…”
