Water/Fat Separation MR Improves Optical Breast Imaging MR Water/Fat Separation Improves Optical Breast Imaging

Background Optical imaging may be added to MR mammography to provide absolute concentration images of oxygenated and deoxygenated hemoglobin, water, and other endogenous and exogenous molecular agents. This is beneficial because hemoglobin and tissue oxygenation have been shown in several studies to have high specificity to breast cancer [1]. This combined optical/MR instrument has been shown t...

Combining diffusion-weighted MR imaging with Gd-EOB-DTPA enhanced MR imaging improves the detection of colorectal liver metastases

Introduction: In patients with colorectal cancer, accurate assessment of the size, location and segmental distribution of liver metastases on a per-lesion basis is critical for treatment planning. Diffusion-weighted MR imaging (DW-MRI) has a high sensitivity and specificity for liver metastasis detection [1-3]. Combining DW-MRI with T1-weighted imaging after liver specific contrast medium Magaf...

MR imaging of parotid tumors: typical lesion characteristics in MR imaging improve discrimination between benign and malignant disease.

BACKGROUND AND PURPOSE The surgical approach to parotid tumors is different for benign and malignant neoplasms, but the clinical symptoms do not correlate well with histology. Difficulties in tumor classification also arise in imaging modalities, in which sonography has the lowest and MR imaging, the highest accuracy. The purpose of this study was to review our experience using conventional MR ...
