H-MR spectroscopy of suspicious breast mass lesions at 3T: a clinical experience.

Objectives: To test 3T proton magnetic resonance spectroscopy (H-MRS) for breast mass lesions.

Methods: Patients with BI-RADS 4-5 lesions at mammography/ultrasound were prospectively enrolled. After contrast-enhanced breast MRI, single-voxel MRS (point-resolved volume selection, PRESS); pencil-beam shimming; volume of interest 1 cm; TR/TE = 3000/135 ms) was performed.

High-field MR spectroscopy in the multiparametric MRI evaluation of breast lesions.

Introduction: The aim of this work was to assess the role of 3T-MR spectroscopy (MRS) in the multi-parametric MRI evaluation of breast lesions, using a pattern-recognition based classification method.

Methods: 291 patients (301 lesions, median 2.3cm) were enrolled in the study (age 18-85y, mean 54.
