Human Breast Lesions: Characterization with Contrast-enhanced in Vivo Proton MR Spectroscopy—Initial Results

Abstract

Choline can be reliably detected in less than 45 minutes in large contrast-enhanced breast lesions by using a multiecho point-resolved spectroscopic protocol. The presence of water-soluble choline metabolites obtainable with (1)H MR spectroscopy could complement MR imaging findings to improve specificity and to reduce the number of unnecessary biopsies.
