Detection and characterization of focal hepatic lesions by T(2)-weighted imaging: comparison of navigator-triggered turbo spin-echo, breath-hold turbo spin-echo, and HASTE sequences

Abstract

The aim of this study is to evaluate the diagnostic performance of T(2)-weighted (T(2)-w) images obtained using navigator-triggered turbo spin-echo (TSE), breath-hold TSE (BH-TSE), and BH haft-Fourier single-shot TSE sequences for the detection and characterization of focal hepatic lesions. Two blinded reviewers independently analyzed three types of T(2)-w image sets totaling 86 solid and 75 nonsolid lesions in 59 patients. Receiver operating characteristic curves were established to analyze reviewer and sequence results. Crown Copyright (C) 2009 Published by Elsevier Inc. All rights reserved.
