Abstract

The purpose of this study is to compare the image quality of T2-weighted fast spin echo (FSE) with fat suppression and conventional spin echo (CSE) magnetic resonance images (MRI) using by phased-array multicoil (MC) and body coil (BC) in each sequences for evaluating focal solid lesions of liver. T2-weighted FSE and CSE images using by MC and BC in a 1.5T superconductive MRI system were performed on 16 patients. The images were quantitatively evaluated by hepatic signal-to-noise ratio (SNR) and lesion contrast-to-noise ratio(CNR) and qualitatively evaluated by lesion conspicuity, lesion detection, and artifact. Statistical analysis was performed using by Wilcoxon signed-ranks test. The results are as follows. Hepatic SNR and lesion CNR were highest on MC-FSE (p<.05) and were similar on MC-FSE and BC-FSE without statistical significance, but significantly higher than on BC-CSE. Lesion conspicuity was significantly better on MC-FSE than on BC-CSE (p<.05), but no significant difference on other images. Lesion detectability was no significant difference on four images. Lesion artifact was minimal on MC-FSE and maximum on BC-CSE, but no statistically difference on other images. In conclusion, hepatic SNR, lesion CNR, and lesion conspicuity are highest on MC-FSE in the evaluation of hepatic solid lesions. MC-FSE is a potentially useful T2-weighted image for evaluating hepatic solid lesions
