Abstract

In 49 patients who had pelvic abnormalities, breath-hold T2-weighted fast-recovery (FR)-fast spin-echo (FSE) (imaging time = 24 sec) and nonbreath-hold FSE MR images (2 min 8 sec) were compared qualitatively (on a four-pointscale) and quantitatively (using signal-to-noise ratios (SNRs) and contrast ratios (\ SIs of the lesions-SIs of the myometrium \ /SIs of the myometrium)). Motion artifacts were reduced on breath-hold FR-FSE (3.8:3.2 = breath-hold FSE:nonbreath-hold FSE, P < 0.01) and image quality was comparable (3.8:3.7, NS). In all patients, pathology (leiomyoma [N = 26], adenomyosis [N= 10], endometrial carcinoma [N = 8], and ovarian cystic lesions [N = 21])was recognized with comparable lesion conspicuity (3.8:3.7, NS) and betterdelineation of the structures (3.9:3.6, P < 0.05) on the FR-FSE images. There was no significant difference in contrast ratios, although SNRs (e.g., myometrium 18.3:25.8, P < 0.01) were better and the uterine zonal anatomy was recognized better on the nonbreath-hold FSE (3.4:3.7, P < 0.05). These differences did not affect the diagnosis. Breath-hold FR-FSE provides the benefits of motionless Imaging and a short examination time, although lower SNRs were noted. J. Magn. Reson.
