Female Pelvis: MR Imaging at 3.0 T with Sensitivity Encoding and Flip-Angle Sweep Technique¹

¹ From the Department of Radiology, University of Bonn, Sigmund-Freud-Strasse 25, D-53105 Bonn, Germany (N.M., H.H.S., C.K.K., G.L., M.v.F., F.T.); and Philips Medical Systems, Best, the Netherlands (J.G.). Received May 25, 2005; revision requested July 21; revision received December 2; accepted January 6, 2006; final version accepted January 31. Address correspondence to N.M.

This study had institutional review board approval; all 33 patients (mean age, 47 years ± 16 [standard deviation]) gave informed consent. The aim was to prospectively evaluate the diagnostic image quality yielded by a 3.0-T T2-weighted turbo spin-echo magnetic resonance imaging sequence with a very short imaging time versus that yielded by a standard 3.0-T sequence at imaging of the female pelvis. Signal-to-noise ratio and delineation of gynecologic disorders were approximately equal between the two sequences. The majority of tissue contrasts were comparable, but contrast between fluid and muscle was significantly higher and motion artifacts were reduced (P < .001 for both) with the short imaging time sequence. The fast sequence maintained or improved image quality and thus seems to be advantageous for uncooperative patients.
