Abstract

Purpose. The objective of this study was to compare conventional breast magnetic resonance imaging (MRI) with breast MRI acquired with the sensitivity-encoding (SENSE) technique on a 1.5-T MRI scanner in the same patient, on the basis of image quality and kinetics analysis. Materials and methods. Thirty-one patients with suspicious mammography and US findings were included in the study. Conventional breast MRI consisted of the following sequences: T1 (matrix, 288x512); T2 (matrix 225x512); short tau inversion recovery (STIR) (matrix 320x224) and dynamic T1 [2D fast-field echo (FFE)] (matrix 256x512; temporal resolution =80 s). The SENSE technique included the following sequences: T1 (matrix 512x512); T2 (matrix 512x512); short-tau inversion recovery (STIR) (matrix 320x224); dynamic T1 (3D FFE) (matrix 512x512, with a temporal resolution ≤70 s). Image quality was graded on a four-point scale, and the mean scores given to each sequence were compared between the two protocols. The relative enhancement rates and the qualitative features of the signal intensity (SI)/time curves were also compared between the two protocols. Results. The readers found 64 contrast-enhanced lesions in 31 patients. Nineteen patients had a total of 27 malignant lesions. In the remaining 12 patients, 37 benign lesions were found. No significant differences between the two protocols were observed with regard to the mean relative enhancement rates and the qualitative features of the SI/time curves. In detail, the mean image quality scores were higher for SENSE imaging (p
