Spiral 2D T2-Weighted TSE Brain MR Imaging: Initial Clinical Experience

Spiral 2D T2-Weighted TSE Brain MR Imaging: Initial Clinical Experience ORIGINAL RESEARCH ADULT BRAIN Spiral 2D T2-Weighted TSE Brain MR Imaging: Initial Clinical Experience E. Sartoretti, S. Sartoretti-Schefer, L. van Smoorenburg, C.A. Binkert, A. Gutzeit, M. Wyss, and T. Sartoretti ABSTRACT BACKGROUND AND PURPOSE: Spiral MR imaging may enable improved image quality and higher scan speeds than Cartesian trajec- tories. We sought to compare a novel spiral 2D T2-weighted TSE sequence with a conventional Cartesian and an artifact-robust, non-Cartesian sequence named MultiVane for routine clinical brain MR imaging. MATERIALS AND METHODS: Thirty-one patients were scanned with all 3 sequences (Cartesian, 4 minutes 14 seconds; MultiVane, 2 minutes 49 seconds; spiral, 2 minutes 12 seconds) on a standard clinical 1.5T MR scanner. Three readers described the presence and location of abnormalities and lesions and graded images qualitatively in terms of overall image quality, the presence of motion and pulsation artifacts, gray-white matter differentiation, lesion conspicuity, and subjective preference. Image quality was objectivized by measuring the SNR and the coefficients of variation for CSF, GM, and WM. RESULTS: Spiral achieved a scan time reduction of 51.9% and 21.9% compared with Cartesian and MultiVane, respectively. The num- ber and location of lesions were identical among all sequences.
