Abstract

Purpose: The value of the fast half-Fourier single-shot turbo spin echo (HASTE) sequence in T2-weighted MRI of the kidney was evaluated as a substitute for the conventional turbo spin echo (TSE) sequence. Method: Forty-five patients with suspected abnormalities of the kidney underwent MRI with a 1.5 T system. Breath-hold HASTE and respiratory-triggeredTSE sequences were performed. Qualitative and quantitative analyses were performed for comparison of these sequences. Results: The signal-to-noise ratio (SNR) with HASTE was higher than that with TSE. The lesion-to-kidney contrast-to-noise ratio for solid masses withHASTE was almost equal to that with TSE. For cystic masses, the CNR with HASTE was significantly higher than that with TSE (p < 0.05). Respiratory and chemical shift artifacts were significantly smaller on HASTE than on TSE (p < 0.01). However. the blurring artifact was higher on HASTE than on TSE (p = 0.01). Conclusion: The HASTE sequence generates high contrast images and is free of motion and chemical shift artifacts, with much better time efficacy. Thesequence provides comparable diagnostic information to TSE sequences.
