Non echo planar, diffusion-weighted magnetic resonance imaging (periodically rotated overlapping parallel lines with enhanced reconstruction sequence) compared with echo planar imaging for the detection of middle-ear cholesteatoma.

摘要

Dear Sirs, We read with great interest the above paper by Kasbekar et al,In the conclusion of this paper, it is stated that 'Casselman and De Foer et al. continue to report on their success with their particular non echo planar imaging sequences. Further studies should assess the reproducibility of results, using Casselman and De Foer and colleagues' protocols and MRI machines'. Our group was the first to describe, in 2006, the half-Fourier acquired single-shot turbo spin-echo diffusion-weighted magnetic resonance imaging (MRI) sequence, and to compare it to the routinely used echo planar diffusion-weighted sequences, both in patients prior to first stage surgery and in patients prior to 'second-look' surgery for residual cholesteatoma. In this last, 2008 paper, we concluded that second-look surgery could be replaced by the use of half-Fourier acquired single-shot turbo spin-echo diffusion-weighted sequences.
