Readout-segmented EPI for rapid high resolution diffusion imaging at 3T

Detection of cholesteatoma: High-resolution DWI using RS-EPI and parallel imaging at 3 tesla

“…The basic methodology for the RS-EPI technique was introduced by Porter et al [8]. Our preliminary study showed that RS-EPI method could provide higher spatial-resolution and lesion-visibility with less distortion and artefacts than SS-EPI technique, which is relevant with other studies [19][20][21]. Analysing the presence of cholesteatoma scores of our study showed that RS-EPI technique differs significantly from SS-EPI technique and could detect cholesteatoma in higher number of patients.…”

Reduced Field-of-View Diffusion Imaging of the Human Spinal Cord: Comparison with Conventional Single-Shot Echo-Planar Imaging

“…30,31 Thus, prior investigators have developed EPI-based and other methods that address this issue, including navigated fast spin-echo, 3 line scan imaging, [32][33][34][35] propeller-based imaging, [36][37][38] and interleaved 4,39,40 and parallel EPI 28,41,42 approaches. For all of the non-single-shot approaches, readouts from several excitations are combined to create the final image; this incurs penalties in scan time and requires compensation for dephasing due to patient motion during diffusion-sensitizing gradients.…”

Clinical Evaluation of Reduced Field-of-View Diffusion-Weighted Imaging of the Cervical and Thoracic Spine and Spinal Cord

“…Advanced EPI-based techniques have thus been developed to address this issue, including interleaved (or multishot) EPI 7,9,10 and parallel imaging. [11][12][13] However, these techniques also have shortcomings, 14 and this has limited clinical diffusion-weighted imaging of the spine and spinal cord.…”
