Metabolite-Specific Echo Planar Imaging for Preclinical Studies with Hyperpolarized ¹³C-Pyruvate MRI [PDF]

Tomography, 2023
Metabolite-specific echo-planar imaging (EPI) sequences with spectral–spatial (spsp) excitation are commonly used in clinical hyperpolarized [1-13C]pyruvate studies because of their speed, efficiency, and flexibility.

Comparison of readout-segmented echo-planar imaging and single-shot echo-planar imaging in the fetal brain. [PDF]

Transl Pediatr
The diagnostic value of diffusion-weighted imaging (DWI) in fetal brain imaging has been established for various brain lesions, yet conventional DWI single-shot echo-planar imaging (SS-EPI) suffers from distortion and artifacts. Readout Segmentation of Long Variable Echo-trains (RESOLVE) is an advanced technology that can produce better image quality ...

Readout-segmented echo-planar imaging and conventional single-shot echo-planar imaging for determining cervical cancer image quality, lymphovascular space invasion, and lymph node metastasis status: a comparative study [PDF]

Diagnostic and Interventional Radiology
PURPOSE: Diffusion-weighted imaging (DWI) using single-shot echo-planar imaging (ss-EPI) is prone to artifacts, geometric distortion, and T2* blurring. Readout-segmented echo-planar imaging (rs-EPI) may improve image quality in the DWI of cervical cancer
