The dynamic course of spontaneous muscular contractions assessed using multiple-point acquisition in diffusion-weighted stimulated echo imaging.

ABSTRACT:

Purpose

The temporal course of spontaneous mechanical activities of musculature (SMAMs) is investigated using a novel multiple-point diffusion-weighted stimulated echo imaging sequence (MP-DW-STE) with adapted spatial and temporal resolution. For this purpose, different sequence settings and measurement parameters are applied.

Methods

A single-shot MP-DW-STE imaging sequence with multiple signal rephasing by small flip angle RF pulses was developed to acquire image series during spontaneous muscle contractions with duration of several hundred milliseconds. Measurements were conducted on an incoherent motion phantom and in the calf muscles of eight healthy volunteers. The number and cross-sectional area of SMAM visualizations as well as the contractile behavior in terms of on
